Radiator Repair & Installation — Local Heating Engineers
Radiator repair and bleeding by an engineer
A radiator that stays cold at the top usually just needs bleeding, but one that's cold at the bottom, leaking, or never warms up points to a bigger issue worth fixing. BoilerFinder UK helps you find local engineers who repair, replace and install radiators.
Common radiator problems
- Cold at the top (trapped air — needs bleeding)
- Cold at the bottom (sludge build-up)
- Leaks around valves or joints
- A radiator that never heats up
- Uneven heating across the house (needs balancing)
What a radiator repair involves
Depending on the fault, an engineer may bleed the radiator, replace a faulty valve, fix a leak, balance the system so every room heats evenly, or fit a new radiator. Fixing these improves comfort and can lower your heating bills.
How much does radiator work cost?
Small jobs like bleeding or a valve replacement typically cost £80–£150. Supplying and fitting a new radiator usually costs £150–£300 depending on the size and type.

Frequently asked questions
Can I bleed a radiator myself? Yes — it's a simple job with a radiator key (see the video). If radiators are cold at the bottom, though, you'll likely need an engineer. Why is one radiator always cold? It may need balancing or the valve may be stuck — an engineer can sort this quickly.
