A house to HMO conversion turns a single-family home into a house in multiple occupation: a shared home for unrelated people with private bedrooms and shared kitchen or bathroom space. Landlords in Watford (WD1, WD17, WD18 and WD19) usually come to us with a council letter, a fire risk assessment or a house they have just bought. We price from whichever you have.

Which rules apply in Watford?
Here is what usually applies to a Watford job of this kind. It is general information rather than legal advice, and the council’s written HMO standards have the final detail.
- 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.
