There are only 1,000 half-price packs available, and when we've featured this deal in the past it's been extremely popular, so it's likely the packs will go quickly – it's strictly one half-price pack per person.

What's a radiator reflector?

These sheets are designed to be attached behind radiators, particularly those that back onto exterior walls, to reflect heat back into the room. This maximises your heating and could ultimately lower your energy bills.

The packs includes the sheets, clips and adhesive strips. If needed, you can cut the sheets to fit more radiators (depending on size). Radflek says its sheets reflect 95% of wasted heat energy back into your room. Its efficacy has been independently tested and verified by the British Board of Agrément and the Building Research Establishment.
