About a week ago, 2 young engineers turned up on time and instantly made a great impression. Great attitude, professional, well-mannered, and a fantastic approach to work. Much better than mine was at their age! The installation was flawless from start to finish. I honestly can't fault it, and I am deffo one of those picky annoying pricks who can find fault in anything. Mostly... Whoever trained Kieran did an amazing job. Both Kieran and Leo should be proud of themselves for outstanding workmanship. They played a blinder. Well done boys!

Great customer service from start to finish with my boiler replacement. The quotes provided for different models were clear and detailed. Lisa in the office found a very quick slot for the appointment and kept me up to date with timings etc. Boiler replacement was done in less than a day. I hardly knew Kieran was in my home other than the occasional drilling. My kitchen was spotless when he left, and he also made sure he had covered the Hive app and thermostat instructions before he went. Highly professional service from all colleagues at Mark Abraham.

I have used Mark Abraham Gas Services for about 15 years. They have replaced boilers in my pub, my house, my partner's house and my mother in law's house. They have continually serviced them each year. Very efficient service, lovely friendly engineers and trusted, genuine prices. I would fully recommend them to anyone.

I loved my warm air heating but, at 34 years old, it had to go. Mark came to my home and explained my options. I had the quote later that day and the appointment was made for the following week. The work was completed in three days. Everyone was absolutely brilliant. I was nervous of changing the heating and had been putting it off for years. I can't tell you how relieved I am that it's now done. As you'll see from other reviews, everyone is professional but friendly. No messing about, but very approachable, and nothing is too much trouble. They would let me know what they were doing, and come and talk to me if they came across any issues. A solution was run past me to make sure I was happy before they went ahead. The engineers who worked so hard were Callum, Bradley and Leo. There's just one little thing to sort out, but I'm sure that will be dealt with in the same way as everything else, so I'm not in the least bit worried. Thank you ever so much. It's very rare to find tradespeople with such a culture, and you're all amazing. I'd recommend Mark Abraham Gas Services in a heartbeat! Update 24th April: Just to say that my absolute confidence was not misplaced. All sorted. 😊

Great experience from beginning to end. From the first visit from Mark to discuss the options for our new boiler and radiators, to the last day of installation with his team, the service was first class. High quality work to go with the right heating system for our needs. Faultless and professional at all times. I would highly recommend giving them a call.
