Let me start by giving some background. I had an old system boiler with a water tank in my flat. After doing some research, I contacted Heatable to upgrade the system to a combi boiler. They asked for a few photos and sent a gas engineer the very next day to assess what would be required. After inspecting the setup, it became clear that installing the new boiler in the same location wasn’t possible due to flue length and other technical restrictions. We therefore agreed to relocate the boiler. Two days later, Heatable contacted me with a revised quote, which represented a significant increase of around 30%. After some discussion and back-and-forth, we eventually agreed on the final price. A few days later, the same engineer returned, accompanied by a helper and an electrician, and the work began. The installation took a day and a half and involved extensive copper pipework, soldering, and PVC pipes running through the ceiling. The boiler is now installed and working like a Swiss clock. I’m extremely happy with the results. They are not decorators, so there is still some internal finishing work for me to do—some minor painting and a few little drywall repairs. That said, overall, choosing Heatable was an excellent decision. I was expecting far more disruption after relocating the boiler, but that wasn’t the case at all. The team was professional, careful, and respectful of the property. It wasn’t an easy job, and it certainly wasn’t cheap, but I would definitely recommend
