Totally trustworthy and a genuinely fantastic bloke.

We recently converted our oil heating to gas. It can be unusual to have a totally easy time with tradesmen but Graham did a fantastic job and we would highly recommend him to anyone. Before starting he was very clear about all the costs and work involved. He arrived when he said he would, kept us informed at all stages of the work, completed the work on time and was extremely clean and tidy throughout. He was also very clear in explaining the heating system to us after installation and we are completely delighted!

Oil - Gas Conversion

Graham replaced the boiler in my mother's home, converting from oil to gas and upgrading radiators where necessary. He combines a technical knowledge and professionalism with a "people person" attitude and attention to detail that is simply perfect. You will not find better.

Brilliant Job

Look no further than Graham Wallace heating & plumbing if you need any work done. From first meeting Graham through to installation of a new Combi gas boiler, his advice and guidance was first class. His workmen were very experienced, friendly and courteous which made the whole process straight forward. There are always questions post installation - don't worry - Graham was on the end of the telephone to sort these. Overall a quality job, great team .... I've no hesitation in recommending Graham Wallace Plumbing and Heating.

Converting from oil to gas

Converting from oil to gas is a good move if done by the right people. I can highly recommend Graham Wallace and his team as extremely professional and dependable. Graham and Paul showed great patience and expertise resolving problems replacing an older house's previous system. Graham takes time to explain things and answer questions. I can totally recommend his guarantee of good workmanship.

Gas Installation

Finally made the decision to convert from oil to gas, my only regret, that I didn't do it sooner! Graham & his team 's professionalism shone throughout from start to finish, providing me with all the essential & necessary information I needed to know about todays's modern home heating system & how to get the most from it. I wouldn't hesitate to recommend him to anyone who was contemplating installing the gas system. Thank you for everything Graham!

Gas installation

We're so pleased Graham had been recommended to us when we finally decided to make the change to gas. From our first conversations, Graham was really good to deal with. He took time to explain exactly what would be involved and gave good advice on all the practical details - choosing a boiler, contacting the gas company and so on. The guys turned up exactly as arranged and were brilliant - a great team to have working in the house. Gas installed and completed within two days with no problems at all.
We were so impressed with Graham's professionalism and customer focus. Also really impressed with our hot water and toasty radiators!

Premium customer focus

Graham and team just recently completed our conversion from oil to gas. If customer focus is top of your agenda then look no further than Graham. Is obviously juggling more than one job at a time but always makes time for you in a friendly and approachable manner. The team were always punctual and quality of workmanship excellent. I would definitely recommend them.
