Replacing a boiler is one of the biggest investments many homeowners make, so it's perfectly natural to want to know how much it will cost before contacting an installer.

At APV Heating Services, we've introduced an online quotation tool that allows homeowners across Tunbridge Wells and the surrounding areas to receive an instant estimate for a new boiler installation in just a few minutes.

What is the Average Cost of a New Boiler in 2026?
The cost of a new boiler depends on several factors, including:
- The type of boiler you need
- The size of your home
- The number of bathrooms
- Your current heating system
- Whether the boiler is staying in the same location
- Any upgrades needed to pipework or flues
As a general guide, homeowners can expect to pay:
| Boiler Type | Typical Installed Cost |
|---|---|
| Combi Boiler | Around £2,700–£3,000 |
| Heat Only Boiler | Around £2,600–£2,900 |
| System Boiler | Around £3,000–£3,400 |
These figures include professional installation by a Gas Safe registered engineer and are intended as a guide. Every home is different, which is why obtaining a tailored quotation is always recommended.
What Affects the Cost of Replacing a Boiler?
Many people assume all boiler installations cost roughly the same, but that's rarely the case.
Several factors can influence the final price.
Existing Boiler Type
Replacing a combi boiler with another combi is generally simpler than converting from a conventional heating system.
Boiler Size
Larger homes with more radiators and bathrooms typically require a higher output boiler.
Moving the Boiler
If you'd like your boiler relocated, additional pipework and flue work may be required.
Heating System Upgrades
Older systems sometimes benefit from upgrades such as magnetic filters, improved controls or a system flush to maximise efficiency and protect your new boiler.

Frequently Asked Questions
Our online quote provides an excellent estimate based on the information you enter. Before installation, we'll carry out a survey to confirm the specification and ensure the recommended boiler is the right fit for your home.
Vaillant, Worcester Bosch and Ideal all manufacture excellent boilers. The best choice depends on your property, your heating requirements and your budget.
Most standard boiler replacements can usually be completed within a single day, although more complex installations may take longer depending on the work required.
A modern, well-maintained boiler will typically last between 10 and 15 years, although many continue to operate efficiently for longer with regular servicing and proper maintenance. If your boiler is becoming unreliable or expensive to repair, replacing it with a newer, more energy-efficient model could save you money in the long run.
Conclusion
A new boiler is an investment in your home's comfort, energy efficiency and reliability. While the final cost depends on your property and heating system, getting an estimate doesn't have to be complicated.
