It’s a legal requirement for landlords to have all gas appliances, pipework, chimneys and flues checked every 12 months to make sure the property they’re renting out is safe for their tenants.
Once this check has been completed, you will get a CP12 certificate. You’ll need to provide a copy to your tenants within 28 days and you’ll need to give one to new renters when they move in.
It’s really important that the check is only carried out by a Gas Safe registered engineer, or you won’t receive the proper legal certification.
If your tenants have brought any gas appliances with them, you are only responsible for the pipework that supplies them, but it’s worth including them in your annual check.
Please contact me if this is something that you require.
