Issue a gas service record

Record what you did on a service, with the readings and any parts fitted, and issue it to the customer. It is the proof their manufacturer asks for on a warranty claim. It is not a CP12.

What it is

A gas service record lists the appliances you serviced on a job, what you did to each one, the readings you took, and any parts you fitted. You build it from the booking and issue it to the customer.

It is the document a manufacturer asks for when a customer makes a warranty claim, and the one a homeowner keeps to show the boiler has been looked after. It is evidence of maintenance, not a statutory certificate.

It is not a CP12

A service and a Landlord Gas Safety Record are two different jobs and two different documents. A service is maintenance: strip down, clean, check, reassemble. A CP12 is a statutory safety check a landlord must have carried out every 12 months under the Gas Safety (Installation and Use) Regulations 1998.

Issuing a service record does not discharge a landlord duty. If the job is a landlord check, issue a Gas Safety Record instead. If you did both on the same visit, issue both: they are separate records on the same booking.

Before you start

You will need a TradeBooked account on the Pro or Autopilot plan, your Gas Safe registration saved in Credentials, and a booking for the job you serviced.

Common questions

Is a service record the same as a CP12?

No. A service is maintenance on the appliance. A CP12 is a landlord's statutory 12-month safety check under the Gas Safety (Installation and Use) Regulations 1998. A service record does not discharge that duty. They are separate records, and you can issue both on the same booking.

How often should an appliance be serviced?

There is no statutory interval. Annual servicing is the usual manufacturer condition for keeping a warranty valid, and is what Gas Safe Register advise, so the record suggests 12 months. You can set whatever the appliance needs.

What if I find something unsafe?

Record the defect and the remedial action, and mark the appliance not safe to use. That never stops you issuing the record: the record is exactly what the customer needs. An unsafe situation still has to be handled under the GIUSP, and the warning notice goes on a Gas Safety Record, not here.

Do I need my Gas Safe registration?

Yes. Servicing a gas appliance is gas work, so you issue this under your Gas Safe registration. It is read from your Credentials and prefilled. If the job is assigned to a team member who holds the gas credential, theirs is used instead.

What plan do I need?

Issuing gas service records is on the Pro and Autopilot plans, the same as gas safety records.
