Mounting a TV Above a Radiator

It can be safe — but it depends on the clearance between the top of the radiator and the bottom of the TV. The minimum recommended distance is 10–15cm for a standard UK panel radiator. Below this, the heat output from the radiator can damage the TV over time, particularly older LCD panels. Modern TVs are more heat-tolerant, but excessive heat will shorten component life. We assess the clearance on every job.

A common starting point is 10cm between the top of the radiator and the bottom of the TV screen, with 15–20cm preferred for high-output radiators or smaller rooms where heat accumulates. The right clearance depends on the radiator output and the TV manufacturer's temperature limits — a heat deflector shelf can help redirect heat forward, but suitability is confirmed on the day.

A heat deflector (or radiator shelf) is a shelf fitted above the radiator that redirects rising heat forward and away from the wall — rather than rising straight up toward the TV. It is a commonly used solution when clearance is borderline; whether it brings clearance within the TV manufacturer's safe limits depends on the specific radiator output and the TV. We can supply and fit a heat deflector as part of the installation.

A TV wall-mounted above a radiator does block some of the heat rising directly upward, which can slightly reduce the radiator's efficiency. The heat deflector shelf mitigates this by directing heat forward into the room rather than upward. In most cases, the effect is minor.

Yes — cables running from the TV down to sockets below will pass close to or behind the radiator. We plan the cable route to avoid heat exposure — either routing cables to the side of the radiator rather than directly behind it, or using heat-rated trunking if behind-radiator routing is required.

In many cases, yes — but it depends on the TV size and weight, the wall type, and the radiator's heat output. Larger TVs create more of a heat shield effect, so for 65"+ above high-output radiators we strongly recommend a heat deflector shelf and confirm the clearance falls within the TV manufacturer's temperature limits. We assess the radiator output, clearance distance, and room size on the day before recommending a final position.

TV mounting above a radiator starts from £100. Most jobs use our Standard tier (from £150); we leave a safe gap above the radiator and use a tilt bracket so heat doesn't track up the back of the TV. See /pricing.
