How Often Does a Commercial Property Need an EICR?

Quick Answer: Common EICR Intervals

Most people want a simple number like “every 5 years”. But there’s no one-size-fits-all answer in the UK. The correct approach is:

• No fixed legal interval for all commercial premises.
• A legal duty to maintain systems in a safe condition.
• The interval for inspection and testing, commonly called an EICR (Fixed Wire Testing), should be based on risk, condition, usage, and competent advice.

HSE guidance confirms there’s no mandatory test frequency, but electrical systems must be maintained to prevent danger. The EICR becomes your way of proving that you’re doing just that.

Most commercial property owners are advised to carry out an EICR / Fixed Wire Test every 5 years, but this is only a starting point. Shorter intervals may be needed depending on:

• The site environment (e.g. heat, dust, moisture)
• The building use and electrical load
• Any history of faults or known issues
• Insurer, landlord, or licensing requirements

The key is to set (and review) the interval based on competent guidance, not just the calendar.

What Is an EICR / Fixed Wire Test?

EICR stands for Electrical Installation Condition Report. It’s the formal record of periodic inspection and testing of a building’s fixed electrical wiring.

In everyday language, this is often called Fixed Wire Testing, especially by facilities teams and insurers. The terms are used interchangeably in most commercial settings.

The report helps you:

• Identify damage, deterioration or non-compliant work.
• Prioritise remedials based on risk (C1, C2, C3 codes).
• Provide evidence to clients, insurers or auditors that your installation is safe.

It does not guarantee zero faults, but it demonstrates due diligence and provides a documented action plan for identified risks.

Is an EICR / Fixed Wire Test Legally Required?

Not in those exact words, but yes, the legal obligation to maintain safety requires periodic inspection.

• The Electricity at Work Regulations require systems to be maintained to prevent danger.
• BS 7671 and NICEIC guidance are the recognised standards for interpreting that duty.
• An EICR / Fixed Wire Test is the recognised way to demonstrate compliance.

In short, it’s not about the paperwork; it’s about being able to prove that your building’s electrics are safe and managed.

How Often Should You Get an EICR?

As mentioned above, there’s no universal answer. The interval must be set based on:

• The type of premises
• How it’s used
• The level of maintenance
• Any external risks (e.g. vibration, moisture, risk of damage)

Common inspection intervals (guidance only)

• Offices, shops, standard commercial: every 5 years
• Public buildings, schools, leisure: every 5 years
• Warehouses or high-load commercial: often 3 years
• High-risk areas (wet, high footfall, sensitive use): sometimes 1 year

This is why competent advice matters-your next EICR date should reflect your site’s real conditions, not guesswork.

When Should You Bring an EICR Forward?

Even if your last EICR says “next test in 5 years”, you may need to bring it forward if anything changes. Typical triggers:

1. Change of tenant or occupancy
   – Different loads, layouts or uses can shift the risk profile.
2. Change of building use
   – Office to retail, or retail to food prep, introduces new compliance needs.
3. Electrical modifications
   – Added circuits, distribution changes, or major load increases.
4. Repeat faults or failures
   – Ongoing tripping, overheating or signs of damage.
5. Incident or damage
   – Fire, flooding, impact, rodent damage or water ingress.
6. Licensing or insurer requirements
   – Many commercial premises must show recent EICR evidence to comply.
   
   

Who Is Responsible for Arranging the EICR?

Responsibility depends on who controls the electrical system. In general:

• Landlords or managing agents: common areas and landlord-owned systems
• Tenants or occupiers: systems under their control
• FM companies or duty holders: usually coordinate testing for the whole site

What matters is that someone has clear responsibility—and the best way to manage that is to keep an up-to-date electrical compliance file, which includes:

• Latest EICR / Fixed Wire Test results
• Records of remedials or modifications
• Board schedules and asset details
• Maintenance records and fault history
  
  

What Happens During an EICR / Fixed Wire Test?

The inspection typically involves:

• Visual inspection of cabling, accessories and enclosures
• Dead and live testing (subject to safe isolation)
• Verifying protective devices and disconnection times
• Confirming earthing and bonding arrangements
• Documenting any observations with a risk code

Codes used on an EICR:

• C1: Danger present – immediate action required
• C2: Potential danger – urgent action recommended
• C3: Improvement advised
• FI: Further investigation needed

The outcome is a prioritised action plan. It’s not just about “pass” or “fail”, it’s about knowing where you stand and what to do next.

How to Plan a Commercial EICR Without Disruption

Planning is 80% of the job. Here’s how to keep it smooth:

Step 1: Gather documents

• Previous EICR
• Circuit schedules, layouts, and access notes
• Details of any areas with restricted access

Step 2: Identify critical areas

• Server rooms, life safety systems, refrigeration
• Areas that can’t lose power without notice

Step 3: Agree on shutdown windows

• Out-of-hours or phased zones if needed
• Permits or access arrangements

Step 4: Agree on the success criteria

• What will be tested
• What access is assumed
• What constitutes “completion”

Step 5: Plan remedials in advance

Where issues are likely, pre-agree a path for pricing and scheduling remedial works.

Does Planned Maintenance Affect EICR Frequency?

Yes. If you run a planned electrical maintenance programme, you may justify longer intervals between full EICRs because:

• You’re monitoring asset condition continuously
• Issues are caught and fixed earlier
• Records prove the system is under control

That said, nothing replaces periodic testing. But good maintenance improves your EICR results and often makes them cheaper to resolve.

What to Include in Your EICR Compliance File

For audit, landlord, or insurer purposes, build a simple compliance file:

• Current EICR report
• Remedial records and completion certs
• Distribution board schedules and labels
• Maintenance logs (planned and reactive)
• Notes on known constraints or risks

This means you’re ready when someone asks:

• When was the last test?
• What was found and fixed?
• What’s the next due date and why?
  
  

When a “5-Year EICR” Isn’t Enough

Even a perfect EICR becomes out of date when:

• The use of the site changes
• Faults start to reappear
• There’s damage or wear not covered by the last test
• Licensing or insurance rules change

This is why the real rule is: maintain your installation in a safe condition, and test often enough to prove it. Visit our main page for more information on how we can help.

FAQs: EICR / Fixed Wire Testing for Commercial Premises

Is an EICR legally required for commercial buildings?

Yes, in practice. The law requires you to maintain systems safely. An EICR (Fixed Wire Test) is the accepted way to prove this.

How often is fixed wire testing required?

Usually every 5 years for low-risk commercial buildings—but shorter intervals may apply depending on use, environment, and inspection results.

Is “Fixed Wire Testing” the same as an EICR?

Yes. “Fixed Wire Testing” is the common term, but the official report is called an EICR (Electrical Installation Condition Report).

Who should carry it out?

A competent, qualified person with suitable experience. EICRs should not be performed by general electricians unless they are trained in inspection and testing.

What do the EICR codes mean?

• C1: Immediate danger – act now
• C2: Potential danger – fix soon
• C3: Improvement advised
• FI: Further investigation required
