Thanks for everyone's assistance, new expansion vessel fitted and all is well.

sorry for delay in updating. Have checked the expansion vessel and it's full of water! New has been delivered and will fit once it stops peeing it down. Only problem with external oil boilers, the only breakdown when it's raining or snowing.

@Exedon, thanks for the pointer. Hadn't even been checking pressures during the day, was suck in a mental loop that I had a leak. Did a PRV leak off test, and yes the PRV is opening. Will test the tank when the system is cold, and probably just replace as maintenance. Thanks

@iammcd - refilled system to 1.4 bar at 07:10 and at 08:10 was reading 2.4 bar.

Has anyone known a Grant 26 combi (external) to leak internally into the flame chamber? For the approx four weeks, every morning the boiler has lost all it's pressure. I refill the system to 1.2 bar, and it kicks back in, and works fine - rads toasty warm and hot water is hot! This may last two...
