Graham and his superb team carried out our oil to gas conversion in one day. We are absolutely delighted with our new gas heating system.

Graham and team did an excellent job being pensioners we were a bit concerned but needed not to be because he explained everything very clearly and would highly recommend him

Graham & his team converted the Econ 7 Heating in my 3rd Floor Apt to Gas. Graham was very professional & punctual at all times & he explained everything thoroughly to me before the work was started. The job was completed with no hassle & the team tidied up when the job was finished. This major job was completed in just over 2 days - which I was delighted with! Cannot recommend Graham & his team highly enough. Great service. Thank you Graham.😊

What can i say, Graham Wallace and his team saved us in this extreme current situation. We were without heat and hot water in the run up to this Covid-19 lockdown. Graham turned our disappointment into magic by managing to turn our gas conversion around in one day. Outstanding workmanship, friendly and clean professional service. Thank you to you all from the bottom of our hearts. Stay safe eveyone and i hope we all come out stronger once this has passed. Do not by pass Graham Wallace Plumbing & Heating Ltd, trust me you will not be disappointed. 26/03/2020

After phoning and waiting in for several missed appointments
from other companies I was delighted with the work carried out
by Graham and his trades men.Both jobs where done on the day and time as arranged.Neat clean professional service.many thanks.

Graham and team converted my old economy 7 heating to fully functioning central heating with a gas boiler. Graham's team were punctual, professional and tidy!! I have no problem recommending Graham for any central heating or plumbing contracts and will certainly be using his services again in the future!

Excellent service from start to finish. Prompt communication, very well coordinated service and very affordable. The team were excellent and all really professional and friendly. Left the house spotless after a very efficient job. Total gas install with extras in 1.5 days. Just in time for winter coming I am delighted to have a lovely warm house and heating I can rely on. I am also very confident with regards to after sales service and advice. Would be very happy to recommend!  Julie Armstrong, Bangor

Just converted from oil fired heating over to gas and selected Graham Wallace to do the job based on personal recommendations. First rate job executed by a superb crew. Job done in a day and a half. The banter flowed freely and the craic was mighty. They even lifted carpets to re-pipe 4 existing rads, re-laid carpets and helped put furniture back. Very happy customer indeed. I have no hesitation in adding to the recommendations.  Drew Patton, Belfast
