SOUND FAMILIAR?

Need a New Boiler Installed in Barnet?

Most boiler problems don’t fix themselves — rising energy bills, strange noises, and repeated breakdowns are signs it’s time for a proper installation rather than another repair.

Old, Inefficient Boiler

Common in High Barnet’s period homes — a 15+ year old boiler is often costing far more to run than a modern replacement.

Frequent Breakdowns

Repeated call-outs and repairs on the same boiler are usually a sign it’s more cost-effective to replace than to keep patching.

Not Enough Hot Water

Common in Mill Hill and Finchley’s larger family homes — an undersized boiler struggles once more than one bathroom is in use.

Wrong Boiler for Your Home

A boiler type that was never right for your property’s size or hot water demand from the start — we’ll recommend the correct fit.

WHAT'S INCLUDED

Our Boiler Installation Service in Barnet

A complete, end-to-end installation — not just the fitting. From removing your old boiler to a fully tested, certified system.

Assess Your Home

We assess your existing system, hot water demand, and property layout, and confirm the right boiler type before agreeing a fixed price.

Remove Old Boiler

Your old boiler is safely disconnected and removed, along with any redundant pipework, tanks or cylinders no longer needed.

Install New System

Your new boiler is fitted to manufacturer specification with any necessary pipework upgrades, then connected to gas, water and flue.

Test & Certify

A full safety and performance check, system flush if required, Gas Safe certification, and a walkthrough of your new controls.

CAPABILITY

We Install All Types of Boilers

Our engineers are qualified to fit every boiler type — matched to your Barnet property, not a one-size-fits-all default.

Combi Boilers

Most popular in N20 & N12

System Boilers

Combines a boiler with an unvented hot water cylinder for strong pressure to multiple outlets — ideal for larger Mill Hill homes.

Best for multiple bathrooms

Conventional Boilers

“Our 18-year-old conventional boiler in High Barnet finally gave up. The engineer talked us through combi vs system options honestly, and the system boiler they fitted has completely solved our pressure problems.”

FAQs

Boiler Installation in Barnet — Questions Answered

Most installations are completed within a single day. A straightforward like-for-like combi swap typically takes 4–6 hours. Conversions — such as conventional to combi — or homes needing new pipework may take a full day or occasionally two. We'll confirm a realistic time estimate at the free assessment.
Costs depend on boiler type, your property size, and any additional pipework required — typically from £1,850 for a like-for-like combi swap, rising for system or conventional installations with more extensive work. All prices are fixed and agreed before work starts.

It depends on your property size and hot water demand. Combi boilers suit flats and smaller homes without space for a tank. System boilers suit larger homes with multiple bathrooms. Conventional boilers often suit period properties with an existing tank setup, common in High Barnet. We'll advise on the right fit during your free assessment.
