Most installers and reviewers reckon that a boiler is good for about 10 - 12 years, so if you're getting significantly more than this you're doing well though the latest boilers will be more efficient. Also agree that Worcester-Bosch are best as they regularly top reliability charts (eg Which?). Our last boiler which was about 17 years old when we changed it in October 2024 never put a foot wrong though we did have it serviced annually and it was replaced with one of their latest models which is proving just as reliable. Note that if you have it installed by one of their approved installers then depending on which range it's from you get a warranty of up to 10 years.If your boiler is older than 12 years its a blessing in disguise .New boilers are a lot more efficient you be shocked on how much you will save in gas bills.
Combi boilers are a lot more unreliable due to the fact every thing like the expansion tank is squashed inside
best bolier Worcester Bosch
best for the price Pottern .
would also recommend Hive if you dont already have it .
Mrs GSV worked out that we've had it for almost 17 years - far longer than I'd have credited it. Efficiency of old one was over 89% and new one will be 94% - sounds like we shouldn't expect a massive saving, though the old one is (I would guess) highly unlikely to have been working as well as it did when new.If your boiler is older than 12 years its a blessing in disguise .New boilers are a lot more efficient you be shocked on how much you will save in gas bills.

Aren't they trying to phase out gas boilers in favour of electric ones?Mrs GSV worked out that we've had it for almost 17 years - far longer than I'd have credited it.

We had to get rid of the boiler that was in when the house was new because it started to sound like the house was being buzzed by a biplane every morning...
