Frequently Asked Questions
How often do I need a gas safety certificate?
Landlords must have a gas safety check carried out every 12 months on every gas appliance in rental properties. The check must be done by a Gas Safe registered engineer.
What is a CP12 certificate?
CP12 is the industry name for a Landlord Gas Safety Record. It confirms that all gas appliances and pipework in a property have been checked and are safe to use.
Do homeowners need a gas safety certificate?
It's not a legal requirement for homeowners, but we strongly recommend an annual gas safety check for your family's safety. Carbon monoxide from faulty appliances is a serious risk.
What happens if a gas appliance fails the safety check?
If an appliance is unsafe, we are legally required to disconnect it and label it 'Do Not Use'. We'll explain the issue and provide a quote for repair or replacement.
Can you do gas safety checks for multiple properties?
Yes, we offer discounts for landlords and letting agents with multiple properties. Contact us for a bulk rate.
