Faulty Boiler - Speedy fix
Posted 03 January
Sergei was quick to contact me and his comms were spot on throughout. He was considerate (coming with covers for his shoes), knowledgeable and clear when explaining the problem with my boiler. He had it fixed and serviced in no time and provided a follow-up call the following day to make sure all was still okay. Very impressed and happy to recommend .
