"I just had the electrician in to do the PAT testing, so my building is legally compliant, right?" We hear this question from small business owners and landlords every single week. Unfortunately, mixing up these two electrical safety checks is one of the most common—and dangerous—mistakes you can make.

In the UK, commercial and residential electrical compliance is governed by the Electricity at Work Regulations 1989. To satisfy the law, you must ensure your premises are safe from electrical shocks and fire hazards. However, an EICR and a PAT Test do completely different jobs. Assuming one covers the other is a massive legal trap.

Here is the simple, definitive difference between an EICR and PAT Testing, and exactly why you cannot afford to skip either.

What is an EICR? (The Skeleton)

An Electrical Installation Condition Report (EICR) is the heavy-duty inspection. It focuses entirely on the "fixed wiring" of your building—the hidden electrical skeleton that you cannot easily see or unplug.

During an EICR, a highly qualified electrician will inspect the consumer unit (fuse box), the wiring hidden behind your plasterboard, and all fixed accessories like plug sockets and light switches. They are looking for fundamental, structural dangers such as overloaded circuits, lacking earthing protection, or degrading wire insulation.

  • What it covers: Fuse boxes, mains wiring, sockets, switches, hard-wired lighting.
  • How often it’s needed: Usually every 5 years for commercial properties, HMOs, and residential rentals (sometimes 3 years for industrial/high-risk).
  • Is it a legal requirement? Yes. Operating a commercial space or residential rental without a valid EICR is illegal.

What is PAT Testing? (The Organs)

Portable Appliance Testing (PAT) focuses on the equipment that plugs into the skeleton. If it has a plug and can be moved, it falls under PAT testing.

During a PAT test, a technician will visually inspect the plug and cable of your devices and use a specialised machine to check for earth continuity, lead polarity, and insulation resistance.

  • What it covers: Computers, printers, kettles, microwaves, desk fans, power tools.
  • How often it’s needed: It is risk-based. A construction site power drill might need testing every 3 months; a static office computer might only need testing every 2-4 years.
  • Is it a legal requirement? The law does not explicitly state "You must PAT test." However, the law does state that employers must ensure all electrical equipment is maintained in a safe condition. PAT testing is universally recognised as the only legally defensible way to prove you have done this.
The "Either/Or" Legal Trap Many business owners believe they only need to pay for one or the other. This is how businesses are destroyed.

Imagine you pay £300 for a pristine EICR. Your building's wiring is 100% safe. Three months later, a staff member brings a cheap, faulty phone charger into the office, or the staff kitchen toaster shorts out. It sparks, catches fire, and burns the office down.

When the fire investigator arrives, your EICR is completely useless, because the fire didn't start in the wall—it started in an untested appliance. Because you neglected PAT testing, you failed to maintain safe equipment.

The Devastating Cost of Getting it Wrong

If you fail to commission both an EICR and PAT testing, and an electrical incident occurs (be it an electric shock to a tenant/employee or an electrical fire), the consequences are severe:

The Penalties
  • Void Insurance: Commercial and landlord insurance policies explicitly require you to adhere to all statutory safety regulations. If a fire starts from an untested kettle, the insurer will void the policy, leaving you personally liable for the rebuild costs.
  • HSE Prosecution: Breaching the Electricity at Work Regulations 1989 carries unlimited fines and potential imprisonment if negligence causes injury.
  • £30,000 Council Fines: For residential landlords, failing to provide a valid EICR carries an immediate civil penalty of up to £30,000.

The Smart Solution: Bundle and Save

So, which one do you actually need? You need both.

The EICR proves your building is safe to occupy, and PAT testing proves the appliances your staff or tenants use daily are safe to plug in. To avoid paying two different call-out fees to two different companies, the most cost-effective strategy for small business owners and landlords is to bundle the services.

How to Secure Your Electrical Compliance

1

Audit Your Premises

Check the date on your consumer unit's inspection sticker (EICR) and visually count how many plug-in appliances your business owns (PAT testing). This will allow you to get an accurate quote.

2

Book a Bundled Service

Use our nationwide network to hire an accredited, NICEIC or NAPIT registered electrician to conduct your 5-year EICR and test all portable appliances during the same visit.

3

Maintain the Records

Keep your "Satisfactory" EICR safely on file for the next 5 years, and retain the PAT testing register to prove to your insurers and the HSE that your equipment is actively maintained.
