Hi all, firstly I hope this is being posted in the correct forum? i'm really hoping to get some valuable advice from you knowledgeable folk. I have a 1 bedroom open plan house, upstairs bedroom and bathroom and downstairs living room and kitchen. I have had a quote from a friend of a friend to fit a new combi boiler etc. I have had the old system removed, along with the old hot water tank and the airing cupboard, and all the old pipe work. There are only 4 radiators in my house which I have had fitted onto the walls but not yet plumbed in. I have Been quoted £600 pounds to do the work plus obviously the cost of the boiler and the necessary extras to go with it. Somewhere in the region of £1700 all in which to me seems rather a lot considering all he has to do is put in the new boiler and connect it up to the rads. I have left the boiler and other parts to be purchased to him and he has gone for a boiler which is a main 24, whatever that is. I thank you in advance for any replies.
