Radiator cold at the bottom in East London? Here's what usually causes it.
A radiator that’s cold at the top usually needs bleeding to release trapped air, while one that’s cold at the bottom often points to a build-up of sludge in the system. We diagnose why your radiators aren’t heating properly — air, sludge, a stuck valve or a circulation problem — and fix the underlying cause rather than just the symptom, so the warmth comes back and stays.

Radiator leaking onto your floor? Here's why you shouldn't leave it.
A leaking radiator or valve should be dealt with quickly — even a slow drip can stain floors, damage carpets and cause rust. We trace the source of the leak, whether it’s a valve, a union joint or the radiator itself, and repair or replace the affected part so your system holds pressure and stays dry.

Why are some rooms warm and others freezing — does your system need balancing?
If some rooms are warm while others stay cold, your system likely needs balancing so hot water is distributed evenly to every radiator. Where radiators are full of sludge and cold patches keep returning, a power flush clears the build-up and restores circulation. We assess whether balancing alone will do the job, or whether a flush is the better long-term fix.

Frequently Asked Questions
Why is my radiator cold at the bottom but warm at the top?
That's the classic sign of sludge build-up inside the radiator restricting flow. Bleeding won't fix it — it usually needs flushing or, in bad cases, the radiator removing and cleaning. We'll diagnose it and advise the best fix.
Can you add a radiator to a cold room?
Yes. We can add radiators to rooms that are hard to heat, provided your boiler and system can support the extra load. We'll check the system can cope and recommend the right size radiator for the room.
Do I need to replace all my radiators at once?
No. Radiators can be replaced individually as needed. If several are old and inefficient you may choose to upgrade them together, but there's no requirement to — we'll give you honest advice on what's worth doing.
My radiator is leaking — is it urgent?
Don't leave it. Even a small leak can damage flooring and let air into the system, causing further cold spots. Turn off the valve if you can and call us — we'll get the leak stopped and the part repaired or replaced.
Are your engineers qualified to work on my heating?
Yes. All our work is carried out by Gas Safe registered engineers, and any work involving the boiler or gas side of your system is fully certified.
How much does radiator work cost in East London?
