Thanks Shaun.
Don't know where I'd be without your help/advise.
Much appreciated mate.
One more question/s
Had burner pressure reading on max setting ( with clunk and banging) and a reading of 12mbars
Would that be the clunk and banging
MIs say it's 14mbars
The plate heat exchanger priced at £288 inc.
Removed CP12 and had explained the reason for constant build up of pressure.
Still can't work out why the pressure would still gradually up whilst tap rail isolator is fully off though!!!!
I've added the picture

Did you test the bp after 10+ mins ? As I'm sure there's something in the manual about it must be after x amount
Isolate the cold into the boiler and run a hot tap
If system pressure drops there's a pass between dhw and heating so new hx or boiler
Clunking could be a few things old pump not pushing the water away fast enough or hx dirty from sludge etc

Left them my number expecting to get an immediate response.
They've returned and ALL the way back home from Holland and said ...
Said .. said..
Sorry.
WTH
we GLAD to have them present whilst explaing the buildin up and the cause whilst doing a gas rate and bp
Yes had run the boiler for around ten mins on full prior to the bp.
Listsening to clunk and bang and staring who I the face lol..
Left premises and no way going back for any further assistances.
Was actually fumed over not contacting me in any way in regards to their noisy banging appliance.
Yes had turns it off after leaving and explain ed I'm going to be busy and ALL the way up to Christmas
Sure they got a message

Just noticed the flue bodging
Had to go back left my wrench was right on top of the boiler
Looked at the flu..
Well there are not to any current standards.
This would have been one to add ..
The appliance was a 28iKW
MIs say a 14mar burner pressure or near to
Had a burner pres of 2mbars below MIs 14

Flue is correct, I would want to see what the duct tape was there for but I think it's just to seal the outer flue
Before you said the burner pressure was 12 and now 2 which is it ?

Just a good old decent service and replacement of the ex vessel and you will be good to go and you will be fine
Good luck and remember no thinking about work 😀
Just skim read this so may have missed something
The pressure rise will probably be a pinholed main heat ex (between mains cold and heating side) and the banging could be the prv chattering due to overpressure
Have changed a couple of older Worcester twin pipe heat exs and they aren't cheap
edit
by twin pipe, I mean separate waterways for heating and hot water (it;s actually 4 pipes) doh

I said heat ex straight off mate. But I get the impression he doesn’t want Any part in it? As he says there is a load wrong with it.
