Mains Gas Ltd is described by most reviewers as polite, professional and tidy, with several saying they would recommend the firm. Boiler installations and services are reported as completed to a high standard, with clear explanations and advice, and reviewers often mention good communication from the office and engineers. One reviewer said a problem was sorted within an hour, and another reported a minor post-installation airlock fixed after hours on a Friday evening. However, one reviewer said a £203 repair did not fix the boiler and that a new boiler was then recommended, with the full amount still charged. Another described the firm as unhelpful over the phone and unwilling to accommodate appointment times.
Excellent service from Mains Gas from start to finish. We recently had a new oil boiler installed and the whole process was smooth and stress-free. The engineers were professional, tidy, and completed the work to a very high standard. Everything was explained clearly, and the new boiler is working perfectly. We would highly recommend Mains Gas to anyone looking for reliable and trustworthy heating engineers. Quality work at a fair price. Thank you again!
After having several heating engineers look at our heating system over the years, I can honestly say that Mains Gas have been the most professional, knowledgeable, and reliable company we have dealt with. From the initial survey through to the installation of our new boiler, everything was handled perfectly. They took the time to explain all of the options available, answered every question we had, and provided a clear quotation with no pressure or hidden costs. The installation team arrived on time, were polite, respectful of our home, and worked incredibly hard throughout the job. The standard of workmanship was excellent, and everything was left clean and tidy once the installation was complete. What really stood out compared to other heating engineers we have used in the past was the communication and attention to detail. We were kept informed every step of the way, and it was clear that customer satisfaction is a genuine priority for the whole team. Our new boiler is working brilliantly, the heating performance throughout the house has improved significantly, and we have complete confidence in the system. If you're looking for a trustworthy plumbing and heating company that genuinely cares about quality and customer service, I would highly recommend Mains Gas. A fantastic experience from start to finish and a company we will definitely use again in the future. ⭐⭐⭐⭐⭐
We were charged £203 to fix our oil bolier, labour and cost of the part. Fitted but did not fix the problem, came back out the next day and told we needed a new boiler. Still had the pay the full £203. I understand paying for the call out but paying for the wrong part that didn't fix the problem when they missed where the boiler was leaking from seems a little unfair. Would only have taken money off from the bill if we bought a new boiler from them. Man that came out was lovely though
superb service. The problem had been worked on with a few others but the guys from Mains sorted the issue within an hour, cool, calm and collected. Thanks!
Excellent. A complex boiler and control system installation was carried out efficiently, tidily, within budget, and without fuss. A minor post-installation hitch due to an airlock in the pump was sorted out promptly, after working hours on a Friday evening. A pleasant and polite firm, thoroughly recommended.
What a great team! From start to finish you took the stress out of overhauling our system and replacing the boiler. Excellent practical advice about what to replace our existing system with from Sam. Smooth installation by Lee and his team. We really appreciated your professionalism. Paperwork received promptly from Cath. Great instructions from Lee about operating the system (very important for those who aren't so confident with the tech). As it's been chilly since you put it in we've had a good opportunity to test it out. A big thank you. Highly recommended. Maurice and Jackie
From the very first interaction requesting a quote for an electric shower fit / replacement, I found Mains Gas to be polite and prompt with their replies. Professional service during fitment. Very happy with service provided along with competitive price for job and would use them again.

Excellent service!!
Nathan was my engineer, after a mix up over times (my fault) he came back and sorted my boiler!! 100% recommend.
This was the third time that Mains Gas have done work for me and each time everything has been of the highest standard. The actual work itself was of a very high quality and the professionalism, work ethic, and politness of the engineers was exceptional. I would highly recumbent the company.
Really impressed by Mains Gas. Two new radiators installed, exceptionally professional engineers and outstanding customer service throughout the process. Thank you so much.
Fantastic service from start to finish! Thank you Lee for getting an engineer out and completing putting a new boiler In for us. Also a thank you to Sam and Cath in the office for sorting all the paperwork. All completed over a couple of days and completely stress free. I would HIGHLY recommend using Mains Gas to anyone.
5 star service although we never actually needed them in the end.. Georgia was super helpful and patience whilst the phone service was awful. We managed to resolve the issue but had a couple follow up calls whilst their engineer was elsewhere. Defo recommend just on the communication basis 🫶🏻🫶🏻 thanks Georgia
Excellent reliable service, friendly staff. Engineers arrive the same day as calling and fix any problems asap.
Absolutely FANTASTIC service, engineers and office staff couldn't be more helpful, punctual and hard working. They really are excellent and for me the reliability and trustworthiness of the whole team was a key factor. I will use them for everything I need and have already recommended them to my neighbours!
A great local business, very pleased with the service and team.
Outstanding service and level of support when we encountered a problem with our boiler. Highly recommended!
Brilliant service from Mains Gas Brecon. Heating went off right before a temp hit minus figures they came out as soon as they could and got the heating back on working that day. Definitely a recommend company if in doubt check out he local Facebook group they are always recommend in the area by locals.
We were impressed with Mains Gas after a boiler service earlier in the year and asked for a quote for a far larger piece of work involving a further boiler and a remapping of the whole HW and CH system to create two separate systems in one property. This proved to be complex, tiresome and fraught with difficulties after decades of poor installations and repairs during previous ownership. In delaing with this over only three days, the team were professional, efficient, considerate and tidy. It was also all done at a very reasonable price. It's a surprise and delight to deal once again with a firm that exercises attention to detail and takes pride in their work, in an industry where so many do not. I recommend Lee and his entire team highly. First rate.
We telephoned and arranged for an engineer visit to assess the possibility of restoring our boiler to working condition or to receive a quote for a new one, including supply and installation. Lee arrived as scheduled, conducted a thorough inspection, and provided pricing for both repairing the old boiler and installing a new one, fully fitted and guaranteed. We opted for the new installation and set a date for the work. Lee and his team arrived on time, removed the old boiler, swiftly installed the new one, cleaned up the area, and conducted tests. They also disposed of all the rubbish and the old boiler and pipework. Lee was very polite and helpful from our first call through to the completion of the job. They did a fantastic job. We cannot express enough gratitude to Lee and his team for their exceptional work and their helpfulness throughout the process. Thank you, Lee. We will certainly use your services again and have no hesitation in recommending Mains Gas Limited to anyone.
Brilliant service, friendly and professional and extremely reasonably priced. Highly recommended.
Top notch service, bank holiday Monday no heating no hot water, called Tuesday first thing was answered by a very helpful lady, called Kath, she sent an engineer round that day who ordered a new part and we were all up and running the very next day... I can't thank this team enough. I highly recommend them.
Unhelpful over the phone. Wont accomodate your needs regarding appointment times. Terrible.
