Very effective for cutting heat loss!
I tested it on four radiators in an older Manchester flat. One radiator was on a thin exterior wall. Before installation, the temperature difference was 7.5°C (14.5°C vs 22°C). After installation, it dropped to 2.5°C (15°C vs 17.5°C). You can feel the improvement quickly.
Setup is simple. The adhesive patches hold well, cope with heat and cold, and don’t mark the wall. Cut, stick, done.

alright, I’ll admit it i didn’t place it perfectly 😅 but honestly I don’t care I just wanted to cut down the energy bill
my last bill was lower than the previous year (even though this winter is sooo much colder), and I’ve noticed the radiator kicks in less often since I installed it. I’ve set it to automatic mode so it only turns on when the room drops below 20°C and now it hardly needs to
It no longer picks up the cold from the wall, which makes the radiator way more efficient. It’s kind of crazy… such a simple idea, but really clever in how it works and its conception

I used HeatMate behind all the radiators on my external walls to deal with cold rooms, and the results were genuinely impressive. The installation was quick, the material is light and easy to cut, and it fits even in tight spots.
Across every room, I saw a steady rise of about 1.5 to 2°C, especially in the colder areas. The reflective foil really does send the heat back into the room instead of letting it escape.
It’s slim, durable, and once in place you don’t notice it at all.
Simple, effective, and great value. HeatMate has made a clear difference.

Used it behind my radiators, directly on the wall, to stop the heat escaping into the wall and push it upwards instead. Very easy to cut and install with double-sided tape. Took just a few minutes. Amazing

Very easy to work with. Excellent product, easy to cut and handle. I wrapped it around my water heater to retain the heat, and also used it to insulate the hot water pipes running through my unheated garage. It helps keep the water warm as it travels to the upper floor. Perfect product!! highly recommended! 👍

to insulate my front door. I checked with a thermal thermometer: the aluminium door was 2°C, and with the insulation it went up to 12°C 👌. When I need to go out, I just roll it to the side behind the curtain, easy and invisible 😁

Every time the radiator runs, a chunk of the warmth slips straight into the wall.
You’re paying to heat… whatever is behind your house.
And when the cold sets in, that waste turns into higher bills week after week.
HeatMate keeps the warmth inside – where you actually need it.
✅ Stops heat loss the moment it’s installed
✅ Cuts thermal waste without any DIY
✅ Works with any radiator
✔️ High-grade aluminium layer – reflects heat back into the room
✔️ No radiator removal – installs in minutes
✔️ Flexible cut-to-fit design – adjusts to any size
✔️ Ultra-thin profile – slides behind all radiators
✔️ Heat-resistant and long-lasting
✔️ Wipe-clean surface – stays effective all year
Picture this:
You turn on the radiator.
The room warms faster.
You haven’t touched the thermostat.
Nothing leaks into the wall.
Just steady, comfortable warmth that stays put.
Now picture the opposite:
Cold walls.
A radiator running longer.
Heat fading away.
Thermostat creeping up.
Bills rising with it.
✨ “Picked up between 1.5 and 2°C in the coldest rooms. Simple install, instant change.”
