What are the real world implications?

Methodology
- Each calculation is based on the most recent approved housing land audit for each planning authority, the majority of which are for 2019.
- 5 year effective supply is calculated from past and projected completions programmed, in line with PAN 2/2010. Where HLAs identify a different, normally higher, 5 year effective supply from that which is programmed it has been disregarded, albeit some narrative may be included in the case studies. Only where future programming is not set out in the HLA is the stated 5 year supply from the HLA utilised.
- HLAs, development plans and Scottish Government completion statistics don’t always work to the same period. They may run 1 April – 31 March or may relate to the calendar year. We have not sought to reconcile this issue so some minor discrepancies may exist between land requirement, completions and programmed completions. These would broadly iron themselves out over a plan period.
- Past completions and programmed completion data have been taken as read without interrogation.
- Housing Land Requirement (HLR) is based on SDPs for the city regions. Where an LDP figure differs from that set out in an SDP it is disregarded for the purpose of this exercise.
- The 5 year HLR is taken from the SDP or LDP and acknowledges variation in phases across the plan period.
- The HLR acknowledges under delivery from the beginning of the plan’s baseline, which is added to the HLR over time.
- Where the plan period expires within 5 years, the last year’s HLR is extrapolated forward.
- The 5 year HLR is taken from the SDP or LDP.
- The HLR across the entire plan period is divided by the number of years of the plan, with no allowance for phasing.
- Past performance including any under/over delivery is disregarded.
- Where the plan period expires within 5 years, the equalised annual HLR is extrapolated forward.
- The island authorities of Comhairle Nan Eilean Siar (Western Isles), Orkney and Shetland have been omitted due to availability of data.
- Fife has been excluded as the methodology employed doesn’t work on a Council-wide basis due to the area having two Strategic Development Plans and these being at such different stages in their cycles.

This is the second blog of the series and sets out Lichfields’ comparison of the two 5 year land requirement/supply calculations across the majority of Scotland. Further blogs over the coming week will include case studies of certain authorities and how they perform again each method.
