Electrical safety isn’t just a legal box to tick; it’s about protecting lives, preventing fires, and ensuring your property runs safely and efficiently. Yet, many London homeowners and business owners are unsure what separates a domestic EICR from a commercial one, and why it matters.

This guide breaks it all down in simple terms: what each report includes, who needs one, how often, and the key differences that affect you.

If you ever need an expert inspection or professional advice, Maintracts’ friendly team is always available on 02086822244.

“An EICR isn’t just paperwork—it’s peace of mind that your electrical system is safe, compliant, and built to last.”

What Is an EICR and Why Is It Important?

An Electrical Installation Condition Report (EICR) is a professional assessment of your electrical system’s safety and condition. It ensures your wiring, sockets, and consumer units are functioning properly and meet UK safety standards.

During an EICR, a qualified electrician checks for:

  • Overloaded circuits
  • Faulty or damaged wiring
  • Signs of ageing or wear
  • Poor workmanship from previous installations
  • Fire or electric shock risks

Each issue is recorded with a code (C1, C2, C3, or FI) to show how urgent it is to repair. Having this report means you’re not just following regulations, but you’re also ensuring your family, tenants, or employees stay safe every day.

Domestic vs Commercial EICR – The Key Differences

Although both reports share the same goal, safety, they differ in scope, complexity, and legal obligations. Let’s look closer.

1. Property Type

Domestic EICR: Covers homes, flats, and rental properties. It’s ideal for homeowners, landlords, or anyone buying or selling a home.

Commercial EICR: Designed for offices, shops, schools, restaurants, or industrial spaces where employees and the public are present.

If you’re running a local café or managing a small office in South London, your setup will likely need a commercial EICR, as it involves more complex wiring and heavier usage.

2. Electrical System Complexity

Domestic systems are relatively straightforward, usually including:

  • Single-phase power
  • Standard lighting and socket circuits
  • A smaller distribution board
  • Commercial setups, on the other hand, often feature:
  • Three-phase power
  • Larger and more complex distribution boards
  • Emergency lighting and high-capacity equipment
  • Data servers or HVAC systems

That means a commercial EICR takes longer, requires advanced testing equipment, and includes more detailed documentation.

3. Legal Responsibilities

Homeowners: No legal obligation, but it’s recommended every 10 years, or before buying or selling a home.
Landlords: Legally required every 5 years under the Electrical Safety Standards in the Private Rented Sector (England) Regulations 2020.

Businesses: Must follow the Electricity at Work Regulations 1989 and the Health and Safety at Work Act 1974. Non-compliance could lead to fines, legal action, or invalidated insurance.
If you manage a business near Clapham or Wandsworth, it’s worth booking a commercial EICR in London sooner rather than later.

4. Frequency of Inspections

The frequency depends on the type of property and how it’s used:
Domestic: Every 10 years for homeowners, or every 5 years for landlords.
Commercial: Typically every 1–5 years, based on building type, occupancy, and insurance terms.
High-risk sites: Gyms, schools, or venues with public access may require more frequent inspections.

5. Duration and Disruption

Domestic EICRs are usually completed in 2–4 hours with little disruption to daily life.

Commercial inspections can take one to three days, often scheduled outside working hours to prevent interruptions.

At Maintracts, we understand downtime can be costly. That’s why our engineers offer flexible appointment times, including evenings and weekends, to fit around your schedule.

6. Report Detail and Documentation

While both reports list any faults or safety concerns, commercial EICRs go further. They may include:

  • Electrical load calculations
  • Circuit diagrams
  • Maintenance schedules
  • Compliance certificates for audits or insurers

Domestic EICRs, meanwhile, provide an accessible overview for homeowners, helping them understand exactly what needs attention.

Why and When Should You Get an EICR?

Whether you own a flat, rent out a property, or run a small business, an EICR helps you:

  • Prevent electrical faults and fires
  • Meet legal obligations and avoid fines
  • Keep insurance valid
  • Provide reassurance to tenants, employees, or customers

You should book an inspection if:

  • It’s been more than five years since the last one
  • You’re moving into a new property
  • Lights flicker or fuses trip frequently
  • You’re renewing your business or landlord insurance

For instance, if your café’s lights keep dimming or your home electrics seem off, it’s time to call for an EICR in London, and a quick check from a professional could save you from major repair costs later.
