If you’re searching for cheap boiler installation London, you’re likely trying to balance affordability with safety and quality. While low prices can be appealing, it’s important to understand what’s included – and what’s not – before choosing an installer.
In this guide, we explain how to find affordable boiler installation in London, what affects pricing, and how to avoid hidden costs while still getting a reliable, professionally installed system.
A cheap boiler installation doesn’t necessarily mean the lowest price advertised online. Instead, it means:
Fair, transparent pricing
Installation carried out by Gas Safe registered engineers
No unnecessary extras added later
In London, a cheap new boiler installation typically ranges from £1,800 to £2,500, depending on the boiler type and complexity.

| Combi boiler installation | £2,000 – £2,600 |

1.Boiler Type
Combi boilers are often the most cost-effective option for smaller properties, while system or regular boilers may increase costs due to additional components.
2.Property Size & Layout
Larger homes may require:
Higher output boilers
More labour time
Additional pipework
This can affect the final low cost boiler installation London price.
3.Installation Complexity
Factors such as relocating a boiler, upgrading pipework, or changing boiler type will increase costs – even when choosing a budget installation.
| Common Hidden Cost | How to Avoid It |
|---|---|
| Extra labour charges | Confirm installation scope upfront |
| Pipework upgrades | Ask if upgrades are included |
| Exclusions in quotes | Choose fixed-price installations |
Cheap boiler installations should still include clear pricing and professional standards.
Affordable installations are worth it if:
The boiler is sized correctly
Installation is Gas Safe compliant

However, extremely low prices may indicate:
Inexperienced installers
