Flat Roof Insulation
Proper insulation of flat roofs reduces energy loss and improves thermal comfort.
Learn more →Room in Roof insulation involves insulating the sloping ceiling, vertical walls (cheeks), and flat ceiling of a converted loft space. Unlike standard loft insulation, this requires specialist installation to maintain the usable room while dramatically improving thermal performance.
The same crews, the same specification and the same paperwork, whether it is your house or every home on a housing provider’s programme.
A free survey, an itemised quote and a straight answer, including when the job is not worth doing. Then our own crew, and a certificate at the end.
We deliver this measure as a package for funded retrofit programmes, on our own or as a subcontractor to your principal contractor, with the assessment and coordination done by our own people.
“Energy Giants played a pivotal role in over 100 installations for Next Energy, Internal Wall Insulation, Room in Roof and Flat Roof Insulation. Their commitment to excellence and quality workmanship contributed significantly to the success of our projects.”
Room in roof work is fiddly, inside the home and easy to do badly, which is why programmes ask for installers who have done it at volume. Ours have, and our retrofit assessment and coordination are done in house under PAS 2035, the same way we run the Aspire Housing whole house programme.
A properly insulated loft room adds significant value and appeal to your property.
Stay warm in winter and cool in summer with consistent temperature control throughout the seasons.
Dramatically cut your heating costs by preventing heat from escaping through the roof structure.
Transform an uncomfortable attic room into a fully usable living space all year round.
We assess your converted loft space, including slopes, cheeks, and flat ceiling areas.
If needed, we assess whether radiator pipe extensions are required before insulation work begins.
Insulation fitted to slopes, cheeks, and flat ceiling for complete thermal coverage.
All insulated areas are plasterboarded and finished for a clean, professional look.
A full quality inspection and certification is completed before final sign off.
Every room in roof insulation installation is backed by our own guarantee. This provides independent assurance that your insulation has been installed to the highest standards and will perform as expected.

We insulate three key areas: the sloping ceiling (rafters), the vertical walls known as cheeks, and the flat ceiling at the top. This creates a complete thermal envelope around the room.
Yes. A properly insulated and finished loft room can add up to 15% to your property value by creating additional usable living space with year round comfort.
Room in roof insulation typically takes 2 to 3 days to complete, depending on the size and complexity of your loft space. This includes insulation, plasterboarding, and finishing.
All room in roof installations come with our own guarantee, providing independent assurance that the work has been carried out to the highest standards.
Yes. Room in roof insulation is one of the measures we have delivered at volume, including over a hundred installs for Next Energy alongside internal wall and flat roof work. Our retrofit assessment and coordination are done in house. See our case studies or the sub contracting page.
Yes, and that is the point. The dormer cheeks and the short stud walls behind the eaves are where most converted rooms lose their heat, and they are the parts a standard loft insulation job leaves alone. We treat the slopes, the cheeks, the stud walls and the residual loft voids as one envelope.
Funding changes often, so ask us for the current position. As of September 2026 the Warm Homes: Local Grant, run through councils, funds insulation for eligible lower income households, and social landlords have the Warm Homes: Social Housing Fund. We deliver under these programmes for councils and landlords, and we will tell a homeowner honestly whether they are likely to qualify.
