Which rules apply in Wiltshire?
- 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.
Councils in England can add additional licensing and Article 4 directions on top of the national rules. Check the council’s website for the exact address before you buy or start work.
