Central heating
Swapping a tired radiator or adding one to a cold room is one of the simplest ways to make a home more comfortable. Getting the size and position right is what makes the difference.
Repairs make sense for a sticking valve or a one-off weep. Replacement makes more sense when:
A radiator's heat output needs to suit the room: its size, how many outside walls and windows it has, and how well it is insulated. Older solid-wall houses and rooms with big windows need more output than a well-insulated bedroom of the same size. Going for a radiator because it looks right on the wall is how people end up with rooms that never warm.
Chris works out the output each room needs and suggests sizes that fit the space, including double panels or taller designs where wall space is tight.
The simplest job is a new radiator with the same pipe centres as the old one, so it connects straight onto the existing pipes. If the new one is a different width, or you want it on another wall, the pipework has to be extended or rerouted, which takes longer, especially under solid floors.
New radiators usually go in with new valves at the same time, so the old valves are not left as the weak point. Our page on radiator valve replacement covers valves on their own.
We do not publish radiator prices, because they depend on the job. The things that change it are the size and style of the radiator, whether the pipe centres match, whether pipework has to move, how easy the floor is to get under, and whether the system needs draining down and cleaning. Designer and column radiators cost more than standard panels. Chris gives you a clear figure after looking.
A radiator that is cold or leaking is not always a radiator that needs replacing. Our guides to radiators not heating up and a radiator leaking can help you work out whether a smaller fix will do. Radiators are one part of our wider central heating work.

Common questions
Clear answers before you arrange a visit.
It depends on the radiator, whether the pipes need moving and how much draining and refilling is needed. Chris will give you a figure after seeing the room.
Yes, with a heat-resistant radiator paint, applied when the radiator is cold. Avoid painting over the bleed valve and the valve heads.
Bleed it, check both valves are open and check the boiler pressure. If it is still cold or leaking, it may need a new valve or a replacement radiator.
A metal panel filled with hot water from the boiler, which gives off heat into the room. Most homes have steel panel radiators connected by pipes to the heating system.
