Frequently asked questions
How often must a gas safety check be done?
Every 12 months by a Gas Safe registered engineer, covering all gas appliances, flues and pipework in a let property.
When must the record be given to tenants?
Existing tenants within 28 days of the check; new tenants before they move in. Keep records for two years.
What if the tenant won't grant access?
Make and keep written records of every reasonable attempt to gain access — that evidence protects you if the anniversary is missed through no fault of your own.
