"We have really noticed a big difference in the temperature of the house, rooms heat up much quicker and stay warm a lot longer, which is just what we wanted! Its a great result, and I think it made the difference between us staying here in Shetland or returning south. All of your staff were fantastic. Each and every one was a delight to have around the house, and were all very organised and tidy workers. I cant speak highly enough of your company and the work undertaken. We are absolutely delighted with everything you have done for us "
