If you run an office in Fountainbridge, a shop on Morningside Road or a workshop near Slateford, the electrical installation behind your walls is working every hour you are open. It is also your legal responsibility. A commercial EICR (Electrical Installation Condition Report) is the standard way to show that the installation is safe, and one of the first documents an insurer, landlord or fire officer is likely to ask for.
The difficulty is that there is no single date stamped on the law. How often your premises need a commercial EICR depends on the type of building, how it is used and the condition of the installation. This guide explains where the duty comes from, the recommended testing intervals for common types of commercial property in Edinburgh, and what happens during and after an inspection.
Why Commercial EICRs Matter for Edinburgh Businesses
The legal starting point is the Electricity at Work Regulations 1989, which apply across Great Britain, including Scotland. Regulation 4 requires electrical systems to be maintained so as to prevent danger, so far as is reasonably practicable. The regulations do not say “test every five years”, but in practice periodic inspection and testing is how most businesses show they are meeting that duty.
Insurers take the same view. Many commercial policies include conditions about electrical maintenance, and a missing or out-of-date report can complicate a claim after a fire or an electrical fault. Commercial landlords often write testing obligations into leases as well, so tenants in shared office buildings in the West End or Fountainbridge may be responsible for their own areas even when the landlord covers the landlord’s supply.
There is also a simple practical reason. An EICR finds faults before they become failures: loose connections that run hot, overloaded circuits in a kitchen that has grown over the years, or missing protection on sockets that now power far more equipment than they were designed for. The HSE’s guidance on electrical maintenance is a useful reference for employers, and any faults found can be put right through our electrical repairs service.
Recommended EICR Intervals by Type of Premises
Electricians in the UK work to BS 7671, and the IET’s Guidance Note 3 sets out recommended maximum intervals between periodic inspections. These are starting points rather than fixed rules, and the inspector can recommend a shorter interval if the installation is in poor condition or heavily used. If you look after several buildings, our services for property managers can bring their testing dates into one schedule.
Offices, shops and restaurants
For offices, shops, restaurants and hotels, the usual recommended maximum interval is five years. That covers a large share of the commercial properties along the Bruntsfield Place and Morningside Road high streets and the newer office space around Fountainbridge.
Five years is a ceiling, not a target. A café with commercial cooking equipment, extraction and dishwashers working all day puts far more strain on its installation than a quiet office, so its EICR may come back with a shorter recommended retest date.
Industrial units and workshops
Industrial premises usually have a recommended interval of three years. Workshops, light industrial units and storage buildings tend to have more motor loads, more wear on flexible cables and harsher conditions, such as dust, vibration and moisture, so faults develop faster.
Businesses with units in the industrial estates around Slateford or Craigmillar should plan on a three-year cycle as a minimum, with interim checks of high-risk areas between full inspections.
Higher-risk and public venues
Places of entertainment and some leisure premises carry shorter recommended intervals, often three years or less. Swimming pools and similar special locations are typically inspected every year. If your premises hosts the public in large numbers, such as a theatre, nightclub or event space near the Castle and the Grassmarket, check the recommended interval with your electrician rather than assuming five years.
What Happens During a Commercial EICR
A commercial EICR is a combination of visual inspection and electrical testing. The electrician checks the condition of the distribution boards, cables, accessories and earthing, then tests a sample of circuits, or all of them where the size and condition of the installation calls for it.
Planning matters because testing usually means isolating circuits for short periods. A good contractor will agree a schedule with you in advance, so tills, servers, fridges and lifts are not switched off at the wrong moment. Many businesses book testing early in the morning, in the evening or over a quieter day of the week to keep disruption low.
You will receive a written report that records the condition of the installation and lists any observations. These are given codes:
- C1 means danger is present and immediate action is needed
- C2 means the issue is potentially dangerous and needs urgent remedial work
- C3 means improvement is recommended but the issue is not dangerous in itself
- FI means further investigation is needed before the risk can be judged
A report with any C1, C2 or FI observations is classed as unsatisfactory. That is not unusual for older buildings, and it is not a reason to panic. It gives you a clear list of what needs to be fixed and in what order. You can see examples of the commercial work we carry out in our case studies.
What to Do After Your Commercial EICR
Once remedial work is completed, ask for the relevant certificates so that your records show both the problem and the fix. Keep the EICR, the remedial certificates and any related invoices together, because insurers and auditors will want to see the full picture.
Set a reminder for the next inspection date given in the report. Larger organisations often move to a rolling programme, testing part of the installation each year so the full building is covered within the recommended interval. That approach spreads cost and reduces disruption, and it suits multi-floor offices and retail units with long trading hours.
The EICR covers the fixed installation only. Portable appliances, emergency lighting and fire alarm systems all have their own testing routines. Our compliance testing service covers EICRs, emergency lighting tests and PAT testing, so all three can be planned together. For ongoing work, a planned electrical maintenance schedule can keep everything on track between inspections.
Conclusion
The right EICR interval depends on what your building is and how hard it works. Five years is typical for offices, shops and restaurants, three years for industrial premises, and less for high-risk venues, but the condition of your installation always has the final say. Treat the report as a maintenance plan rather than a pass or fail test, and it becomes one of the most useful documents your business holds.

Frequently Asked Questions
Is a commercial EICR a legal requirement in Scotland?
There is no single law that names a fixed EICR date for most commercial premises. However, the Electricity at Work Regulations 1989 require installations to be maintained to prevent danger, and periodic inspection is the accepted way to show you are meeting that duty. Insurers and leases often make it a formal requirement too.
How long does a commercial EICR take?
It depends on the size and complexity of the installation. A small shop or office may take a few hours, while a large multi-floor building can take several days. Your electrician should give you an estimate after looking at the number of distribution boards and circuits involved.
Who is responsible for the EICR in a rented commercial unit?
Responsibility is usually set out in the lease. Often the landlord covers the landlord’s supply and common areas, while the tenant is responsible for the installation within their own unit. If the lease is unclear, ask your landlord or managing agent before booking, so that nothing is tested twice or missed entirely.
What happens if my commercial EICR is unsatisfactory?
The report will list the issues that need attention, ranked by urgency. Any C1 issues need immediate action, and C2 and FI observations should be dealt with promptly. Once the work is complete, your electrician will issue certificates confirming the remedial work, which you should keep with the original report.
