Accredited installer

The badges that mean a longer guarantee

We're accredited to register extended manufacturer guarantees most installers can't — so your boiler is covered for far longer.

Common questions

Good to know

How does the fixed price work?

We give you a guide price from the estimator above, then confirm it exactly on a free home or video survey. Once you've agreed it, that's the price — it doesn't change once the work starts.

Can I spread the cost?

Yes — we offer interest-bearing finance on new boiler installations, subject to status. We'll show you the options with your quote.

How long does a boiler swap take?

A straight combi swap is usually done in a day. System changes or relocations can take a little longer — we'll tell you exactly when we quote.

Are you Gas Safe registered?

Yes — registration 004412. You can check any engineer on the official Gas Safe Register before they work on your gas.

What guarantee do I get?

Because we're a manufacturer-accredited installer, eligible boilers can carry up to a 12-year parts-and-labour guarantee, which we register for you on the day.
