Boiler Service and Gas Safety Certificate for Landlords
If you let a home, the boiler is your responsibility and so is its safety. Booking the boiler service and the gas safety check on one visit is the simplest way to keep both up to date. This page focuses on what landlords need to remember each year.

Why combine the service and the check
A gas safety check confirms appliances are safe on the day. A service goes further, cleaning and checking the boiler so it is less likely to break down mid-tenancy. Doing both in one visit means one appointment for the tenant and one date to remember. Our boiler servicing page explains what a service includes.
Setting reminders
The easiest way to avoid a lapsed certificate is to diarise the renewal date as soon as you get the record. Many landlords set a reminder two months ahead to give time to arrange access with the tenant.
Arranging access
Give tenants plenty of notice and agree a time. If you cannot get access, keep a record of your attempts, as this shows you took reasonable steps.
What it costs
The cost depends on the number of appliances, whether a service is included and the location. Our landlord gas safety certificate cost guide explains what affects the price.
Renewing early without losing your date
Current guidance allows a gas safety check to be carried out up to two months before the deadline while keeping the original expiry date. That gives you a window to arrange access without the renewal drifting earlier each year. Check the latest guidance from the Health and Safety Executive if you are unsure.
Carbon monoxide alarms
Rules on carbon monoxide alarms in rented homes have tightened in recent years. Make sure a working alarm is fitted in any room with a fixed combustion appliance, and test them at the start of each tenancy. Chris can point out where alarms are missing during the check, though fitting and maintaining them is the landlord's duty.
Between checks
If a tenant reports a fault, a smell of gas or a boiler that keeps stopping, deal with it promptly rather than waiting for the annual visit. Give tenants your contact details and the gas emergency number, 0800 111 999. For breakdowns, see our boiler repairs page.
Tenants moving out and in
The change between tenancies is a good moment for checks. With the property empty, access is easy, and any repairs can be done before the new tenant arrives. Make sure the new tenant receives the current gas safety record before moving in.
Keeping good records
The law expects you to keep a copy of each gas safety record for at least two years, give a copy to existing tenants within 28 days of the check and give new tenants a copy before they move in. Keeping digital copies alongside the paper version makes this easier. A simple spreadsheet listing each property, the date of the last check, the appliances covered and the date the next one is due helps if you manage more than one home.
Appliances that belong to tenants
Gas appliances that the tenant owns are not your responsibility to maintain, but the pipework and flues serving them still need to be safe. It helps to keep a note of which appliances you supply and which belong to the tenant, so everyone is clear at the check. Gas fires and cookers you provide are included; see our gas fire servicing page for more on fires.
