Boiler Repair in Islington — N1, N5, N7, N19 & EC1
Islington has some of the finest Georgian and Victorian housing in North London — the Barnsbury estate, the squares around Canonbury, the period terraces running down Upper Street and Essex Road, and the older stock throughout Highbury and Holloway. These properties are wonderful to live in but older heating systems in period buildings come with specific failure patterns: low pressure from ageing pipework, heat exchanger scaling from hard London water, and worn diverter valves in systems that have not been serviced in years. Koncore covers the full borough. We work across Angel, Highbury, Barnsbury, Canonbury, Holloway, Archway, Tufnell Park and Clerkenwell every day. Same-day appointments available across N1, N5, N7, N19 and EC1.? Koncore Plumbing & Heating provides professional boiler repairs carried out by Gas Safe registered engineers, helping homeowners and landlords get their heating systems back up and running without delays. Whether your boiler has completely broken down, is leaking, losing pressure, making unusual noises or not turning on at all, we carry out accurate fault diagnosis and fix the issue properly not just a temporary patch.
We repair all major boiler brands including Vaillant, Worcester Bosch, Ideal and Baxi across Islington, Angel, Highbury, Canonbury, Barnsbury, Holloway and nearby areas such as Finsbury Park and Archway. With fast response times, same-day availability where possible and fixed pricing with no hidden costs, you’ll know exactly what to expect, with most faults resolved on the first visit wherever possible.
If your boiler is no longer cost-effective to repair, we also provide boiler installation in Islington with modern, energy-efficient systems and long warranties. To help prevent future breakdowns and keep your system running efficiently, we also offer boiler servicing in Islington

Mohammed is excellent. He is always on time, totally professional and helpful. My tenant is very happy, and that is important to me. I will be using Koncore Plumbing & Heating from now on. New Review April 2026: Mohammed and his team have replaced my old boiler, which had reached the end of its life and had caused a leak to the property below. A thorough investigation to check all pipework in the affected room, and removal of sodden insulation material (itchy stuff). Boiler fully commissioned, and Hive working too. Once again tenants are happy. Thank you so much once again Mohammed - you are amazing and helped me out so much.Posted on Google![]()

Mo & the team did a very quick and brilliant job replacing our boiler. We have had trouble with the previous boiler for the last year and unfortunately it finally died on us. Mo had come out previously to fix the boiler and when it eventually died we came back to him and his team. Would highly recommend!
