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 Northolt (HA2, UB4, UB5 and UB6) 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.

- Under the Renters’ Rights Act, civil penalties reach £40,000 for offences such as running an unlicensed HMO.
- Licensed HMOs must meet national minimum bedroom sizes: 6.51 m² for one person aged 10 or over, 10.22 m² for two, and 4.64 m² for a child under 10.
