We've been quoted for a baxi condensing boiler with 10y guarantee (also pressurised tank thingy, so not a combi). But an ideal has been fitted. Turns out plumber our builder used doesn't fit baxi boilers. We were told the boiler fitted was the same, with 10y guarantee and sent specs but the boiler in the spec is not what has been fitted (different model).
How would you handle this?
