How Long Does a Gas Safety Check Take?

09 October 2025

If you’re a homeowner, landlord, or tenant, a gas safety check is one of the most important steps you can take to ensure your home stays safe and compliant. But how long does a gas safety check actually take — and what happens during the inspection?

In this guide, the experts at Shropshire Gas explain how long a gas safety check typically takes, what’s included, and why it’s essential to have it carried out by a Gas Safe registered engineer.

What Is a Gas Safety Check?

A gas safety check is a professional inspection carried out by a Gas Safe registered engineer to ensure all gas appliances, pipework, and flues in your property are working safely and efficiently.

These checks are designed to identify:

  • Gas leaks or signs of corrosion

  • Faulty appliances or fittings

  • Inadequate ventilation

  • Dangerous levels of carbon monoxide

If you rent out a property, an annual gas safety check is a legal requirement, but it’s also recommended for homeowners to schedule one every 12 months for peace of mind.

How Long Does a Gas Safety Check Take?

The time it takes depends on the size of the property and the number of gas appliances being inspected.

As a general guide:

  • 1–2 appliances (e.g. boiler and gas hob): around 30–40 minutes

  • 3 or more appliances: up to 1 hour or slightly longer

For landlords managing multiple properties or large commercial premises, checks may take longer.

At Shropshire Gas, our experienced engineers work efficiently without cutting corners, ensuring every part of your system is properly tested and documented.

What’s Included in the Inspection?

A full gas safety check will typically include:

  • Visual inspection of all gas appliances and flues

  • Checking gas pipework for leaks

  • Testing burner pressure and gas rate

  • Ensuring appliances have adequate ventilation

  • Checking for signs of carbon monoxide

  • Inspecting seals, safety devices, and flame condition

  • Recording results in a Gas Safety Certificate (CP12)

If any issues are found, your engineer will explain them clearly and provide advice or a quote for any necessary repairs.

Do Landlords Need Annual Gas Safety Checks?

Yes — under the Gas Safety (Installation and Use) Regulations 1998, landlords are legally required to have a Gas Safety Check carried out every 12 months.

After the inspection, you’ll receive a Landlord Gas Safety Certificate (CP12), which must be provided to tenants within 28 days of the check (and before new tenants move in).

Failure to comply with these regulations can lead to fines or even prosecution, so it’s vital to stay up to date.

What Happens After the Check?

Once the inspection is complete:

  1. The engineer will explain any findings.

  2. You’ll receive your Gas Safety Certificate (CP12) — either digitally or on paper.

  3. Any recommended repairs or maintenance will be discussed.

If everything is in good working order, you can relax knowing your gas system is safe and compliant for another year.
