What is Room in Roof Insulation?
Room in roof insulation involves insulating the sloping ceilings, walls, and flat ceilings of attic rooms to prevent heat from escaping through the roof. It’s ideal for homes with converted lofts or rooms built directly into the roof space.
By creating a continuous thermal barrier, this type of insulation keeps your home warmer in winter, cooler in summer, and significantly reduces heating costs.
Under the ECO4 and GBIS schemes, qualifying homeowners and tenants can have room in roof insulation installed free of charge or with a subsidised grant, depending on eligibility
How Room in Roof Insulation Works
Room in roof insulation works by adding high-performance insulation boards or quilt between the sloping ceilings, walls, and flat areas of your attic room. This creates a continuous thermal barrier that keeps heat inside during winter and prevents it from entering in summer. By stopping warmth from escaping through the roof — one of the largest sources of heat loss in UK homes — you can make your entire property much more energy-efficient.
Once installed, the insulation helps maintain a consistent indoor temperature, meaning your heating system doesn’t need to work as hard. This leads to lower energy bills, improved comfort, and a warmer living space all year round.
Under the ECO4 and Great British Insulation Scheme (GBIS), eligible homeowners and tenants may qualify for free or heavily subsidised room in roof insulation, depending on property type and household circumstances.
