How Much Does a New Boiler Cost in 2026? Complete Price Guide

How much a new boiler costs in 2026 depends on far more than the boiler itself. The final price is affected by the type of system you have now, whether the boiler stays in the same position, flue requirements, controls, pipework and the condition of the heating system.

At AR Heating & Gas, straightforward new boiler installations start from £1,790 fitted. The important thing is to compare the complete installed price rather than a boiler-only headline.

What is included in a new boiler price?

A proper installation quote should make clear what is and is not included. Depending on the job, that can cover the boiler, flue, controls, filters, required pipework changes, system cleaning, commissioning and registration.

If two quotes look very different, compare the scope rather than just the number at the bottom. Moving a boiler, changing system type or correcting old pipework can change the job significantly.

Combi, system or heat-only boiler?

Combi boilers provide heating and hot water without a separate hot-water cylinder and are common in smaller and medium-sized homes.

System boilers work with a hot-water cylinder and can suit homes with greater hot-water demand.

Heat-only boilers are often found on more traditional systems with a cylinder and additional system components.

The cheapest boiler type on paper is not automatically the right choice. Water pressure, the number of bathrooms, existing pipework and how the household uses hot water all matter.

What pushes the installation price up?

• Moving the boiler: extra gas, water, condensate and flue work may be required.
• Changing system type: converting an older cylinder or back-boiler arrangement can involve considerably more work than a like-for-like replacement.
• Flue complexity: longer or more complicated flue routes can add parts and labour.
• Old or contaminated systems: existing sludge or poor circulation may need dealing with before a new appliance is commissioned.
• Controls: the final specification may include new programmable or smart controls.
• Boiler model and output: larger or more premium appliances generally cost more than entry-level models.

Which boiler brands should you compare?

Worcester Bosch, Vaillant, Baxi and Ideal are among the mainstream names homeowners commonly compare. Brand matters, but so do the exact model, warranty terms, local parts availability and the quality of the installation.

Repair or replace?

A new boiler is not always the answer. If the existing appliance is relatively young and the fault is isolated, repair may make more financial sense. If it is older, has repeated major faults or needs an expensive component, comparing repair and replacement figures is sensible.

Our repair or replace boiler guide explains how to make that decision.
