Landlord Gas Safety Record (CP12)

A free Landlord Gas Safety Record (CP12) generator. It fills a one-page LGSR (Form v3.2) in your browser. Only a Gas Safe registered engineer may carry out the checks and issue the record. The engineer who signs it is responsible for its accuracy.

Your answers never leave this device. The page does not upload the form, store customer data, or send analytics about what you type. You may optionally keep your own engineer details in this browser.

This tool is for Gas Safe registered engineers. It does not make MyBoiler.com, or anyone named on this site, a Gas Safe registered business.

Step 1 of 10 — Certificate

Certificate

Certificate number is optional. If you leave it blank, a number is filled in automatically when the PDF is generated (the local date and time, for example 20261111-164530).

Guidance only. Gas work, safety checks, and the issued record remain the responsibility of the Gas Safe registered engineer. Form v3.2. The PDF is built on this device from the blank template.
