Reflections from Scotland’s EIA Conference 2026

Reflections from Scotland’s EIA Conference 2026

Arabella Stewart-Leslie 16 Oct 2026
Lichfields was proud to sponsor and present at Scotland’s EIA Conference 2026, which brought together practitioners, regulators, and industry leaders to discuss the future of Environmental Impact Assessment (EIA).
The conference was attended by colleagues from across Lichfields, including Gayle Black, Neil Purvis, Heather Overhead and Dan Evans. Drawing on their collective insights and discussions throughout the day, this blog reflects on the key themes that will shape EIA practice in the future.

The key themes of the conference were ‘Innovation’, ‘Impact’ and ‘Insight’. Discussions covered topics including the importance of defining "the project" in EIA, reflections on the implications of the Raeshaw court ruling, and the topic of the moment: data centres and EIA.


Defining the project 


Brodies explored the legal and practical importance of defining "the project" within the EIA process, following the February 2026 Raeshaw court ruling. One of their key messages was that defining the project has always been a fundamental principle of good EIA practice, forming the basis on which environmental effects are identified, assessed and reported. It is not a new requirement. 

The speakers highlighted that the principles in the Raeshaw decision are long-established but have prompted practitioners, regulators and decision-makers to strengthen how projects are described and presented within EIA documentation. The discussion served as a timely reminder that defining the project underpins the entire assessment, ensuring that decision-makers have a clear understanding of what is being proposed. 


Handling uncertainty and proportionate assessments

Another interesting discussion focused on how EIA practitioners deal with uncertainty in a proportionate way. The session highlighted that dealing with uncertainty is an inherent part of the EIA process and one that practitioners must address through professional judgement.
A proportionate approach can be taken that focuses on likely significant effects and provides decision-makers with the information they need to reach an informed conclusion. By exercising professional judgement, long and complex assessments are not necessary. 
The discussion also touched on why the Raeshaw decision has attracted so much attention across the profession. The case highlights the need to assess aspects of a development where there may not yet be complete certainty, such as the delivery of a grid connection or other associated infrastructure. Such uncertainties are quite normal and the expectation remains that any likely significant environmental effects are identified and assessed in a proportionate manner. 
 

Assessment guidance and best practice

A further key theme of the conference was the importance of maintaining best practice in EIA assessment. The afternoon session focused on forthcoming guidance from the Institute of Sustainability and Environmental Professionals (ISEP) on interaction effects and cumulative effects. A commonly agreed and replicable approach to assessing these effects would be welcomed across the profession.
Additional guidance is also expected from ISEP next year on Climate Change Resilience and Adaptation for professionals coordinating EIA’s or supporting assessments. As the impacts of climate change are increasingly felt in our daily lives, this new guidance is especially timely and will also help to ensure consistency and best practice is maintained in EIA. 
 

EIA for Data Centres

Lichfields and Pulsant presented the final session of the day, exploring the growing role of data centres as critical infrastructure. Pulsant explained what data centres are and noted that, although they have recently attracted significant attention, smaller-scale facilities are already well established across the UK. Often located in business or industrial areas, these facilities form a critical part of the country's digital infrastructure. However, growing demand for cloud computing, artificial intelligence and data storage is driving the development of increasingly large "hyperscale" data centres. This rapid expansion requires planners, environmental practitioners and decision-makers to develop their understanding of the sector's environmental effects and technical requirements.
Lichfields discussed the implications of the Scottish Government's Direction of 17 September 2026, which requires data centre developments exceeding 50MW to be treated as EIA development. Developers may need to engage a broader technical team earlier in the EIA scoping process to agree the environmental topics requiring detailed assessment in the EIA Report. These may include landscape and visual impacts, transport, ecology, noise, carbon emissions, air quality and socio-economics. Early collaboration between planning, environmental and technical specialists will help identify potential effects from the outset and support efficient progress through an increasingly complex consenting environment.
 

Concluding thoughts

Scotland’s EIA Conference 2026 highlighted a profession that continues to adapt to an increasingly complex environmental and regulatory landscape. There was a clear sense of optimism about the role EIA can play in supporting sustainable development even if challenges remain around climate change, uncertainty and the delivery of proportionate assessments.
The shared commitment across the sector to improving the quality, accessibility and effectiveness of environmental assessment was particularly encouraging.  EIA remains a vital tool in ensuring that environmental considerations are embedded in decision-making and development outcomes.

New housing and the education estate: the role of Education Assessments
"Can local schools accommodate the pupils generated by new housing?"
This is a question that is frequently asked by both local planning authorities and developers when new homes are proposed. It is also a question that can create significant concern locally, with communities concerned about the impact of new development on overstretched school capacity. 
However, the relationship between housing and education is complex. In some areas, school rolls are falling and new housing could help support the long-term sustainability of local schools. In others, schools are already under pressure and further housing growth could add to capacity issues. 
Understanding this relationship, and how it may change over time, is therefore important when planning for new housing.
 
A change in demand
The number of school-age children is changing across the UK. The Institute for Fiscal Studies (IFS) forecasts that the number of children aged under 16 in the UK will fall by around 800,000 between 2025 and 2035, with declines of 6% in England, 8% in Scotland, 10% in Wales and 15% in Northern Ireland[1]. 
This is already being reflected in school rolls. Pupil numbers fell in England[2], Scotland[3] and Wales[4] between 2024 and 2025 and further declines are expected in all three countries in the next 10 years. 
At the same time, significant pressures on school capacity remain in some areas. In England, there were around 1.2 million unfilled school places in 2024/25, which is the equivalent of 13% of capacity, while 14% of primary schools and 19% of secondary schools were at or above capacity[5].
This demonstrates the complex relationship between housing and education infrastructure and how demand can differ across areas. As well as new housebuilding, there are several other factors that can influence the demand for school places: 
 
 
Population change
  
A school operating close to capacity today may see its roll decline as the number of children in the local population falls. While this can create additional capacity, sustained falls in pupil numbers can also create challenges for the long-term sustainability of schools, particularly where they have fewer pupils to support. New housebuilding can therefore help sustain existing schools in areas where pupil numbers are falling; Equally, a school with significant capacity today may face pressure in the future as the population increases in the area.
 
 
Household turnover
 
Families often stay in their homes for a number of years meaning that an initial increase in demand generated by new housebuilding may not be sustained over the longer term.  This is particularly the case once children enter the school system. Anecdotal evidence suggests many families remain in the same home from the time their children are young, through to adulthood, with the children eventually leaving the family home while the parents remain.
  
 
School popularity
 
Areas with highly-ranked schools often experience greater demand for family housing, with families often choosing to live in these areas. This can mean that some schools experience pressure for places while capacity remains available elsewhere in the school estate.
 
 
This means that the education impact of new housing cannot be calculated by simply applying a pupil yield to the number of homes proposed. The impact needs to be considered alongside the existing school estate, future demographic change and other planned development in the area.
 
Where Education Assessments can help
Education Assessments can establish the likely pupil generation from a proposed development and consider this alongside existing and projected school capacity, demographic trends and other planned housing. 
They can help to answer questions such as:
  • Can existing local schools accommodate additional pupils generated by new housing development?
  • Are demographic trends likely to influence future school capacity?
  • Is additional investment or expansion likely to be required?
  • What are the likely education infrastructure implications of the proposed development?
This evidence can support decision making at different stages of the planning process. 
For local planning authorities, Education Assessments can inform Local Plan evidence bases, help assess proposed housing allocations and identify future education infrastructure requirements. They can help authorities understand where housing growth can be accommodated within the existing school estate, where new development could support existing schools and where additional infrastructure may be required.  
For developers, assessments can support site promotions and planning applications by identifying potential education issues at an early stage. They can also provide an important evidence base when considering education contributions and whether the level of mitigation sought is proportionate to the impact of the development. 
Approaches to calculating education contributions vary significantly between planning authorities across the UK. In some areas, contributions are sought to address wider education capacity issues rather than the direct impact of an individual development, which can result in viability concerns. 
Where existing schools have capacity, or where demographic change is expected to reduce demand, it is important that this is properly recognised when considering the infrastructure implications of new housing. Understanding the actual impact of a proposal is therefore important when determining what mitigation is necessary and what represents a fair and reasonable contribution. 
Considering education infrastructure early in the process allows developers and local authorities to identify potential issues, explore mitigation where necessary and support more efficient decision making.
 
Lichfields approach
Lichfields prepares Education Assessments for housing developments across the UK, supporting site promotions, Local Plan evidence,  planning applications and developer contribution negotiations.
While the overall principles of education planning are consistent across the UK, forecasting models, pupil product ratios and planning policy requirements can all differ. In Scotland, England and Wales, local planning authorities each apply their own approaches to understanding education capacity.
Our approach takes this into account and combines population analysis, housing growth, school capacity data and local policy to provide clear, evidence-based assessments that reflect the specific circumstances of each area. 
To explain our methodology, we have developed an Education Assessment Toolkit, which sets out the approach we take when assessing the education implications of housing development. The toolkit explains the evidence we consider, the process we follow and the principles that underpin our assessments. 
Whether supporting a strategic housing allocation, preparing a planning application or assessing the education implications of a proposed housing development, our approach is designed to provide useful insights to allow constructive discussions between developers and local planning authorities.
As population, housing delivery and school capacity change, understanding where education demand will arise and the impact of new housing will remain an important part of planning for sustainable communities. 
We will continue to share further insights on education planning, including the relationship between demographic change, housing delivery and future demand for school places in the following months.

Rewiring the High Street: Latest announcements on £210m regeneration package
The Ministry of Housing, Communities and Local Government (MHCLG) confirmed a £210 million capital funding injection on 25 September 2026 aimed at reversing the decline in vacancies across England's town centres. Communities Secretary Angela Rayner then referred to it in her speech at the Labour Party Conference announcing “…a new fund to breathe life back into our high streets. Our town centres should be thriving, the heart of a place where people enjoy a family day out or an evening with their mates – with cafes, shops and pubs open for business, and jobs for local people too”.
 
Reflective of the government’s commitment to backing communities, this latest announcement continues the policy shift toward devolution through funding support and local controls for bringing boarded-up and long-vacant high-street property back into productive use.

 

The Funding Offer

 

The capital funding package comprises the following targeted funding streams:
 
  1. Derelict Buildings Fund (£125m): Allows local authorities to acquire, remediate, and repurpose unsound or long-term vacant commercial buildings - such as redundant department stores, cinemas, and shopping centres - into more tailored local uses such as shared workspaces, health centres or civic spaces.
     
  2. Community Asset Rescue Scheme (£65m): Expands existing localised intervention approaches (such as the Pride in Place initiative) to safeguard valued local assets, such as pubs and shops, from being lost.
     
  3. High Street Rental Auctions and Co-operative Infrastructure (£20m): Splits funding equally between the scaling up of High Street Rental Auctions (HSRAs) programme to penalise landlord inertia on properties vacant for over 12 months, and dedicated support for establishing and growing co-operatives. 

 

Funding Stream
Allocation
Purpose
Derelict Buildings Fund £125 Million To support local authority asset acquisition, remediation, and conversion of important civic and community buildings.
Community Asset Rescue Scheme £65 Million Micro-level grants to safeguard local social infrastructure, clubs, and heritage spaces.
High Street Rental Auctions Programme £10 Million Introduced by the Levelling Up & Regeneration Act 2023. Provides powers to local authorities to auction properties to find tenants where they are vacant for over a year in a two year period in designated areas.
Co-operative Development Programme £10 Million Help mayors and strategic authorities to set up and run more mutual and co-operative businesses.
 
This funding announcement directly links with the broader agenda to empower regional strategic authorities and the mayors. By decentralising fiscal retention capabilities - such as allowing select mayoral authorities to retain localised proportions of income tax from 2028 - the government has identified high street regeneration as an opportunity for regional macro-economic growth.
 
Whilst a £210 million allocation sounds a lot and may inject some vital capital momentum, it is funding from an existing pot, so it is not new money. Nevertheless, many local areas know the assets that this funding could help, like in Swindon, where the derelict Mechanics' Institute and Oasis Leisure Centre could be regenerated with the Derelict Building Fund. Converting deeply compromised structural formats like mid-century cinemas or multi-story shopping centres into decentralised healthcare hubs or civic spaces comes with its challenges. These buildings usually have significant upfront capital requirements which this funding will not be sufficient in addressing and there may also be viability questions around any future alternative use. Local authorities will often need to secure institutional development partners to stretch this funding across various phases to deliver long term change. On this basis, it may be some time before we see much improvement in our high streets.
 
Any immediate results playing in to Andy Burnham’s agenda of delivering ‘growth in every postcode’ and rejuvenating high streets, may come from the formalising of HSRAs. If local authorities can identify landlords holding long-term vacant assets or portfolios of assets, the ‘threat’ of an auction to find them a tenant may trigger some proactive repositioning before the compulsory auction process commences. Broxtowe Borough Council is one such authority who has claimed to use the new powers successfully[1]. North Northamptonshire Council has also been consulting on designating part of Wellingborough town centre for the HSRA programme[2].
 
Whether this injection of funds and controls to tidy up our high streets makes a noticeable change remains to be seen. Some of these funding announcements have limited details on the application process, eligibility or conditions that might be attached to them.
 
It will take experienced local authorities to navigate the application processes and understand the pooling of funds that might be necessary to secure the money to deliver on their ideas, against a backdrop of stretched resourcing. Once the funding is received, it also requires local authorities and their partners to be skilled in using a mix of planning levers to deliver change before any spending conditions lapse.
 
Later this year, the government will go further still, publishing a full high streets strategy which should be a comprehensive guide on how it all fits together, eligibility and how the funding might be allocated, which is eagerly awaited.

Co-living policy: Shared Living beyond London
Changing Context
Lichfields’ blog series has charted the rise of co-living in London over the last half-decade, to its current status as an established form of housing against the backdrop of an otherwise challenging residential market. Several years in, policy has now largely caught up with these applications, with recognition in most London boroughs’ local plans, positive adopted and emerging London Plan policy and established standards set out in London Plan Guidance.
Beyond the capital, the same pattern is beginning to appear, though it is still early days. Operational co-living schemes and applications have begun to spring up in cities across the country, including Manchester, Leeds, Brighton, Bristol and Birmingham, but at present, policy recognition is sparse. As a result, applications can face extensive negotiation to establish the land use principle and basic elements of co-living form, such as room sizes and amenity provision, all of which, in London, are grounded in policy.
This is set to change, however. The transition to a new plan-making system has brought about a flurry of plan-making, with approximately 90 local planning authorities (LPAs) either set to submit a plan this year under the previous system or ordered to commence plan-making this year under the new system, according to Lichfields’ estimates. With some of these LPAs responding to their first co-living applications, co-living policy is beginning to populate these emerging local plans for the first time nationwide. 
The recently published NPPF (August 2026) adds to this policy momentum. For the first time adopted national policy recognises co-living as a specialist form of accommodation, and sets out a specific definition and provides a positive national platform for co-living.
  
In which areas is co-living policy appearing?
Lichfields has studied the trend of co-living policy outside of London. We have looked at the state of policy coverage in adopted plans, emerging plans, and supplementary planning documents (SPDs) in the 84 LPAs most likely to see co-living activity. This comprises the 35 most populous urban areas outside of London, university towns, and commuter towns around London.
Of these 84 authorities, only Salford and Watford refer to co-living in their adopted local plans. Four more authorities provide co-living guidance in SPDs (Birmingham, Leeds, Brighton and Hove, Chelmsford[1]). In combination, this policy and guidance equates to just 7 percent of the LPAs reviewed leading this new policy frontier. This is less than 2% of all LPAs in England. 
When emerging plans and draft SPDs are taken into account, however, the proportion of LPAs which discuss co-living in policy and guidance grows to more than 25 percent of these reviewed authorities (6% across all LPAs in England). This trend is concentrated in the largest cities: of the ten largest cities outside London, seven include co-living in their emerging local plans or guidance, up from just two (Salford and Watford) at present. These cities are: Birmingham, Leeds, Liverpool, Sheffield, Bristol, Coventry and Nottingham.
 
 
Co-living policy recognition is therefore becoming more common, although it is still focused in a relatively small number of areas in the context of such a significant opportunity. The language of emerging plans does indicate the momentum of this trend however: some emerging plans borrow or take as a starting point policies adopted elsewhere, aiding policy formulation and lending a common pattern to co-living policies emerging across the country. The rest of this blog covers these patterns in more detail.
  
How do emerging plans approach co-living?
In general, emerging plans take a positive approach to co-living. As opposed to London, where some authorities have sought to introduce policies intended to restrict co-living, the tone is supportive in almost all emerging plans elsewhere.
Plans tend to take a strict approach to locational requirements, targeting co-living in accessible locations and established centres. But, provided these locational considerations are met, authorities are encouraging of co-living schemes. In particular, many plans consider co-living to be a more affordable alternative to renting conventional C3 housing and welcome the use accordingly.
Beyond this generally receptive baseline, plans differ greatly in the level of detail they provide for co-living policy. Some plans stop there, with three plans referencing co-living but not providing any policy details[2], while other plans cover co-living either alongside other forms of specialist accommodation (typically build-to-rent and student accommodation) or in a bespoke policy. Though these policies all cover similar themes – location, affordable housing, space and amenity standards, and management policies – the level of detail provides more variability than the policy approach itself, as set out below.
  
Location and need requirements
In the 84 authorities reviewed, location typically emerged as the biggest concern for co-living. Nearly 80 percent of authorities with policy or guidance provided explicit location requirements, all of these directing co-living towards well-connected areas, town centres, or both. This makes sense: co-living is typically large scale, high-density development most appropriate in areas well-served by public transport, and Lichfields’ research into London schemes has found that most of these are found in highly accessible locations. Policies typically encourage cycle parking provision, with a minority of plans specifying or encouraging that co-living provide only accessible parking spaces, making accessible locations yet more important.
Nearly a quarter of plans further specify that co-living should not jeopardise the delivery of conventional housing. These policies typically state that applications on land currently used or allocated for C3 housing will not be approved, which, when coupled with town centre requirements, shrinks the pool of available land for co-living quite substantially. Lichfields’ view is that this approach is not necessarily appropriate in all instances. Whilst there is clearly a pressing need for C3 homes, this is also true off all forms of residential accommodation, including co-living, which has an important role to play in meeting local housing needs. A ‘C3 first’ approach runs the risk of preventing sites which could be better suited for co-living accommodation, or a mixture of both C3 and co-living, from coming forward. 
Six authorities – half of which also fall into the previous group adopting a ‘C3 first’ approach – require co-living applications to demonstrate need, while four set limits on co-living concentration. These limits are typically based on planning judgements, such as in Milton Keynes’ emerging plan, which states that co-living proposals will be supported where they “create or maintain a mixed and balanced community within the wider neighbourhood and do not result in an over-concentration of that type of home in that location”, in addition to being in highly accessible locations within settlement boundaries.
 
 
Affordable housing
Authorities differ quite significantly in their approach to affordable housing for co-living schemes, both in type and quantity. This is to be expected given that affordable housing policies respond to specific local need and housing markets. Affordable housing policies typically ask for a payment in lieu, but this is not always the case and a sizable minority of plans actively support on-site affordable housing. Whilst London boroughs typically specify that on site affordable housing alongside co-living should be separate, self-contained C3 housing, many policies outside London merely defer to their generic affordable housing policy in the context of co-living without considering the implications of this.
The level of affordable housing promoted by policy typically ranges between 20 and 35 percent, though there are exceptions to this. Birmingham’s emerging plan, for example, calls for a payment in lieu equivalent to 50 percent affordable housing (by unit), a sizeable increase from its existing SPG, which seeks 35 percent. Brighton and Cambridge set the level at 40 percent, either to be delivered on-site or through a payment in lieu, while Trafford has a sliding scale between 25 and 45 percent depending on the location. At the other end of the spectrum, Canterbury and Portsmouth do not ask for any affordable housing, considering co-living to be an affordable product in and of itself.
 
 
Space and amenity
The variation in policy detail is perhaps most evident in space and amenity policies, which is again to be expected. The London Plan Guidance (LPG) sets specific standards for floorspace and amenity expectations – a minimum room size of 18 sqm and recommended amenity space of 4 sqm per resident for the first 100 residents, tapering down to 2 sqm per resident past 400 residents. However, less than half of LPA policies outside London provide similar quantitative standards.
Of these, just three follow the LPG’s room minimum of 18 sqm, with other plans ranging from 25 to 37 sqm, in line with the nationally described space standard for a one bedroom (i.e. C3; non-co-living) flat. The LPG sets a maximum room size of 27 sqm, to avoid blurring the line with self-contained C3 flats. It is unclear whether authorities setting these large standards have fully considered the implications of conflating the floorspace expectations of co-living and C3 flats.
The more common approach, however, in just over half of policies, is to not set room standards at all, instead calling for “adequate” or “well-designed” living space. While a qualitative approach can provide welcome flexibility, in Lichfields’ experience this can cause issues at the decision-making stage, as officers and committee members may not be familiar with room standards in co-living or have access to comparable schemes. In our view, it is preferable for policy to set realistic floorspace standards for co-living units which provide some flexibility and are differentiated from the national standards for C3 flats. The approach in the LPG is appropriate. 
Quantitative standards for amenity space are fewer and further between, found in only a third of authorities’ policies. Where such policy standards do exist they tend to be more in line with LPG levels, promoting either 4.5 sqm per resident or 4 sqm tapering to 2 sqm with over 400 residents, as in the LPG.
 
Other policy issues
Plans are more consistent when it comes to building management, with most specifying that a management plan is needed and often setting minimum tenancy lengths to provide security of tenure and to avoid co-living homes from being used as hotel accommodation. Some policies also dictate that the design of co-living schemes should provide inbuilt adaptability, to allow for alternative uses with minimal conversion should a change of use be needed in the future. This issue is now being raised frequently on Lichfields co-living projects and typically requires submission of a design study to evidence a scheme’s inbuilt future proofing and adaptability should need and the market pressures change.
 
Conclusion
The present state of co-living across the country is in many ways reminiscent of the position in the capital five years ago. Applications for co-living have begun to come forward in increasing numbers, but a policy lag means that local plan policies are rare and many applicants are faced with a policy vacuum. The current state of policy in London is therefore perhaps a sign of what is to come, with policy coverage the norm in the capital and convergence between plans to allow for standardised approaches. This is likely to increase following the recent publication of the new NPPF.
Certainly, the evidence suggests this is the direction of travel. Outside of London, co-living is virtually non-existent in adopted plans, but emerging plans – especially in large cities, the majority of which have drafted co-living policies – are covering co-living in increasing number.
While many of these early policies are light on detail, the tone of these emerging plans is also encouraging. In almost all plans, LPAs are recognising the value of co-living as a more affordable alternative with some distinct advantages, in sociability and flexibility, to conventional housing.
As the policy map continues to be populated, the greater certainty provided by co-living policy in urban authorities across the UK should encourage yet more applications to come forward. This virtuous cycle of co-living policy coverage and delivery, though still in very early stage across most of the country, looks set to accelerate.
