My near 20yr old gas boiler broke down, so i called Belfast Boiler Installations (BBI) after reading their good reveiws on google and two very helpful down to earth and professional guys called out the same day.The boiler was beyond repair, so they recommended that i apply for the Affordable Warmth Scheme Grant via HE for a new boiler as i couldn't afford a new one.So on pauls advice and with his help i applied for and got grants not only for a new heating system but new radiators, and further grants for installation and new windows all down to these guys and i am beyond grateful.BBI also contacted and dealt with the grants office during the process, freeing me of that hassle before starting and during work.And they worked nonstop, i also have to point out how tidy and spotless workers they are, floor boards radiators and a hot water tank had to be ripped out and there was barely any dust or dirt anywhere, not even boot prints on the floors. A brilliant job and service from first contact to job done at an extremely fair and reasonable price.Thank you, Paul and team. I am over the moon.P.SI paid extra and opted to change to a combi boiler, and it's brilliant. The house has never been warmer. I have instant hot water, and it's so quiet compared to my old system.If you need any boiler work or a new heat system, then these are the guys.

Had my Boiler installed by Paul & Paul. Don't think I have ever come across better customer service or professionalism. I had my new boiler installed without any issues at all with my old one taken away without any hassle. My old boiler gave me a huge amount of problems & coming into winter I was very grateful I got squeezed in. Paul is a boiler expert!! Highly highly recommend their services, 10 stars !

Couldn't recommend enough, great service and genuinely nice people that care about there costumer's. Recently moved into a house that had an old gas fire attached to a back boiler which needed removed and replaced. I contacted Belfast boiler installation and spoke to Paul. They came out that same day and explained to me all the work that would need done and the different options I had, once we had decided on a plan they came back out that same week and installed the boiler. They were great at explaining everything to me and made sure I new how everything worked before they'd left I would definitely recommend them and will definitely be using them again in the future.

I couldn't recommend them enough!I contacted the business as my (very old) boiler had stopped working.I had zero understanding of how boilers work and what constitutes as a safe flue. I was extremely stressed about the whole situation and i couldn't be more grateful for how calm and knowledgeable Paul and Paul were when communicating with me and helping me understand what health and safety requirements are needed when it came to replacing my boiler and the new flue I required. They took the time to talk through what I needed and why in detail, what options I had alongside answering the million questions I asked as well!They fitted in my installation as soon as they could, helped me understand the hive app so I could control the boiler with my phone and even arranged for support to insert a wooden frame around my new flue so it is more aesthetically pleasing. I couldn't fault any of the work, communication, knowledge or kindness any of their team had. Once the boiler was installed they left my room spotless and even took away my old boiler for me too!I am very happy I found a reliable and trustworthy company to depend on. Thank you so much!!

We are very grateful to Paul & Paul (and Liam, and Gavin) for the installation of our lovely new boiler. Our 17 year old boiler needed to be replaced after failing the flue integrity check during an annual inspection. The company that did the initial inspection took 3 days to provide us with a quote despite having turned off our heating and hot water in the midst of a cold spell. When they eventually sent the quote, it was too high for the service they were offering and too late. I had already contacted 10 companies! 4 didn’t bother to respond to voicemails or emails. Belfast Boiler Installation answered my call and then proceeded to attend the property to make an assessment on the same day and within the space of just a few hours. Even when attending the property Paul kept me updated on their whereabouts and arrived when he said they would. Unfortunately a real novelty for me, so I was immediately impressed. It showed me that they had integrity. Paul & Paul made an honest assessment and laid out 3 options available to us for the installation.They took their time to explain everything and more than once (I also asked them to explain everything to my husband the following day). They patiently allowed us to ask a multitude of questions. They treated the job as a priority and managed to book us in within a few days. They gave us, what I believe was a very reasonable quote. They called us a couple of days before to explain how we needed to prepare for the installation day. On the day, they arrived on time, they had a clear plan, they completed the work with no fuss. Their collaborating partners didn’t let them down. After the installation, they explained everything we needed to know about the operation of the boiler and our new thermostat device. They had a lot of equipment but left no mess whatsoever, I mean literally no mess at all! They gave us great advice and invited us to contact them if we have any queries. Paul & Paul are clearly very knowledgeable, experienced and great at what they do. Professional, friendly, efficient, extremely competent, respectful, courteous and tidy. The communication and customer service was great. They did a great job. We would rate and recommend them very highly.

I cannot speak highly enough of Paul and Paul; our experience with them was outstanding from the moment we rang. From the very beginning, we experienced a high level of professionalism, knowledge/expertise, quality of work, and that was all at a reasonable price with the work completed in a very timely manner. Every step of the process was explained to me in such a way that I understood what was being done, the old boiler removed, and my kitchen was left in a clean state.I would highly recommend the services of Paul and Paul and will be calling on them for future servicing of the boiler.

The two Pauls replaced my gas boiler last week and set up new smart controls. They kindly fit me in at very short notice as I didn’t have any heating. They were both professional and friendly and also took time to return the following day to talk me through everything as I had to leave for work on the day they completed the work.I am very happy with the new boiler and found it quite reasonable in terms of cost. I also didn’t realise how much easier smart controls would make things! 10/10 service.
