The short answer
The landlord must run a yearly gas safety check on every gas appliance in your home, and give you the certificate. Where that has not happened, they are breaking the law. You hold the right to ask for a copy. A refusal can go to the Health and Safety Executive, the HSE.
What your landlord must do by law
Under the Gas Safety (Installation and Use) Regulations 1998, landlords letting a home with gas appliances must:
- Have every gas appliance, pipe, and flue checked by a Gas Safe registered engineer every 12 months
- Give you the gas safety record, often called a CP12, within 28 days of the check
- Give new tenants a copy before move-in
The rules run in England and Wales alike.
What to do if you have not received your CP12
Start by asking the landlord in writing, email or text, so a record exists. Ask when the last check happened, and for a copy of the certificate.
No reply, or an admission that no check happened? Report it to the Health and Safety Executive. Online at hse.gov.uk, or by phone. The HSE holds powers to investigate, prosecute rule-breaking landlords, and force the work.
What about the gas appliances themselves?
A missing certificate and a faulty appliance are two separate problems. But they can link.
A boiler, gas cooker, or gas fire running badly may be a disrepair issue under Section 11 of the Landlord and Tenant Act 1985, which makes the landlord keep gas appliances working. A faulty appliance leaving you without heating or hot water may support compensation.
Carbon monoxide: act immediately
A carbon monoxide alarm sounding, or anyone in the home with headaches, dizziness, or sickness that clears outdoors, means no waiting.
Leave at once, door open, and call the gas emergency line on 0800 111 999. Never go back until a Gas Safe engineer has checked the home.
Carbon monoxide has no colour and no smell. A working CO alarm is your main protection.
What if your landlord keeps ignoring you?
A landlord who will not act leaves several routes.
Report to the HSE as above. They take gas safety seriously, and they can prosecute.
Contact the council's environmental health team. They can inspect and use their own enforcement powers where health or safety sits at risk.
A social tenant, renting from a council or housing association, can raise a formal complaint through the landlord's procedure. Unresolved, it can climb to the Housing Ombudsman.
When should I contact Support for Tenants?
Contact us where the gas check runs overdue, the CP12 stays out of reach, or gas appliances sit broken with the landlord failing to fix them. We check whether you may have a disrepair claim and refer suitable matters to an SRA-regulated panel solicitor.
No upfront cost. You only pay if you win, and the fee comes out of the compensation, not your pocket. If you don't win, you pay nothing.
Call us on 0800 030 4669.
