What Is a Gas Safety Certificate (CP12)?
A Gas Safety Certificate, also known as a CP12 certificate, is a legal document that confirms gas appliances and installations in a property have been checked and found safe at the time of inspection.
The certificate records which appliances were inspected, what safety checks were completed, whether each appliance passed or failed, any remedial work required, and how long the gas safety certificate lasts before renewal. Gas safety certificates are mainly required for rental properties, but homeowners may also request them for safety and insurance reassurance.
Is a Gas Safety Certificate a Legal Requirement in the UK?
Yes. Gas safety is governed by the Gas Safety (Installation and Use) Regulations 1998. These regulations place a legal duty on landlords to ensure that gas appliances are safe and regularly inspected.
A landlord gas safety certificate must be renewed every 12 months. Tenants must receive a copy within 28 days of inspection, and new tenants must be given the certificate before moving in. Missing or expired certificates can result in fines, prosecution, invalid insurance, and serious risks to tenant safety.
Who Needs a Gas Safety Certificate in London?
A gas safety certificate for landlords is required for any rented property that contains gas appliances. This includes private landlords, letting agents, and property managers.
HMOs and licensed properties often contain multiple appliances and shared systems, making gas safety certificates essential for council licensing. Blocks of flats may also require certificates where gas systems serve communal areas. Commercial premises must meet gas safety duties as part of health and safety law.
Homeowners do not legally need a gas safety certificate, but many still ask “do homeowners need a gas safety certificate?” The answer is no, but regular checks are strongly recommended.
What Is Checked During a Gas Safety Inspection?
A gas safety check and certificate inspection is thorough but non-destructive. The gas engineer visually inspects appliances such as boilers, hobs, ovens, and gas fires to confirm they are installed correctly and safe to use.
Pipework is checked for leaks, gas pressure is tested, and combustion levels are assessed to ensure appliances are burning gas correctly. Ventilation and air supply are reviewed to prevent carbon monoxide build-up. Flues and chimneys are tested to confirm harmful gases are safely expelled outside. All results are clearly recorded on the certificate.
Types of Gas Safety Certificates We Provide
We issue different gas safety certificates depending on the property type. A CP12 gas safety certificate is used for domestic rental properties, flats, and HMOs.
A CP17 certificate is provided for non-domestic installations, while CP42 certificates are required for commercial catering environments such as restaurants and takeaways. Each certificate is issued only after a full inspection by a qualified gas safety engineer.
Gas Safety Certificates for Landlords
A landlord gas safety certificate is a core legal responsibility. Landlords must arrange inspections every year, keep records, and provide certificates to tenants on time.
Gas safety certificates for landlords are commonly requested during tenancy changes, council inspections, insurance checks, and property sales. Keeping certificates up to date helps protect tenants and reduces legal risk for landlords.
Our Expert EICR Process
You can get an EICR inspection done at any time of the year. A lot of landlords have EICR tests done before new tenants move in.

Gas Safety Certificates for HMOs & Flats
HMOs and flats often require more detailed inspections due to shared boilers, communal pipework, or multiple appliances. Gas safety certificates are frequently requested during HMO licensing and renewal.
Our engineers are experienced in inspecting multi-occupancy properties and ensuring each appliance is listed and tested individually, helping landlords remain compliant.
Commercial Gas Safety Certificates
Commercial gas safety certificates help businesses meet legal and insurance requirements. Offices, retail units, and industrial premises must have gas appliances inspected regularly.
Restaurants and catering businesses require CP42 certificates because of the higher fire and gas risk. Up-to-date certification supports audits, insurance cover, and safe operation.
How Our Gas Safety Certificate Process Works
The process starts with an instant quote and booking. You provide property details and select an appointment time. A Gas Safe registered engineer near you attends the property and completes the inspection.
All findings are recorded clearly. If the property passes, your digital CP12 certificate is issued within 24 hours. If issues are found, the engineer explains what needs fixing and whether appliances must be isolated for safety.
Gas Safety Certificate Pricing in London
Many people ask “how much is a gas safety certificate?” or “how much does a landlord gas safety certificate cost?”. The price depends on the number of appliances, property size, and whether the property is residential or commercial.
We provide transparent pricing with no hidden charges. Many landlords combine a boiler service and gas safety certificate to save time and reduce overall cost.
Gas Safe Engineers – Competence & Trust
Only Gas Safe registered engineers can legally carry out gas safety checks and issue certificates. Every engineer carries a Gas Safe ID card showing the work they are qualified to do.
Our gas engineers have experience working across London’s modern apartments, older houses, converted flats, and HMOs. All work is fully insured with public liability cover, giving landlords and homeowners peace of mind.
Common Reasons Gas Safety Certificates Fail
Gas safety certificates may fail if appliances are unsafe, flues are blocked or damaged, ventilation is poor, gas leaks are detected, or safety devices are missing.
If a property fails inspection, the engineer clearly explains the issue and advises whether appliances must be isolated until repairs are completed.
Risks of Not Having a Valid Gas Safety Certificate
Without a valid gas safety certificate, landlords may face legal penalties, refused insurance claims, delayed lettings, and serious safety risks for tenants. Gas safety is about protecting lives, not just meeting paperwork requirements.
Tenant Rights & Responsibilities
Tenants have the right to receive a copy of the gas safety certificate and request proof of annual checks. Tenants must allow access for inspections and report gas safety concerns promptly. They must never attempt gas repairs themselves.
