Which rules apply in Notting Hill?
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 Notting Hill 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.
- 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.
