What Is a Gas Safety Certificate?
A Gas Safety Certificate (CP12) is an official document issued by a Gas Safe registered engineer after a thorough inspection of your property’s gas appliances, pipework, and ventilation systems.
Who Needs One?
🏠 Landlords – Legally required to have an annual gas safety check.
🏢 Business Owners – Essential for commercial kitchens, hotels, and offices.
🏡 Homeowners – Not required by law, but highly recommended for safety and efficiency.
What’s Checked During a Gas Safety Inspection?
✅ Gas appliances (boilers, cookers, fires)
✅ Flues, chimneys, and ventilation
✅ Gas pipework for leaks or damage
✅ Carbon monoxide levels
A Gas Safety Certificate is valid for 12 months, meaning landlords and businesses must renew it annually.
