An HMO loft conversion adds one or two letting rooms, often with an ensuite, in the roof space. Preston is 27 miles north-east of Liverpool. We price loft conversions for extra rooms there against England’s HMO rules and the council’s written HMO standards, so work is planned to the standard an inspection looks for. With students as well as working sharers renting in Preston, we plan bigger jobs for the gap between academic-year tenancies where we can.

Which rules apply in Preston?
Here is what usually applies to a Preston 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.
- 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.
- Floor area under a ceiling lower than 1.5 m does not count towards the room size, and many councils set larger sizes.
