Boiler Maintenance & Servicing

Heating gone off? Boiler broken? Not a problem!

We’ve been performing boiler repairs in Liverpool and the wider Merseyside area for over 20 years. Our trusted engineers can repair your boiler, heating controls, and central heating system quickly and efficiently, getting your heating back up and running as soon as possible.

We also offer boiler servicing, which is vital for keeping your boiler in good condition and for keeping your warranty.

Having your boiler serviced annually ensures your boiler is safe and operating efficiently – an efficient boiler can even save you up to 15% on your heating costs! Having a qualified engineer regularly check your boiler also allows us to catch any potential problems and perform repairs, extending the lifespan of your boiler and stopping minor issues from becoming expensive repairs down the line.

Getting your boiler serviced for winter is a good idea to check your heating is in good working order, giving you peace of mind you won’t be left without heat during the colder months. You can have your boiler serviced in the summer months to avoid peak demand.

 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!

 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! 👍⭐️⭐️⭐️⭐️⭐️
