Questions about large HMO conversions (7+ sharers) in Northamptonshire
What fire alarm does a large HMO need?
The fire risk assessment and the council decide; alarm grades come from guidance, not statute. For larger HMOs, council guides and the NI fire service guide commonly point to a Grade A panel system covering escape routes and rooms. We fit to the specification set, and give you the commissioning certificate.
Does a seven-bed HMO need planning permission?
In England, normally yes: seven or more unrelated sharers is a sui generis use outside class C4. Wales and Northern Ireland require permission for new HMOs anyway, and in Scotland more than five residents falls outside the houses class. Councils also apply concentration policies, so we check the address first.
