Which rules apply in Wembley?
The rules below are the England-wide position for this kind of work. Councils add their own standards and schemes on top, so we always check the address in Wembley before we price.
- 7 or more sharers is a sui generis large HMO and normally needs planning permission.
- A conversion can be a material change of use under the building regulations, so confirm with building control before work starts.
- The Fire Safety Order 2005 applies to the common parts of HMOs, enforced by the fire and rescue authority.
- Floor area under a ceiling lower than 1.5 m does not count towards the room size, and many councils set larger sizes.
