Gas Safety Certificates
CP12 - A Legal Requirement. Not an Optional Extra.
Gas Safety Certificate CP12 inspections for landlords across London by Gas Safe registered engineers.
A Gas Safety Certificate, commonly referred to as a CP12, is a legal requirement for landlords and must be renewed every 12 months. A Gas Safe registered engineer must carry out the inspection, and landlords are required to provide tenants with a copy of the certificate within 28 days of the check, or before the start of a new tenancy.
The purpose of the inspection is to confirm that all gas appliances, pipework, flues and ventilation within the property are operating safely. Failing to arrange a valid certificate can result in significant penalties and, more importantly, can put tenants at unnecessary risk.
At Berkley, our Gas Safe registered engineers carry out thorough and methodical gas safety inspections, checking each appliance and component carefully. Once the inspection is complete, we issue the official Gas Safety Certificate promptly, helping landlords, letting agents and property managers remain fully compliant while ensuring the property is safe for those living in it.
