Gas Safe registration: what it means for your business admin

What Gas Safe registration covers

It is illegal to carry out gas work in the UK without being registered with Gas Safe Register (or to employ/contract someone who is not registered). The Gas Safe Register is appointed by the Health and Safety Executive (HSE) to maintain a list of businesses and engineers legally allowed to work on gas appliances, including natural gas, LPG, and oil systems.

Registration covers specific appliance types and work categories. Your Gas Safe card specifies exactly which types of work you are qualified to carry out — and you must only work within those categories. Carrying out gas work outside your registered competencies is both illegal and dangerous.

Annual renewal

Gas Safe registration is not a one-time qualification — it must be renewed every year. Gas Safe will contact you before your renewal date, but keeping track of your own renewal date is your responsibility. An expired registration means you cannot legally work on gas and your insurance may be invalidated.

Renewal typically involves:

• Completing any required ACS (Accredited Certification Scheme) reassessments
• Paying the annual registration fee (currently around £200–£350 depending on the number of appliance categories)
• Confirming your business and contact details are up to date on the register

Your Gas Safe ID card

Every registered engineer receives a Gas Safe ID card with their name, a unique licence number, their employer's trading name, and a hologram. The back of the card lists the specific appliance categories the engineer is qualified for.

Customers have the right to ask to see your card before you start work. You should carry it at all times when working on gas. If a customer checks your licence number on the Gas Safe website and it doesn't match, they are legally entitled — and advised — to ask you to leave.

Record-keeping obligations

When you carry out a gas appliance service or installation, you must:

• Complete a Gas Appliance Service Record (for routine servicing)
• Issue a Landlord Gas Safety Record (LGSR/CP12) for properties occupied by tenants
• Keep copies of all records for at least 2 years
• Notify Gas Safe of any unsafe situations you identify — the Immediately Dangerous (ID) and At Risk (AR) notification procedure

Issuing Gas Safety Records to customers

For rental properties, landlords are legally required to have an annual gas safety check and must provide the tenant with a copy of the Gas Safety Record within 28 days of the inspection. As the engineer, your obligation is to complete and sign the record accurately. Providing it to the customer promptly — ideally by email on the same day as the inspection — keeps you organised and protects you if any dispute arises later.

Keep a digital copy of every Gas Safety Record you issue. A cloud folder organised by property address is a simple and effective system. Some trade management platforms include a document storage feature specifically for this purpose, which removes the risk of losing paper records.
