How Often Should My Business Have an Electrical Inspection?

Regular electrical inspections are critical for ensuring the safety of your employees, customers, and premises. But how often should they actually be carried out? In the UK, the answer depends on the type of business you operate, the condition of your installation, and legal compliance requirements — especially under health and safety legislation.

Here’s what every business owner, facilities manager, and landlord needs to know.

A commercial Electrical Installation Condition Report (EICR) is a formal assessment of a building’s fixed electrical wiring and systems. It’s carried out by a qualified electrician and checks the safety and integrity of:

• Distribution boards and consumer units
• Wiring, sockets, and switches
• Earthing and bonding
• Lighting and power circuits
• Emergency systems (e.g., lighting, alarms)

While there’s no one-size-fits-all law stating exact intervals, businesses have a legal duty under:

• The Electricity at Work Regulations 1989
• Health and Safety at Work Act 1974

These require that electrical systems are maintained in a safe condition at all times. A periodic inspection and EICR is the only recognised way to verify this compliance.

⚠️ Failure to comply can result in enforcement notices, prosecution, invalidated insurance, or even closure in serious cases.

Here are standard recommended frequencies (based on BS 7671:2018+A2:2022 and IET Guidance Notes):

Type of Premises	Recommended EICR Frequency
Offices	Every 5 years
Shops and retail units	Every 5 years
Restaurants and hotels	Every 5 years
Industrial installations	Every 3 years
Educational establishments	Every 5 years
Theatres and places of public entertainment	Every 3 years
Construction sites	Every 3 months
Licensed premises (e.g. pubs, clubs)	Every 1 year

👉 Note: More frequent inspections may be needed in environments that are damp, dusty, high-use, or subject to heavy wear.

Yes — it’s good practice to carry out routine visual inspections between full EICRs, typically:

• Annually, or more often in high-risk environments
• To check for signs of damage, overheating, exposed wiring, or overloaded sockets

A competent in-house facilities team can often carry this out, but findings should be logged and acted upon.

The report will classify observations using codes:

• C1 – Danger present (urgent action required)
• C2 – Potentially dangerous (needs improvement)
• C3 – Improvement recommended
• FI – Further investigation required

A Satisfactory EICR is needed for compliance. If the result is Unsatisfactory, remedial work must be completed and documented.

Only a qualified and registered electrician can issue an EICR. Make sure they are certified by bodies such as:

• NICEIC
• NAPIT
• ELECSA
• Stroma
