An HMO loft conversion adds one or two letting rooms, often with an ensuite, in the roof space. In Greenwich, a town of about 31,000 people in Greater London, the work is planned around the HMO rules for England and the council’s written HMO standards. Greenwich 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 Greenwich?
Here is what usually applies to a Greenwich job of this kind. It is general information rather than legal advice, and the council’s written HMO standards have the final detail.
- 7 or more sharers is a sui generis large HMO and normally needs planning permission.
- A conversion can be a material change of use under the building regulations, so confirm with building control before work starts.
- 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.
- 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.
