It was very easy to make an online booking and again was easy to change the booking when the original one became inconvenient. The engineer notified me of his arrival time and arrived as he said. He was very professional and kept me informed throughout his visit. Best of all he fixed the problem with the washing machine by repairing the circuit board rather than taking the easy but expensive option of replacing it. I will certainly make use of Domex again if I need to have an appliance repaired.
