Alfonzo was exactly what we needed from a heating engineer. Knowledgable and patient at the same time, he spent an incredible amount of time explaining everything to us and making sure we got exactly what we needed. He was very accommodating of the schedule of other building work in the house, and arrived bang on time to do the job. The work was done to a really high standard at a very reasonable price and we are already planning to have him back to replace more radiators upstairs. Would highly recommend him.
