True professionals! My highest recommendation!
This is by far the easiest review I’ve ever written. Both Kieren and Tom have been an absolute pleasure to work with. They are true professionals who made the installation of our new water system and gas plumbing completely stress-free. I trusted them with the keys to my home, and they carried out the work with integrity, great communication, and without cutting corners. As with any project, a few issues arose, but they handled each one with practical solutions and a “nothing is too much trouble” attitude. I know I made the right decision choosing them, and I would not hesitate to do so again. Thank you both — you have my highest recommendation.

I would highly recommend Phoenix Heating Ltd
I recently had the pleasure of having a new boiler installed by Kieran and his helper Tom, and I couldn’t be more impressed with their service. After being without heating for over a week, Kieran went above and beyond to ensure the boiler was installed to an exceptionally high standard within just a few days. Both Kieran and Tom were incredibly polite, knowledgeable, and professional throughout the process. They worked efficiently, kept everything clean and tidy, and demonstrated great attention to detail. Beyond their technical expertise, they were also incredibly trustworthy in such a lovely way—it felt like having friends helping you out during a tough time. I am truly grateful for their hard work and dedication. They stuck to their very reasonable quote even though there were a few little extra things needed. I highly recommend their services to anyone in need of boiler installation or heating solutions. Thank you, Kieran and Tom, for going the extra mile!

Emergency Replacement of Boiler
I have known Kieran of Phoenix Heating for over 5 years. He is mine and my family's gas engineer for servicing, maintaining and installation of heating system and boiler and any plumbing issues. He is extremely knowledgeable, professional and honest and hard working who will go over and above call of duty to ensure the job is done and the client is totally satisfied. On this occasion he attended in emergency at my rental property during the recent very cold spell in November when both the heating and the the hoy water had completely stopped working. The insurance company's home emergency engineer incorrectly stated that the failure was due to dirt and debris in the system. However, Kieran attended the following day and proved that there was no dirt in the system as there was clear water flowing through the system. He gave me clear advice with pros and cons of replacing the faulty pump or considering the age of the old boiler, to replace it. As I could not leave the tenants without any heating I decided to opt for a new boiler. Although Kieran was extremely busy, he rearranged his schedule and installed a replacement Worcester Bosch boiler with 10 years guarantee the next day. He and his assistant Tom worked diligently and completed the installation in one day clearing all the mess before leaving the premises. I cannot recommend him highly enough.

Excellent work
Phoenix Heating always deliver high quality work efficiently, and are reliable and happy to give advice. On this occasion they serviced the boiler, installed TRVs on the radiators, replaced a leaking tap in the kitchen and also replaced the shower hose in the bathroom. I only mentioned the shower once they had already arrived and they sorted it out for me anyway. I always use Phoenix and highly recommend them.

They were very personable and their work was professional and clean The cost was very reasonable and we would be happy to recommend him and to use him again.

Superb WB boiler installation and genuinely lovely and capable people
Kieran is an exceptional workman. He came to assess my elderly parents new flat, which had a working, but old Potterton boiler. We had a limited budget and it was money well spent! No need to negotiate, as he's very fair! As soon as I met him, I knew he was the only man for the job. He assessed and quoted and whilst going around he found that one of the bath taps wasn't working. He said he'd be fixing that without additional charge, as it was simple, whilst the system was drained down anyway. He added a new pump and zone valves to the mega-flow, to ensure that it worked well and doesn't cause them any issues. Tom, who worked with Kieran is also superb. They both quietly, got on with the job, without fuss and apart from the fact that they are very tidy workers and remove their own rubbish, they offered and removed the painter's rubbish too! Kieran said to me "any problems, call me day or night" and I know he means that. I can't recommend highly enough! Worcester Bosch themselves recommended him to me and I understand why he gets 5 star "Which?" reviews.

New Central Heating System
The cost of a new heating system is a lot of money so choosing the right installer is so important. Saw positive reviews on the Which web site so asked Kieran to come over and give a quote. He looked over our geriatric system, fully understood it and its peculiarities and explained what he would do to improve the whole system. Kieran and his assistant were very hard working and conscientious. He updated us daily on what had been done and why and the job was completed quickly, cleanly and very efficiently. It was a brilliant job, extremely well carried out by Phoenix Heating and I would 100% recommend them and certainly will use the company for my heating needs going forward.

Highly recommended
Kieran and his assistant, Tom, installed a new boiler and Nest thermostat for us in February 2020 and also upgraded the rest of our central heating system. When he came to look at our old system he made some very practical recommendations re boiler size and flue outlet position, based on our particular needs. He arranged an installation date about 2 weeks after I accepted his estimate, The installation was carried out over two days, as promised. We had heating and water by the end of the first day. The whole process was carried out in a very efficient and calm manner, and both Kieran and Tom were both very friendly and helpful. Since the system was installed some months ago we have been very happy with how it has worked.

Real integrity - would recommend
I had a broken flush valve on a toilet and called to arrange to have this fixed. Kieran asked exactly what the problem was and then found me the part so that I could fix it myself! He even shopped around to find a local supplier. All free of charge. As far as honesty and integrity are concerned 10/10 and on this basis I would not hesitate to call this company for any work that I needed if this is an indication of how well they treat their prospective customers.

Replacement boiler and 'Nest' controls - Phoenix Heating highly recommended
I looked in Trusted Traders for one nearby, with a good number of reviews and a high score. Phoenix Heating Ltd., stood out with over 50 five star reviews. I was impressed with Kieran's speedy response and what he had to say at the initial visit. He appreciated that, as an older person, I would need the heat to be restored quickly and that the age of my 50 year old CH system also needed to be respected. He provided a quote by email quickly, with two boiler options, and various recommended additions, such as a filter, renewal of pump and valves, Nest controls, all of which were separately priced and he said were optional. I had several 'weeping' radiator valves, so he gave me a guide price per valve that would vary according to which type needed replacement. Kieran was able to fix an installation date within 12 days of me accepting the quote. Kieran and Tom arrived early on the agreed day and assured me that the heat would be back on that day. They worked well as a team, demonstrating their experience of boiler replacements. In my case the boiler had to be re-positioned, I agreed to all the optional items and they corrected the boiler by-pass . They worked until 7.30 pm to meet the promise to have the heat back on. They returned, as agreed, three days later to refill the system after flushing, install controls, correct header tank overflow and complete the job. Everything was done neatly, with complete respect for working in my home. Highly recommended.

Fantastic work - faultless from start to finish
We recently moved house and inherited a complicated two boiler setup of which half of it stopped working just as Winter hit. We wanted it simplified to one new boiler and upgraded to something more modern, a big job basically. The only person to actually give us a full quote for the work was Kieran at Phoenix. He took the time to look at the existing system and how it was setup and talked through the different options to replace and upgrade the heating/hot water and the pros/cons. He identified a number of things beyond just the boiler that would need updated (our water main and softener) to get the best out of the new boiler and cylinder. Given we had a young baby and not much heating in the house, he then moved other jobs around to start the job with his colleague Tom within a week of agreeing the quote. This included also coming out at the weekend before he started to temporarily fix the working half of our heating system which had broken. I cannot fault the quality of work or how tidy they were from start to finish. Throughout the work, he kept us updated on progress and checked any major decisions as we went along. Once everything was installed and running, he took the time to talk through how everything worked and it is clear it has been installed in a way to make it run as efficiently as possible and make servicing and maintenance easy. I cannot fault the quality of Kieran's work for us and would highly recommend him.

Professional & deserving of 5 Stars
Wanted a new boiler for my elderly mother's house and I am naturally very cautious about who we ask to carry work out in the house. Used Trusted Traders to find Kieran. He came, he saw, he quoted. On time, explained what he thought needing doing & why, with always the option to ask further questions. Quote was spot for the work being carried and it is clear that he wouldn't compromise on the quality of the parts being fitted. On the day, arrived on time with Tom his assistant and throughout was polite, professional and respectful that they working in someone's house. Always appraised of what they were doing and why, with updates as to the progress being made. Tided up afterwards and left the property clean tidy, was happy to explain the work that had been done and ensured that the boiler was correctly register with Gas Safe & Worcester Bosch. Would be more than happy to recommend Kieran to friends, relatives and colleagues. The reviews on here speak for themselves as to his professionalism.

Good, clean, quality workmanship
The first thing I noticed about Kerian, owner of Pheonix heating was that he answered his phone straight away and promptly returned any calls. I used Pheonix to replace a old Worcester boiler with a new one at a rental property I have a fair understanding of plumbing and immediately realized that they knew what they were talking about, They then carried out the replacement in one day, arriving on time, leaving the property spotless and all their work was extremely tidy which I appreciated as I'm quite fussy about pipes looking neat. I will not hesitate to give them a call when I need any more work carried out.

An outstanding, professional, 5 star job.
Kieran and his 'apprentice', Tom, replaced my 15+ year old boiler/cylinder system with a new Worcester-Bosch boiler system, cylinder, 8 TRVs and tidied up the pipe work around the same area, which had become a mess over last 20 years. They took two days for the job, arriving promptly on both days and working continuously until the job was completed. An added bonus was the laying down of a protective covering for the areas that would be affected by their work. In summary they were trustworthy, friendly, helpful, efficient and very good value for money.

Fast, accurate, clean, efficient Boiler Installation
Kieran came and gave a quote for the removal of an ageing and somewhat troublesome Keston Boiler and replacing it with a Worcester Bosch System boiler with a Nest controller. We agreed to the quote and arranged a date for installation. Kieran and his apprentice, Tom, arrived on time at 08:30 and worked solidly through until 17:30 on both days. His work is precise and meticulous and they clean up thoroughly after them-selves each day. Kieran is very knowledgeable and does not push you for extras. (A different plumber had said that we would need a power flush of our 16 year system at a cost of £900 before fitting a new boiler. However, Kieran said that the system was very clean and even though he carried the equipment to perform a power flush he said that it would only be a waste of time and money, (an honest plumber!)). As the boiler was only installed yesterday it is a bit early to tell if all is okay but it appears to be functioning as it should. Added bonus you get a 10 year guarantee on parts and labour for the Bosch boiler. Kieran is very personable and a pleasure to have in our house. A tradesman who takes a great deal of pride in his work.

Outstanding Boiler Engineer
I first used Phoenis Heating in Aug 2010 when Kieran fitted a new heating system and boiler. And then over the years, he has fitted a boiler at two further properties. He has also come over to fix any leaks or problems with other parts of my old house. In 2017, Kieran gutted and fitted a new bath room ie shower, radiator, bath, sink, toilet & tiles. His work is outstanding. I do not say that lightly - I have used other plumbers over the years but since 2010, it is ONLY Kieran because he is so good and more importantly so honest. He does not rip you off and he does a first class, reliable job. He even comes out for little jobs which I know is a hassle for him because he so busy but he does it. Since 2010, he has adopted the same methodical approach: He assesses the work to be done, advises you of it, prices it and if he cannot do it he will get in a fellow tradesman who can. He sources the equipment (bolier, radiators etc) himself and does not ask for up front payment (which he should, but he never does). The work is carried out diligently, with little mess, he clears up at the end of each day and he keeps you apprised of progress and the next stage. He does not abandon jobs half-way to start a fresh job elsewhere. I recommend him thoroughly and without reservation, having used him at least a dozen times over 9 years (3 boliers, 1 heating system, one bathroom plus little bits over the years).

Fantastic Boiler Installation
Kieran came and quoted, gave clear, helpful and impartial advice, and the came back with his colleague Tom and installed a Worcester Bosch and 10 TRVs and a remote thermostat. Throughout the work was high quality, punctual and efficient. Kieran also took the time to answer my questions and tidy up the messy pipe work around the boiler as part of the installation. It's been two months since they finished the work and I'm absolutely delighted with the new boiler and the quality of the installation. I would highly recommend Phoenix Heating and would definitely use them again.

Phoenix Heating , Professional 5 star installation.
Had to replace my 18 year old boiler so contacted Worcester who recommended several companies and passed on my details.I don’t like dealing with big companies and prefer dealing with the actual installer themselves as get a better feeling about them as past experiences with other work I had done the job gets sub contracted and not carried out by the person who originally quoted it. Kieran of Phoenix heating limited called me and arranged a time to come and see what was required. He put my mind at ease stating he was the owner of the company and the installer. I quickly read up on the reviews and was very impressed.He arrived on time and measured up and answered all questions I had. For instance I was told by another heating company that all my radiators would also require replacing, Kieran looked and said there’s nothing wrong with them and just to replace the vent plugs. Kieran sent me a detail quote for a boiler and a softner to be fitted which I accepted. He arrive on the day with another plumber to help. There standard of work was second to none. I can now understand why he has been rated 5 stars and has not had one bad review. I would recommend phoenix heating ltd to all with no hesitation. Thank you Kieran and Tom. Sean

Highly Competent, Fast, Friendly and Efficient
My central heating boiler was cycling up and down between 40 and 80 degrees very rapidly. Kieran made an initial diagnosis of the issue over the phone, citing the pump as the most likely cause. He quoted the price for a pump replacement with the caveat that other issues might be causing the problem. His initial diagnosis proved to be correct, the pump was duly changed and the problem fixed. Kieran demonstrated an in-depth knowledge of the central heating system and was able to advise me on a number of other points relating to its design and configuration. The cost of the repair was the price quoted over the phone. Kieran was highly competent, fast, friendly and efficient. A 5-star experience from end to end. Phoenix is now my go-to central heating firm. Outstanding.

Great work
Our boiler is nearly 30 years old and was last serviced around three years ago. At that time we were told that if the case came off again it probably wouldn't go back on and we'd need a new boiler. I called Kieran, he first checked that the casing clips were still available which they were although other parts were probably obsolete. When he took the casing off he said there was actually nothing wrong with the clips and proceeded to service the boiler even saying it was still in excellent condition (a fairly basic boiler with not many parts to actually go wrong) and no need to replace it at all. We would definitely recommend Kieran for his honesty and helpfulness.

Which? Local Review
We had lots of work done on our house last year and met lots of trades people. Kieran and his team were some of the best we worked with. They installed a new boiler for us in a new location, a new water tank and replaced some pipework and radiator valves. The installation/pipework is very neat and they even painted the small bit of exposed pipework white to match the utility room wall. We are very pleased with the work they did and would definitely highly recommend Kieran and his team.
