If you own or manage a commercial property in the UK, you might be wondering: do I need gas and electrical certificates in a commercial unit? The short answer is yes—most of the time, you do. But the exact requirements depend on a few key factors, like the type of business, the size of the premises, and whether or not tenants are involved.
Let’s break it down in plain English.
Gas Certificates for Commercial Properties
If your commercial unit has a gas supply or any gas appliances (like boilers, cookers or heaters), you’re legally required to ensure everything is safe and properly maintained.

Who needs a commercial gas safety certificate?
- Landlords of commercial units that are leased or rented out must arrange an annual gas safety check by a Gas Safe registered engineer.
- Business owners who operate on the premises and use gas equipment also need to get regular checks for compliance and insurance purposes.
The gas engineer will issue a CP42 or Commercial Gas Safety Certificate, depending on the nature of the appliances and system. It’s not just about staying legal—it’s about keeping staff, customers, and the public safe. Penalties for non-compliance? You could face heavy fines, and in serious cases, even prosecution if someone’s injured due to a gas fault.
Electrical Certificates – What’s Required?
All commercial properties in the UK must meet the Electricity at Work Regulations 1989, which means the electrical systems must be safe to use and regularly maintained.
What certificates should you have?
- EICR (Electrical Installation Condition Report) – This is the big one. It’s basically an MOT for the building’s electrics. You’ll need one every 5 years, or more often if specified by an electrician.
- EIC (Electrical Installation Certificate) – Issued after any major electrical installation or alteration.
If you’re a landlord, it’s your responsibility to provide a valid EICR before a new tenant moves in and ensure the system stays safe throughout the lease.
If you’re a business owner occupying the unit, you’re still responsible for keeping the electrics in working order and safe for use, even if you don’t own the building.

Insurance and Legal Considerations
Most commercial insurance policies will ask for up-to-date gas and electrical safety certificates. If you don’t have them, your cover could be void if anything goes wrong. Also, health and safety inspections—especially from local councils or fire services—often require proof that your installations are up to standard.
The Bottom Line
So, back to the original question: do I need gas and electrical certificates in a commercial unit? Yes, in nearly all cases. Whether you’re a landlord or running your own business, you have a legal duty to make sure your gas and electrical systems are safe, inspected, and documented. Regular checks not only keep you on the right side of the law—they also protect your business, your staff, and anyone entering the property. If you’re unsure, speak to a qualified Gas Safe engineer or a registered electrician. It’s always better to be safe (and legal) than sorry.

FAQs
Yes, if your commercial premises have gas appliances or installations, you’re legally obliged to have a valid Gas Safety Certificate. This applies to landlords and business owners alike. The certificate must be renewed every 12 months and issued by a Gas Safe registered engineer.
Depending on your setup, you might need one of the following:
> CP15 – Commercial Boiler Gas Safety Certificate
> CP16 – Gas Installation Testing and Purging
> CP17 – Gas Installation Safety Report (Non-domestic)
> CP42 – Commercial Catering Gas Safety Certificate (for kitchens)
These ensure that specific systems or appliances meet safety standards.

Operating without one can lead to serious consequences, including:
> Fines or prosecution
> Invalidated insurance policies
> Potential closure of your business
> Increased risk of accidents or carbon monoxide leaks
It’s not just a legal requirement—it’s a vital safety measure.
While not explicitly mandated by law, having an EICR is strongly advised. It demonstrates compliance with the Health and Safety at Work Act 1974 and the Electricity at Work Regulations 1989, ensuring your electrical installations are safe.
Typically, every five years. However, the frequency can vary based on the property’s usage and condition. Regular inspections help identify potential hazards and maintain safety standards.
Responsibility can vary based on lease agreements:
– Landlords are generally responsible for ensuring the property meets safety standards before leasing.
– Tenants may be responsible for ongoing maintenance and obtaining certificates during their tenancy.
Always refer to your lease to determine specific obligations.
The Gas Safe Register is the UK’s official list of gas engineers qualified to work safely and legally on gas appliances.Only engineers listed here can issue valid Gas Safety Certificates.
While not having an EICR isn’t a direct legal offence, failing to ensure electrical safety can lead to:
> Fines
> Invalidated insurance claims
> Legal action in the event of accidents
An EICR helps demonstrate due diligence in maintaining electrical safety.
For gas inspections, use the Gas Safe Register to find certified engineers. For electrical inspections, look for electricians registered with bodies like NICEIC or NAPIT.
