Which? Trusted Trader — independently vetted & approvedFrom balancing and powerflushing to replacing tired radiators and fitting heated towel rails — we'll get every room warm again.
Based in Brentford TW8 — fast response across West London.
Cold spots at the bottom of a radiator usually mean sludge; cold at the top means air. We use thermal imaging to see exactly what's happening inside your system — no guesswork — then fix it with bleeding, balancing, a powerflush or replacement as needed.
Upgrading to modern radiators or a heated towel rail? We supply and fit all styles and sizes, matched correctly to each room's heat requirement.
Cold at the top usually means trapped air — a bleed sorts it. Cold at the bottom points to sludge and a system that needs flushing. Some rads hot, others cold, means the system needs balancing. Add leaks from valves or pinholes and gurgling noises, and you've covered most of what we're called out for.
We diagnose before we act: sometimes it's a five-minute balance, sometimes a flush, sometimes a valve or a whole radiator that's corroded through. You'll always get the honest, least-disruptive fix first.
Beyond repairs we fit thermostatic radiator valves for better control and lower bills, swap tired rads for efficient modern panels, install heated towel rails, and add or relocate radiators when you're reconfiguring a room. Tidy work, tested and guaranteed.
Gas leak, burst pipe or no heating? We're available around the clock.
A radiator that's cold at the bottom but warm at the top usually contains sludge — a build-up of rust and debris. A powerflush clears the system and restores full heat output.
Banging or kettling noises are often caused by trapped air, limescale or sludge, or a system that needs rebalancing. We diagnose the cause with thermal imaging and fix it at the source.
Yes — supply and fit, in chrome, anthracite and designer finishes, correctly sized for your bathroom.
That's sludge settling in the bottom of the radiator, and it means the system would benefit from a powerflush. Our guide explains it in full.
Yes — we add, relocate and upgrade radiators and fit heated towel rails, tidily and tested.
