Outstanding Service We cannot recommend this heating engineering company highly enough. From the very first visit, Andy, the boss, was fantastic. The girls in the office, emails and texts. Andy came out to us, calmly listened to the ongoing issues we were having with our water pressure and temperature, reassured us, and clearly explained two different options for resolving the problem. Everything was explained in detail, with no pressure at all. We were booked in promptly, and on the agreed day Andy arrived on time with Carl, the senior engineer. The work took two days, Jeorge joined the team and throughout the entire job the team were absolutely amazing. Every engineer we dealt with was polite, friendly, professional and clearly took pride in their work. They worked incredibly hard, kept us informed throughout, and went above and beyond to make sure everything was done properly. At the end of each day, they tidied everything up and left the place spotless. It really was a pleasure having such a professional and respectful team in our home. They genuinely couldn't do enough for us, and we are extremely grateful for all their hard work.

I had 7 radiators replaced and from the estimate to the finish, HEH were professional and thorough throughout the whole process. Little things like putting down plastic sheets where they walked through the house make a difference as well as friendly and courteous staff. Would definitely recommend.

I’ve used HCH since they installed our boiler 8 years ago. Since then they have serviced the boiler annually. They are consistently reliable providing quality service with a team of professionals. My engineer today was of the same standard , friendly , polite and informative. Great service.

We’ve used HEH for a number of years for the annual servicing of our gas fire and boiler. It’s always arranged and carried out very efficiently and combined with the discount (for boiler and fire), they are competitive. After long running problems with our Hive, we asked for suggestions to replace and now have a Heatmiser Neo installed (by HEH) which is much more reliable. The staff are all very friendly and helpful and service from all is second to none. We highly recommend.

This company installed my boiler in 2024. Everyone you speak to or have working in your home from this company is so friendly and professional. Their communication is excellent and they arrive on time following a text to confirm the engineer is on his way. Billy was a pleasure to meet and the work carried out was done with care. A highly professional service from this great company. I would definitely recommend them to anyone who needs a new boiler or service.

I would highly recommend this very professional company. Mine was a challenging boiler replacement job requiring the installation of a new gas run and pipe work changes. After detailed expert consultation, the work was carried out exactly as agreed, on-time, neatly and efficiently by a very competent team, and the final invoice was fully in line with the original detailed quotation. Absolutely five star.

After returning from Edinburgh on Tuesday evening, 30th June, we found our gas boiler to have failed. I phoned HEH the following morning to request an engineer to call and one was dispatched that same day. He advised that, whilst the boiler could be repaired, the parts alone would be very expensive, so he suggested that because of the boiler’s, age, a new one might be a better option. This chimed with our thoughts exactly so I contacted HEH and said we would like to go ahead with a a new one. Andy, the owner, came up the next morning to assess the situation. On Saturday, 4th July, today, two engineers arrived as promised at about 8.15 a.m. and began their work immediately fitting the new system. Without any seeming effort, the whole work was completed by 11.45 a.m. including adjusting the timer settings to our specifications, explaining how to change the times and temperatures, removing all the old material and leaving the place spotlessly clean. They were cheerful, polite, knowledgeable, and immaculately turned out. Both of them fulfilled the ethos of HEH in an exemplary way. As in my past reviews, I have nothing but the highest praise and thanks for the work they have undertaken on my behalf. They are the standard to which other companies should aspire.

Since I moved they have fitted new boiler, new radiators, underfloor heating and now reconnected my gas cooker after having had a new kitchen extension. All the lads are great, friendly and knowledgeable they work really hard and never leave a mess. They have had to do a lot of work bit by bit and have always fitted me in within a couple of weeks. Thanks to all the lads and not forgetting the office staff. Highly recommended.

Had a new boiler fitted-was on contract with another provider but will be leaving them and going with this company! All parts of service provided were excellent, from communications with the office, to the engineers attending to carry out the work. Workmen on time ( which is something these days!) polite and friendly, worked late until new boiler operating correctly, explained operation clearly. Would definitely recommend this company!

Recently had a new boiler system put in by High Efficiency Heating and couldn’t be happier! Was no small job the lads had to do either. Ripping out the old system (water tanks etc) and connecting the new system with new pipe work etc. absolutely fantastic job! Very neat and tidy and left our home absolutely spotless when complete. Also took extra care in our babies room laying out sheeting and covering which was really good of them as the room was all brand new. Fantastic from start to finish! Huge thankyou!
