Yeah but as I said client don't want to see it Simon , I can do it with a Intergas boiler possibly a Worcester I've done it before with the old CDI Classic not sure about the newer range ??

Baxi or viessmann heat only

Just seal it like normal. If they're going to leak, they'll leak. If not now, maybe in 6 months time.

Heat only boiler and seal the system but only pressurise to 0.5?

Went with a Intergas Hre 40 kw system boiler coupled with a OSO delta 300 litre unvented cylinder 3 zone heating and hot water , upgrade on living room rads and all valves. 😉👍
