Boiler replacement

Boiler replacement, done properly

A new boiler fitted right the first time — surveyed, sized correctly for your home, fully tested, and left with the paperwork to prove it. Gas Safe registered, Ideal Max accredited.

Signs it's time

How do you know you need a new boiler?

It's 10+ years old

Older boilers run less efficiently and parts get harder to source.

Frequent breakdowns

If you're calling out an engineer more than once a year, repairs are likely costing more than a replacement would.

Rising gas bills

A tired boiler has to work harder to heat your home, and that shows up on your bill.

What's included

Our boiler replacement process

1. Free survey & quote

We look at your current system, hot water demand, and where the flue and pipework need to run, then give you a fixed, upfront price — no surprises later.

2. Installation

Most straightforward swaps are completed in a day. We work tidily and protect your floors and furniture while we're in your home.

3. Full commissioning & combustion testing

Every boiler is tested with a calibrated flue gas analyzer to confirm it's burning safely and efficiently before we sign it off — not just switched on and left.

4. Certification & paperwork

You get your Gas Safe registration, Benchmark checklist and warranty registration handled — the documents you'll need for insurance or if you sell your home.
