When I installed a Fernox Boiler Buddy filter for my brother, I made sure I fitted those Pegler pump valves. Boiler Buddies fit between two gate valves the same as a pump would.
I knew I would be relying on those valves regularly to isolate so that the BB can be removed for cleaning. They turn...
I'm not sure I would use silicone grease on the seal for these. May encourage the seal to slip out of place as tightened. I always make sure that the Perspex bowl and the area where the rubber seal is are spotlessly clean. A stray fragment of Siliphos ball/crystal could cause it not to seal at...

But then, I don't suppose it would have had a chance of winning the Turner Prize like the one in the op.
Why doesn't the op say what the boiler make and model is, then others on here can say whether it contains asbestos? Very unlikely for a boiler under 20 years old. I think there is overkill of the rule book.
Then the boiler can be removed from the wall by the op if he wishes. Zero danger if the...
What's wrong with the old bracket? If it's just split, get someone local with a welder to repair it. Won't notice when it's behind the rad.
Nobody fixes anything any more!

If you can, fit an external vessel. 30 quid for the vessel from Toolstation, plus a bit of pipe and...
