Your Legal Obligations

What the law requires
of every landlord

Gas Safety Regulations — Important

Failure to hold a valid CP12 is a criminal offence

Under the Gas Safety (Installation and Use) Regulations 1998, all landlords must ensure gas appliances are inspected annually by a Gas Safe registered engineer. Failure to comply can result in criminal prosecution, unlimited fines, custodial sentences, invalidated insurance and the inability to serve a valid Section 21 notice.

needs in one place
