What is a Landlord Gas Certificate?

A Landlord Gas Certificate, also commonly known as a CP12, is a legal document that proves all gas appliances, fittings, and gas pipe installations in a property rented out to tenants have been thoroughly inspected and deemed safe by a qualified Gas Safe registered engineer.

This certificate covers all gas appliances such as boilers, cookers, and gas fires, along with associated pipework and flues. It confirms that these appliances are operating safely and efficiently, reducing the risk of hazardous issues like gas leaks or carbon monoxide poisoning.

The CP12 ensures compliance with the Gas Safety (Installation and Use) Regulations 1998, which mandate that landlords must safeguard their tenants from potential gas-related dangers. This isn’t just a legal box to tick, it’s about creating a safe living environment for your tenants.

Why is this important?

Because safety first! Gas leaks, carbon monoxide poisoning, and faulty appliances can pose serious risks, not only to your tenants but also to the property itself. Carbon monoxide is especially dangerous due to its odourless and colourless nature, often referred to as the “silent killer.”

The Gas Safety (Installation and Use) Regulations 1998 require landlords to ensure that all gas equipment is safe for tenants. Non-compliance can lead to severe consequences, including hefty fines, invalidated insurance, and even criminal charges in extreme cases.

By securing a Landlord Gas Certificate, you’re not only protecting your tenants but also safeguarding yourself legally and financially.

Legal Requirements: What Does the Law Say?

UK law mandates that landlords must:

  • Have a gas safety check conducted every 12 months.
  • Ensure all checks are done by a Gas Safe registered engineer.
  • Provide tenants with a copy of the Gas Safety Record within 28 days of the inspection.
  • Keep copies of all Gas Safety Certificates for at least two years.

Failing to comply can lead to hefty fines or even imprisonment. Not worth the risk!

What’s Included in a Gas Safety Check?

A certified Gas Safe registered engineer will carry out a comprehensive inspection to ensure that all gas appliances and installations in your property are safe and fully functional. Here’s what’s included in the check:

  1. Inspection of Gas Appliances: The engineer will thoroughly inspect all gas appliances such as gas hobs, boilers, ovens, and gas fires. They will ensure that each appliance is operating correctly and safely, adhering to manufacturer standards.
  2. Leak Detection: One of the most critical aspects of the check is identifying any gas leaks. The engineer will use specialized equipment to detect even the smallest leaks that could pose a danger.
  3. Wear and Tear Assessment: Over time, components can degrade. The engineer will look for signs of wear and tear, corrosion, or damage to pipes, valves, and appliances that could affect safety and performance.
  4. Ventilation Checks: Proper ventilation is essential for gas appliances to function safely. The engineer will verify that there’s adequate airflow around appliances to prevent harmful gases like carbon monoxide from accumulating.
  5. Safety Device Testing: Modern gas appliances come equipped with safety devices designed to prevent accidents. The engineer will test these devices—such as flame supervision devices and pressure relief valves—to ensure they are functioning properly.
  6. Flue and Chimney Examination: Flues and chimneys are checked for blockages or obstructions that could cause dangerous gases to be trapped inside the property. The engineer will ensure that flues are properly expelling gases outside.
  7. Operational Efficiency: While safety is the primary concern, engineers also check that appliances are running efficiently. Poorly functioning appliances not only waste energy but could also be a safety hazard.
  8. Gas Pressure and Flow Checks: Engineers will check the gas pressure and flow to appliances to confirm they are receiving the correct amount of gas as per the manufacturer’s specifications.
  9. Record of Findings: Upon completion of the inspection, the engineer will document all findings in the Gas Safety Record (CP12), noting any issues that need addressing and confirming that the property meets safety standards.

Think of it as a health check-up—but for your boiler and gas appliances. A thorough gas safety check not only ensures legal compliance but also offers peace of mind that your property is safe for tenants.

Why Should Landlords Care?

  1. Tenant Safety: Your tenants’ safety should be your number one priority. Gas-related incidents can have devastating consequences, so ensuring all appliances are safe gives both you and your tenants peace of mind.
  2. Legal Compliance: Staying compliant with the Gas Safety (Installation and Use) Regulations 1998 isn’t optional—it’s the law. Regular checks help you avoid penalties, legal disputes, and even criminal charges in severe cases.
  3. Property Value: A well-maintained property not only ensures safety but also helps preserve (and even increase) its market value. Properties with a solid safety record attract better tenants who are likely to stay longer, reducing vacancy periods.
  4. Peace of Mind: There’s nothing quite like the peace of mind that comes from knowing your property is safe and compliant. Regular gas safety checks can help you sleep easy, knowing you’ve done everything possible to prevent potential hazards.
  5. Reputation as a Responsible Landlord: Demonstrating that you prioritize safety can boost your reputation. Happy, safe tenants are more likely to renew leases and recommend your property to others. Plus, showing prospective tenants that you’re a responsible landlord? Major brownie points.

Neglecting gas safety can lead to serious legal, financial, and reputational consequences. Taking proactive steps ensures you’re not only following the law but also fostering a positive landlord-tenant relationship.

How to Get a Landlord Gas Certificate

Getting a Landlord Gas Certificate is a straightforward process, but it’s important to follow the proper steps to ensure compliance and safety:

  1. Find a Gas Safe Registered Engineer: Start by locating a qualified Gas Safe registered engineer. Only certified professionals are legally authorized to perform gas safety checks and issue a valid Gas Safety Certificate (CP12). You can search for certified engineers on the official Gas Safe Register website or ask for recommendations from trusted sources.
  2. Schedule the Inspection: Once you’ve chosen a registered engineer, schedule a convenient time for the inspection. It’s crucial to coordinate with your tenants to ensure they’re available to grant access to the property. Providing ample notice and flexibility can help avoid delays.
  3. Prepare the Property: Ensure that all gas appliances are accessible and that nothing obstructs the engineer’s ability to perform the inspection. This includes clearing areas around boilers, gas hobs, and gas fires, as well as ensuring flues and ventilation points are reachable.
  4. Receive the Certificate: After the engineer completes the inspection and verifies that all appliances meet safety standards, they will issue a Gas Safety Record (CP12). This document will detail the results of the inspection, including any issues identified and actions taken.
  5. Address Any Issues: If the engineer finds any faults or safety concerns, you must address these issues promptly. Repairs may need to be completed before the certificate can be issued, especially if any appliances are deemed unsafe.
  6. Share the Certificate: Legally, you are required to provide a copy of the Gas Safety Certificate to your tenants within 28 days of the inspection. New tenants must receive a copy before moving in. Retain copies of all certificates for at least two years as proof of compliance.
  7. Schedule Future Inspections: Set a reminder for the next annual inspection. Staying proactive ensures continuous compliance and helps maintain the safety of your property year-round.

Pro Tip: Bundle your gas safety check with a boiler service. Many engineers offer combined packages, which can save time and money while ensuring your heating system stays in top condition.

How Much Does a Landlord Gas Certificate Cost?

Prices can vary based on location and the number of appliances but expect to pay between £60 and £180. Some companies offer bundled packages, including boiler servicing, which can be more cost-effective.

FAQs About Landlord Gas Certificates

Do I need a Gas Certificate for a property with no gas appliances?

If the property has a live gas supply, yes. Even if there are no appliances, the pipework needs checking.

Tenants have the right to quiet enjoyment, but safety comes first. Document attempts and communicate clearly to avoid legal issues.

Typically between 30-60 minutes, depending on the number of appliances.

If your property fails the gas safety check, the engineer will document the issues in the Gas Safety Record and may classify some appliances as “Immediately Dangerous” or “At Risk.” In such cases, these appliances will need to be turned off and repaired or replaced before the property can pass the inspection.

Final Thoughts: Stay Safe, Stay Compliant

Getting a Landlord Gas Certificate isn’t just about ticking a legal box—it’s about ensuring the safety and well-being of your tenants. Plus, being proactive can save you time, money, and potential legal headaches down the line.
