Landlord Gas Safety Checklist: What to Check Before the Engineer Arrives

Gas safety is one of those landlord jobs that is easy to leave until the renewal date gets close. That can cause problems if a tenant is hard to reach or an appliance needs repair. A simple landlord gas safety checklist helps you get organised before the annual visit and makes the inspection easier for everyone.

The legal side matters too. Landlords must arrange safety checks on relevant gas appliances and flues at least every 12 months using a Gas Safe registered engineer. Existing tenants should receive a copy of the gas safety record within 28 days of the check. New tenants should receive it before they move in.

Why Use a Landlord Gas Safety Checklist?

A gas safety inspection is more than a quick look at the boiler. The engineer may need access to the gas meter, appliances, flues and other parts of the installation. If cupboards are blocked, keys are missing or an appliance cannot be reached, the visit may take longer or need to be rearranged.

A simple checklist also helps you track dates, tenant access and any follow-up work. This is useful if you manage several properties across London.

Before booking, check what is included in a Gas Safety Certificate (CP12) inspection.

1. Check the Renewal Date Early

Do not leave the renewal until the final few days. According to the Health and Safety Executive, annual gas safety checks can normally be completed up to two months before the deadline while keeping the original renewal date, provided the timing rules are followed.

Add the expiry date to your landlord gas safety checklist and start arranging access early. This gives you more room if a tenant needs to change the appointment.

2. Confirm the Engineer Is Gas Safe Registered

Only a Gas Safe registered engineer should carry out gas work covered by the regulations. Ask to see the engineer’s ID card and check that they are qualified for the type of work being completed.

You can use the official Gas Safe Register to check whether an engineer or business is properly registered.

This should be a fixed step in your annual process, not something you check only once.

3. Make Every Relevant Appliance Easy to Reach

Before the appointment, make sure the engineer can reach the boiler, cooker, gas fire and any other landlord-provided gas appliance that needs checking. Clear boxes, furniture or stored items from around them.

The gas meter should also be easy to access. If it is inside a locked cupboard or communal area, arrange the key in advance. For busy landlords, the landlord gas safety checklist can also work as a quick handover note for a letting or managing agent.

4. Keep Vents and Flue Areas Clear

Gas appliances need the right ventilation to work safely. Make sure vents have not been covered by furniture, decorating work or stored items.

You do not need to diagnose technical faults yourself. Your job is to remove obvious access problems and let the registered engineer carry out the proper safety tests.

5. Mention Any Known Problems

If a tenant has reported a strange smell, unusual boiler noise, poor ignition or another gas-related issue, tell the engineer before the inspection starts. Do not wait for them to discover it by chance.

If an appliance is found unsafe, it may need repair, disconnection or replacement before it can be used again. You can read What Should I Do If My Property Fails the Gas Safety Check? for more detail about what happens next.

6. Keep the Gas Safety Record Properly

Once the check is complete, store the landlord gas safety record somewhere secure and easy to find. The HSE guidance for landlords states that gas safety records should be kept for at least two years.

Existing tenants should receive their copy within 28 days. New tenants should get the current record before moving in. Electronic records can also be useful when they can be stored securely and reproduced when needed.

Record keeping belongs on the checklist because the inspection itself is only one part of compliance. Once the visit is complete, update your landlord gas safety checklist with the inspection date and any follow-up action.

7. Keep Evidence of Repairs and Follow-Up Work

A gas safety record can show defects or actions that need attention. If repair work is required, keep invoices, engineer notes and updated records together.

This gives you a clearer history for the property and makes the next annual check easier to manage. It is especially useful for landlords with several rental properties or a managing agent.

If you manage more than one address, keep one landlord gas safety checklist for each property.

8. Give Tenants Clear Notice

Arrange access with the tenant in good time. Explain that the visit is for the annual gas safety check and give them a practical appointment window.

The Health and Safety Executive advises landlords to take reasonable steps to arrange access where a tenant does not immediately provide entry. Keeping records of messages, letters and appointment attempts can help show the steps you have taken.

Add tenant contact and access notes to your landlord gas safety checklist so they are not buried in old messages.

9. Do Not Confuse a Safety Check With a Boiler Service

A gas safety check and routine appliance servicing are related, but they are not automatically the same thing. A landlord should not assume that one always covers the full requirements of the other.

If the boiler is due a service, it can be useful to arrange both jobs together. When arranging your Gas Safety Certificate in London, check whether a boiler service is also required for the property.

Final Check Before the Appointment

Your landlord gas safety checklist should be simple: confirm the date, arrange tenant access, clear the appliances and meter, check the engineer’s registration, and keep the completed record afterwards.

For London landlords, good preparation can prevent missed appointments and last-minute compliance problems. If your certificate is approaching renewal, book your Gas Safety Certificate before the deadline rather than waiting for the final week.

A consistent landlord gas safety checklist makes the annual process easier to repeat across one property or a full portfolio.
