I have used Andrew twice recently and have two positive reviews: (1) Many thanks to Andrew for his wonderful assistance; he was patient, tidy, really helpful and highly professional throughout the job. I feared it was going to be a lot more difficult than it turned out to be. After extensive testing, which Andrew undertook in a patient manner in cramped spaces the pressure issue was traced to an area under the concrete floor. I shall have no hesitation in requesting Andrew in the future, his technical knowledge was outstanding and we were very lucky to locate him as he put right previous work carried out by less competent qualified gas engineers. (2) Andrew attended on time, was through and tested the gas fire extensively. He took more trouble than previous heating engineers, checked outside flues and took numerous measurements. The engineer was tidy and left the site clean. I would recommend Andrew to anyone who wants a competent, experienced and friendly heating engineer, he knows his heating engineer skill set thoroughly'.
