Local issues
Common heating problems in Barnet homes
High ground
Chipping Barnet sits on a hill, so exposed homes can lose heat quickly and condensate pipes are more likely to freeze.
Period homes
Older properties often have solid walls and older pipework that benefits from flushing and balancing.
Hard water
Limescale affects boilers and cylinders.
Extensions
Extended homes may need a more powerful boiler or underfloor heating.

We explain what was done, register warranties and fix any installation issue until you're satisfied.
High Barnet and Chipping Barnet sit on some of the highest ground in North London. Exposed homes lose heat faster, and condensate pipes on outside walls are more likely to freeze. A well-positioned boiler, insulated pipework and good controls make a real difference.
Victorian and Edwardian homes in New Barnet often have older radiators and pipework. Flushing the system, balancing radiators and fitting thermostatic valves can bring cold rooms back to temperature before any new boiler is fitted.
Kitchen-diner extensions are a common place for underfloor heating. We design it to work alongside your existing radiators from the same boiler, with the right mixing and controls.
If you're unsure whether your current boiler can cope with an extension, we'll assess it and tell you honestly whether a replacement is needed.
Before you call, it helps to have your boiler's make and model, any fault code shown on the display and the pressure reading to hand. If you're a landlord, let us know how to arrange access with your tenant or agent. We'll explain the options and price before any work begins in Barnet, and payment is by bank transfer on invoice.
Plan ahead
A simple heating checklist for Barnet homeowners and landlords
Late summer: service the boiler
Book your annual boiler service before the heating goes on. Small faults found in September are far cheaper to fix than a breakdown in January, and the service record keeps your warranty valid. Servicing starts from £100.
Autumn: check radiators and controls
Turn the heating on early to check every radiator in your Barnet home heats evenly. Cold patches at the bottom point to sludge; cold at the top means air. Make sure timers and thermostats are set for winter routines.
All year: keep certificates current
Landlords with property in Barnet need a Landlord Gas Safety Certificate every 12 months. Diary the renewal date and book a combined certificate and boiler service from £150 to cover both in one visit.
