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.

Pricing

Clear, fixed prices with no hidden fees or call-out charges.

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

Radiator repairs start from £80. Replacing a radiator including a new thermostatic valve typically costs £150 to £350 depending on size and access.
This usually means there is trapped air in the radiator. Bleeding the radiator releases the air and restores heat circulation. If bleeding does not fix it, sludge build-up may require a power flush.
A power flush is a deep clean of your central heating system using specialist equipment to remove sludge, rust, and debris. It typically costs £300 to £600 for an average home and significantly improves boiler efficiency.
A standard radiator replacement takes 1 to 2 hours. Adding a new radiator in a room that did not previously have one may take 3 to 4 hours including pipework.
Yes. We can add radiators to existing central heating systems, including installation of new pipework and thermostatic radiator valves.

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.

Cold spots and noisy pipes usually mean sludge build-up - a power flush can restore full efficiency.
