Community Infrastructure Levy – Household Developer Exemptions

Matthew Pennycook MP, Minister of State for Housing and Planning, treads a fine line in recent communication with the 164 Local Planning Authorities (LPAs) in England that have adopted Community Infrastructure Levy (CIL), aimed at addressing long-standing concerns around the operation of CIL exemptions for household developers.

Pennycook's letter sent last week (25 June 2026) advised that the Government remained committed to strengthening and improving the CIL regime (via the previously announced CIL consultation expected in July), with over half of local planning authorities (in England) now charging CIL.  It is a significant letter because it formally recognises the unfair outcomes that have arisen where otherwise eligible applicants have lost exemptions due to procedural errors.

A central theme of the letter is the acknowledgement of the gap between policy intent and real-world outcomes for too many householders.

Whilst the regulations were designed to provide clarity and certainty, the government accepts that they have, in practice, led to a wide variation in outcomes depending on individual awareness, access to advice and the way local authorities communicate requirements.

Looking forward, the government commits to consulting on reforms to the CIL regulations.  These changes are intended to make the system “clearer and more proportionate,” with a particular focus on ensuring that householders who meet the substantive criteria for exemption are not disproportionally penalised purely for procedural missteps.

For existing and historic cases, the letter places strong emphasis on discretion by LPAs.  Although councils remain under a duty to collect CIL, they are reminded that they have flexibility in how they enforce payment.  Authorities are encouraged to consider what is reasonable and proportionate in each case, including the timing and severity of enforcement action.

The government also raises concerns about the use of aggressive enforcement measures, noting that actions such as threats of forced sale or criminal proceedings have caused serious hardship.  It makes clear that such escalation is not mandated by the regulations and should be assessed carefully in light of broader legal obligations and individual circumstances.

A further key point that Pennycook mentions is the explicit confirmation that councils may make ex-gratia compensation payments in exceptional cases.  This provides a potential mechanism for redress where a householder would have qualified for an exemption but failed to secure it due to procedural error and now faces significant financial hardship.

The letter has implications for a wide range of stakeholders, including LPAs, advisers and household developers currently facing or disputing CIL liabilities.

In the short term, authorities are expected to review their guidance and communication to ensure that applicants clearly understand exemption requirements. 

E³ Consulting recognise that in the twelve years since self-build exemptions were introduced, many (not all) LPAs have become far better at signposting the issues and highlighting the need from timely action to avoid significant and unnecessary CIL payments.

LPAs are encouraged to adopt a more measured and case-by-case approach to enforcement, particularly in situations involving technical breaches rather than deliberate non-compliance.  Whilst maintaining the need to collect CIL due...

For affected householders, the guidance strengthens the basis for challenging disproportionate enforcement action and for seeking alternative resolutions, including negotiated payment arrangements or, in exceptional cases, compensation.

Looking ahead, the proposed consultation on regulatory reform is likely to result in amendments to the CIL regime aimed at reducing reliance on strict procedural compliance.  While any changes will apply prospectively, they signal a broader policy shift towards a more balanced and equitable system.

Overall, although the legal framework remains unchanged for now, the letter sets a clear expectation that councils should exercise their existing powers with greater flexibility and sensitivity, particularly where rigid application of the rules has produced 'somewhat unjust' outcomes at odds with the original intent of the exemption regime.
