Preparing for Winter: How to Stop Paying to Heat Your Walls

With energy costs still biting, most UK households are looking for ways to cut bills before winter sets in. But the most effective fix is one most people have never considered — and it’s hiding directly behind your radiators.

The Problem Nobody Talks About

If your radiators are on exterior walls, a significant portion of the heat they produce conducts straight through the brickwork and warms the outside air. You pay for every bit of it. Independent testing shows up to 45% of a radiator’s heat output can be lost this way.

The Fix: Radiator Reflector Panels

Heatkeeper Radiator Reflector Panels fit discreetly behind your radiators and reflect up to 95% of that wasted heat back into the room. Unlike kitchen foil DIY hacks, Heatkeeper’s flexible PVC saw-tooth profile creates permanent air pockets that insulate, reflect, and boost convection simultaneously — cutting heating bills by an average of 20%. No tools, no tradesperson, easy DIY fit.

Other Quick Wins Before Winter

Pair your panels with these no-cost steps: draught-proof gaps around doors and windows, bleed radiators with trapped air, and drop your thermostat by one degree — each small change compounds the savings.

Act Before the Cold Sets In

Search interest in energy-saving products spikes every October. Fitting Heatkeeper panels now means your home is already working efficiently when temperatures drop — not playing catch-up in January.
