that's exactly my issue, the kit is cheap and installation only a day at most, but knowing the savings you're going to make the MCS registered installers load the install costs. My 14 panel system kit cost is £3500, the quotes are £7500. With FIT that's about 7y ROI, but just saving on usage without FIT with £500 for the sparky to install gives me a 2.5y ROI.
