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. In Derry, a town of around 85,000 people, the work is planned around the HMO rules for Northern Ireland and the NI HMO standards and licence conditions. Derry has a university population, so many shared houses are let to students on yearly tenancies, and summer is the main window for works.
