Boiler Installation in Glasgow

A new boiler is one of the most important investments in your home. We supply and fit A-rated combi boilers from Worcester Bosch, Vaillant, Baxi and Glow-worm — sized for your property and installed cleanly. Every installation is priced as a guide range up front and confirmed as a fixed quote after a short survey. No VAT is charged on our installation work.

What is included in a supplied-and-fitted installation

Our installation price covers the boiler, a standard flue, controls, a magnetic filter, cleaning chemicals and materials, labour, removal and disposal of your old boiler, commissioning and benchmark registration. Travel within our coverage area is included in the overall quote — there is no separate travel charge for installations.

The exact model and a suitable output are confirmed by your engineer after reviewing your photos and the installation. Output is not selected from radiator count alone; it depends on your property's heat loss, hot water demand and pipework.

Guide prices for a straightforward combi swap

The ranges below are indicative for a straightforward same-location combi-to-combi replacement. Your fixed quote is confirmed after a short survey — we will not invent a price for an installation we have not seen.

When a standard range does not apply

Relocation, converting from a system or regular boiler to a combi, unusual flue runs, major pipework changes or substantial building work are not covered by the standard range. These need a tailored quotation, confirmed after a survey. We will always tell you before any extra work begins.

Who this is suitable for

Homeowners and landlords in Glasgow and nearby areas replacing an existing combi boiler at the same location. If you are moving the boiler, changing boiler type, or your home has unusual flue constraints, we will survey first and quote the actual work.

Frequently asked questions

How long does a boiler installation take?

A straightforward like-for-like combi swap is usually completed in one day. More complex changes — such as converting from a system boiler to a combi or relocating the boiler — may take longer. We confirm the timeline in your fixed-price quote after the survey.

Do you offer finance on new boilers?

We do not advertise finance offers. We provide guide ranges up front and a fixed-price quote after a survey, with no hidden costs.

Is travel charged on top of the installation?

No. Travel within our coverage area is included in your installation quote.
