Only the vertical pipe that comes down from upstairs. All the pipes under the radiator are cold. Although when I turned all other rads off and turned heating up to 30 the pipe in was v hot and the pipe out was luke warm.

One of the pipes to the rad are nearly blocked or a rad valve is nearly closed off. Could be either of the pipes.
Just needs someone to disconnect each valve from rad and run into a bucket carefully or into a hose to see which is blocked and if the flushing clears it.
You could have a bit of crud in the horizontal part of pipes below rad.
Very very easy for a plumber to check it.
Thank you. Blooming ‘eck I feel like enrolling myself on a ‘Radiator Maintenance for Idiots’ evening course!
Speak to Which?, see what they say. I dont normaly disagree with Ian, but whatcan be the harm. Apart from more delay.
Failing that, I would sort out yur complaint in a logical manner and email to HUG, but find an email address of somene that matters. Tell them that you refuse to pay the TRV bill, and that you will source a local RGI. If they try to subsequently enforce the bill, this correspondence will be of value to you. And make sure you get a written itemised bill from the guy who sorts it.
Just realised as writing: They have changed the TRV? But that locksheild that you posted is not new? Tou said they quoted £174 for TRV AND LS?

I think the OP got a different engineer in to do the TRV perhaps?

@Lissybits, can you remove the white cap covering the rad valve (the one you posted a photo of) and upload a photo, and also one of TRV?
It was a different engineer but still a HUG engineer.
Rip off price for what should have also been a free call out to solve the problem.
How long did it take for the engineer to replace the TRV?
I probably could. But tomorrow evening now.
Well actually he soon realised that the TRV wasn’t the cause of the cold radiator but changed it anyway as it was stuck down. Then put some inhibitor in somewhere and did some other things! He was here about 3.5 hours in the end.
I'd be whipping that rad off, running a hose through it outside. Wet vac on the two valves whilst open. Connect the valves together and running the CH. If that failed, I'd stick my flushing machine onto the valves and rock back and forth the flow with a little acid for 10 mins or so.
At what point did he realise the TRV was not the issue. Given that he said it was stuck down?
Many years ago, I had a similar problem. Had changed a radiator , IIRC. At the end of the job a dining room rad was cold. I had not cleaned the system, but the owner insisted the rad was previously okay.
I did all the normal stuff, and had left the other rads off for an extended period. For whatever reason, I had decided it was an airlock. I booked a morning to spend some time and get it resolved, but it was several days later.
Arrived on the appointed day, and the customer came to the door a little perplexed. It had started working THAT morning. (Assuming they’re were truthful). Presumably air had moved and cleared. Never heard from them again so all was good. But what if I had gone the day before?
Weird stuff sometimes occurs.
Hi everyone,
Just an update on my cold lounge radiator (which only got hot if I turned 2 other rads off). F
Finally had the time/money to call a local heating engineer out. He diagnosed the problem immediately over the phone! Guess what? It wasn't a blocked pipe - the radiators simply needed balancing!!
He did it all in an hour and charged me £60.
As oppose to HUG's wrong diagnosis of a BLOCKED PIPE that they quoted £450 to repair!!!!!
Imagine if I'd gone ahead with that and borrowed the money too? Disgraceful!
Anyway, though some of you might be interested to hear what the problem was.
All nice and toasty now!

Thank you for letting us know , too many just ask for advice get it and move on
Hope you've kept this Guy's details for next time you need a Plumber! HUG should hold their heads in shame, absolute cowboys.
