 Trustindex verifies that the original source of the review is Google. Fantastic service and fair price. The lads worked none stop for 2 days fitting my new boiler. Expert workmanship and left my house pristinely clean, with a new boiler that works perfectly. Everyone has been extremely patient and great and explaining all the aspects and elements of the job. No hard sell or pushy recommendations. Just honest fair info. Would 100% recommend. Would definitely use again if needed.

 Trustindex verifies that the original source of the review is Google. We've just had a new boiler fitted by NxtGen, they have done a great job from the initial house call to the finish of the job. They arrived when they said they would and worked hard to complete the job. The plumbers and electrician who came answered all our questions and were very competent. I'd definately recommend this company.

 Trustindex verifies that the original source of the review is Google. Fantastic,  can't rate NxtGen Heat highly enough from the initial visit and quote by Darren to the job itself and final finish by Andy and Jamie. Andy and Jamie arrived bang on 8am on day one and replaced the antiquated system in my 1907 house in 2.5 days - it was so old, as well as the old gas fire and back boiler, some of the pipework they took out was lead! The house has a lot of the original features and the guys were very sympathetic to this, using an alternative route so as to not risk damaging the covings. They made sure that I had a comprehensive lesson on how the boiler and the control panel worked before they left...and they tidied up! A++

 Trustindex verifies that the original source of the review is Google. Great service! Our boiler developed a leak a couple of days ago. A friend recommended nxtgen to me so i gave them a call. Super friendly and couldn’t do enough to help! The guys had great knowledge of our system and parts needed even though it was their first visit.  I have since had them return and service the system. If you’re looking for plumbers and installs… look no further! 👍⭐️⭐️⭐️⭐️⭐️
