Unlocking London’s student housing potential

Driving the future of PBSA delivery

12 Aug 2025

With over 40 higher education institutions and the largest student population in the UK, London plays a crucial role in the ongoing success of Higher Education.
 
London, however, faces a shortage of Purpose-Built Student Accommodation (PBSA) relative to the growing number of full-time students studying in the capital.
 
In October 2018, the GLA published the "Student Population Projections and Accommodation Need for New London Plan 2017"[1] which informed the London Plan 2021. The report identified a requirement for 3,500 bedrooms per year between 2016 and 2041, totalling 88,000 additional student bedrooms.
 
Since 2018 the number of PBSA beds being delivered in London has rarely met this annualised target, piling pressure on the sector to provide more PBSA in the capital. With PBSA now proving to be one of the few economically viable housing products in London and a recent in surge in PBSA approvals, London appears well positioned to begin meeting these targets.
 
Planning has a critical role to play in the delivery of PBSA in London. This Insight Focus explores the planning opportunities for PBSA in London, it examines planning policy, patterns of delivery, and development trends, before addressing common planning challenges and potential solutions. It is based on Lichfields’ research and draws upon discussions with key PBSA stakeholders.
  
    

     
 

Planning policy

Planning policy plays a crucial role in providing a proactive framework underpinning the delivery of PBSA. This section explores how supportive policy is for PBSA at the national, strategic and local level.
  
National  

The National Planning Policy Framework (NPPF) briefly addresses PBSA. It requires local planning authorities (LPAs) to consider student housing need and exempts PBSA from needing to provide 10% affordable housing.
 
Strategic policy – The London Plan

At the strategic level, the London Plan is supportive of PBSA. Policy H15 ‘Purpose Built Student Accommodation’ outlines the criteria and principles for assessing PBSA schemes.
  

Policy H15 ‘Purpose-built student accommodation'

Notably, the policy requires the provision of the majority of PBSA bedrooms to be secured through a nomination agreement by one or more higher education providers and for the maximum provision of affordable student accommodation (ASA) to be secured (with at least 35% required to follow the fast track route).
  
Overall, the London Plan promotes good quality PBSA development in the right location. It is clear that PBSA has an important role to play in meeting London’s housing need.
 
The housing need of students in London, whether in Purpose Built Student Accommodation (PBSA) or shared conventional housing, is an element of the overall housing need for London.

New London Plan
 
The Greater London Authority (GLA) is currently working on the next London Plan which is expected to be adopted in 2027. The initial consultation process on its Towards a New London Plan (2025) document closed on 22 June 2025. The document recognises the critical role that PBSA has in supporting London’s Universities and in providing quality homes for students, however, it also recognises that a balance is needed between PBSA and other forms of housing.
 
The document sought views on securing the right balance of PBSA alongside other uses as well as evidence to support the GLA’s views. In doing so, it questioned whether the London Plan should set this balance through borough wide targets or through promoting site allocations, or whether this should be left to Local Plans.
 
The document hints that ‘nomination agreements’ may now be best suited to just the affordable student accommodation. It also recognises that PBSA schemes, and other specialist housing, can help balance provision for different needs by contributing to wider affordable housing provision, signalling a potential shift away from the London Plan’s current approach.
 
 
London Plan Guidance

The GLA adopted its PBSA London Plan Guidance (LPG) on 20 November 2024. Lichfields shared its thoughts on the LPG in its blog in November 2024.
  
Overall, the guidance reiterates the shortfall in PBSA supply against London's growing student population and recognises the role PBSA has to play in meeting housing needs and supporting mixed communities and the economy.

London authorities’ approach
 
The interactive map below shows how London authorities'* Local Plan policies align with the GLA's support for PBSA. 
 
It identifies that most London authorities support PBSA in some form. However, there are variations in the planning requirements outlined in policy by each authority.
  
Most authorities have additional planning requirements or restrictive criteria beyond the requirements and objectives of the London Plan 2021. The key differences can be seen on the map.
 
From a pure planning policy perspective, the authorities with the most up to date supportive policy position in relation to PBSA are Brent, Kensington and Chelsea, Westminster, Waltham Forest and Southwark.

Number of applications


Lichfields has reviewed all PBSA applications submitted in London between 2021 (the year the London Plan was adopted) and the end of April 2025. This comprises 106 planning applications [2].
  
This research identifies that 60 PBSA planning applications were approved [3], 5 were refused and 41 are still to be determined [4].
 
Many of these schemes are mixed use developments and include additional uses at the ground floor level, including commercial spaces such as offices, retail, and community spaces that complement the PBSA use.
 
The chart below summarises these applications. 
 

 
Of the applications that have been refused, the lack of onsite affordable housing, quality of the internal accommodation and amenity space were cited by the determining planning authority as the most common reasons for refusal.
 
The following graph shows how many PBSA bedrooms have been approved each year since the adoption of the London Plan, against the annualised target of 3,500 bedrooms. Whilst permissions are not deliveries, they do indicate the potential pipeline for future years.
 

  
It is clear from the graph that since 2022, the number of PBSA permissions being granted in London has grown significantly, with 2024 proving to be a bumper year for permissions. This trend appears to be continuing for 2025, with permissions already surpassing the 3,500 target. This growth is happening at a time when planning permissions for C3 housing in 2024 dropped to a 10 year low [5]. This is likely to be a factor of the growing demand for student accommodation. The economic pressures of delivering other C3 housing in London make PBSA an attractive investment opportunity. 
 
In terms of the future pipeline, there are 41 live planning applications for over 19,600 PBSA beds currently in the system.
 
 

Patterns of development


Our analysis of PBSA developments in London revealed the following headlines:

 
 
Geographical spread
 
The map below shows the distribution of the PBSA schemes Lichfields’ has reviewed.
 
 

The map illustrates that:
 
  1. 63% of the applications for PBSA are within Inner London and 37% are in outer London. 
  2. 43% of authorities have not approved any PBSA schemes since adoption of the London Plan.
  3. 70% of approved schemes are located in authorities with Higher Education Providers.
 
Southwark approved the largest amount of PBSA bedrooms with 3,758 bedrooms, followed by the LLDC with 3,203 bedrooms and Ealing with 2,762 bedrooms.

 
 
Development quantum
 
We have found there is a broad range of scheme sizes within the approved PBSA schemes assessed, with the quantum of units ranging from 27 to 943 bedrooms. The median average is 413 bedrooms per scheme.
 
 
Scheme details
 
In this section, we discuss how PBSA schemes compare in relation to nomination agreements secured, onsite affordable housing provision, bedroom sizes and communal amenity space.
 
Nomination and affordable student accommodation
 
Our research found that 48 of the 60 approved schemes assessed sought to provide ASA on site with 33 (c.69%) of these providing at least 35% onsite ASA. All of these schemes agreed a nomination agreement or sought to agree one through a “reasonable endeavours” clause in their s106 agreement.
 
Overall, 80% of all the approved PBSA schemes agreed a nomination agreement. Of the 20% of permissions that did not agree to a nomination agreement (or did not seek to agree one), almost all of the schemes provided either onsite C3 affordable housing or a payment in lieu towards C3 affordable housing.
  
 
Affordable Housing
 
The recent PBSA LPG recognises that PBSA schemes can deliver C3 affordable housing on site in lieu of both affordable student accommodation and frequently nominated agreements.  The current London Plan consultation document recognises that delivering or contributing to C3 affordable housing could help PBSA schemes to contribute positively towards the balance of London’s housing stock.
  
Our research shows that:
 
  1. 97% of schemes provided either ASA, onsite C3, a PiL or a combination; the majority equating to a combined offer of at least 35% affordable housing. 
  2. 28% of approved PBSA schemes provided some on-site affordable housing and/or a PiL.  
  3. Only 7% of approved schemes included solely onsite C3 affordable housing without a top up of ASA and/or a PiL.
  4. The median average percentage of on-site C3 affordable housing for schemes without a PiL and/or ASA is 45%[7]
  5. £17,808.22 per bedroom is the average PiL made across the 60 schemes assessed (where no on-site AH or ASA is provided). 
  
Bedroom sizes
 
PBSA bedroom sizes vary for studio rooms, ‘twodios [8]’ and cluster rooms. Our research shows the following range of sizes within the 60 approved schemes assessed:
  

  
There is also one scheme including ‘threedios [9]’ with sizes ranging from 46 sqm to 53 sqm, and quad rooms[10], each at 81 sqm.
 
External and internal communal amenity space
 
There is generally no planning policy requirement to provide a minimum level of internal communal facilities or external amenity space for PBSA schemes. The exception is Lewisham’s emerging Local Plan which requires a benchmark of 1 sqm of internal and 1 sqm of external space per student bedroom.    
  
Our research shows that the median average areas of internal facilities and external amenity space per PBSA bedspace across the schemes assessed is:
  
  • Internal amenity – 1.5 sqm per bed
  • External amenity space – 0.6 sqm per bed
     
There is a broad range of internal amenity space provided across each development, varying between 0.8 sqm per bedroom to 7.9 sqm per bedroom.
 
The range of external amenity space across each PBSA scheme again varies, with a range between 0 sqm and 4.7 sqm per bedroom.

Concluding remarks

  
London has witnessed a substantial uptick in planning permissions for PBSA in recent years and this trend looks set to continue with a healthy current pipeline of live planning applications for PBSA. There remains though considerable unmet need for PBSA across the capital. It will be critical to ensure the policy environment remains flexible and supportive, and decision making continues to be positive to allow the momentum and growth in PBSA delivery in London to continue.
 
Our research highlights that the current policy environment is broadly supportive, and whilst there are variations, these can often be overcome to ensure that the PBSA schemes can continue to come forward.
 
Our research also sheds light on how applications address PBSA need, locational considerations, the scheme patterns around nomination agreements, ASA and onsite C3 affordable, the overall quality of PBSA schemes coming forward, how applications deal with the management of PBSA, and the patterns around PBSA rooms sizes and internal and external amenity. 
 
 

PBSA need and mixed and inclusive neighbourhoods 

 
Although, not mandatory from a planning policy perspective, our research shows that many PBSA applications include a PBSA needs assessment to strengthen an application.
 
Additionally, the London Plan encourages PBSA developments to contribute to mixed and inclusive neighbourhoods. Our research highlights that providing PBSA schemes as part of a mixed-use scheme, including the provision of on-site C3 housing for example, is an accepted way by LPAs of contributing to a mixed and inclusive neighbourhood.
 
In our experience, assessments demonstrating the PBSA need and integration of PBSA within the community are an effective way to demonstrate compliance with this requirement. 
 
  

PBSA: locational considerations

 
Our research identifies that stakeholders have varied locational preferences for PBSA, often prioritising proximity to either public transport or educational institutions.
 
Notably, over 70% of PBSA schemes are situated near higher education providers and are part of mixed-use developments. The London Plan requires PBSA schemes to be in well-connected areas, often as part of mixed-use developments, and some LPAs require PBSA in specific areas like Growth Areas or Town Centres.
 
In our research it is clear that without specific PBSA allocations, market forces will continue to drive PBSA location decisions. We consider this is important to ensure PBSA schemes continue to come forward.
 
 

Nominations, ASA and C3 affordable housing

 
From our analysis of schemes in London, many PBSA schemes are continuing to come forward with nomination agreements and ASA on site. A smaller but growing component of PBSA schemes include onsite C3 affordable housing which can contribute to the creation of mixed and inclusive neighbourhoods. In our view, the delivery of on site C3 affordable housing can make a meaningful contribution to London’s housing need and can unlock planning discussions on PBSA projects.  
 
 

Overall quality

 
The London Plan requires PBSA schemes to adhere to high-quality design standards, as outlined in Policy D3, which focuses on optimising site capacity and ensuring the quality and character of developments. Through our discussions with key stakeholders, PBSA providers have emphasised the importance of maintaining high-quality standards to attract students.
 
Alongside considering room and living space layouts/amounts, other key design considerations to improve the quality of a scheme include noise, ventilation, overheating and daylight and sunlight, as well as dual aspect rooms where possible. Early and careful consideration of planning policies and guidance are critical to a development’s success.
 
 

Management of PBSA

 
Whilst the London Plan does not require PBSA management plans, our research identifies that many Local Plan policies expect these to be submitted to support an application. These plans address concerns about student management, including deliveries and move-ins/outs. Experienced PBSA providers can use past evidence to strengthen applications, while new developers may have operators to create these plans. In our experience, well-considered management plans can help alleviate LPA concerns and enhance the credibility of an application.
 
 

Bedroom Sizes

 
Unlike other forms of housing, planning policy does not mandate the requirement for PBSA room sizes. Instead, this is entirely market driven. Notwithstanding this, our research highlights that the interquartile range for cluster rooms, which represents the largest amount of PBSA rooms approved, is fairly narrow at 3sqm with 12.5 sqm reflecting the lower quartile and 15.5 sqm reflecting he upper quartile.
 
There is a broader interquartile range for studios at 8 sqm. This is between a lower quartile of 16 sqm and an upper quartile of 24 sqm. This reflects the differing types of studio rooms available.
  
Our discussions with stakeholders highlight that this continued flexibility is essential as needs vary from location to location. In our view qualitative considerations like the overall quality of a bedroom and the quality of students’ facilities are of equal or greater importance to unit size.
 
 

Communal facilities (internal and external amenity)

 
Communal facilities both internal and external in PBSA developments are crucial for the student experience. In our research, there is only one LPA (Lewisham) which mandates specific internal and external amenity requirements. Elsewhere this is market driven. Our research identifies that the median average internal amenity is 1.5 sqm per bed and the external amenity is at 0.6 sqm per bed.
 
We consider it is important to retain flexibility in the provision of communal facilities and amenity space for students to ensure that schemes can adapt to the students’ needs.
 
 

Overarching conclusion 

 
In conclusion, the London Plan 2021, is broadly supportive of PBSA and many London Boroughs are broadly following suit. This has allowed developers to capitalise on the growing demand for student accommodation in London at a time when permissions for other forms of housing are at a ten-year low.
 
The general flexibility afforded by policy to the location of PBSA schemes, bedroom sizes and amenity sizes is allowing developers and operators to quickly adapt to changing markets and ensure their PBSA products remain attractive to the student market.
 
With the growing trend of emerging PBSA schemes providing onsite affordable housing and/or PiL, it is clear to Lichfields that value generating PBSA also provides an opportunity to provide more affordable homes across London, especially when other forms of housing are struggling to do so. 
 
Considering the emerging London Plan and its clear focus on delivering affordable homes, Lichfields considers that it is essential for the GLA to support the current PBSA momentum through continued flexibility in planning policy. This will not only ensure that London is able to meet the growing student demand, but it could also play a vital role in addressing London’s acute shortage of affordable homes.
 
Lichfields considers that the delivery of PBSA has a vital role to play in London. Maintaining the current momentum of PBSA applications in London will be essential to meeting London’s housing needs and ensuring London’s position as a leading destination for higher education.
