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. Landlords in London (EC1A, EC1M, EC1N and EC1R) usually come to us with a council letter, a fire risk assessment or a house they have just bought. We price from whichever you have.

Which rules apply in London?
EPC and energy upgrades in London 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.
- A conversion can be a material change of use under the building regulations, so confirm with building control before work starts.
