In short: 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. We carry this out across Powys, priced against the HMO rules for Wales and the council’s own standards.

Which rules apply in Powys?
- Rented homes must meet at least EPC E. Whether the planned EPC C standard will apply in Wales has not yet been confirmed.
- Councils assess hazards, including damp and mould, under the HHSRS, alongside the fitness for human habitation rules for occupation contracts.
- Building regulations cover structural work, partitions, drainage, fire-resisting construction and electrics; confirm with building control whether the conversion is a material change of use.
Welsh councils set their own HMO standards and may run additional licensing. In Wales, changing a house to a C4 HMO always needs planning permission, so check planning first.
