A radiator is a simple object and it reports its own faults quite clearly, as long as you pay attention to where it is cold rather than just that it is cold.

Top, bottom or one end each point to a different cause.
A stuck valve pin is a small job often mistaken for a dead radiator.
An undersized radiator is swapped for one that suits the room.
Shifting a radiator along a wall is usually smaller than people expect.
Cold at the top is air. It rises to the highest point in the radiator and sits there, and bleeding it releases it. If it comes back within weeks, air is getting in, which is a different and more interesting problem.
Cold at the bottom is sludge. Magnetite settles where the water moves slowest, which is the bottom of the panel, and bleeding does nothing at all for it. One radiator like that is a removal and a flush off the wall. Several, and it is a system question.
Cold all over, with hot pipes at the valves, is the valve. Either a thermostatic head whose pin has stuck down, which is extremely common after a summer of not moving, or a lockshield closed by somebody decorating. The pin test is simple: pull the head off and press the pin.
Radiator Repair is priced after the job has been seen, anywhere in the areas we cover. Send the postcode and a few lines about what it is doing when you contact us, and the answer comes back in writing.
Stuck thermostatic pins, failed heads, weeping glands and seized lockshields account for a good share of what gets reported as a broken radiator. Most are replaceable with the system still full by freezing the pipe either side, which means no draining and no afternoon without heating.
The temptation is to measure the old radiator and buy that size. The old radiator may well have been wrong, and modern panels put out different heat per metre from the ones they replace, so a straight swap on dimensions can quietly reduce output by a third. The output needed comes from the room, and the replacement is chosen to deliver it at the flow temperature the system actually runs at. Tail positions and pipe centres then decide how much pipework alteration is involved.
Along the same wall is usually straightforward. To a different wall means new pipework, and whether that is easy depends entirely on what is under the floor and which way the joists run. A joist running parallel to the new route is a good day; running across it is a lifted floor and joists notched to the span tables, which is a structural matter and not something to improvise.
Everything we have written on this job, newest first, is in the radiator repair resources.
Which room, where on the radiator it stays cold, and whether the others are fine. A photo of its valves helps.
