Which rules apply in Carshalton?
EPC and energy upgrades 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:
- Rented homes must currently meet at least EPC E, with a £3,500 spending cap. The government plans EPC C by October 2030, subject to legislation.
- Councils can fine up to £7,000 where a Category 1 hazard is not removed when it reasonably could have been.
- 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.
