Plumb-Line installed a heat pump and a complete new heating and hot water system with new radiators. The team did an excellent installation job and were both friendly and very professional. New radiators were required in nearly every room and installed efficiently with great care so that no damage was done to the interior decoration. Everything was explained to me clearly.

Absolutely job Plumb -Line done for me, from the start I contacted the Vaillant to buy and install a heat pump because I heard are the best, and they sent me 3 companies for installation, and I saw Plumb Line had the best reviews, I contacted and I spoke with Adrian who came to my house for survey, he explained me all options and locations for installations, very clear , onest , profesional. My job in my opinion was very difficult because was very very small space to fit the water boiler around large 50 cm to 50 cm . Adrian found for my job the best materials from Vaillant to be fixed in that small space. And than installation week came Jason ( lovely gentleman engineer) who done this job more than perfect, was a challenge for him and for me because the space for boiler was very small and hard job to fix all in. But for us it s perfect because we do not have pipes on house , not demolition nothing. All job was in that wardrobe. All the pipes connected in boiler. And worked hard 4-5 days with another colleague and with electrician. They was amazing Jason can say was magic ✨. All clean, polite guys. 100% this company it's the best in East Midlands area. Thanks Adrian, Thanks Jason. We are absolutely happy.

Adrian, Ollie, Mat and the team were amazing! They designed and installed a bespoke heating system for us, including an air-source heat pump paired with a warm-air exchanger, replacing our home's outdated warm-air heater. They are knowledgeable and extremely responsive. Highly recommend the team. The installation team were brilliant and very knowledgeable.

Plumb-Line did a fantastic job of my ASHP install last year and I asked them whether it would be possible for them to service the system as I was nervous of getting anyone else in. Even though they're based miles away from me, they arranged the service almost immediately! Sam came today and was polite, professional and completed the service without any problems. Sophie was great and kept in touch with me to let me know he was on his way. Once again, fantastic company I would recommend highly to anyone. Thanks Plumb-Line!! :-)
