EICR vs PAT Testing: What’s the Difference?

If you have been told you need an EICR, PAT testing, or both, it usually comes up at the least convenient time - when a tenancy is starting, a property is being checked over, or you are trying to sort out safety issues without getting buried in jargon. The question of eicr vs pat testing is a common one, and the answer is fairly simple once you know what each test is actually for.

An EICR checks the fixed electrical installation in a property. PAT testing checks portable electrical appliances. They are not the same job, they do not cover the same risks, and one does not replace the other. If you are a homeowner, landlord, or tenant trying to work out what is needed, the easiest way to think about it is this: the wiring belongs to the property, while appliances are the things plugged into it.

EICR vs PAT testing: the basic difference

An EICR stands for Electrical Installation Condition Report. It looks at the fixed electrics in a property, including things like the consumer unit, sockets, lighting circuits, earthing, bonding, and the general condition of the wiring. The purpose is to assess whether the installation is safe for continued use.

PAT testing stands for Portable Appliance Testing. It applies to electrical appliances that can be moved or unplugged, even if they normally stay in one place. That could include kettles, lamps, microwaves, extension leads, televisions, vacuum cleaners, and landlord-supplied white goods.

So if you are comparing eicr vs pat testing, the real difference is what is being inspected. One is about the property’s electrical system. The other is about plug-in items.

What an EICR actually covers

An EICR is a proper inspection and test of the fixed installation. It is not just a quick look around. The electrician carries out visual checks and electrical tests to identify wear and tear, damage, outdated components, poor previous work, or anything that could lead to electric shock or fire risk.

This can include checking whether circuits are overloaded, whether protective devices are suitable, whether the earthing and bonding are up to standard, and whether the consumer unit offers the level of protection expected today. In older homes, an EICR often picks up things that may have worked for years but no longer meet current safety standards.

For landlords in Scotland, an EICR is part of the electrical safety requirements in rented property. It is not optional if the property is being let. For homeowners, it may not be a legal requirement in the same way, but it is still a sensible safety check, especially if you have moved into an older property, carried out alterations, or are dealing with recurring faults such as tripping circuits or dead sockets.

An EICR does not test every appliance in the home. If the kettle or toaster is faulty, that would not usually be picked up by the EICR unless there was an obvious issue noticed during the visit.

What PAT testing actually covers

PAT testing is aimed at appliances rather than the wiring in the walls. It involves a visual inspection first, because many faults are visible before any tester is used. Cracked plugs, damaged leads, loose connections, scorch marks, and the wrong fuse are all common examples.

Where appropriate, the appliance is then tested with specialist equipment to check things like earth continuity, insulation resistance, and polarity. The exact tests depend on the type of appliance.

For landlords, PAT testing is often relevant where appliances are supplied as part of the tenancy. If you provide a microwave, kettle, fridge freezer, table lamp, or extension lead, those items need to be safe. PAT testing gives you a clear record that they have been checked.

For homeowners, PAT testing is usually less formal and less commonly requested, but it can still be useful in certain situations, especially if you are concerned about older appliances or equipment that gets heavy use.

Do landlords need both?

Quite often, yes.

This is where confusion tends to happen. A landlord gets an EICR done and assumes that covers everything electrical in the property. It does not. The EICR covers the installation. If the property is let furnished or with supplied appliances, those appliances also need to be safe.

In practice, that means the property wiring may need an EICR while the supplied appliances may need PAT testing or at least suitable inspection and testing as part of your duty of care. What is appropriate depends on the type and number of appliances, the condition they are in, and how the property is used.

A partly furnished flat with a few basic appliances is different from a fully furnished rental with multiple supplied electrical items. That is why a one-size-fits-all answer does not really work.

When an EICR is the priority

If you are only going to deal with one issue first, and there are concerns about the fixed electrics, the EICR usually comes first. Faults in the installation can affect the safety of the whole property. A damaged socket circuit, poor earthing, or an outdated consumer unit is not something to leave sitting.

An EICR is also the priority when a tenancy is due, when buying or moving into an older house, after significant electrical alterations, or when there are repeated electrical problems that do not have an obvious cause.

If lights flicker, fuses trip, sockets feel loose, or parts of the property seem dated, the fixed installation needs checked properly. PAT testing would not answer those problems.

When PAT testing is the priority

PAT testing moves up the list when the appliances themselves are the main concern. For landlords, that is usually when supplying electrical items to tenants. For example, if you provide kitchen appliances, floor lamps, or extension leads, those are your responsibility to supply in a safe condition.

It is also useful where appliances have had rough use, have been in storage, are second-hand, or show signs of damage. A frayed flex on a lamp or a cracked plug top on a microwave may sound minor, but these are exactly the sort of faults that can lead to trouble.

PAT testing is not a substitute for common sense, though. If an appliance is visibly unsafe, it should be taken out of use straight away rather than simply labelled and left in service.

EICR vs PAT testing for homeowners

For most homeowners, PAT testing is rarely the first thing they ask for. The bigger concern is usually the condition of the house electrics themselves - especially in older properties where the wiring may not have been inspected for years.

That said, homeowners often mix the two up because both are described as electrical testing. If you are worried about the safety of your sockets, lighting, fuse board, or wiring, ask for an EICR. If you are worried about specific plug-in appliances, that is PAT testing.

If you are not sure which one applies, a good electrician should be able to tell from a quick conversation. You should not need to guess your way through it.

Why people mix them up

The names do not help. EICR sounds technical, PAT sounds official, and both get mentioned around landlords, certificates, and safety checks. On top of that, people often use phrases like electrical certificate or electrical test to describe both, even though they cover different things.

Another reason is that both can be arranged around the same time, especially in rental properties. If a landlord is getting a property ready for new tenants, it makes sense to look at the condition of the fixed electrics and the supplied appliances together. That can make it sound like one combined service, even though it is still two separate areas of inspection.

The practical way to think about it

If it is fixed to the property or part of the installation, think EICR. If it plugs in, think PAT testing.

That simple rule will not cover every edge case, but it works for most homes and rentals. It also helps you avoid paying for the wrong inspection or assuming one test has covered something it has not.

For landlords especially, being clear on this can save hassle before a tenant moves in. For homeowners, it can help you get the right job booked when something does not feel quite right.

At David Ronald Electrical, this is the kind of thing that is easier sorted with a straight answer than a lot of technical talk. If you know what each test is for, you are already in a much better position to keep the property safe, stay compliant where needed, and deal with problems before they turn into bigger ones.

If you are unsure whether your property needs an EICR, PAT testing, or both, the best next step is simply to ask - because the right test depends on what is in the property, who is using it, and whether the issue is with the wiring or the appliances.
