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 Willesden (NW10) 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 Willesden?
House to HMO conversion in Willesden 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:
- 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.
- National rules ask for an adequate number of bathrooms, WCs and basins and suitably located kitchens; numeric ratios are set by each council.
- 7 or more sharers is a sui generis large HMO and normally needs planning permission.
