Installing a new boiler is a crucial home improvement project, and the cost of labour alone can vary depending on multiple factors. If you are wondering how much to fit a boiler labour only, the cost can vary based on several factors, including the type of boiler, the complexity of the installation, and the location of your home. On average, how much to fit a boiler labour only ranges between £500 and £1,500 in the UK. The price depends on whether it is a straightforward replacement, a conversion from one boiler type to another, or if additional work, such as moving the boiler, is required.
Several factors influence how much to fit a boiler labour only, such as the expertise of the heating engineer, whether new pipework is necessary, and if extra components like a new thermostat or flue installation are needed. To get the best value, it’s advisable to compare quotes from multiple professionals.
This guide provides a comprehensive breakdown of boiler fitting costs, including pricing estimates for different types of boilers, key factors affecting installation costs, and expert tips to help you secure the best deal. Whether you are replacing an old boiler with a similar model or upgrading to a more efficient system, this guide will ensure you make an informed decision.
How Much to Fit a Boiler Labour Only?
If you’re looking to install a new boiler and only need to know the labour costs, you’re in the right place. In the UK, hiring a heating engineer to fit a boiler typically costs between £500 and £1,500, depending on several factors such as boiler type, complexity of installation, and location.
In this guide, we break down the cost of fitting a boiler, factors affecting labour charges, and how to ensure you get the best price for the job.
Average Labour Cost to Fit a Boiler in the UK
The average labour cost for installing a new boiler in the UK typically ranges from £500 to £1,500. However, these costs can fluctuate depending on several factors, including:
- The type of boiler being installed
- Whether it’s a straightforward replacement or a conversion
- The complexity of the installation
- The location of the property
- The expertise and rates of the engineer
If you are replacing an old boiler with the same type in the same location, labour costs will be on the lower end. However, if your installation involves additional work, such as moving the boiler to a different location or changing the boiler type, expect higher charges.
Labour Costs for Different Types of Boilers
The cost of installing a new boiler (excluding the unit itself) depends on the type of boiler and the complexity of the job. Below is a general price range:
| Boiler Type | Labour Cost |
|---|---|
| Combi Boiler | £500 – £1,500 |
| System Boiler | £500 – £1,500 |
| Condensing Boiler | £500 – £1,500 |
| Conventional Boiler | £500 – £1,500 |
| Electric Boiler | £500 – £1,500 |
| Biomass Boiler | £500 – £1,500 |
Labour costs remain relatively consistent across different types of boilers, but certain installations may require additional modifications, increasing the overall cost.
How Labour Costs Are Calculated
- Straight swap (same type, same location): Labour cost is on the lower end (around £500 – £800).
- Boiler conversion (e.g. from conventional to combi): Costs more due to additional work, averaging £1,000 – £1,500.
- Relocation of boiler: Moving the boiler to a new location adds around £750+ to the cost.
Factors Affecting the Cost of Boiler Fitting (Labour Only)
Several factors can influence the final labour cost:
1. Type of Boiler Being Installed
The type of boiler being installed plays a crucial role. For instance, a simple combi boiler swap is much easier than switching from a conventional boiler to a combi system, which requires rerouting pipes and removing tanks.
2. Complexity of Installation
The more complex the installation, the higher the labour costs. Some factors that make installation more complicated include:
- Converting from one boiler type to another
- Upgrading pipework
- Moving the boiler to a new location
- Replacing a back boiler system (which can take 2+ days to complete)
3. Location of the Property
Your location within the UK will impact costs. Labour costs in London and the South East are typically £200 – £600 higher than in the North of England or Wales.
4. Condition of Existing Pipework
If your existing pipework is old or doesn’t meet modern standards (e.g. gas pipes need to be upgraded to 22mm), additional work will be required, adding extra labour costs.
5. Hiring a National Company vs. Local Engineer
Large national companies like British Gas tend to charge more for boiler fitting due to their overhead costs. Hiring a local Gas Safe registered engineer can save £100 – £500 on labour costs.
Additional Costs to Consider
Besides the labour cost of fitting a boiler, there are some additional costs you may need to factor in:
| Additional Service | Estimated Cost |
| Radiator replacement (per unit) | £150 – £300 |
| Installing additional radiators | £250 – £350 |
| Water tank installation | £150 – £200 |
| New pipework installation | £800 – £1,000 |
| New thermostat | £150 – £280 |
| Moving a boiler | £700 – £1,000 |
| Boiler removal (labour only) | £50 – £250 |
How to Reduce Boiler Installation Costs
- Get Multiple Quotes: Always obtain at least three quotes from reputable heating engineers to compare labour costs.
- Choose a Local Engineer: Hiring a local tradesperson rather than a large company (e.g., British Gas) can save £100 – £500 on labour costs.
- Stick to the Same Boiler Type: Avoid unnecessary conversion costs by replacing your boiler with the same type.
- Schedule Installation During Off-Peak Seasons: Engineers tend to charge less in summer than in winter due to lower demand.
Can You Install a Boiler Yourself?
It is not recommended to install a boiler yourself unless you are a Gas Safe registered engineer. In the UK, only registered professionals can legally install gas boilers. Even for electric boilers, a professional should complete the job to ensure compliance with building regulations and safety standards.
If you install a boiler yourself without proper certification:
- You may void the manufacturer’s warranty.
- You risk gas leaks and carbon monoxide poisoning.
- Your home may fail safety inspections if you sell or rent it out.
Do I Need Additional Components During Boiler Installation?
Labour-only installation may still involve the fitting of essential components. Below are some common items that could incur extra costs:
1. Boiler Flue
The boiler flue is an essential component that safely expels gases and condensation from your home. If your boiler setup allows for a horizontal flue, the cost is usually included in standard labour fees. However, vertical flues, which require cutting through the roof, can cost an additional £300 to £600.
2. Plume Kit
Plume kits are mandatory if your boiler flue is too close to doors, windows, or neighbouring properties. These kits ensure the exhaust gases are safely vented away, and they typically cost £90 to £130, including labour.
3. Gas Pipe Upgrades
Most modern boilers require gas pipes with a diameter of 22mm, replacing older 15mm pipes. This upgrade, including labour, is essential to meet safety standards and typically adds to the overall cost.
Conclusion
The cost to fit a boiler labour only in the UK varies between £500 and £1,500, depending on the complexity of the installation. Homeowners should consider factors such as the type of boiler, the location of the property, and additional work required when budgeting for installation.
To get the best deal, compare quotes from multiple engineers, stick to a straightforward replacement if possible, and schedule your installation during off-peak periods. Hiring a Gas Safe registered professional ensures a safe and efficient installation, protecting your home and family while maximizing energy efficiency.
