 Trustindex verifies that the original source of the review is Google. Absolutely delighted with the service from Cortech Plumbing. I recently had a new combi boiler installed and the entire experience was outstanding from start to finish. The team was professional, punctual, and extremely knowledgeable throughout the whole process. They took the time to explain everything clearly, worked efficiently, and left everything spotless when the job was completed. The quality of the installation is top class and the difference in heating and water pressure has been incredible. What really stood out was how easy and stress-free they made everything. Genuine, reliable tradesmen who clearly take pride in their work. I couldn’t be happier with the result and would highly recommend Cortech Plumbing to anyone looking for a boiler installation or plumbing work. Brilliant service all around.

 Trustindex verifies that the original source of the review is Google. We recently engaged with Cortech plumbing to get both our pump and hot water issue resolved. Initially we replaced our pump due to a leak - and then investigated the hot water issue, after being left on a hold for a considerable amount of time, Ben contacted us and took ownership of what had happened - which was appreciated. Although it was difficult to find exact source of the issue for the hot water, we initially were to replace the element within the boiler but we had to go ahead with a full replacement. Although this process did take longer than expected to get it sorted - we’re happy with the overall result. Cheers!
