Understanding Boiler Servicing:
What Is a Boiler Service and Gas Safety Certificate?
Boiler Service: A boiler service is a thorough maintenance procedure performed by a Gas Safe registered engineer (for gas boilers) or an OFTEC registered engineer (for oil boilers). It ensures the boiler operates safely and efficiently, typically including:
- Inspection: Checking components like the heat exchanger, burner, flue, and seals for wear, corrosion, or leaks.
- Safety Checks: Testing gas pressure, flue emissions, and ventilation to prevent carbon monoxide (CO) leaks, which cause over 50 deaths annually in the UK.
- Cleaning: Removing limescale, sludge, or debris to maintain efficiency.
- Functional Testing: Verifying the pump, printed circuit board (PCB), and sensors work correctly.
- Adjustments: Calibrating the burner or gas valve for optimal performance.
- Checking gas appliances for leaks, correct pressure, and safe flue operation.
- Ensuring adequate ventilation and compliance with safety standards.
- Issuing a CP12 certificate, valid for one year, which landlords must provide to tenants within 28 days and keep for two years.
Average Cost of a Boiler Service and Gas Safety Certificate
The cost of a boiler service and Gas Safety Certificate varies depending on the provider, location, and whether they are bundled. Based on 2025 data, here’s a breakdown:
- Boiler Service Alone:
- Average Cost: A one-off boiler service for a gas combi boiler costs £80–£140, with a national average of £100 (including VAT).
- Range: Local Gas Safe engineers charge £70–£90, while national providers (e.g., British Gas, HomeServe) or manufacturer-affiliated services (e.g., Vaillant, Worcester-Bosch) charge £95–£163.
- Gas Safety Certificate Alone:
- Average Cost: A standalone Gas Safety Certificate (CP12) costs £60–£90, depending on the number of appliances checked (e.g., boiler only vs. boiler plus cooker).
- Details: This includes safety checks on gas appliances, flue, and ventilation, with a certificate issued upon completion.
- Combined Boiler Service and Gas Safety Certificate:
- Average Cost: When bundled, a boiler service and Gas Safety Certificate typically cost £80–£150, with an average of £100–£120. Many providers include the CP12 in the service price for landlords, avoiding a separate fee.
- Examples:
- Local Engineers: £80–£100, often bundling the CP12 at no extra cost.

- Add-Ons: Tasks like power flushing (£390–£720) or radiator bleeding (£90–£165) are not included and increase costs.
- Multiple Appliances: If the CP12 covers additional gas appliances (e.g., cooker, fire), costs rise by £10–£30 per appliance.
Factors Influencing Costs
Several factors affect the cost of a boiler service and Gas Safety Certificate:

- System/Regular Boilers: Cost £90–£120 due to additional components (e.g., cylinders).
- Oil Boilers: Cost £100–£150, requiring OFTEC engineers; CP12 applies only to gas appliances.
- Electric Boilers: Cost £70–£100, with no CP12 required.
- Boiler Age and Condition:
- Newer boilers (under 5 years) cost £80–£100 to service due to cleaner components.

Why Get a Boiler Service and Gas Safety Certificate?
The cost of a boiler service and Gas Safety Certificate is justified by the benefits:
- Safety:
- Servicing and CP12 checks prevent CO leaks, protecting households from risks that cause over 50 deaths annually in the UK.
- Legal Compliance:
- Landlords must obtain a CP12 annually, providing it to tenants within 28 days, to avoid fines up to £6,000 or imprisonment.
- Efficiency:
- A serviced boiler maintains 90–94% efficiency, saving £200–£400 annually on energy bills compared to an unmaintained unit with 10–20% efficiency loss.
- Warranty Compliance:
- Most manufacturers (e.g., Worcester-Bosch, Vaillant) require annual servicing to maintain warranties (2–10 years), avoiding repair costs (e.g., £300–£600 for a PCB).
- Preventing Breakdowns:
- Servicing catches minor issues (e.g., seals at £20–£50), preventing costly repairs (£200–£1,500) or emergency callouts (£100–£500).
- Extended Lifespan:
- Regular maintenance extends a boiler’s life (10–15 years for gas), delaying replacement costs (£1,500–£4,000).
