HMO energy upgrades improve the energy performance certificate (EPC) rating and cut running costs: loft and wall insulation, heating and controls, glazing, ventilation and lighting. Southampton is 43 miles south-west of Reading. We price EPC and energy upgrades there against England’s HMO rules and the council’s written HMO standards, so work is planned to the standard an inspection looks for. Southampton has a university population, so many shared houses are let to students on yearly tenancies, and summer is the main window for works.

Which rules apply in Southampton?
EPC and energy upgrades in Southampton 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.
