Which rules apply in Carshalton?
Sound insulation in Carshalton must satisfy national law for England, the council’s written HMO standards and, where walls, drainage or fire separation change, the building rules. In short:
- Where the building regulations apply to a conversion, Part E sound requirements can apply between rooms and floors.
- Building regulations cover structural changes, new partitions, ensuite drainage, fire-resisting construction and notifiable electrical work.
- A conversion can be a material change of use under the building regulations, so confirm with building control before work starts.
