Graham and his team carried out my oil to gas conversion just before lockdown in early March. They did an excellent job. Very reliable and hassle free and all work carried out for a very fair price.I would highly recommend Graham and his team.

Highly Recommended

Graham’s team recently replaced my old Baxi boiler with a Worcester Bosch. I found the team very reliable, there was minimal disturbance and the cleanliness of their work was second to none. I feel very reassured having dealt with Graham and his team if I had any problems in future they will be dealt with in a timely manner. I highly recommend Graham Wallace Plumbing & Heating.

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.Mike Nesbitt, MLA for Strangford

Graham was very reassuring and thorough in explaining what was involved in converting from oil to gas heating and I can unquestionably recommend him and his excellent team. They arrived as arranged and had the heating up and running by evening. Their detail to cleanliness and minimal disturbance was excellent. Many thanks Graham.Stanley Rolston, Belfast, 8/12/19

Emergency plumber

Discovered a leak in my mains water pipe. Contacted Graham who sent Tom round first thing next morning and confirmed the problem was the mains pipe was corroded. Tom worked for four hours tracking pipes etc and solved the problem leaving no mess and a great job done to high standard. Would highly recommend this firm without hesitation.

Excellent job

I got Graham to do a full re-plumb and conversion from oil to gas. Turned up exactly when he said he would, very reliable and did the work to an excellent standard. Very easy to work with, honest and reliable, highly recommend.Daniel Dawson, Hillsborough
