Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, for what reason electric room heaters are considered less efficient than radiators powered by an oil boiler for the purposes of an Energy Performance Certificate, given that electric heaters can be powered by renewable energy.

Energy Performance Certificates (EPCs) use an Energy Efficiency Rating (EER) to score the energy performance of buildings based on their estimated running costs. Since energy costs can be a significant outlay, it is important that homeowners and occupiers are aware of the potential running costs of their building.

Given the higher cost of electricity relative to oil, the presence of an electric radiator may result in a low EER without added measures to reduce energy demand, such as insulation. The metrics on the EPC are kept under review as the Government develop policy to simultaneously tackle fuel poverty and decarbonise buildings.
