Which rules apply in Hounslow?
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 Hounslow before we price.
- Licences last up to 5 years and carry conditions on gas and electrical safety, alarms, room sizes and waste.
- Floor area under a ceiling lower than 1.5 m does not count towards the room size, and many councils set larger sizes.
- Council standards often step up at 5 and 6 sharers, for example a separate WC at 5 and a second bathroom from 6.
- 7 or more sharers is a sui generis large HMO and normally needs planning permission.
