Commercial EICR & Electrical Compliance: The UK Guide for Property Managers
If a fire investigator traced the cause back to faulty wiring at one of your sites, would you be able to produce a valid Electrical Installation Condition Report on demand?
For most commercial property managers, that question creates a moment of pause. Electrical compliance sits across multiple regulations, the testing language is technical, and the consequences of getting it wrong range from voided insurance to criminal prosecution.
This guide covers what an EICR is, who is legally responsible for commercial premises, how often each electrical test should happen, and what the result codes actually mean. Whether you manage a single retail unit or a 200-site portfolio, you will come away knowing what compliant looks like.
What is an EICR?
An Electrical Installation Condition Report (EICR) is a formal assessment of the fixed electrical installation in a property, including the wiring, sockets, distribution boards, switches, and consumer units. It is carried out by a qualified electrical engineer and reports the condition of the installation against the current edition of BS 7671 (the IET Wiring Regulations).
The point of an EICR is to identify deterioration, defects, and dangerous conditions before they cause harm. For commercial property, EICRs serve three purposes:
- Legal compliance under the Electricity at Work Regulations 1989.
- Insurance compliance, as most commercial property policies require valid certification.
- Lease compliance, as commercial leases routinely require certification to be kept current.
Who is responsible?
In commercial premises, responsibility falls on the duty holder, defined under the Electricity at Work Regulations 1989 as anyone in control of an electrical system at a workplace. Depending on the lease structure, this can be the building owner, the tenant, a managing agent, or the employer.
On full repairing and insuring (FRI) leases, the tenant is usually the duty holder. On internal repairing leases, responsibility often splits between landlord and tenant. In multi-let buildings, the landlord typically covers common parts while tenants cover their demise. If you are unsure who is responsible at a site, the lease is the starting point, but err on the side of getting the inspection done.
Commercial compliance frequencies at a glance
| Inspection | Recommended Frequency | Governing Document |
|---|---|---|
| EICR (Fixed Wire Testing) | Every 5 years, or on change of occupancy | IET Guidance Note 3, BS 7671 |
| PAT Testing | Risk-based, more frequent for high-use equipment | IET Code of Practice (5th edition) |
| Emergency Lighting Testing | Monthly functional, annual full-duration discharge | BS 5266 |
| Fire Alarm System Testing | Weekly user test, six-monthly engineer service | BS 5839 |
Some industries such as industrial sites, leisure venues, swimming pools and petrol stations require more frequent EICRs, typically every one to three years.
Understanding EICR result codes
When your EICR comes back, observations are listed against four standard codes:
- C1 (Danger present): Immediate risk of injury. Report marked Unsatisfactory.
- C2 (Potentially dangerous): Urgent remedial action required. Report marked Unsatisfactory.
- C3 (Improvement recommended): Not dangerous, but does not meet current standards. The report can still be satisfactory.
- FI (Further investigation): Something needs deeper inspection before a final classification can be given.
A Satisfactory EICR with C3 observations is normal and usually reflects older installations that met earlier wiring regulations. An Unsatisfactory EICR requires action, and continuing to operate a site with known C1 or C2 issues exposes the duty holder to serious liability.
What happens if you fail to comply?
The Health and Safety Executive can prosecute breaches of the Electricity at Work Regulations 1989, with penalties including unlimited fines and, in the most serious cases, custodial sentences for directors. More commonly, the consequences are commercial:
- Insurance void. An expired or missing EICR can result in claims being refused after an incident.
- Lease breach. Non-compliance can trigger landlord action or block sub-letting.
- Operational shutdown. A site found to be electrically unsafe can be closed by the local authority or an insurance assessor, costing thousands of pounds in lost trading per day.
Managing compliance across multiple sites
For property managers responsible for multiple buildings, the challenge is not the testing itself but the coordination. Different sites have different lease structures, last-inspection dates, and responsible parties.
The most common failure pattern is the patchwork model, where a different local contractor handles each site, certificates arrive in different formats and live in different places, and no central calendar tracks renewals. Compliance technically exists but cannot be evidenced quickly when needed. A unified approach, with a single contractor, centralised records, and proactive scheduling, is what proper planned preventative maintenance looks like in practice.
Where to go from here
At TMS Facilities Management, our Electrical & Compliance team carries out EICRs, PAT testing, fixed wire testing and emergency lighting inspections across commercial sites throughout the UK and Ireland. We hold all certification centrally and flag renewals before they expire, so multi-site portfolios stay compliant without anyone in your team having to chase paperwork.If you would like a review of your current electrical compliance schedule, get in touch with our team.
