Quick cure for the flue
Customer Service
Having discovered another central heating company had installed an incorrect flue extension to my Vaillant boiler, I urgently needed a competent local engineer to put matters right. Glowing reviews on Which Trusted Traders led me to call Complete Heating and Gas. By good fortune their company director Gary Cousins was working nearby and popped over within the hour to survey the job. I had a clear written quote and had accepted it and fixed a date for the work by that same evening. On the appointed date Gary turned up on time with the correct parts, did a thoroughly professional job and tidied up carefully. Admittedly this was a fairly simple job but I was impressed by Gary's quick response, professional knowledge, clear communications, friendly manner, and willingness to take on a small job and work in an outhouse on a freezing cold morning. Next time the need arises I'll be certain to give him a call.

Professional, friendly and tidy
Customer Service
Gary completed a service of our boiler which was replaced last year. Was very polite and tidy and covered the work expected. Arrived on time and provided a summary of the work completed.

Professional, efficient and tidy
Customer Service
Gary was very quick to visit my house, assess my broken boiler and advise the best replacement options. He provided a comprehensive and competitive quote and came a few days later to remove the old system and replace it with a new boiler. The new boiler was up and running the same day, radiators cleaned out, minor issues resolved at no additional cost and the system was fully tested before he left. Gary & Jo were professional, polite and incredibly tidy and neat. I would definitely recommend them.

A thoroughly professional and high quality service
Customer Service
Gary fitted a new boiler and sorted out complicated problems in my central heating service in a friendly and professional manner. He took exceptional trouble to solve the problems at a very fair price.

Highly recommended
Customer Service
Gary and his colleagues fitted a new combi boiler in my kitchen when my old one broke down. He arrived to do a quotation within an hour-and-a-half of first calling him, and he was able to schedule the boiler fitting within a few days of giving the quotation. He was very helpful in answering questions and talking through the different options, and was quick and professional in communicating with me. On the day of the fitting he turned up on time and the boiler was installed and working by mid-afternoon. The standard of work was high, and they left the kitchen clean and tidy. Highly recommended.

Professional, fast and reasonably priced
Customer Service
Having suffered from poor work from other plumbers in the past I can't praise Gary and his assistant highly enough. Punctual, obliging and fast they complated the installation of my boiler properly, left things spotless on completion - and charged less than the other trusted traders. First class.
Difficult Job Very Well Done
Customer Service
I cannot praise Gary Cousins & his team enough following our old back boiler being condemned in early December. His professionalism and work ethic are exceptional coupled with his attention to detail in leaving ones home as they found it. Having obtained four quotations theirs was the most competitive, although dubious at the timescale stated my concern was unfounded. The workmanship is first class involving the relocation of a new condensing boiler and ancillary pipework from one room into the kitchen. I have absolutely no hesitation in recommending Complete Heating and Gas.
Fitting of new combi boiler
Customer Service
Outstanding work beyond my expectations. From his free survey, Gary immediately gained my trust by recommending the most appropriate boiler, rather than the most expensive. In doing the actual job, Gary and his team demonstrated an excellent work ethic, turning up early and completing the job on time. They performed a very high standard of work, and made the extra effort to avoid mess- putting down floor & carpet protectors etc. The new boiler is working superbly and I look forward to having a local service who now knows my house and how its set up. Thoroughly recommended!
