It's a legal requirement under the Gas Safety (Installation and Use) Regulations 1998.
All landlords must have a CP12 inspection carried out every 12 months by a Gas Safe registered engineer. The certificate must be provided to existing tenants within 28 days and to new tenants before they move in. Failure to comply carries a fine of up to £6,000 per offence and can invalidate your landlord insurance.
