Faulty electrical installations cause hundreds of fires in UK commercial premises every year, many of which could have been prevented with proper testing. Fixed wire testing, also known as an Electrical Installation Condition Report (EICR), is your frontline defence against electrical hazards—and it’s a legal requirement for business owners and landlords.
But who’s qualified to carry out this critical safety check, and how often does your business need one?
Only Qualified Electricians Can Perform Fixed Wire Testing
Fixed wire testing must always be carried out by a qualified and competent commercial electrician with the appropriate certifications and experience. The electrician should hold recognised qualifications such as City & Guilds 2391 (Inspection and Testing) or equivalent, and have a strong understanding of BS 7671 wiring regulations.
This isn’t a job for general maintenance staff or unlicensed contractors. Commercial electrical systems are complex and potentially dangerous. Only a competent person can safely assess their condition and issue a valid EICR certificate that satisfies legal requirements.
Legal Responsibilities for Business Owners
Under the Electricity at Work Regulations 1989, employers, landlords and duty holders are legally required to ensure electrical installations are maintained in a safe condition. A fixed wire test is the recognised way to demonstrate compliance.
In most commercial settings, this testing should be carried out every five years. However, higher-risk environments need more frequent inspections—typically every three years or even annually. These include:
- Gyms and leisure centres – where moisture and heavy equipment create additional electrical risks
- Restaurants and commercial kitchens – due to heat, water and intensive equipment use
- Factories and industrial sites – where machinery and harsh conditions accelerate wear and tear
Failing to complete or renew your EICR could:
- Invalidate your insurance policy
- Lead to fines or prosecution from the HSE
- Put staff and visitors at risk of electrical shock or fire
What’s Involved in Fixed Wire Testing
A comprehensive EICR inspection typically takes several hours, depending on the size of your premises. Your commercial electrician will thoroughly examine your entire electrical installation to identify any safety issues or deterioration.
During a test, the electrician will:
- Visually inspect all electrical systems and connections
- Test circuits, distribution boards and outlets for safety and performance
- Identify any deterioration, damage or non-compliance
- Provide a detailed report outlining remedial actions (if required)
Once complete, you’ll receive an official EICR certificate confirming your installation’s condition. The report will classify any issues found using a coding system: C1 (danger present, immediate action required), C2 (potentially dangerous, urgent remediation needed), or C3 (improvement recommended). Your electrician will explain what these mean for your business and help prioritise any necessary work.
