Does a Boiler Service Include a Gas Safety Certificate?
In short: no. A boiler service is not the same as a Gas Safety Certificate (often called a CP12). While both are carried out by gas-safe professionals and relate to gas safety, they serve different legal purposes and are documented differently.
Below, we explain the difference, what each document involves, and how landlords and property professionals can stay fully compliant in the UK.
Understanding the Difference: Boiler Service vs Gas Safety Certificate
To answer “Does a boiler service include a gas safety certificate?” properly, it helps to know what each inspection is designed to achieve.
1) Boiler Service
A boiler service is a maintenance and performance check. The goal is to keep the appliance running efficiently, reduce breakdown risk, and ensure it is operating safely and properly.
2) Gas Safety Certificate (CP12)
A Gas Safety Certificate is a legal requirement for landlords. It confirms that gas appliances and pipework within a property have been checked and are safe to use at the time of the inspection.
Because of these different purposes, a boiler service typically does not automatically meet the requirements for a CP12.
Is a Gas Safety Certificate Included When You Have a Boiler Serviced?
In most cases, no—a boiler service does not include the CP12 Gas Safety Certificate.
Even though a professional will often inspect the boiler during a service, the paperwork and scope are different. A CP12 requires an inspection under gas safety legislation and includes specific checks, documentation, and certification.
Important: The only way to confirm whether you’ll receive a Gas Safety Certificate is to check what’s being booked. You should request a Gas Safety Inspection (CP12) if you need the legal landlord document.
What a Boiler Service Usually Includes
While service levels can vary by provider, a typical boiler service often includes:
• Visual inspection of the boiler and installation
• Checking for correct operation and safe performance
• Cleaning internal components (where applicable)
• Checking pressure, combustion, and efficiency (including flue/air supply checks)
• Testing safety devices
• Completing service notes and advising on any faults or recommended repairs
Some service reports may include a “safe to use” statement, but that does not replace the formal requirement for a CP12 where landlord compliance is needed.
What a Gas Safety Certificate (CP12) Covers
A Gas Safety Certificate is issued after a Gas Safety Inspection and is intended to cover:
• All gas appliances in the property (as listed/identified)
• Gas pipework supplying those appliances
• Safety checks required by the inspection standards
• Any appliances considered not safe, including advisories or required remedial actions
A CP12 is issued at the end of the inspection and includes details such as the landlord/property information, the appliances checked, the outcome, and the engineer’s registration details.
Why They’re Not the Same Legally
From a compliance perspective, the key point is that:
- Boiler servicing is maintenance and performance oriented.
- Gas safety certification is a legal landlord duty to prove gas safety at inspection time.
Landlords must arrange an annual (at least) Gas Safety Inspection and provide the relevant documentation to tenants. A boiler service alone generally cannot be used as evidence that the full CP12 inspection has been completed.
How Often Do You Need a Gas Safety Certificate?
In the UK, landlords are required to obtain a Gas Safety Certificate (CP12) for gas appliances and pipework in rented properties at least every 12 months.
A boiler service may be carried out more frequently (depending on your maintenance plan), but CP12 compliance must still be maintained separately.
What Should Landlords Do If They Only Book a Boiler Service?
If you book only a boiler service, you may receive a service record but still be missing the Gas Safety Certificate that tenants and legal duties require.
To avoid delays or non-compliance, consider:
- Booking a Gas Safety Inspection (CP12) if you need the certificate
- Providing the property address and the number/type of gas appliances to be checked
- Confirming what documentation you will receive before the engineer attends
