A Gas Safety Certificate — also known as a CP12 — confirms that your gas appliances, flues, and pipework have been inspected and found safe by a Certified Gas engineer. It’s a legal requirement for landlords in the UK and must be renewed every 12 months.
We inspect all major appliances, ensure compliance, and provide a digital certificate within hours of inspection.
Non-compliance can lead to heavy fines, insurance issues, and even criminal charges.
