A landlord gas safety certificate — officially called a Gas Safety Record or CP12 — is a legal document that confirms all gas appliances, pipework, and flues in a rental property have been inspected and are safe to use. It is issued by a Gas Safe registered engineer after a thorough safety inspection. Under the Gas Safety (Installation and Use) Regulations 1998, every landlord in England and Wales must arrange an annual gas safety check on all gas appliances they own and provide to tenants. This includes gas boilers, gas fires, gas cookers, gas hobs, and gas water heaters. The check must be completed within 12 months of the previous inspection. A copy of the Gas Safety Record must be given to existing tenants within 28 days of the check, and to new tenants before they move in. Landlords must keep records for at least 2 years. Failure to comply can result in prosecution, fines of up to £6,000, and imprisonment in serious cases. We carry out gas safety inspections for landlords across Barry, Cardiff, Penarth, Bridgend, Cowbridge, Pontypridd, and the Vale of Glamorgan. We offer competitive rates, multi-property discounts, and reminder services to ensure you never miss a renewal date. ## The Consequences of Non-Compliance Operating a rental property without a valid gas safety certificate is a criminal offence. Local authorities and the Health and Safety Executive (HSE) can prosecute landlords who fail to arrange annual inspections. Penalties include fines of up to £6,000 per offence, and in cases involving tenant injury or death, imprisonment of up to 2 years. Beyond criminal penalties, non-compliance voids your landlord insurance. If a gas-related incident causes property damage, injury, or death and you do not hold a valid CP12, your insurer can refuse the claim entirely. This leaves you personally liable for all costs — which can run into hundreds of thousands of pounds. Letting agents are increasingly required to hold copies of valid gas safety certificates before marketing properties. Without current documentation, your property cannot be listed, tenants cannot be moved in, and void periods extend — costing you rental income. Carbon monoxide poisoning from faulty gas appliances remains a serious risk in rental properties. As a landlord, you have a legal and moral duty to ensure your tenants are safe. An annual gas safety check is the single most effective way to prevent gas-related incidents in your property. Our Process ## How It Works 1 ### Book Your Inspection Contact us with your property details. We schedule a convenient time and can coordinate directly with your tenants or letting agent. 2 ### Appliance Inspection Our Gas Safe registered engineer inspects every gas appliance in the property — checking for leaks, correct combustion, safe flue operation, and adequate ventilation. 3 ### Pipework & Flue Check We inspect all visible gas pipework for corrosion or damage and test flues for safe discharge of combustion products. 4 ### Issue CP12 Certificate If all appliances pass, we issue your Gas Safety Record (CP12) immediately. You receive both a digital and physical copy for your records. 5 ### Remedial Work (If Needed) If we identify any faults, we classify them as At Risk (AR), Immediately Dangerous (ID), or Not to Current Standards (NCS). We provide a fixed-price quote for any remedial work required. Benefits ## Why This Matters ### Full Legal Compliance Every inspection meets the requirements of the Gas Safety (Installation and Use) Regulations 1998. Your CP12 is legally valid documentation. ### Fast Turnaround Certificates issued same-day. We can schedule inspections within 24–48 hours and accommodate tenant availability. ### Multi-Property Discounts Manage multiple rental properties? We offer discounted rates for portfolio landlords and letting agents. ### Reminder Service We track your renewal dates and send reminders before your certificate expires — so you never miss a deadline. ### Combined Service Visits Save time and money by combining your gas safety check with an annual boiler service in a single visit. ### Tenant Coordination We liaise directly with tenants or letting agents to arrange access — removing the burden from you. ## What We Inspect During a Gas Safety Check The inspection covers every gas appliance provided by the landlord in the property. For gas boilers, we check the burner operation, gas pressure, flue integrity, ventilation, and safety devices. We perform a flue gas analysis to measure carbon monoxide and carbon dioxide levels, ensuring combustion is within safe parameters. For gas fires (both open-flue and balanced-flue types), we inspect the firebox, check the flue draught, test the gas supply for leaks, and verify that the appliance is correctly sealed and ventilated. We also check that fire surrounds and hearths meet safety clearance requirements. Gas cookers and hobs are tested for stable flame, correct gas pressure, and secure connection. We check the flame failure device (FFD) operation — a safety feature that cuts the gas supply if the flame goes out. We also verify that the cooker is correctly positioned with adequate clearance from walls and combustible surfaces. Gas pipework is inspected for visible damage, corrosion, and gas tightness. We check all accessible joints and connections for leaks using a gas leak detector. We also verify that the gas meter, emergency control valve, and isolation points are accessible and operational. Flues and chimneys are tested for correct draught and safe discharge of combustion products. Room-sealed appliances (balanced flue) are checked for external terminal condition, correct positioning, and freedom from obstruction. Open-flue appliances require additional ventilation checks to ensure adequate air supply for combustion. If we identify any faults, they are classified according to Gas Safe standards: Immediately Dangerous (ID) — the appliance is turned off and capped; At Risk (AR) — the appliance is safe to use temporarily but requires repair; Not to Current Standards (NCS) — the appliance does not meet current regulations but is not immediately dangerous. You receive a clear report with our findings and fixed-price repair quotes. FAQ ## Frequently Asked Questions How much does a landlord gas safety certificate cost in Barry?
