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 Northampton, a place of roughly 250,000 people, the work is planned around the HMO rules for England and the council’s written HMO standards. With students as well as working sharers renting in Northampton, we plan bigger jobs for the gap between academic-year tenancies where we can.
