There are many measures designed to improve the energy efficiency of a property, varying in cost.
Insulation: A lot of heat is lost from a home through poor insulation.
Wall insulation: Properties built since 1920 will probably have cavity walls (a gap between two walls) so insulation can be installed within the cavities. Homes built after 1990 will probably have cavity wall insulation already. If a property is over 100 years old, it will probably have solid walls and require a solid wall insulation system.
Roof and loft insulation: Most roofs can be insulated, providing a cost-effective way to improve energy efficiency. A minimum of 270mm of loft insulation is recommended.
Floor insulation: The ground floor of a property can lose up to 15% of a property’s heat so benefits from insulation. Floorboards can be insulated using rigid boards, spray foam insulation or mineral wool while solid floors can have a layer of rigid insulation laid on top.
Windows and doors: Double glazing makes windows more energy efficient, reducing drafts, energy bills and providing noise insulation. Options include double glazing, triple glazing and secondary glazing.
Pipe insulation: Hot water tanks and pipes lose a lot of heat if not insulated. Fit a cylinder jacket and insulate accessible hot water pipes to minimise heat loss.
Draught-proofing: Off-the-shelf draught proofing systems can be bought in any DIY store to prevent heat loss and draughts around doors and windows.
Lighting: Fit low energy LED light bulbs - these use around 90% less energy.
Smart thermostats: A smart thermostat allows a home’s heating system to be controlled more efficiently, minimising energy use.
Upgrade the boiler: If a boiler is old, consider investing in a new model to improve efficiency and performance.
It could take some time to implement the required energy-saving measures to ensure a property meets the required EPC C rating so we recommend making a plan now to ensure you meet the government’s deadline of April 2025.
