Radiator Replacement

What radiator replacement covers

Replacing a radiator is more than swapping a panel on the wall. The service is focused on safe fitting, correct sizing, and making sure the heating circuit runs as it should.

• Removal of the existing radiator and isolation of pipework
• Advice on suitable radiator type, size, and heat output for the room
• Installation of the new radiator, brackets, and connections
• Replacement or upgrade of valves (including TRVs, if required)
• Bleeding, refilling, and pressure checks
• Leak testing and basic system checks after fitting
• Neat finishing and responsible disposal of the old unit

When radiator replacement is the right choice

This service is a good fit if a radiator is corroded, leaking, slow to heat, or has persistent cold spots that do not improve after bleeding. It also suits refurbishments where you want a different style or size, or where a room layout has changed. Landlords and small commercial sites often choose replacement to improve reliability and reduce call-outs.

How the work is carried out

You will usually start with checks on the existing setup, pipe positions, and how the radiator is currently performing. The system is then isolated and drained as needed, the old radiator removed, and the new unit mounted and connected. Finally, the system is refilled, air is released, and the radiator and valves are tested so heat-up is even and there are no leaks.

Aftercare and getting the best performance

After installation, you will be advised on bleeding, pressure, and how to use the valves effectively. If there are signs of sludge or poor circulation, you may be recommended further steps such as balancing, inhibitor dosing, or system cleaning to help the new radiator perform properly. If you notice any changes in pressure or a damp patch, it should be checked promptly to prevent damage.
