    In order to remove a radiator presumably I would need some form of end caps to secure over the ends of the two copper pipes which protrude from the floor after having removed the radiator.

    Would anyone happen to know the name of such ends caps so I can search for them to purchase a pair?

    Thanks.

    Cant you leave the radiator valves on.....save you some grief!
    I have capped them (15mm) with compression stop ends - cap only - but it depends on the olive position to be a success.

    If it is semi permanent, you’ll want Stop Ends, compression will go directly on the pipe where the valves were.

    If it is permanent and you are doing this under the floor you will want Stop Ends in soldered form (You can use push fit, but i wouldn’t do it in my home).

    If it is for decoration then it will depend on the valves you have. 1/2” cap on a rad tail is the best method.

    As for sizes, depends on the size of your pipe, most are 15mm - Some are 10mm and some are 8mm.

    I need to remove the radiator to decorate behind it, then I'll have a plumber come in to install a new radiator in a slightly different location within the room.

    If I leave the radiator valves on do I require some form of stops after I've removed the radiator? Are the compression stop ends used only if the valves are removed?

    If you have lockshield and wheel-heads that isolate up ok, then you can take the rad off and decorate to your hearts content without anything.

    If you have TRVs then I’d advise a decorators cap (These would have come with the original TRV, but if you can identify the TRV, flea bay is a good guess if you don’t have them - many will fit many different types, but this is experience to identify) and replace the TRV head with the decorators cap so it don’t open up on its own accord.

    Of course, if you want to be double sure, nick the rad tails from the radiator and x2 1/2” caps with some PTFE does a grand job with no surprises. Also good for valves that don’t “quite” shut properly - just remember to tell the plumber that they don’t quite shut as well, so he knows to expect a bit of pressure build up once he pops the caps off.

    It's not thermostatic.

    They're the most basic radiator ends, I'm not sure if that's classed as lockshield. It's one turnable wheel on one end.

    So do you mean if the radiator is removed and I leave the valves in place on the ends of the copper pipes I don't need to cap these?

    That is correct, only thing is if they are ancient they could drip slightly but u won't know until u take the rad off
