Our Accreditations

What is PAT Testing?

PAT testing is an examination of electrical appliances and equipment to ensure that they are safe to use. Our testers are trained to the City and Guilds (2377) standard in Portable Appliance Testing and are enhanced DBS checked.

Our testers are trained to the City and Guilds (2377) standard in Portable Appliance Testing and are enhanced DBS checked. This gives our clients peace of mind.

Your Responsibility

The Electricity at Work Act (1989) places legal responsibility on employers, employees and self-employed persons to comply with the provisions of the regulations and take reasonably practicable steps to ensure that no danger results from the use of such equipment.
Therefore portable appliance testing is an important part of any Health & Safety Policy.

Totally Subject To Your Risk Assessment

Although it is required that testing be carried out “regularly,” there are no established criteria or guidelines defining what constitutes “regular” or defining how frequently PAT testing should be undertaken.

This is because diverse surroundings and different kinds of equipment each call for a distinct strategy, which is why this is the case.

PAT testing should, at the absolute least, be carried out on a cycle of every two years, as recommended by the general rule of thumb. However, this is only a general suggestion, and there are a few things that need to be taken into consideration in order to decide the testing frequency that is appropriate for your situation.

The following is a description of the many kinds of locations that require PAT testing, along with an explanation of when they will require it.

Commercial Environments

Offices, shops, hotels etc.

  • Testing of Class 1 equipment, often known as ordinary IT equipment, is recommended once every four years.
  • Every two years, portable devices like extension cords should be inspected.
  • Due to the greater risk of damage, equipment that is portable or often used and moved should be inspected once a year.


  • Every year, all class 1 and IT equipment should be checked.
  • Every two years, class 2 equipment needs to be tested.


  • A building site should test any standard 110V equipment as frequently as every three months!


  • Equipment for industrial settings, particularly commercial kitchens, should undergo testing as frequently as every six months.
  • It is advised to evaluate other fixed, mobile, or IT devices every 12 months.

The electrical output of a device and whether or not the user has been adequately shielded from shocks by an earthing wire or insulation are the two primary factors in determining the class ranking system used to classify electrical appliances.

There are two types of appliances that should never be used, and those fall into the first two categories.

Class ‘0’

Class 0 items only have one layer of insulation, which indicates that a single malfunction has a high probability of resulting in an electric shock to the user or, at the absolute least, a spark that may quickly spread into a fire. Since 1975, the United Kingdom has prohibited the sale of such items, which were originally developed for use in extremely dry climates. Christmas tree lights were commonly a Class 0 product prior to the prohibition on such items.

Class ‘01’

The only difference from 0 is that its power cable lacks an earthing connection. There is no earthing contact within the plug. Class 01 items are often high-tech, specialised tools that not everyone needs.

Class 1

All of the plugs and sockets for the items in this category include an earth wire and a built-in earth circuit. If the primary insulation fails, metal components of the items may generate a dangerous voltage. Basically, this implies that the protective conductor must be connected to any metal components of the items. Overcurrent protection, in the form of a fuse or circuit breaker, should be activated in the event of an appliance malfunction. All electrical items, including those used in the kitchen, must undergo PAT testing.

These include – Kettles, Irons, Washing Machines, Toasters, Microwaves, Electric Heaters, Fridges, Freezers and Tumble Dryers.

Class 2

There will be no ground wire in the plug and no earth circuit in these items. Double insulated describes a product that meets the standards to be classified as Class 2. The goal here is to further protect against electrical shock. Good examples of items that should undergo PAT testing are:

Hair straighteners, electric hedge trimmers, video recorders, flat-screen televisions, and table lamps.

Class 3 

Class 3 devices are those that run on SELV (Separated Extra Low Voltage). What this implies is that the gadget can’t generate enough voltage to cause a shock if used improperly. These products typically have a voltage output of either 50vac or 120vdc. Class 3 items do not need to be PAT tested, but their charging leads, for instance, may be a class 2 product and so require testing. Except when used in a medical setting, the following equipment belong in Class 3, meaning they lack adequate protection.

These include:- Smartphones, notebook computers, and energy-efficient light bulbs.


Totally Subject To Your Risk Assessment

Regular user visual inspections and formally conducted visual inspections by a “competent” person work well together to reduce the risks and failure of electrical appliances.

As a result, in addition to equipment testing, safety programmes should also involve visual inspections. Both the frequency of visual inspections and the frequency of electrical testing should be checked on a regular basis.

Every employee on staff is capable of conducting user inspections. These ought to be non-technical, visually guided, and unobtrusive. Operators wouldn’t be asked to utilise testing equipment or open the casings.

These inspections wouldn’t need to be recorded, but in the event that a problem is found, there should be a clear procedure in place for workers to inform the appropriate person in the organisation of the issue that needs to be fixed.

Operatives might benefit from training if they want to know what to look for when using equipment in general and how to report defects.

The categories that each electrical item belongs to are listed below. These will make it a bit simpler to comprehend how frequently PAT testing is required.

Class 1
Basic insulation and reliant on an earth for protection

  • Kettles
  • Microwaves – a microwave emission test should also always be carried out, this is a totally separate test.
  • Fridges/freezers

Class 2
Supplementary insulation and does not rely on an earth for protection

  • TV/DVD players
  • Lamps
  • Power tools

IT Equipment

Supplementary insulations and does not rely on an earth for protection

  • Computers
  • Printers
  • Photocopiers


Moveable equipment

Equipment weighing less than 18k, usually fitted with wheels or casters

  • Oil filled heater
  • Power washer

Hand held equipment

Equipment weighing less than 18k and designed to be operated in the hand

  • Hairdryer
  • PDAs
  • Power drill and tools

Stationary equipment

Equipment weight over 18k without a provided means of carrying

  • Washing machine
  • Chest freezer

110v equipment

Basic insulation and reliant on an earth for protection

  • Certain cement mixers
  • Power adapters
  • Crane lifts

The level of inspection and testing required is dependent upon the risk of the appliance becoming faulty, the type of appliance, the nature of its use and the environment in which it is used. The Institution of Engineering and Technology (IET) Code of Practice for In-Service Inspection and Testing of Electrical Equipment provides the basis for our recommendation.

All customers now have a duty of care under the regulations to provide us with a full risk assessment of your equipment prior to us attending site, this is the bases that we use to form, the testing criteria. If you are unable to do this we can assist you.

As part of our quality assurance, we invite our clients to complete a customer comment form and we are so confident of our service that we would be glad to share this feedback with you.
