your boiler is a band D only band A has a 3 yr warranty.
A band is the most economical and efficient boiler yours is D which is the least. in other terms rubbish. if you want a decent boiler you want a worcester or a valliant. which are about £700. yours is worth about £450.
as for your builder telling you, surely you have the paperwork on the boiler so why didn't you read it with regards to the warranty ?
as regards to it breaking down, thats just sods law it happens alot in the real world when the guarentee has just run out.
law states they have to give a min 1yr guarentee if you want extended you have to pay wether it a boiler or washing/machine etc.
so it comes down to you taking the builders word for it
dear mistake.............
