I would like to thank both you (Gareth) and Dylan for promptly arranging to come out on both occasions and help us resolve the issue in a timely manner. On both times you were here for a good couple of hours at least, but you didn’t leave until the system was fixed. During the process you were both very respectful of our property and helpful in assisting me understand why these faults were being triggered and how you were approaching things. While I am hopeful we won’t need to call you over again any time soon, I am reassured that if the need should arise we would be in good hands.

Many thanks.
