Fair point - I'm going off my own personal statistics which has a sample size of 1 (i.e. just me!). My experience has been good.So easy to fool the public...no boilers are British...those that claim to be are assembling parts from overseas. Baxi actually import and rebadge some of their Dutch boilers for the UK lineup.
It's a lot of luck with boilers...Baxi have produced some of the worst boilers in history...some of their current range is ok but there's still some models you should avoid at all costs.
TBH the British thing isn't a deal breaker for me - all the big companies are global nowadays - who owns Jaguar now, is that still British?!? god knows
If you go down to a parts level hardly any of the finished article is solely manufactured in just one country - most parts probably come from the far east. We hardly manufacture anything.. but we do still put all the bits together
