Thanks again - spot on. I've actually just had the BG man out to look at it. No water coming out of the vessel valve, and there was some pressure in there. He repressurised it and retried the boiler and same problem (water pressure going to 3 bar and prv triggering). He tried again, but this...

Thanks guys. I've checked the expansion overflow pipe, and when I top up the pressure and leave the boiler cold, there is no water released at 1bar, but when the ch is on and the pressure rises to 3bar, the water is released. Hence it seems the prv is working correctly (set to 3 bar), and so it...

Think Ive realised I've been monitoring the wrong pipe. The plastic one is for Condensate, right? I'll check the copper one for PRV. Also, having had some time to search this site properly, looks like there is a lot of posts relating to Baxi Combi's having to have their expansion vessel...
