Heating a converted attic is usually straightforward: in most homes we extend your existing central heating system up into the new room, typically with an extra radiator or two. In some cases underfloor heating is used instead, which keeps the walls clear and works well under the sloped ceilings. Your existing boiler and system size are checked to make sure they can carry the extra load comfortably.
Insulation is the more important part of the job, and it is not something to cut back on. A roof space is exposed on all sides, so it has to be insulated properly to meet Part L of the Building Regulations. This is done either as a warm-roof build-up or as insulation between and under the rafters, sealing the room within a continuous insulated envelope. Getting this right is what keeps the room warm in winter and, just as importantly, stops it overheating in summer. A poorly insulated attic is either cold or unbearably hot, so the specification matters.
- Heating: usually an extension of your existing central heating, an extra radiator or two, or underfloor in some cases.
- Insulation: warm-roof or between and under rafter insulation to satisfy Part L.
- Comfort: correct insulation keeps the room usable all year, not just in mild weather.
Good insulation also protects the finishes and reduces running costs over time, so it pays back on the everyday comfort of the room. You can read more on our attic insulation page, or book a free assessment and we will explain the build-up suited to your roof.
