that seems on par with what i have found. i have reduced my gas bill by about two thirds by replacing my boiler and going to town on insulating my house. this is the advice i give everyone these days. I would love to think i can progress into solar, but to be honest, and as mentioned elsewhere in the forum, it seems to be the big corporate companies who seem to be milking it, with little room for independants. i attended the installer road show which was as expected, very positive about the industry, but, i have found the reality of the truth a little hard to swallow. i had thought about doing solar thermal as an add on to what we currently do with domestic gas, but fear it will be hundreds of pounds down the drain. I dont even want to go on to the MCS system, which seems biased yet again to larger companies who have the financial muscle to make this process work.
