What Is A Gas Safety Certificate?

A commercial gas safety certificate, sometimes referred to as a gas safety record or a CP12, is a legal document that informs regulatory bodies that all gas appliances have been checked by a qualified and experienced engineer.

To ensure your appliances are safe for you and your employees, an annually scheduled gas safety check done by a registered engineer, could highlight if there are any concerns to be fixed, avoiding any potential lawsuits and pre-empting costly repairs if caught sooner.

Do I Need A Gas Safety Certificate?

It is a legal requirement to schedule regular gas safety checks and have an up-to-date gas safety certificate. Failure to do so will subject you to hefty fines and potential imprisonment. Aside from business gas appliances being unsafe, they can also cost you a large lump sum to repair if left unchecked.

Anyone who is responsible for a commercial premise or those who own one must test their appliances at least once a year. By booking a registered gas engineer to perform these checks and certify the safety of your property, you can ensure the safety of you and your employees and avoid any fines or imprisonment.

Do I Need To Do A Gas Safety Check?

In short, yes. Ensuring a gas safety check is done every year on all appliances is not only a legal requirement but failing to receive a gas safety certificate will likely invalidate your insurance.

If you’re a landlord and you fail to do regular gas safety checks, you won't be able to use section 21 in your policy should you need to evict a tenant as your insurance is likely to be invalid. Regularly scheduled gas safety checks not only protect your tenants and employees but it will also protect you as a business to avoid costly fines and potential imprisonment.

What Does A Gas Safety Check Involve?

Once you’ve booked in with a registered gas-safe engineer, they will typically check any gas appliance on the premises. This includes fireplaces, boilers, cookers, ovens, hand boilers, space heaters, and water heaters.

The gas-safe engineer will also inspect for any blocks in flues and chimneys to make sure they are safe to use.

What Is The Gas Safe Register?

The Gas Safe Register is the official gas registration body of gas engineers and businesses in the UK, Isle of Man, Guernsey, and Jersey.

The register is a list of businesses that are qualified and legally allowed to carry out any type of gas work under the trading name they are registered with. By law, all gas businesses must be on the Gas Safe Register.

What Should A Commercial Gas Safety Certificate Look Like?

After your gas safety check, you will receive a gas safety certificate that includes the name of the registered engineer who performed the tests, their registration number and their signature. The date the checks were carried out and the address of the property where the tests took place.

It will also include a description and location of each appliance checked, all passes and failures and if anything needs attention.

What If I Have A Gas Safety Fault?

If you have any concerns about your gas appliances, either in your home or in your business, do not use them and call out a registered gas-safe engineer as soon as possible to check.

If the gas-safe engineer disconnects any appliance, you should not reconnect any until the fault has been cleared as safe. Failure to follow this rule is against the law and there could be serious repercussions.

What If I Fail The Gas Safety Check?

Before using any equipment again, you must make sure it is safe for you or your employees to use. You must replace or repair any appliance with a gas-safe engineer, who will give you a record of any fixes.

By keeping copies of any work carried out by a gas-safe registered engineer, you can at least have the confidence and the proof that your appliances are once again safe to use.
