Average Boiler Installation Cost in the UK (2026)
For most homeowners, the boiler installation cost in the UK typically falls between:
- £2,000 and £4,500+ for a new boiler with installation

What Affects the Cost of a New Boiler?
Understanding what goes into your quote helps explain why prices vary so much.
Boiler Type
Different systems come with different installation requirements:
- Combi boilers – the most common and typically the most cost-effective
- System boilers – better suited for larger homes with higher demand
- Regular boilers – often found in older systems, and can be more complex
Boiler Brand
The brand you choose has a direct impact on your boiler cost, with premium brands costing more upfront but often offering better efficiency and warranties.
Installation Complexity
A simple swap is much quicker and cheaper than a full system conversion. Additional work, such as pipe upgrades or moving the boiler, will increase the overall boiler installation cost that UK homeowners can expect.
Property Size & Demand
Larger homes or properties with multiple bathrooms may require more powerful boilers, which increases the new boiler price.
