If you run a business or own commercial property in the UK, understanding gas safety responsibilities is not something you can afford to overlook. One question that often crops up is: who is responsible for the gas safety certificate in commercial premises?
The answer depends on the setup of the property – but there are clear rules in place, and they matter for legal and safety reasons.
The Legal Requirement
Gas safety in commercial settings falls under the Gas Safety (Installation and Use) Regulations 1998. If your premises have gas appliances or pipework, you must ensure they are maintained properly and checked regularly.
This isn’t just about ticking a box – faulty gas systems can lead to serious risks, from carbon monoxide leaks to fires and explosions.

So, Who Is Actually Responsible?
Generally, the duty lies with whoever controls the property or the gas appliances. Here’s how it usually breaks down:
Commercial Landlords
If you’re a landlord letting out a commercial unit with gas appliances, you are responsible for making sure a valid gas safety certificate is in place. This includes annual checks by a Gas Safe registered engineer.
Even if the lease says the tenant takes care of maintenance, the legal obligation often still rests with the landlord unless it’s very clearly written otherwise.
Business Tenants
In some cases, tenants may be responsible – especially if they’ve installed their own gas appliances or the lease agreement clearly shifts responsibility to them. If you’re renting and unsure, check your lease carefully.
If you’re a tenant running a café, restaurant, shop or office with gas systems you installed, the responsibility is likely yours.
Managing Agents
If a managing agent is employed to look after the property, they may organise the checks – but the legal responsibility still sits with the landlord or tenant, depending on the terms of the lease.

What Does a Commercial Gas Safety Certificate Involve?
A commercial gas safety certificate (often referred to as a CP42 or CP12 for commercial kitchens) includes a full inspection of:
- Gas appliances
- Pipework
- Flues
- Ventilation
The engineer will issue a certificate if everything is safe. If something’s not right, they’ll explain what needs to be fixed before the certificate can be issued.
Don’t Confuse Domestic with Commercial
Commercial gas safety checks are more complex than domestic ones. The engineer must hold the right commercial qualifications, so always check they’re Gas Safe registered and listed for commercial work.
The Bottom Line
So, who is responsible for gas safety certificate in commercial properties? In short: it depends, but usually it’s the landlord or the tenant, depending on how the lease is set up and who owns or installs the gas appliances.
Either way, the key thing is that someone is clearly responsible – and the checks are done every 12 months by a qualified professional. Not only is it the law, but it keeps everyone safe.
If you’re unsure who holds the responsibility in your case, speak to a solicitor or property professional. It’s far better to be clear than to assume.
FAQs
Yes, if the property has gas appliances, pipework or installations. It’s a legal requirement to have them checked at least once a year by a Gas Safe registered engineer.
It depends on the lease agreement. In many cases, the landlord pays, especially if the gas appliances came with the property. But if the tenant installed the equipment or the lease clearly says it’s their job, then the tenant might be responsible.
If regular gas safety checks aren’t carried out, the responsible party could face fines or legal action. More importantly, it puts people at serious risk. Insurance might also be invalid if there’s an incident and checks weren’t done.
Legally, a gas safety check is required every 12 months. However, depending on usage and manufacturer guidelines, some appliances may need more frequent servicing for safety and efficiency.
No – the engineer must be qualified specifically for commercial gas work. Always check their Gas Safe ID and make sure they’re listed for commercial inspections, not just domestic ones.
If the office has gas appliances – like a boiler or kitchen equipment – then yes, it needs an annual gas safety check. If there’s no gas on-site, then no certificate is required.
The engineer will check all gas appliances, pipework, flues and ventilation. They’ll also test for leaks and ensure everything meets safety standards. If it passes, they’ll issue the certificate on the spot.
You’re not legally covered. The property is considered non-compliant, and any gas-related incident could lead to legal consequences. Make sure checks are done annually without fail.
