Many town and city centres now have more office space than they need, while demand for housing remains high. Converting offices into homes has become a familiar response, and the planning system has been shaped to encourage it. The national planning policy behind these conversions changed again in August 2026, however. Anyone involved in a conversion, whether as a property owner, a business tenant or a buyer, should understand where they now stand.
This article covers the position in England. Wales has its own planning rules, and the permitted development right described below does not apply there.
How the permitted development route works?
Most office conversions in England rely on a permitted development right known as Class MA. It has been available since August 2021. It allows a building in Use Class E to become residential without a full planning application. Class E is a broad category covering offices, shops, cafés, gyms, clinics and nurseries.
