Questions about large HMO conversions (7+ sharers) in Northolt
Do you handle building control?
Yes. The building work in a large HMO conversion (partitions, fire separation, drainage, electrics) needs to meet the building regulations, and the conversion can also count as a material change of use. We confirm the route with building control, coordinate inspections and give you the completion paperwork.
Which postcodes in Northolt do you work in?
All of them, including HA2, UB4, UB5 and UB6, and the surrounding parts of Greater London.
Does a shared house in Northolt need an HMO licence?
In England, a mandatory licence is needed for 5 or more people from 2 or more households. Smaller HMOs can need a licence where the council runs additional licensing, which is common in towns with many shared houses. Check the council’s website for the address.
