An HMO loft conversion adds one or two letting rooms, often with an ensuite, in the roof space. Landlords in Croydon (CR0, CR7 and SE25) 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.

Which rules apply in Croydon?
Here is what usually applies to a Croydon job of this kind. It is general information rather than legal advice, and the council’s written HMO standards have the final detail.
- 3–6 unrelated sharers is use class C4; changing from a family house is usually permitted development unless an Article 4 direction applies.
- Building regulations cover structural changes, new partitions, ensuite drainage, fire-resisting construction and notifiable electrical work.
- Smoke alarms on every storey with living accommodation and CO alarms by fixed combustion appliances (other than gas cookers) are required by law.
- Floor area under a ceiling lower than 1.5 m does not count towards the room size, and many councils set larger sizes.
