Gas Mark One
Mark is 100% reliable. You get an email to confirm your appointment, a reminder to turn off your AGA the day before. He arrives when he says he will, he is friendly but very professional. He explains what he is doing and he is very respectful. I cannot recommend him highly enough. A fantastic service.

Gas Mark One
I was delighted to employ a local well established company to repair my AGA.
I had been told by previous guys that the old AGA was ‘grizzly’ and beyond repair. This I believed for a long time. However Gas Mark One was in the area one day and the presentation of their vehicle caught my eye – so i gave them a try.
What can I say other than:
The whole appearance of the team was delightful and very professional, I received a call back the same day with an appointment.
Together with the office we were able to put together a plan for repair within a very short time. New parts were available at reasonable prices and Gas Mark one carried out the job with a high degree of knowledge – particularly Mark and a high quality service was provided.
I was pleased that they were able to repair the AGA and I didn’t have to go to the huge expense of purchasing a new one. I would gladly use this company Again

Gas Mark One
We contacted Gas Mark One prior to Christmas with a concern about our Rayburn ,Libby in the office was brilliant and passed on our concerns to Mark Who was so helpful and put our minds at ease until he could come at beginning of January to service the Rayburn.
We cannot speak more highly of the company who are professional and Mark is an expert in his field. If you want a company who not only knows their field of expertise but who cares about their customer service.
We recommend Gas Mark One.

Gas Mark One
Called out Gas Mark One on busy frost ridden day.
Engineer turned up within 24 hours. Our mains gas AGA required repairs and replacement parts it transpired. Engineer carried on his van all required AGA parts which he efficiently installed and finally re-lit to all our reliefs. Taking no more than 2 hours.
I am in the property business and recognise efficiency and integrity in delivering a most professional service. I cannot recommend more.
