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. Portsmouth is 15 miles south-east of Southampton. 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. Portsmouth has a university population, so many shared houses are let to students on yearly tenancies, and summer is the main window for works.
