The standard of workmanship including tidiness was exemplary, both the plumbing and electrical installation work was first class. The support from the installer during the pre award discussions and clarifications, and during and after the work was completed was also first class and again could not have been better. Whilst the work could probably have been done a little cheaper by others the quality and the end result was unmatchable in my opinion. The quality of the products installed was also the very best and the integration of Heat Pump, Solar panels, battery to give the optimum heat savings was excellent.
