Commercial EICR Frequency: How Often You Need One
Last updated: 13 October 2026
Priority First notes that a commercial building needs an EICR (Electrical Installation Condition Report) at intervals set by the property type: offices, shops and similar premises require one every five years, industrial units every three years, construction sites every three months, and leisure complexes or swimming pools every year, under IET Guidance Note 3 and BS 7671.
Key Takeaways
- Offices, shops and similar commercial premises need an EICR at least every five years, per Elsys Electrical / IET Wiring Regulations (BS 7671) guidance.
- Priority First highlights that industrial premises require a shorter maximum interval of three years between inspections, per BES Group.
- Priority First points out that construction sites carry the shortest recommended interval of any premises type, at three months, per Norm Electric.
- Leisure complexes and swimming pools need annual EICR inspections, a maximum one-year interval, per Norm Electric.
- The Electricity at Work Regulations 1989 make maintaining a safe electrical installation a legal duty, even though it does not name the EICR document itself.
What Is an EICR and What Does It Check?
An EICR, or Electrical Installation Condition Report, is a formal inspection and testing document that assesses the safety of a building's fixed electrical installation against the UK wiring standard, BS 7671. A qualified electrician examines wiring, distribution boards, circuit protection, earthing and bonding arrangements, then records any damage, deterioration, defects or non-compliance with current regulations.
The inspection does not cover portable appliances such as kettles or laptop chargers — that falls under separate portable appliance testing (PAT). An EICR instead focuses on the fixed infrastructure: the cables behind the walls, the consumer units, the sockets fixed to the structure, and the earthing that protects people from electric shock.
The report issues a pass or fail outcome, supported by observation codes explained later in this article. Every EICR carries a "next inspection due" date, which is the practical answer most building managers are actually looking for.
What Is the Standard Recommended EICR Frequency for a Commercial Building?
The standard recommended frequency for a commercial EICR is set out in IET Guidance Note 3, which ties the maximum interval to the type of installation and how hard it works. Recommended EICR intervals for commercial premises range from every three months for construction site installations to up to five years for offices, shops and similar premises, according to BES Group.
This is a maximum, not a target. A qualified inspector can — and often does — recommend a shorter interval where an installation shows signs of wear, has a history of faults, or operates in a demanding environment such as a commercial kitchen or a plant room with high humidity.
Five years is the default assumption most office landlords and tenants work to, but it is a ceiling that assumes the installation is in good condition at the last inspection. Priority First's own building management teams treat the EICR due date as one entry in a wider annual compliance calendar, alongside fire alarm servicing, emergency lighting checks and fixed wire testing — a scheduling approach set out in Priority First's guide, Building Manager's Annual Compliance Calendar.
Does EICR Frequency Change by Commercial Property Type?
EICR frequency changes significantly by property type, because risk, usage intensity and environmental stress on wiring vary enormously between an office and a factory floor. The table below sets out the maximum recommended interval for common commercial categories.
| Premises type | Maximum recommended EICR interval | Source |
|---|---|---|
| Offices, shops, laboratories | 5 years | Elsys Electrical |
| Industrial premises | 3 years | BES Group |
| Leisure complexes and swimming pools | 1 year | Norm Electric |
| Construction sites | 3 months | Norm Electric |
| Private rented residential (for comparison) | 5 years, plus before every new tenancy | Electrical Testing London |
Industrial premises require a shorter cycle than general offices because heavier machinery, higher loads and harsher environments accelerate cable and connection wear. IET Guidance Note 3 recommends a maximum initial interval of three years for industrial installations, compared with five years for general commercial installations, according to BES Group.
Mixed-use buildings — a common pattern in central London, where ground-floor retail sits beneath residential or office floors — need separate consideration for each installation type rather than a single blanket interval. A warehouse with a small admin office attached typically needs the industrial three-year cycle applied to the warehouse circuits, even if the office area alone would only need five years.
Is a Commercial EICR a Legal Requirement Under UK Law?
A commercial EICR is not named explicitly as mandatory in UK statute, but the underlying legal duty to maintain electrical safety absolutely is. The Electricity at Work Regulations 1989 (SI 1989/635), enforced by the Health and Safety Executive, require every employer and building duty holder to ensure electrical systems are constructed, maintained and used so as to prevent danger.
The regulations do not say "get an EICR every five years" in so many words. The HSE's own guidance document, HSR25 — Memorandum of Guidance on the Electricity at Work Regulations 1989, points businesses toward BS 7671 and periodic inspection as the recognised method of demonstrating compliance.
In practice, that makes an EICR the standard evidence a duty holder produces if the HSE, an insurer, or a fire investigator ever asks how electrical risk was managed. The Health and Safety at Work etc. Act 1974 sits above the 1989 regulations as the general duty of care, and most commercial insurance policies now make a valid, in-date EICR a condition of cover rather than a courtesy.
Who Is Responsible for Arranging a Commercial EICR — Landlord or Tenant?
Responsibility for arranging a commercial EICR depends on the lease, but the Electricity at Work Regulations 1989 place the underlying legal duty on whoever controls the electrical installation. In a single-let building, that is usually the tenant for the installation within their demise and the landlord for communal areas such as plant rooms, lift motor rooms and shared risers.
Multi-tenant commercial buildings often split this further, which is where confusion creeps in. A typical full repairing and insuring (FRI) lease pushes EICR responsibility for the demised space onto the tenant, while the landlord retains responsibility for the base building supply and common parts.
Priority First advises that whoever holds the legal duty, the practical answer is the same: someone named in writing must own the EICR schedule, the inspector's report, and the remediation of any faults found. Priority First's facilities management teams typically hold this schedule on behalf of landlords across prime central London portfolios, so that no single floor or unit falls through the gap between a landlord's compliance calendar and a tenant's lease obligations.
What Happens If a Commercial EICR Is Overdue or Never Carried Out?
An overdue commercial EICR exposes a business to enforcement action, insurance invalidation and, in the event of a fire or electric shock incident, potential prosecution under the Electricity at Work Regulations 1989. The Health and Safety Executive can investigate any material breach of health and safety law, including electrical safety failures, and recover its costs directly from the business under its Fee for Intervention scheme.
The HSE Fee for Intervention (FFI) hourly rate for investigating material breaches of health and safety law, including electrical safety failures, is £183 per hour as of 2026, according to Weightmans / HSE. That rate applies from the moment an inspector identifies a breach, not from the point of any formal notice.
The scale of this is not hypothetical. The HSE recovered £4.5 million through its Fee for Intervention scheme in 2026/25, charging 5,143 businesses an average of £875 per business for health and safety breaches, per InstallerSHOW. Priority First notes that beyond HSE cost recovery, most commercial buildings insurance policies require a current, satisfactory EICR; an overdue or failed report can give an insurer grounds to decline a claim after a fire or an electrical fault.
What Do EICR Codes Mean and What Happens When Issues Are Found?
Priority First explains that EICR observation codes classify every defect an inspector finds by severity, and they determine how urgently the fault must be fixed. There are four codes: C1, C2, C3 and FI.
- For C1 (Danger present) — risk of injury is immediate; the inspector should make the installation safe before leaving site.
- C2 (Potentially dangerous) — urgent remedial action is required, typically within days to a few weeks.
- C3 (Improvement recommended) — not dangerous, but bringing it up to current standards is advised.
- FI (Further investigation required) — a defect's cause or extent is unclear and needs deeper inspection.
Any C1 or C2 code means the overall EICR is marked "unsatisfactory," and the duty holder is expected to arrange remedial work promptly rather than wait for the next scheduled cycle. A C3 alone does not fail the report, but ignoring repeated C3 findings across several inspection cycles tends to attract scrutiny from insurers and from the HSE if an incident later occurs.
How Much Does a Commercial EICR Cost and How Long Does It Take?
Commercial EICR costs vary by the number of circuits, the size of the building and accessibility of the installation, with small single-tenant offices typically costing less than large multi-floor or industrial sites. As a general guide, a small office with a handful of circuits is a modest half-day job, while a multi-floor commercial building or an industrial unit with hundreds of circuits can take several days and involves a correspondingly higher fee.
Exact pricing is not covered by the sourced research for this article and should always be confirmed directly with a qualified inspector, since the figure depends heavily on circuit count, access restrictions and whether testing can be done outside operating hours. What is consistent is the trade-off: a building that schedules its EICR well in advance, with circuits labelled and distribution boards accessible, keeps the inspector's time — and therefore the invoice — down.
Preparing a building before inspection
A few practical steps shorten the inspection and reduce the chance of inconclusive findings:
- Locate and label all distribution boards and consumer units.
- Clear access to electrical cupboards, risers and plant rooms.
- Gather any previous EICR, Electrical Installation Certificate, or minor works certificates.
- Notify tenants or departments of any planned power interruptions.
- List any known faults, recent alterations or DIY electrical work.
- Confirm out-of-hours access if testing needs to happen when the building is unoccupied.
Priority First's facilities management teams coordinate exactly this kind of contractor access across prime central London sites, aligning electrical inspections with out-of-hours building access so tenant operations are not disrupted. This is the same discipline set out in Priority First's own Winter Building Readiness Checklist, which treats electrical and heating system checks as part of a single seasonal compliance sweep rather than isolated events.
"An empty building deteriorates faster than most owners expect — squatting, metal theft, water damage nobody reports because nobody is there. Void property protection is about maintaining a visible pulse: inspections, alarm response and evidence the building is watched. The cost of that pulse is small against reinstating a stripped building." — Mo Hassan, Managing Director, Priority First
That principle applies just as directly to electrical compliance in an occupied commercial building: a missed EICR, like an unwatched vacant property, is a risk that compounds silently until something forces it into view.
Who Should Carry Out a Commercial EICR?
Priority First advises that a qualified electrician holding a recognised competent person scheme registration should carry out any commercial EICR, because BS 7671 compliance and correct code classification require formal electrical qualifications. The main UK schemes are NICEIC, NAPIT and ELECSA, all of which assess and register electricians competent to inspect, test and certify installations against BS 7671.
Priority First advises that a building manager commissioning an EICR should ask for the inspector's registration number and scheme membership before work begins, not after the report arrives. This matters most at claim or dispute stage: an insurer or the HSE will ask who carried out the inspection and under which scheme, and an unregistered inspector's report carries far less evidential weight.
Your commercial EICR compliance checklist
- Confirm your building's premises type (office, industrial, leisure, construction) and its correct maximum interval.
- Check the date and outcome of the last EICR on file before assuming compliance.
- Identify in writing who — landlord or tenant — owns the next EICR under the lease.
- Book a registered NICEIC, NAPIT or ELECSA inspector well ahead of the due date.
- Clear access to distribution boards, risers and plant rooms before the inspection date.
- Treat any C1 or C2 code as an immediate action item, not a future agenda point.
- Log the EICR alongside fire alarm, emergency lighting and fixed wire testing in one compliance calendar.
- Keep the certificate and remedial work records on file for insurers and HSE requests.
FAQ
Priority First on how often an EICR needs to be done in a commercial building
Most commercial premises such as offices and shops need an EICR at least every five years. Industrial premises need one every three years, leisure complexes and pools every year, and construction sites every three months, per IET Guidance Note 3.
Is an EICR a legal requirement for commercial properties in the UK?
The EICR itself is not named in statute, but the Electricity at Work Regulations 1989 legally require electrical installations to be maintained to prevent danger. An EICR is the recognised method of evidencing that duty to the HSE and to insurers.
Who is responsible for arranging an EICR — landlord or tenant?
Responsibility depends on the commercial lease terms, though the underlying legal duty under the Electricity at Work Regulations 1989 sits with whoever controls the installation. Tenants usually own their demised space; landlords usually own shared plant rooms and risers.
What happens if a commercial EICR is overdue?
An overdue EICR risks HSE enforcement, Fee for Intervention charges of £183 per hour during an investigation, and potential invalidation of buildings insurance. The HSE recovered £4.5 million through this scheme in 2026/25 from 5,143 businesses.
What do C1, C2 and C3 codes mean on an EICR?
C1 means danger present requiring immediate action, C2 means potentially dangerous requiring urgent remedial work, and C3 means an improvement is recommended but not mandatory. An FI code means further investigation is needed before the defect can be classified.
Does a change of tenant require a new EICR?
A change of tenant does not automatically trigger a new commercial EICR requirement in the way it does for private rented residential property. Good practice is still to review the existing report's validity and due date as part of any lease change or fit-out.
How is a commercial EICR different from PAT testing?
An EICR inspects the building's fixed electrical installation — wiring, distribution boards and sockets — while PAT testing checks portable appliances like kettles, computers and printers. Most commercial compliance programmes require both, on separate schedules.
Securing compliance across your commercial portfolio with Priority First
Electrical compliance is one strand of a much wider building management picture, and missing an EICR deadline rarely happens in isolation — it tends to sit alongside gaps in fire safety checks, access control and out-of-hours cover. Priority First's facilities management teams manage exactly this kind of compliance calendar for commercial and premium residential buildings across prime central London, coordinating contractor access, tenant notifications and documentation so inspections like the EICR happen on schedule rather than by exception.
Priority First currently manages 24 sites on a single platform, with every checkpoint, contractor visit and compliance task logged and timestamped so building owners have a provable record rather than a filing cabinet of certificates. If your commercial building's electrical compliance, access coordination or wider facilities schedule needs a single accountable partner, get in touch with Priority First for a review of your current arrangements.
