England is moving most planning appeals onto an expedited written track from 1 April 2026. The Statutory Instrument, signed on 10 February and laid on 12 February, amends the 2009 Written Representations Regulations and the 2015 Development Management Procedure Order. According to legislation.gov.uk, the change makes written determinations the default for the majority of appeals brought under section 78(1) of the Town and Country Planning Act 1990.

The Government has rebadged Part 1 of the 2009 Regulations as “Expedited Written Representations”. Where the Secretary of State decides a case is suitable for this route, it will be decided on paperwork without a hearing or inquiry. A safety valve remains: if an appeal proves unsuitable, it can be transferred to the fuller written procedure in Part 2 under regulation 9 and section 319A of the 1990 Act.

Scope matters here. From April, section 78(1) appeals-including those linked to advertisement control via section 220-default to the expedited track. By contrast, section 78(2) appeals and advertisement discontinuance cases sit on the non‑expedited written route in Part 2. The instrument extends to England and Wales but applies to appeals in England only.

The Development Management Procedure Order 2015 is also updated. Articles 15 and 37 are adjusted and a new Schedule standardises what must be lodged with an appeal under section 78(1). In practical terms, appellants should expect more consistent document lists across authorities and fewer chances to top‑up evidence later.

There is a saving provision for pipeline schemes. If a householder or minor commercial appeal relates to an application made before 1 April 2026, the previous DMPO requirements continue to apply to that appeal. That avoids moving the goalposts mid‑process for those already in train.

For SMEs and regional housebuilders, the headline is speed with strings attached. Faster written decisions can trim holding costs and bring forward cash receipts, but the trade‑off is tighter early deadlines and less scope to finesse arguments once the appeal clock starts. Winning now leans more on the initial statement of case than on oral advocacy later.

That shifts where project budgets land. Expect a bit less on hearing preparation and counsel time, and more up‑front on technical reports-transport, design, drainage, ecology-and on clean, well‑cross‑referenced evidence packs. Finance directors should bring consultancy spend forward in cashflow models and allow for quicker document turnarounds.

Consider a typical SME scheme refused on highway capacity. Under the expedited route, the appellant’s transport rebuttal, junction modelling notes and any design tweaks must be locked into the opening submission. There is limited room for late evidence, so weaknesses left in the background become risks to delivery and to exit timelines.

Local planning authorities and the Planning Inspectorate gain clearer document expectations and less scheduling pressure for hearings. If the process beds in, SME applicants could see more predictable timetables. If backlogs persist, the written default still helps by removing the diary friction that often drags on inquiries.

When might you ask for a transfer to the fuller route? Complex heritage harm, technical viability disputes or cases where credibility turns on cross‑examination may justify it. The bar is not low: appellants should frame the request tightly against section 319A, showing why written exchanges cannot fairly test the issues.

Key dates anchor planning strategies. The regulations were made on 10 February 2026, laid on 12 February 2026, and come into force on 1 April 2026. Teams should align committee cycles, appeal risk assessments and funding milestones to those fixed points, especially for schemes eyeing an April submission.

What we’re watching next is guidance and performance data from the Planning Inspectorate once cases start under the new rules. If decision times shorten and documentation becomes more uniform, the planning risk premium in SME appraisals could fall. We’ll track the early cohorts and report on outcomes as the regime beds in.
