As heating engineers with over 22 years of experience in Blackheath, Charlton, Greenwich and Welling, we're often asked about boiler installation costs. While many homeowners focus solely on the boiler price, several crucial factors influence the overall installation cost. Here's our comprehensive guide to help you understand what affects the cost of your new boiler installation.
Factors that Affect the Cost of Boiler Installation
Boiler Type and Brand
The type of boiler you choose significantly impacts the installation cost. Combi boilers, system boilers, and conventional boilers each come with different installation requirements and costs.
A combi boiler might seem more expensive initially, but it could reduce installation costs by eliminating the need for water tanks. Meanwhile, conventional boilers might have a lower unit cost but require additional components like cylinders and tanks, increasing the overall installation price.
Premium brands typically cost more than budget options, but they often offer better reliability and longer warranties. We recommend considering the long-term value rather than just the initial cost.
Your Current System Type
The heating system you currently have installed plays a major role in determining costs. Converting from one system type to another typically costs more than a like-for-like replacement.
For example, switching from a conventional boiler to a combi boiler requires additional work to remove water tanks and modify pipework. Conversely, replacing your existing combi boiler with a newer model usually involves less labour and fewer materials.
Property Size and Heat Demand
Your home's size and heating requirements directly influence the boiler size you need. Larger properties generally require more powerful boilers, which typically cost more. We assess factors like:
- Number of bedrooms and bathrooms
- Radiator count
- Property insulation levels
- Hot water usage patterns
- Number of occupants
These factors help us recommend the most suitable and cost-effective boiler size for your needs.
Location of Boiler
Where your new boiler will be installed can significantly affect labour costs and materials needed. Moving a boiler to a new location typically costs more due to:
- Additional pipework requirements
- New flue installation
- Extra labour time
- Possible building work
- Decorative repairs
Sometimes, relocating a boiler can improve efficiency or free up valuable space, making the extra cost worthwhile.
System Upgrades and Additional Work
Often, a boiler installation involves more than just fitting the new unit. Common additional costs might include:
Power Flush
If your existing system contains debris or sludge, a power flush might be necessary to prevent damage to your new boiler. This additional service protects your investment but adds to the overall cost.
Smart Controls
Modern smart thermostats and controls can improve efficiency but represent an additional cost. However, they often pay for themselves through reduced energy bills.
System Filters
Magnetic filters protect your new boiler from debris and can extend its lifespan. While they add to the initial cost, they're often a worthwhile investment.
Water Treatment
Chemical treatment of your heating system helps prevent corrosion and improves efficiency. This small additional cost can significantly extend your boiler's life.
