What Is a Gas Safety Certificate (CP12)?
A Gas Safety Certificate, officially known as a CP12 certificate, is a legal document that confirms all gas appliances, pipework, and flues in a property have been inspected and deemed safe to use. This certificate is issued after a qualified Gas Safe engineer has completed a thorough examination of your property’s gas installations.
The CP12 record details every gas appliance checked, identifies any defects found, and confirms whether the property meets current safety standards under the Gas Safety (Installation and Use) Regulations. Each certificate remains valid for 12 months from the date of issue, after which a new inspection must be carried out.
Landlords must legally obtain a gas safety certificate before allowing new tenants to occupy a property, and must arrange annual renewals throughout the tenancy. Homeowners are not legally required to have a CP12, but many choose to have regular gas safety inspections for peace of mind and to maintain home insurance validity.
Gas Safety Certificate for Landlords in South London
If you’re a landlord in South London, obtaining an annual gas safety certificate isn’t optional it’s a legal obligation under UK law. The Gas Safety (Installation and Use) Regulations 1998 require all landlords to have gas appliances and installations checked every 12 months by a Gas Safe registered engineer.
This annual gas safety check must be completed before new tenants move in, and renewed within 12 months of the previous inspection throughout the tenancy. You must provide a copy of the current gas safety certificate to tenants within 28 days of the check being completed, or before they move in for new tenancies.
Non-compliance with landlord gas safety requirements carries serious consequences. Landlords who fail to maintain valid gas safety certificates face penalties of up to £6,000 per offence, potential criminal prosecution, and imprisonment of up to six months in severe cases. Beyond legal penalties, landlords may face civil liability if tenants suffer harm due to unsafe gas installations.
With local authorities across South London increasing enforcement activity in 2025, ensuring your rental properties have current gas safety certificates is more important than ever. Many landlords in areas like Wandsworth, Greenwich, and Lewisham now schedule their annual checks proactively to avoid last-minute compliance issues.
Domestic & Commercial Gas Safety Checks
Our Gas Safe engineers provide gas safety certificates for both residential and commercial properties throughout South London. Each type of property has specific requirements, and we tailor our inspections accordingly.
For domestic properties, we cover all residential settings including houses, flats, maisonettes, and Houses in Multiple Occupation (HMOs). HMO landlords should note that properties with shared facilities require particularly careful inspection, as multiple tenants rely on the same gas installations. Whether you own a single rental property in Merton or manage a portfolio of apartments in Bromley, we provide the same thorough domestic gas safety certificate service.
Commercial gas safety certificates are essential for businesses operating from premises with gas installations. Restaurants, cafes, offices, retail shops, hotels, and industrial units all require regular gas compliance checks. Commercial properties often have more complex gas systems, including commercial catering equipment, which requires specialized knowledge to inspect properly.
Mixed-use properties, common in South London’s high streets and converted buildings, require particular attention. These buildings combine residential and commercial spaces, and each section must be properly certified. We have extensive experience with mixed-use developments in areas like Croydon and Kingston upon Thames, ensuring both residential tenants and commercial occupants are protected.
What Our Gas Safe Engineers Check?
During every gas safety inspection in South London, our engineers conduct a comprehensive examination of your property’s entire gas system. This isn’t a quick visual check—it’s a methodical process that typically takes 30 to 60 minutes, depending on the number of appliances.
First, we inspect all gas appliances including boilers, cookers, hobs, fires, and water heaters. Each appliance is tested to ensure it’s operating correctly, burning gas efficiently, and not producing dangerous levels of carbon monoxide. We check flame patterns, gas pressure, and combustion efficiency using calibrated testing equipment.
Gas pipework throughout the property is examined for leaks, corrosion, and proper installation. We test pipe joints, connections, and emergency shut-off valves to ensure the entire gas distribution system is secure. Even minor gas leaks can pose serious risks, so we use sensitive detection equipment to identify problems that might not be immediately obvious.
Flue systems and ventilation are critical safety components that remove dangerous gases from your property. Our engineers check that flues are correctly fitted, properly sealed, and effectively removing combustion gases. We also verify that rooms with gas appliances have adequate ventilation to prevent carbon monoxide buildup—a particular concern in older South London properties that may have been renovated without proper consideration for ventilation requirements.
If we identify any issues during the inspection, we categorize them according to severity. Immediately dangerous defects require the gas supply to be disconnected immediately. At-risk situations may allow temporary continued use with restrictions, while observations are advisable improvements that don’t pose immediate danger. We always explain our findings clearly and provide recommendations for any necessary remedial work.
Same-Day & Emergency Gas Safety Certificates
We understand that landlords and property managers sometimes need urgent gas safety checks in South London. Whether you’re completing a last-minute property sale, responding to a local authority notice, or accommodating new tenants at short notice, we offer same-day gas safety certificate appointments across South London.
Our emergency gas safety check service can often accommodate bookings with just a few hours’ notice, subject to engineer availability in your area. We maintain a flexible schedule specifically to help landlords and homeowners who find themselves needing urgent gas compliance documentation.
Upon completion of the inspection, we issue digital CP12 certificates immediately, which can be emailed to you within minutes of the engineer leaving your property. This rapid turnaround is particularly valuable for landlords who need to provide certification to tenants quickly or to satisfy legal requirements during property transactions.
While we’re always happy to help with urgent bookings, we encourage landlords to schedule their annual gas safety checks in advance. Booking several weeks before your current certificate expires ensures you never face compliance gaps and reduces the stress of last-minute arrangements.
Gas Safety Certificate Cost in South London
The cost of a gas safety certificate in South London varies depending on several factors, but we maintain transparent, competitive pricing with no hidden fees. Most landlords and homeowners can expect to pay between £69 and £90 for a standard domestic gas safety inspection.
Several factors influence the final cost of your gas safety check. Property size plays a role—a studio flat with one gas appliance naturally costs less than a four-bedroom house with multiple gas fires, a boiler, and a gas cooker. The number and type of appliances being inspected directly affects inspection time and therefore cost.
Property location within South London can also affect pricing, particularly for same-day or emergency appointments. Commercial gas safety certificates typically cost more than domestic inspections due to the complexity of commercial gas installations and the specialized equipment often required.
We provide clear quotes before booking, so you always know exactly what you’ll pay. Many landlords with multiple properties benefit from our discounted rates for bulk bookings, making it more economical to maintain gas safety compliance across an entire portfolio.
Remember that the cost of a gas safety certificate is a necessary expense that protects lives, maintains legal compliance, and preserves your reputation as a responsible landlord. The penalties for non-compliance far exceed the cost of regular inspections.
Compliance With UK Gas Safety Regulations
All our gas safety inspections comply with current UK legislation governing gas safety in residential and commercial properties.
The primary legislation is the Gas Safety (Installation and Use) Regulations 1998, which places duties on landlords and property owners to maintain gas appliances and conduct annual safety checks.
Additional guidance comes from the Health and Safety Executive (HSE), which enforces gas safety law and publishes landlord gas safety requirements for rental properties.
From 2018, landlords must also check that working carbon monoxide alarms are installed in rooms with gas appliances, under the Smoke and Carbon Monoxide Alarm Regulations.
Our Gas Safe engineers stay current with all regulatory changes and industry best practices, ensuring your property meets every legal obligation.

Understanding UK Gas Safety Regulations
Gas safety in the UK is governed by the Gas Safety (Installation and Use) Regulations 1998, which establish clear responsibilities for landlords, employers, and anyone responsible for properties with gas installations. These regulations exist to protect people from the dangers of gas leaks, carbon monoxide poisoning, and explosions.
The Gas Safe Register is the official registration body for gas engineers in the UK. Only Gas Safe registered engineers are legally permitted to carry out gas work and issue CP12 certificates. Always check your engineer’s Gas Safe card and verify their registration number legitimate engineers expect and welcome this verification.
Recent years have seen increased enforcement of gas safety regulations, with local authorities taking a firmer stance against non-compliant landlords. In 2025, several South London councils have announced enhanced inspection programs targeting private rental properties, making it more important than ever to maintain current gas safety certificates.
For detailed guidance on your legal obligations, the UK Government’s gas safety advice provides comprehensive information about compliance requirements for landlords and property owners.
