Boiler Service or CP12? What Your Property Needs

The property’s use changes the answer

A boiler service and a Landlord Gas Safety Check are not interchangeable. One focuses on maintaining and checking the boiler; the other relates to gas safety responsibilities in rented accommodation. Which you need depends first on how the property is occupied, then on the gas appliances and the checks already arranged.

For a home you live in yourself, a boiler service is usually the relevant appointment if your aim is to have the appliance checked and maintained. A CP12 is not simply another name for that service. If you let a property, you need to consider the gas safety duties that apply to the rental, rather than assuming a boiler service covers them.

We work with homeowners and landlords in Ealing and across West London, and the useful starting point is always to be clear about the purpose of the appointment. Our Boiler Servicing page gives the service overview, but the distinction matters most when a property is rented or contains more than one gas appliance.

What each appointment is intended to do

A boiler service is centred on the boiler as an appliance. Its purpose is to assess its condition, operation and safety, and to identify issues that may need attention. It is maintenance of the heating appliance, not a substitute name for a landlord’s gas safety record.

A Landlord Gas Safety Check, often called a CP12, is tied to rental-property gas safety. The focus is on checking the relevant gas appliances and associated parts within the scope of the check, then recording the outcome. It is not a full maintenance service for the boiler. A safety check may identify a concern without carrying out the servicing or repair work that could address it.

That difference is important: having one appointment does not automatically mean the other purpose has been covered. If you are unsure what an existing document records, check its description and which appliances it refers to. Do not rely on the fact that an engineer visited as proof that every required check or maintenance task was included.

How the answer changes from one property to another

A home you occupy

If you own and live in the property, think about what you want checked. If the question is whether the boiler has been maintained and its condition assessed, ask for a boiler service. A CP12 is associated with landlord gas safety checks, so it may not be the right document for your situation.

A rented property with a boiler only

If you are the landlord, separate the maintenance question from the rental safety-record question. You may need to arrange the appropriate gas safety check for your responsibilities, while boiler servicing addresses the appliance’s maintenance. One should not be booked under the assumption that it automatically fulfils the purpose of the other.

A rented property with several gas appliances

The distinction becomes more significant when the property has other gas appliances, such as a gas hob or fire. A boiler service concerns the boiler. It should not be taken as evidence that other appliances have been covered. When arranging a landlord check, explain what gas appliances are present and ask what is included in the appointment and its paperwork.

A property with changing use or occupancy

A home can change from owner-occupied to rented, or have different arrangements for rooms or occupants. In these cases, do not assume that paperwork arranged for the previous use still answers the current question. Confirm the property’s present arrangement and the relevant responsibilities before booking. If you are unsure of your legal obligations, seek appropriate advice rather than treating a service report as a substitute for it.

What to clarify before booking

Before arranging work, have the property address, its current use and a list of gas appliances to hand. Explain whether you want boiler maintenance, a landlord gas safety check, or clarity about both. Ask what the appointment covers, which appliances will be included and what paperwork you will receive. Those questions help avoid a mismatch between the work requested and the record you need.

If the boiler is also showing a problem, describe the symptoms when you make the enquiry. A safety check and a repair are different tasks, and a visit focused on one purpose may not include diagnosing or resolving a separate fault. Being specific at the outset helps establish what needs to be arranged.
