Blocked central heating pipe

If it is a blockage in a pipe it could be either the flow or return to rad.
The fact that the flow pipe gets very hot is normal in a nearly blocked circuit, but can still be the flow pipe blocked.
Good chance the pipes could just be simply flushed out from each rad valve of that rad.
The pipe blocking is perhaps something that is just a risk of happening in an old dirty system, so I wouldn’t entirely blame the boiler installers (if they correctly did a chemical flush).
But I would have thought the company would have came back FOC to try to sort it.
Out of interest, - did your last engineer try to run the valves into a hose to check flow?

Never heard of HUG, but did a quick google and saw no issues. However, they are part of Which? trusted traders scheme. Did yiu know this? You may wish to look int how they can help. It would be interesting for us to know how that goes.

The valve was already fully anti clockwise and can’t go any further. Now I have turned the heating down to 20 and turned the radiators back on, the radiator in question is luke warm at the top and cold at the bottom.Chemical Flush
This may be a bit daft, but weird things get missed. Try to remove the valve cap from the other valve. You may need a small screwdriver, or if no screw visible on top it pulls off. Once off, use an adjustable spanner and turn the spindle fully ANTI clockwise. Count the number f 1/2 turns until it stops. Try heating. Report back
When you say valve you mean this?

What exactly was fitted? Just a boiler changeover, or further works. There are obligations on aninstaller to comply with part L, did they do any pipework alterations?
Stupid things do occur. Many years ago, I gave a guy I knew a chance to work with me. He wasn't a plumber, but wanted to work. Hr told me that he had helped his plumber dad in the past, so had some basic skills. When we had finished, one radiator was very hard to get working and on a small house it shouldnt be difficult. Anyway, it turned out that he had nailed the CENTRE of a board (any pro knows that you nail towards the edge of the board and run pipes down the middle) . The nail was presenting a massive resistance to the flow.
So, as per Terry's query, what was taken out and what went in? Could a pipe be nailed. Did they not test the heating before leaving?

Yes! I did lots of research before I spent over £2000. But I hadn’t thought of contacting Which.
So an old combi Baxi boiler came out (not sure of model but I do know it was smaller in litre capacity) and a Worcester Bosch 30i went in. Just a straight change, nothing else altered.
Now I have turned heating back down to 20 and put all the other radiators back on, the lounge rad is stone cold again. Yes they did test heating before leaving but whacked up the heating and it worked. Now I can’t actually remember if it did work at normal temp but if it did it was literally only for a few days..

Contacting which ???? you would be better contacting a distant relative at seance
Was a magnetic filter fitted near the boiler?

If I was there,I would be turning off valves, disconnect and run water into a container, just to see flow. Quick swap of valves and try again. Just to eliminate valves from issue. I would bet against sludge causing this, TBH. But then, if I was installer, I would have returned to sort out, not to sell another job.
Trouble is, a lot of installers seem to work on shoestrings so have nothing in reserve.

Are either of the pipes hot to it? Did the TRV get changed? Have you tried to removed the head?
Should I just give up on HUG and find a local plumber? I haven’t yet paid HUG for the unnecessary trv etc that was changed on last visit...
