Baffled by portable appliance testing? No idea whatsoever where to begin? Never fear - the PAT experts are here to help.
Don't think you're alone in wondering what PAT tester is right for you. With loads of models on the market, all with different capabilities, it can be very confusing as you try to work out exactly which one is right for your application.
This blog is designed to hopefully help you understand the difference between several types of PAT tester and to hopefully help you figure out which type you need.
Whoa there - don't just jump in at the deep end!
Although it is true that anyone can perform PAT testing, you must be deemed 'competent' to do so. Although there is no legal requirement for someone to attend PAT training, it is strongly recommend that you do so in order to make sure you understand how the testers work, and how to perform the procedures.
There is no complete definition of what makes someone competent, although an understanding of how appliances work, and electricity, is pretty essential. The Electricity at Work Regulations of 1989 state that where required, inspecting and testing must be carried out by a competent person, but there is no benchmark for what this means. It has become common in recent years for most people who want to PAT test to gain this competency through training, although for those with an electrical background already, this may not be necessary.
Before you even consider buying a PAT tester, also consider your training. There are many different options available out there for training you up to be a PAT tester (we ourselves run regular training courses throughout the year, and also have a training DVD where you can learn from home or at work).

Once you're trained, you need to figure out exactly what type of appliances you'll be testing, and how often you'll need to do it.
For example, if you were a small charity or office with only a few appliances, you'd be testing likely once every couple of years. In comparison if you're considering starting your own PAT testing business, you'll probably be testing constantly, checking thousands of appliances every year.
For those with a small amount of appliances to test, there is little point in shelling out a fortune on a really expensive tester, as it'll be full of features you don't need. In comparison, a professional user is much more suited to what's known as a professional-grade PAT tester, as these include several advanced features designed to make life easier.
You may also be using specific equipment that uses 110V supply. If this is the case, you'll need a tester with 110V capability in order to test these appliances accurately and safely (we'll get into that more further on in the article).
Consider the following:
Now that you've thought about that, it's time to get into the details about what types of PAT tester there are.
Here at Tester.co.uk, we classify our PAT tester into four groups: basic PAT checkers, basic PAT testers, mid-range and professional.
The idea here is simple: if you're testing not very frequently, want something basic and don't test many appliances, opt for a PAT checker or a basic tester. If you're testing a larger amount of appliances regularly, or have specific types of equipment not suitable for normal testing, it is best to opt for a mid-range or professional tester.
Although the capability of each tester varies depending on the particular model, this outlines the basic difference between each type of tester.
As simple as it gets, PAT checkers do the bare minimum you need to ensure an appliance's electrical safety.
Here's a few facts you need to know about PAT checkers:
Recommended for use by: those brand new to PAT testing, or those with an extremely small amount of appliances to test
Current List of PAT Checkers
Still made with beginners in mind, PAT testers with basic classification are designed to do the bare minimum you'll need to verify an appliance's electrical safety. Unlike PAT checkers, basic testers are capable of displaying full test readings alongside a PASS/FAIL indicator (ideal for keeping comprehensive logs of your tests).
As their name suggests, they're made with beginners in mind.
Here's what you need to know about basic PAT checkers:
Recommended for use by: offices, shops, smaller hotels and charities. Ideal as a beginner option, or for those with a small amount of appliances to test.

We're getting into the more complex options now. Mid-range models are ideal for those looking to start a PAT testing business, with upwards of 500 appliances to test per year.
Unlike basic testers, mid-range models come with a selection of extra functions (varies depending on model). Several - but not all - of the mid-range models are downloadable; this means they have integrated memory and you can log and download your testing data to PC (as long as you have the manufacturer's software, which is sometimes sold separately).
Due to the advanced capabilities, the price of mid-range models is significantly higher than basic testers. Prices still vary greatly, from as low as £270 to as high as just under £600. The more expensive models - such as Megger's PAT350 - have more features, including flash testing, configurable testing procedures, colour screen, QWERTY keyboard for amending testing records and more.
Here's what you need to know about mid-range PAT testers:
Recommended for use by: those interested in starting a PAT testing business, or firms with more than 500 appliances to test per year. Also ideal for those who want the ability to log data automatically, rather than manually (not available on all testers).

Top of the range, professional PAT testers are the tools you need if you're serious about PAT testing.
Most commonly used by PAT engineers who actually do it on a daily basis as part of their work, they should be bought and used by people with thousands of appliances to test every year.
Every model in the professional range is a downloadable tester - you can expect to be able to store several thousand records on the tester's memory, and download it to PC. You will however need to consider software purchases, as this is often not included as standard with many of the testers (although there are exceptions).
Here's what you need to know about professional PAT testers:
Recommended for use by: people serious about PAT testing. You should be testing thousands of appliances every year, and do PAT testing extremely regularly. Also ideal as a means of keeping customer and appliance data logged without lots of effort.
