R (Stephen Luck) v Bracknell Forest Borough Council [2025] EWHC 2984 (Admin)
Luck CIL self-build is an important Planning Court judgment on self-build exemption, commencement and a later disqualifying event where the exempted development was never completed.
The court dismissed the challenge to Bracknell Forest’s CIL demand. Once the exempted permission had been commenced, liability had arisen under the statutory scheme, and a later event which meant the original development could no longer be completed was capable of triggering loss of the exemption even though it occurred outside the ordinary clawback period.

What Luck decided
The case concerned Pine Acres in Ascot. A 2017 permission authorised a dwelling and annexe and the developer obtained a self-build CIL exemption worth about £334,000.
The permission was commenced, but the main house was never completed. A later planning permission for two different houses was then implemented and the site was sold, making completion of the original exempted scheme impossible.
Bracknell Forest issued CIL liability and demand notices. Mrs Justice Lieven dismissed the judicial review challenge.
CIL liability is fixed by commencement
The judgment emphasises the central role of commencement in the CIL regime. Once chargeable development begins, the levy position is engaged and the person benefiting from relief or exemption must continue to satisfy the statutory conditions which preserve it.
The fact that the original scheme was later abandoned did not mean that the liability which had arisen at commencement simply disappeared.
See Planning Geek’s guide to CIL commencement for the practical significance of that date.
A disqualifying event did not have to occur within the ordinary clawback period
The claimant argued that the self-build exemption could only be lost if the relevant disqualifying event occurred during the statutory clawback period.
The court rejected that construction. The particular disqualifying event relied upon here was the failure to complete the exempted development in circumstances where a later inconsistent permission had been implemented and the original scheme could no longer be completed.
The Regulations did not impose the temporal restriction contended for. The different statutory events and consequences had to be read according to their own wording.
An inconsistent later permission can matter
The later two-house permission was not merely another consent sitting unused on the planning register. It was implemented.
That implementation meant the exempted 2017 development could no longer be completed as authorised. The factual and legal change was therefore capable of constituting the event which brought the exemption consequences into play.
The council had no free-standing discretion to waive the levy
The claimant relied on the apparent harshness of being charged CIL on a development which would never be completed.
The court held that the collecting authority could not create an extra-statutory discretion to waive liability simply because the outcome appeared unfair. CIL is a detailed statutory code and any relief, transfer, abatement or discretionary relief has to come from powers actually contained in that regime.
Planning Geek’s guide to CIL exemptions and reliefs explains the available statutory routes.
Potential double recovery did not justify rewriting the Regulations
The claimant also relied on the possibility that levy could be charged in connection with more than one planning permission affecting the same land.
The court rejected the invitation to solve that concern by giving the Regulations a meaning their wording would not bear. The CIL regime already contains mechanisms dealing with changes, transfers and abatements in defined circumstances.
Why Luck matters
The case is especially important where a self-builder changes course after starting an exempted scheme. A later permission, sale or redesign should not be treated as a planning-only issue: the CIL consequences of the already commenced permission need to be checked before the new scheme is implemented.
It is another example of why commencement is often the point at which CIL risk becomes difficult to unwind.
