Questions

How many office-to-residential planning applications are there in the UK?

Councils have received 26,725 since January 2016, 1,544 of them in the 12 months to September 2026. Their share peaked in the 12 months to December 2016.

Which councils receive the most office-to-residential applications?

Birmingham, Leeds and Barnet have received the most since 2016.

Do you need planning permission to turn an office into flats?

In England, often not. Under Class MA, a building in use class E for 2 years can become homes with the council's prior approval, decided within 56 days. Listed buildings, national parks and national landscapes are excluded. Wales and Scotland have no such right.

Why did office conversion applications fall after 2021?

Class O closed to new applications after 31 July 2021, and the count fell from 2,974 in 2021 to 1,664 in 2022. Class MA replaced it, but most Class MA applications say only Class E (the use class covering shops, cafes, offices, gyms and similar town-centre uses) to homes, so this count leaves them out.
