Problem & Solution

Signs your Hornsey boiler needs replacing

If your boiler can be repaired instead. Most of Hornsey is Victorian and Edwardian terraces — Middle Lane, Tottenham Lane, Rokesly Avenue and up through Crouch End towards Harringay. Heating systems in these properties vary. Some still run back boilers that are long overdue replacement. Others have ageing combis that are costing more in repair visits than a new unit would over the next few years. We assess the property before recommending anything. Supply and fit from £1,800, covering the new boiler, flue, all connections, system flush, and Gas Safe certificate. Most installs in a standard N8 terrace are done in one day., see our boiler repair services. We install modern, energy-efficient boilers with long warranties.

 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is 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!

FAQ

Common Questions, Answered Clearly

Simple answers to help you make the right call.

How much does a new boiler cost in Hornsey?

Our fixed-price installations in Hornsey start from £1,800 supplied and fitted. The final price depends on the boiler and any pipework changes, and we confirm it upfront after a free survey, so the price we quote is the price you pay.

How long does a new boiler installation take?

A straightforward combi swap in Hornsey is usually completed in a single day. A system change or a first-time install can take two to three days, and we confirm exact timings at your survey.

Do you offer same-day or next-day boiler installation in Hornsey?

Yes. Subject to availability we can often survey your Hornsey home and fit the new boiler the next day, sometimes the same day. Call 020 7108 6322 to check the soonest slot.

Which boiler brands do you install in Hornsey?

We install Worcester Bosch, Vaillant, Ideal, Baxi and other leading brands. We recommend the right model and output for your Hornsey property rather than the one with the biggest margin.

What warranty comes with a new boiler?

Depending on the brand and model, warranties run up to 10 years. Because we are Gas Safe registered (918817) and register every Hornsey installation, your warranty stays fully valid.

Should I choose a combi, system or regular boiler?

It depends on your home's size and hot-water demand. Many Hornsey flats and smaller homes suit a combi, while larger houses with two or more bathrooms often work better on a system boiler. We advise at your survey.
