Review by Caroline Hepburn
on 23rd April 2020
"This company was recommended by my neighbour who has used them for over a decade. My hot water wasn't working and I called Marco for advice. He was honest enough to tell me that the work done by a previous company may still be under guarantee. I preferred to use Turnkey and I received prompt, professional service - when Marco visited, I was given a clear, logical explanation of the issue and a realistic estimate of the cost. By the time he left, my hot water was working, everything was left clean and tidy and he made sure I was happy with the hot water, which continues to work well. I was impressed and will be using this company again."

Review by Marco Lombardelli
on 16th April 2020
"We were initially recommended Turnkey Plumbing and Heating when we decided to build our own home. They didn't disappoint and both Massimo and Marco did an outstanding job for ourselves. Extremely professional, courteous, diligent and disciplined organisation who pride themselves on doing an outstanding job. We have now been living in our home for 10 years and without an plumbing or heating issues to date. We have had Turnkey back to our home since to undertake additional works and again all delivered to a similarly high standard. We cannot recommend this Company and their staff highly enough."
