EICR vs PAT Testing: What’s the Difference?

Understanding the EICR vs PAT testing difference is important for anyone responsible for a property, workplace, or rental. The two checks are often mentioned together, but they do not cover the same parts of an electrical system.

An EICR looks at the fixed electrical installation in a building, such as wiring, consumer units, sockets and lighting circuits. PAT testing focuses on portable electrical appliances, such as kettles, monitors, printers, extension leads and other plug-in equipment. In many settings, the right answer is not one or the other, but a combination of both depending on the building, the equipment in use, and the level of risk. For the right advice, talk to our team today by calling 020 3633 5087.

The EICR vs PAT testing difference at a glance

The simplest way to understand the  difference is this:

• EICR checks the building’s fixed electrical installation

• PAT testing checks portable electrical appliances

• EICR is typically linked to the condition and safety of circuits and fixed components

• PAT testing is linked to the safety of items that are plugged in and moved, handled or used regularly

• In some properties, only one may be relevant

• In many workplaces and rented settings, both may matter for different reasons

That distinction matters because a property can have a satisfactory fixed installation while still having unsafe appliances. Equally, a set of appliances can be in good condition while the building’s fixed wiring has defects that need attention.

What is an EICR?

An Electrical Installation Condition Report, or EICR, is an inspection of the fixed electrical installation in a property. It is designed to assess the condition of the system and identify deterioration, damage, defects or non-compliance that could affect safety.

An EICR typically covers:

• consumer units

• wiring

• sockets

• lighting circuits

• earthing and bonding

• fixed electrical accessories and parts of the installation

The outcome is a report that records observations and indicates whether the installation is satisfactory or unsatisfactory at the time of inspection.

What is PAT testing?

PAT testing stands for Portable Appliance Testing. It refers to the inspection and, where appropriate, electrical testing of portable electrical equipment to help confirm that it is safe for continued use.

Portable appliances can include:

• computers and monitors

• kettles and microwaves

• extension leads

• chargers

• desk fans

• cleaning equipment

• printers and other office devices

What does an EICR cover that PAT testing does not?

This is where the difference becomes practical.

An EICR is concerned with the electrical infrastructure of the building. It looks at whether the fixed installation is safe and in a suitable condition for continued use. That includes the hidden parts of the system that occupants rely on every day but do not directly handle.

An EICR does not focus on movable plug-in items. So if a kettle has a damaged flex or an extension lead has been misused, that would sit outside the main purpose of the EICR.

Typical issues identified through an EICR can include:

• damaged or deteriorated wiring

• poor earthing or bonding

• overloaded circuits

• unsafe consumer unit issues

• defects in fixed sockets or switches

• departures from current safety standards

That is why an EICR is often viewed as a health check for the building’s underlying electrical installation.

What does PAT testing cover that an EICR does not?

PAT testing focuses on the appliances people plug in and use. These items are often moved, unplugged, stored, shared between users or exposed to wear and tear, which means the risks are different from those found in fixed wiring.

PAT testing can help identify issues such as:

• damaged plugs

• loose or frayed leads

• cracked casings

• incorrect fuses

• signs of overheating

• electrical faults in portable equipment

A property may have a satisfactory EICR and still contain appliances that are unsafe to use. That is one of the main reasons the two checks are not interchangeable.

EICR vs PAT testing difference for landlords

For landlords, the distinction is especially important.

In England, government guidance says private landlords must have the electrical installations in their rented properties inspected and tested by a qualified person at least every five years. That requirement relates to the fixed electrical installation, which is where the EICR comes in.

PAT testing is different. It usually becomes relevant where the landlord provides portable electrical appliances, such as fridges, lamps, kettles or other plug-in items. The same government guidance notes that social landlords who provide electrical equipment must also have that equipment tested, inspected and checked.

So, for landlords:

• EICR relates to the fixed installation

• PAT testing relates to portable appliances supplied with the property

• a furnished or partly furnished property may need both

• an unfurnished property may still require an EICR even if PAT testing is limited or not relevant

EICR vs PAT testing difference for businesses

For businesses, both checks may play a role, but not for the same reason.

An EICR helps assess the condition of the fixed electrical installation in the premises. PAT testing helps manage the safety of appliances employees actually use, such as monitors, kettles, extension leads, printers, chargers and cleaning equipment.

The HSE’s position is important here: portable equipment must be maintained to prevent danger, but not every item in a low-risk workplace needs a formal PAT test. Risk level, frequency of use, user handling, environment and previous history should all help shape the maintenance plan.

In practice, offices, retail units, schools, hospitality settings, workshops and managed properties often need a more joined-up testing strategy because they rely on both a safe fixed installation and safe plug-in equipment.

Which do you need: EICR, PAT testing, or both?

The answer depends on what is being assessed and how the property is used.

You may need an EICR if:

• you are responsible for a building’s fixed electrical installation

• you are a landlord of a rented property in England

• you are buying, selling, managing or refurbishing a property

• you need evidence of the condition of the installation

• the property has not been inspected for several years

You may need PAT testing if:

• you provide portable appliances for staff, tenants or users

• your workplace contains a large number of plug-in devices

• equipment is frequently moved or handled

• the environment creates greater wear and tear

• your safety procedures, insurer or risk assessment call for appliance checks

You may need both if:

• you run a business from commercial premises

• you manage a furnished rental property

• you oversee a site with both fixed systems and supplied appliances

• you want a fuller picture of electrical safety across the property

Common misunderstanding: PAT testing is not a substitute for an EICR

One of the most common mistakes is assuming that PAT testing covers the same ground as an EICR. It does not.

PAT testing will not tell you whether the building’s fixed wiring, earthing, consumer unit, or installed circuits are in satisfactory condition. An EICR will not tell you whether a portable heater, monitor, kettle or extension lead is safe for continued use.

How often should EICRs and PAT testing be done?

There is no single schedule that suits every property.

For private rented properties in England, the fixed electrical installation must be inspected and tested at least every five years by a qualified person. That is the clearest legal benchmark in this area.

PAT testing works differently. The HSE does not set a universal annual PAT requirement for every appliance. Instead, maintenance should be based on risk, with some equipment needing only user checks and visual inspection, and some needing formal combined inspection and testing depending on how and where it is used.

That means a low-risk office laptop charger may not need the same schedule as portable equipment used in a harsher environment.

Why the right testing approach matters

Electrical issues are not always obvious. A fixed installation defect may sit unnoticed until it becomes dangerous. A damaged appliance lead may look minor but still present a risk in daily use.

A sensible testing strategy helps with, protecting occupants and staff, identifying defects early, supporting maintenance planning, improving record keeping and demonstrating a responsible approach to safety.

For businesses and property managers, it also helps create a clearer picture of what has been checked, what needs attention, and where responsibility sits.
