When it comes to gas safety, misinformation can be just as dangerous as neglect. Tenants and landlords alike are often misled by persistent myths surrounding gas safety checks, certificates, and who’s qualified to carry out inspections.

In this post, we debunk some of the most common gas safety myths, explain the facts clearly, and answer questions many people are too afraid to ask.

Myth 1: All Plumbers Are Gas Safe Registered

False. Not every plumber is qualified to work on gas appliances.

Only engineers listed on the Gas Safe Register are legally allowed to carry out gas work in the UK. This includes annual gas safety checks, servicing, and installations. Just because someone is a skilled plumber doesn’t mean they’re authorised to work with gas.

How to check: Always ask to see the engineer’s Gas Safe ID card or verify them at GasSafeRegister.co.uk.

Myth 2: Gas Safety Certificates Last for Two Years

Incorrect. A Gas Safety Certificate (CP12) is valid for 12 months only.

Landlords are legally required to carry out a gas safety check every year and provide a copy of the certificate to the tenant within 28 days of the check.

Letting a certificate lapse, even by a few days, puts both the landlord and tenant at risk.

Myth 3: Gas Safety Checks Are Only Needed When Something Goes Wrong

Wrong. Gas safety checks are preventative, not just reactive.

Even if everything seems to be working fine, faults may be hidden. Gas leaks, carbon monoxide risks, or appliance malfunctions can develop slowly over time. Annual checks help catch these problems early, before they become dangerous.

Myth 4: Tenants Are Responsible for Booking Gas Safety Checks

Not true. The responsibility lies with the landlord, not the tenant.

Landlords must arrange the annual check and provide a Gas Safety Certificate. However, tenants do have a role: they must allow reasonable access for the engineer to complete the inspection.

Myth 5: New Appliances Don’t Need to Be Checked

Misleading. Even new gas appliances can pose risks if not properly installed or ventilated.

If a landlord installs a new boiler, for example, they should still have it checked by a Gas Safe engineer to confirm it’s working safely, and continue including it in the annual inspection going forward.

Myth 6: Gas Safety Checks Take a Long Time or Are Disruptive

Generally false. Most standard gas safety checks take 30 to 60 minutes.

The engineer will inspect the boiler, cooker, and any other fixed gas appliances provided by the landlord. In most cases, the process is simple, unobtrusive, and well worth the peace of mind it provides.

One Last Thing

Misinformation can cause delays, missed checks, and serious safety risks. By understanding and challenging gas safety myths, tenants and landlords alike can stay safe and legally compliant.

If you’re ever unsure, check the Gas Safe Register or speak to a trusted housing advisor. With gas, it’s always better to ask questions than make assumptions.
