What Happens If a Landlord Has No Gas Safety Certificate?
Failing to obtain and serve an annual gas safety certificate is one of the most serious landlord compliance failures. The consequences range from unlimited fines to a ban on serving Section 21 notices.
The Legal Requirement
Under the Gas Safety (Installation and Use) Regulations 1998, private landlords must:
- Have all gas appliances, fittings and flues inspected annually by a Gas Safe registered engineer
- Obtain a gas safety record (CP12) after each inspection
- Provide a copy of the CP12 to new tenants before they move in, or within 28 days of the annual check if an existing tenant
- Keep records for at least two years
Criminal Prosecution
Failing to obtain a gas safety certificate is a criminal offence under the Gas Safety Regulations. The Health and Safety Executive (HSE) can prosecute. On summary conviction in a magistrates' court the maximum fine is unlimited — there is no cap. Cases involving injury or death can result in custodial sentences.
Section 21 Notices
Since the Deregulation Act 2015, a landlord cannot serve a valid Section 21 (no-fault eviction) notice unless they have served the current gas safety certificate on the tenant. If a valid CP12 was never served at the start of the tenancy, many courts have held that this cannot be retrospectively remedied, permanently blocking Section 21 for that tenancy.
Impact on Selective Licensing
Most London boroughs with selective licensing schemes require landlords to keep gas safety records up to date as a licence condition. Breach of licence conditions can result in revocation of the licence and a banning order preventing the landlord from managing or letting property.
Insurance Voidance
Most landlord building and contents insurance policies require compliance with statutory gas safety obligations. A claim made on a property where the gas safety certificate has lapsed may be declined.
Civil Claims from Tenants
Tenants who suffer injury or loss related to a gas appliance in a property without a valid CP12 can bring a civil claim against the landlord. Courts are likely to find the landlord at fault given the clear statutory breach.
What to Do If You Are Out of Compliance
Book an inspection immediately — do not wait. Once the certificate is issued, serve it on the tenant as quickly as possible. Consider whether a Section 21 has been irreparably compromised and seek legal advice if eviction is likely.
Frequently asked questions
Can I serve a Section 21 if I never gave the tenant a gas safety certificate?
Most courts hold that failing to serve the CP12 at the start of the tenancy cannot be remedied retrospectively, permanently blocking Section 21. The Trecarrell House v Rouncefield Court of Appeal decision in 2020 created some nuance but the safest position is to always serve before tenancy start.
How quickly do I need to get a gas safety inspection done?
As soon as possible — every day of non-compliance carries risk. Gas Safe registered engineers typically attend within a few days. Do not wait until the tenancy renewal.
What if my tenant refuses access for the gas safety inspection?
Keep written records of every access request. Landlords must make three documented attempts before the HSE will accept that the landlord has taken all reasonable steps. You may need to apply to the court for an access order.
Does a gas safety certificate cover the gas meter?
No. The gas meter is the responsibility of the gas transporter (National Gas) or the meter operator. The CP12 covers appliances, installations and flues within the property.
