About Us

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

Complete was formed by Gary Cousins with the vision to make boiler replacement an affordable, stress free process, for homeowners across Surrey and south London.

After spending his early days working for a national heating company, Gary picked up the skills needed to communicate and interact with customers on a personal level.

He now uses those skills to provide a first class customer service which national companies just cannot provide.

With this personal approach and high workmanship standards, Complete has grown into what it is today – the number one choice for boiler installations across Surrey and south London.

Our reputation continues to grow from our friendly, honest, impartial advice. With the help of sites like Checkatrade our positive feedback can now be shared with the world.

Thank you to all of our existing customers and a big ‘hello and welcome’ to all of our new ones! We look forward to working with you all throughout the years to come.
