I've been quoted £1000 to supply and fit a gas combi boiler, i'll be doing the pipework myself for the radiators. Its a 32kw boiler and we live in an old two up two down terrace house on the outskirts of nottingham.
its a new boiler, i can't remember the manufacturer now, been bought out by a bigger manufacturer so being sold off cheap. Doesn't need to be ultra reliable as we are planning on moving next year.
