An HMO loft conversion adds one or two letting rooms, often with an ensuite, in the roof space. Landlords in Northampton (NN1, NN2 and NN5) 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. Northampton has a university population, so many shared houses are let to students on yearly tenancies, and summer is the main window for works.

Which rules apply in Northampton?
The rules below are the England-wide position for this kind of work. Councils add their own standards and schemes on top, so we always check the address in Northampton before we price.
- 7 or more sharers is a sui generis large HMO and normally needs planning permission.
- Building regulations cover structural changes, new partitions, ensuite drainage, fire-resisting construction and notifiable electrical work.
- Fire precautions follow a risk assessment; the LACORS Housing – Fire Safety guide (2008) is guidance, not law, but many councils base their standards on it.
