Radiator Repairs & ReplacementsWarm Again.
Cold radiators, leaking valves, noisy pipes - our heating engineers diagnose and fix central heating problems fast. We also carry out power flushes to restore full heating efficiency.
What We Do
Our experienced engineers deliver reliable, professional service every time.
Cold Radiator Diagnosis
Full diagnosis of cold or partially cold radiators - we identify whether the issue is a blocked radiator, valve or system-wide sludge.
Radiator Valve Replacement
Replacement of failed or stuck manual and thermostatic radiator valves (TRVs). New lockshield valves fitted as required.
New Radiator Installation
Supply and fit of standard double panel radiators, connected to existing pipework and balanced to the system.
Power Flushing
High-pressure power flush of the whole central heating system using specialist equipment and chemical cleaners to remove black sludge.
TRV (Thermostatic Valve) Replacement
Upgrade from manual to thermostatic valves on all radiators for better temperature control and efficiency.
Magnetic System Filter Fitting
Supply and fit of a magnetic system filter (Magnaclean or equivalent) to capture future sludge and protect the boiler.

Common Radiator Problems
Radiators that aren't heating properly are usually suffering from one of a few well-known issues, most of which are quick to diagnose and fix.
Cold Spots (Trapped Air)
A radiator that's cold at the top but warm lower down usually has trapped air, which bleeding will normally fix.
Cold at the Bottom (Sludge)
Cold at the bottom but warm at the top points to sludge and debris settling in the radiator, often needing a power flush.
Leaking Valves
Leaks around the valve are usually down to a worn seal or a loose connection, both straightforward to repair.
Uneven Heating Across Rooms
If some rooms heat well and others don't, the system may need balancing so heat is distributed evenly.
Noisy Radiators
Banging or gurgling noises are often caused by trapped air, sludge build-up, or a pump running at the wrong speed.
Radiator Not Heating at All
A completely cold radiator is often a closed or stuck valve, though it can also indicate a blockage in the system.
Frequently Asked Questions
Simple Maintenance That Prevents Problems
Bleeding radiators every few months, especially at the start of the heating season, clears trapped air before it causes cold spots. It's a five-minute job that makes a real difference to how evenly your home heats.
A power flush every few years clears the sludge and debris that naturally build up in a central heating system, restoring efficiency and reducing strain on your boiler and pump.
If problems keep coming back despite regular maintenance, it's often a sign of a deeper issue in the system that's worth having properly diagnosed.
