Answer 7 quick questions about your home. No score needed — we work it out from what you actually have.
Step 1 of 7
When was your home built?
The era of construction tells us a lot about wall construction, insulation standards, and what systems were installed.
What are your walls like?
Walls account for up to 35% of heat loss. Not sure? Solid walls are typically 23cm+ thick; cavity walls have a gap you can sometimes feel at door frames.
What's in your loft?
Loft insulation is one of the most cost-effective upgrades. The recommended depth is 270mm (about 10 inches). No loft access? Choose 'flat roof or no loft'.
What windows do you have?
Look at the edge of the glass — double glazing has a visible gap (usually filled with a spacer bar). Triple glazing has two gaps.
What's your main heating system?
Boiler age matters too — a condensing boiler fitted after 2005 has an efficiency of 90%+. Older boilers can be as low as 60%. Not sure? Check the model name and look it up.
Any renewable energy?
Solar panels (PV) and solar thermal are the most common. These can push your rating up by a full band or more, especially if the system is large enough.
What lighting do you have?
Easy to check — LED bulbs are usually labelled. Halogen spotlights (warm, often in ceilings) count as low-efficiency. Strip lights in kitchens are often fluorescent.
