Faster Appeals, One in Three Allowed: How the Refusal Calculus Changed in 2026

For years the honest advice after a marginal refusal was often to walk, because an appeal meant the best part of a year and an uncertain result. The 2026 numbers change that advice. Here is what moved, and how it reshapes the decision after a refusal.

The Planning Inspectorate's statistical release of 23 April 2026 records a median appeal decision time of 18 weeks, down from 21. In the twelve months to March 2026 there were 19,617 appeal decisions, 32 per cent of section 78 appeals were allowed, and 479 inspectors were in post. A shorter queue and a roughly one-in-three success rate are a different environment from the one most acquisition models still assume.

Time is the hidden cost of an appeal. At close to a year, the holding cost, the option cost and the opportunity cost of tying up a site often outweighed a one-in-three chance of success. At 18 weeks, that arithmetic shifts. Testing a contestable refusal becomes a live commercial option rather than a last resort, particularly where the land can be held under option rather than owned outright.

The merits still decide the case. A refusal grounded in a genuine and evidenced policy conflict does not become weaker because the queue is shorter. What a faster system rewards is the quality of the original submission: a clean policy case, constraints addressed on their merits, and a refusal reason that does not survive scrutiny. The developers who benefit from quicker appeals are the ones whose applications were defensible in the first place.

After a refusal, three questions decide go, fix or walk. Is the refusal reason a genuine policy conflict or a contestable judgement. Does the same authority's recent appeal record suggest inspectors have taken a different view. And is the evidence base strong enough to carry an appeal without a year of drift. We read refusals against appeal outcomes in the same authority, so that the decision to appeal, amend or move on is made on evidence rather than instinct.

The wider policy picture that sits behind this is covered in planning reform in 2026.
