Which rules apply in Ruislip?
House to HMO conversion in Ruislip must satisfy national law for England, the council’s written HMO standards and, where walls, drainage or fire separation change, the building rules. In short:
- Under the Renters’ Rights Act, civil penalties reach £40,000 for offences such as running an unlicensed HMO.
- 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.

Questions about house to HMO conversion in Ruislip
Do I need planning permission to turn a house into an HMO?
It depends on the nation, the council and the number of sharers. In England, three to six unrelated sharers is use class C4, and moving from a family house is usually permitted development unless the council has an Article 4 direction; seven or more normally needs permission. In Wales a change to an HMO always needs permission, in Northern Ireland all new HMOs need it, and in Scotland council policy decides. We check the address before drawings start.
