| lily, i'd agree with everthing 4d says. Worcesters are a v. good combi manufacturer as are vaillant (whch i fit on a daily baisis). the quotes the gas board give are on average a f. massive p. take.
what area do you live in?
one last thing, when you get somone round, ask to see their corgi card. if they're registerd they wont mind showing you. if they start making excuses and look shifty, show them the door. theyre probably unregistered and should not touch gas.
let me know how you get on
