Why You Should Get Your Boiler Serviced?
It’s tempting to skip your annual boiler service, especially when everything seems to be working fine. However, neglecting this important task can lead to higher costs and safety risks down the line.
Here’s why getting your boiler serviced is worth your time and money:
- Ensuring Safety: A boiler service involves checking for gas leaks, carbon monoxide emissions, and combustion safety. These tests protect your household from potentially dangerous scenarios.
- Maximising Efficiency: Regular servicing keeps your boiler operating at peak efficiency, helping you keep low energy costs and save money on your bills.
- Extending Lifespan: A well-maintained boiler lasts longer, reducing the frequency (and expense) of buying a replacement.
- Maintaining Warranty: Most boiler manufacturers require annual servicing to keep your warranty valid. Without servicing, you might end up footing the repair bill for issues that should have been covered.
- Preventing Unexpected Breakdowns: Routine checks can identify and fix small faults before they turn into costly repairs.
Still on the fence? Consider this simple comparison: a boiler service typically costs less than £150, while fixing a major breakdown or replacing a boiler can cost thousands.
How Much Does a Boiler Service Cost?
The cost of a boiler service in London varies depending on the type of boiler, your location, and the contractor you hire. Below are the typical price ranges you can expect:
| Boiler Type | Average Cost (Including VAT) | Time Required |
|---|---|---|
| Standard Gas Combi Boiler | £90–£150 | 1–1.5 hours |
| LPG Boiler | £100–£150 | 1.5–2 hours |
| Oil Boiler | £100–£300 | 1.5–2 hours |
| Boiler and Gas Safety Check | £100–£150 | 1.5–2 hours |
Factors That Impact Boiler Servicing Costs
Several factors determine the price you’ll pay for boiler servicing:
- Boiler Type: Combi boilers are the easiest and quickest to service, while oil and LPG boilers may cost more due to additional maintenance requirements.
- Location: Boiler servicing prices may be slightly higher in London or other major cities than in rural areas.
- Gas Safe Engineer Costs: Rates can differ depending on whether you hire a professional gas heating engineer.
- Specialised Requirements: Expect a higher price if your boiler needs extra attention, such as addressing unusual faults or servicing large commercial boilers.
What Does a Boiler Service Include?
A boiler service involves a qualified Gas Safe engineer conducting essential checks to ensure everything works correctly, efficiently, and safely. Here’s what you can typically expect during a service:
- Visual inspection of the boiler and flame to check for abnormalities.
- Comprehensive safety checks for gas leaks and carbon monoxide emissions.
- Inspect and clean the boiler’s internal components, such as burners and heat exchangers.
- Testing of gas pressure, water pressure, and overall functionality.
- Inspection of flue pipes for any obstruction or damage.
Once the service is complete, the engineer will provide you with a safety checklist or report detailing everything that was assessed.

Boiler Cover Plans vs One-Off Boiler Servicing
If you’re wondering whether you should invest in an ongoing boiler cover plan or stick to one-off servicing, here’s a quick breakdown of each option:
Boiler Cover Plans
- Average cost: £100-£200 per year on-average.
- Covers both annual servicing and emergency call-outs for breakdowns.
- Offers peace of mind, especially during colder months.
- Potential downside? Waiting times for breakdown repairs can be lengthy during high-demand periods, leaving you without heat or hot water.
One-Off Boiler Servicing
- Cost: £90-£150 per service.
- Does not include emergency repairs, making servicing a one-time expense.
- Typically cheaper in the long run if your boiler is relatively new and reliable.
The right option depends on your priorities. Many homeowners find that one-off boiler servicing is more cost-effective if their boiler is in good working condition, while a cover plan might be worth it for older or temperamental systems.
How Often Should You Service Your Boiler?
For most homeowners, having your boiler serviced once a year is sufficient. This ensures it’s ready to handle the demands of colder months without breaking down.
Best Time to Service
Engineers tend to be less busy, making it easier to secure an appointment while avoiding the last-minute winter rush.
We’ve put together a detailed blog on “Summer Boiler Service” to help you understand why maintaining your boiler during the warmer months is a smart move for year-round efficiency and peace of mind.

Special Requirements for Landlords
If you’re a landlord, the law requires you to get your tenants’ boilers serviced annually and provide a Gas Safety Certificate to ensure compliance.
What Happens if You Don’t Service Your Boiler?
Skipping annual servicing may lead to a host of issues:
- Increased risk of breakdowns during peak usage times.
- Loss of manufacturer warranty coverage.
- Potential safety hazards include gas leaks and carbon monoxide emissions.
- Reduced energy efficiency and higher heating bills.
- A shorter boiler lifespan.
Avoid these risks by scheduling regular boiler maintenance checks rather than waiting for problems to arise.
Additional Tips for Boiler Maintenance
Beyond annual servicing, you can take extra steps to maintain your boiler and heating system:
- Bleed Radiators: Remove trapped air pockets to improve heating efficiency.
- Check Pressure Levels: Boiler pressure should typically remain between 1 and 1.5 bars. Adjust if necessary.
- Monitor Your Energy Bills: Sudden spikes may indicate your boiler is working inefficiently or has an issue that needs attention.
- Look for Leaks: Spotting a leak early can save you from a bigger problem.
