Gary supplied and fitted a new Worcester Boiler. He gave professional expert advice on the initial visit, explained everything fully including costs, and delivered a truly first class service! I couldn’t recommend him enough!

Gary Cousins fitted the perfect boiler for the house, excellent and transparent quotes, more professional than large companies. He is the best boiler Engineer I’ve met, head and shoulders above the rest. If you want the best service and best quote choose Complete Plumbing. Unlike my previous experiences Gary and his team were very respectful, professional and a pleasure to have in the house.

Customer in Esher

Gary was very good at communicating what needed to happen and then actually carrying out the work – including resolving a problem with the boiler itself, which required getting someone else in to help – thoroughly recommended.

Customer in Kingston upon Thames

All round excellent, gave us tips on things we could do to improve other work, we will definitely be using him again!

Customer in Esher

We are very glad that we chose Gary to install the boiler for us. He provided a premium service for us for a very competitive price. He completed all work to a great quality and maintained our house nice and tidy without any of us being at home. We will contact Gary for any future work and would recommend him to everyone.

Gary and his assistant Tom where a pleasure to work with. His price was very competitive. He was on time and carried out the work efficiently, politely and left the premises the way he found it. His professional approach and advice was welcoming. We entrusted him with our house keys and he called us when he was done. I called him for advice on the boiler he installed and he was more than willing to advise me. A big thumbs up to Complete Heating and Plumbing.

Customer in Worcester Park

If you’re like me and get 3-4 quotes, then save your time and see Gary first. Gary was highly skilled, friendly and works twice as fast as the competition, which means he works fewer days and can therefore offer better rates. I asked him to supply and fit a boiler that needed millimetre precision as a kitchen unit was going around it afterwards. I also asked for decorative exposed pipework which is not easy. Gary went above and beyond, even laying a new wooden floor when the carpenter couldn’t turn up. Gary also came back to check on things and even helped my neighbour. Will 100% use again.

Gary and his colleague were excellent and Gary is a very good communicator and kept us informed over a period of days while he had the difficult job of sourcing a not easy to obtain flue. It is rare to find people who communicate so well and we appreciated this. The job was very well done and at a competitive price. We are very grateful that Gary and his colleague were able to fix our boiler. Many thanks.

Customer in Esher

Could not recommend Complete Heating and Gas more highly. Gary was unusually personable in the plumbing trade and what was most impressive was that he also made himself available when things beyond his control from subcontractors did not come up to par and he put them right quickly. Nothing is too much trouble with Gary. His commitment to us being completely satisfied was outstanding. We would use him again. Wish there were more tradesmen like him out there.

Customer in Surbiton

If I could score higher than a 10 for ALL of the answers I most certainly would! Gary Cousins has to be one of the most honest, reliable tradespersons I have ever had the pleasure to have come across, I can’t recommend him highly enough. He certainly is worth his weight in gold.

Customer in Surbiton

Well, what can I say, right from the very first phone call to the job being completed Gary provided a top class service. I had about 5 or 6 quotes to have a new boiler. I read through many Checkatrade reviews and Complete was one of the companies I contacted. Gary was very quick with a response, he came round had a good look at the job and provided a written quote very quickly. His pricing is very fair and his quotes are very clear. I asked Gary to do the work for me and from start to finish he was brilliant. An extremely likeable and honest chap, very hard working and a great job done. Superb!

Customer in Surbiton

Really impressed with Gary. Responded very quickly when originally contacted and we were given a very clear and competitive quote for the proposed work. On the day of installation, they worked very hard, and the job was completed by mid-afternoon, very pleased with the work done and very happy to recommend.

Customer in Surbiton

Excellent, professional, efficient service. Gary was quick to respond to my request for a quote and came to the property to inspect and discuss our requirements. He followed up quickly with a written quote and explained everything very clearly. On the day of installation Gary and his team worked efficiently and tidily. They were polite, friendly and a pleasure to deal with. The boiler has been running perfectly and I wouldn’t hesitate to use Complete Heating and Gas again.

Customer in Teddington

Gary was very direct and honest, responding promptly and communicating the status of his work and quote. After the initial visit, he came to my house again to ensure that the two radiators that I had ordered would fit the pipes. Gary and his team provided top-quality service – thank you!

Customer in Surbiton

Fantastic. Would recommend to all. Gary arrived early, finished early and did a brilliant job. Nice friendly guy who provides a personal touch to the job. Good price and all questions answered with no trouble. I will use again for the annual service. Thank you so much.
