What Our Customers Have to Say
We’re proud to be trusted by homeowners across Portsmouth, Southampton, Gosport and surrounding areas for boiler installations and repairs. Here’s what some of our customers have to say:

I used Heatology to replace an old shower/wasted space with a low profile/low maintenance walk in shower. Reife visited we discussed materials, budget & start dates. Once the work started Reife was outstanding, everything ran on time, he kept us informed of progress and cleaned up daily. The end project is fantastic, we couldn’t be more pleased. It has transformed our space and made life so much easier.

Reife was required at short notice to repair a broken cistern. He responded quickly and gave us our toilet back in short time and did it in a courteous, professional and affordable manner.
I would definitely recommend him.

Heatology redid our very outdated bathroom for us. They designed and created our dream bathroom for us. Very professional and excellent attention to detail!
Very pleased with the work carried out and would highly recommend!

I had a leak in my U-bend and posted online. Brad responded quickly and
fixed in no time. I mentioned my radiators weren’t heating properly, and he recommended a flush through, problem solved. I asked about a boiler service, and he said Reife could handle it. Not only did he service it, but he also repaired a leak and another fault.
Reliable, professional, and most importantly honest and trustworthy.

Hired them to do an electric shower replacement, which was completed flawlessly. In the process, he identified that our water meter was damaged and we also had a water leak under our kitchen sink, so a few days later he came back to fix those leaks too.
Excellent work!

After a unexpected breakdown of our shower we contacted Heatology who gave a good quote and more importantly was able to get to us quite quickly to fit new unit. The work was carried out efficiently & professionally with good advice and communication.
Highly recommended and will be in touch soon for our next project.

Highly recommend Heatology Installations, we needed some gas work completing ASAP and Reife came round and completed the work for us within 24 hours of me contacting him. Would definitely use Heatology Installations again!
Thank you so much☺️.

Highly recommend brad and reife, they redid our upstairs bathroom and our downstairs toilet as well as some odd plumbing jobs around the house. Would never use any one else!
Been using heatology for years, always excellent work. Highly recommend!
