Booked Mark for a service and advice on a new thermostat. He gave some great background information on thermostats and recommended a Tado for an app controlled device. Arranged an appointment for a couple of days later and he texted 20 minutes before arrival. He installed the Tado and quickly dealt with a couple of wiring issues linking it to my Ideal boiler. Mark was very professional, friendly and has left us with an excellent app based Tado thermostat. I would have no hesitation recommending him or using his service for any boiler issues.

Contacted Mark and he booked me in quickly. All work was explained, and completed everything at a great price. Highly recommend and I will definitely use again!!

High recommend Mark, gets you booked in quick, arrives on time, very professional and explains everything fully. I have used Mark for a few year's now. I had a problem with my boiler , he came round and had a look , i didnt realise it was still under warranty but Mark did so saved me a small fortune. Very honest and reliable

Mark @ M34 Gas is brilliant . It’s such a relief to know you can contact him if there’s ever a heating issue . Comms are great and the service is quick and prices are really spot on. Mark has fixed my boiler twice and always explains the work and how to get the best out of my boiler - thanks !

I most highly recommend Mark, he quickly booked my job in, he let me know he was on his way, arrived promptly, no waiting around. Did a great job of servicing my boiler. Cleaned up afterwards. Mark is very knowledgeable, friendly, professional. Gave me lots of advice, very helpful. Easy to talk and explained everything. I will definitely be using Mark again, he did a great job, I'm very happy I booked him and I will be recommending him to my friends and family. ⭐⭐⭐⭐⭐
