Baxi is pricey, very pricey, i'd plump for a cheaper boiler with good customer service instead. They don't answer the phone, when they do its duff info, and then transfer you, meaning they cut you off, now thats just to register your boiler, So BEWARE, don't buy a Baxi boiler or even worse Boiler warranty repair, as if they don't answer the phone, they won't answer it for a repair to get it repaired! waited 20 mins to be cut off when they couldn't send me info on email, the digital way of confirmation and having things in black and white, they don't want you to have that. PS reply time is actually zero, but i couldn't choose that. They sure reply quick selling something though
