Matthew Pennycook, the Minister of State for Housing and Planning, has extended the deadline for submitting legacy-system local plans for examination to 31 March 2027. The letter, published by the Ministry of Housing, Communities and Local Government on 23 October 2026, applies in England and covers local planning authorities as well as minerals and waste authorities. (gov.uk) The change is tightly defined. GOV.UK states that the amended deadline applies where an authority has reached Regulation 19 consultation by 31 December 2026 and is not subject to formal local plan intervention. (gov.uk)
The extension adjusts a transition point that had been fixed earlier in 2026. Government and Planning Inspectorate guidance says the new plan-making system began in March 2026, with a dual-running period in which the legacy route remained available only for plans submitted by 31 December 2026. (gov.uk) In his letter, Pennycook said the original deadline had accelerated progress, with 56 plans reaching pre-submission consultation during 2026. The department is therefore keeping the older route open for authorities already at an advanced stage, rather than requiring them to start again under the new arrangements because of short administrative delays. (gov.uk)
The threshold matters because Regulation 19 is the final public consultation stage before a plan is submitted for examination under the legacy system. Planning Inspectorate guidance defines the publication date in legacy monitoring as the point when the authority carries out that final consultation before submission. (gov.uk) For policy teams and elected members, that places the extension at the very end of the process rather than the beginning. Authorities still need to complete committee sign-off, document finalisation and other governance steps before submission, and the minister’s letter recognises that some were at risk of missing the December deadline by narrow margins. (gov.uk)
The legal basis is specific. Pennycook said he was using the Secretary of State’s powers under paragraphs 4(5) and 5(5) of Schedule 1 to the Levelling-up and Regeneration Act 2023 (Commencement No. 11 and Saving and Transitional Provisions) Regulations 2026, which permit a later submission date to be directed for specified legacy local plan and minerals and waste plan documents. (gov.uk) The automatic extension is not universal. The letter states that plans already covered by a specific direction on submission dates are not included, and that any authority in that position would need to seek an amendment individually. GOV.UK also summarises the policy as excluding authorities subject to formal local plan intervention. (gov.uk)
The letter is operational as well as procedural. Authorities that will no longer submit by 31 December 2026 are asked to send an updated Local Development Scheme to the department by the end of November, setting out their revised submission date. In practice, that means councils must revise their published plan timetable rather than relying on the extension alone. (gov.uk) Ministers have also made clear that the extra time should not slow authorities that are already ready to move. Where Regulation 19 pre-submission consultation has already been completed, submission should proceed as planned and as soon as possible. (gov.uk)
For planning officers, councillors, applicants and residents following site allocations, the revised timetable is now clear. The main dates are completion of final Regulation 19 consultation by 31 December 2026, an updated Local Development Scheme by the end of November where needed, and submission by 31 March 2027 for plans using the extension. (gov.uk) The wider policy signal is that this is a short administrative easement, not a reopening of the transition. The minister says there should be no expectation of any further extension beyond the end of March and describes this as the last opportunity to secure submission in the legacy system. For authorities that miss it, plan-making would, by implication, need to continue through the post-March 2026 framework. The final sentence is an inference from the government’s stated transition timetable. (gov.uk)
