England speeds up planning decisions for home extensions from 31 October
Homeowners in England who want to extend their homes or convert a loft should now get a faster answer. From Saturday 31 October 2026, straightforward planning applications are decided by expert planning officers instead of waiting for a slot at a council planning committee. The change comes under a new National Scheme of Delegation, announced by the Ministry of Housing, Communities and Local Government on 30 October.
The rules cover everyday cases such as house extensions, loft conversions and conservatories, as well as small businesses improving their premises. These householder applications make up nearly 70% of all planning applications in England each year, according to the government. Councillors will now focus on larger, more complex developments.
The government is also backing the change with more staff and new technology. It says 420 planners have joined councils through government-backed programmes, beating its 2024 manifesto promise of 300. An AI tool called PlanAssist, built with Google DeepMind, Google Cloud and Faculty, pulls together applications, local policies and site details in one place for officers to review. In early trials in Camden, Barnet and Dorset, the government says it cut time on key tasks by 58% and halved routine processing times from eight weeks to four. It is now being tested at 15 councils for 12 months, with the aim of offering it to every council in England by the end of 2027. Officers remain responsible for every decision, and councils will not be forced to use it.
Why it matters
For families, the change is about certainty. An extension or loft conversion is often a big financial decision, and waiting months for a committee date has been one of the longest delays in the system. Removing that wait should mean quicker answers, although it does not guarantee permission: an application can still be refused, and officers must still check it against local planning rules. The change applies in England only.
What happens next
Councils in England now have to apply the new national scheme when deciding which cases go to committee. The 12-month PlanAssist trial will show whether the time savings seen in the first three councils hold up at a larger scale. The government has not said how the change affects applications already waiting, so anyone in that position should check with their council.
