5.0

Heatline Renewables Ltd fitted air source heat pumps, boilers, bathrooms and other plumbing work for customers, and many of them describe Billy as polite, professional and tidy. Several reviewers say he explained the work clearly and kept in touch about arrival times. Customers report neat pipework and bathrooms, and some say the finished heating is warmer and cheaper to run than their old systems. One reviewer had a new Vaillant pump fail because of a manufacturing fault with its fan unit, and Billy came back several times, including on a Sunday, to get the heating working. A few reviewers mention fair or competitive prices.

Where do I even begin with Billy at Heatline Renewables? After a disastrous bathroom renovation, my faith in having work done at home was honestly shaken — but Billy completely restored it. Upgrading the heating system in my Grade II listed property from solid fuel to an air source heat pump was a big step, and Billy handled it with absolute professionalism and care. He brought my old house into the 21st century while respecting its character, and the standard of his work is second to none. Billy is genuinely one of the kindest, most patient and hardworking people I’ve met. Nothing was ever too much trouble, and his attention to detail is incredible — he’s a true perfectionist who takes real pride in his work. Choosing an air source heat pump has been one of the best decisions I’ve made in a long time, and I couldn’t rate Billy or Heatline Renewables more highly if I tried.

Billy installed a Vaillant 7kW heat pump, cylinder and upgraded 5 rads (including one fan radiator). He worked tirelessly for six days in total (5 days one week and a day the following) and did a very neat and professional job, keeping 'down time' for both water and space heating to an absolute minimum. The system is much more comfortable than my previous gas boiler, and cheaper to run as well. I'm delighted this install and Billy was polite, professional and tidy throughout.

Heatline Renewables installed a heat pump for us. They were polite and made installation as easy as possible. I would recommend them if you’re thinking of having a heat pump fitted. They even installed a shower as well . They also have great customer service . We are very pleased at how warm the house is now. They are also reliable and will not let you down. Thanks Billy and Frank.

We called Heatline first thing on Saturday morning due to a blocked toilet when our attempts to unblock it had failed. Billy arrived within the hour and resolved it very quickly at a really reasonable price. He also identified the underlying cause (shoddy pipe work). Great service, would recommend this company.
