If you manage a workplace, rent out property, or oversee electrical equipment in any capacity, you have likely encountered the question of PAT testing at some point. The confusion around what is and isn’t required can lead businesses and landlords to spend more money than necessary, or alternatively, to overlook genuine safety obligations. Understanding exactly what items don’t need PAT testing is just as important as knowing what does.
PAT testing, or Portable Appliance Testing, refers to the process of inspecting electrical equipment to ensure it is safe to use. Despite the widespread assumption that everything with a plug requires formal testing, this is far from the case.
What Does Not Require PAT Testing?
Not every piece of electrical equipment in your building needs to go through a formal PAT test. In fact, a significant number of items are either excluded entirely or only require a basic visual inspection rather than a full electrical test.
Fixed electrical appliances, such as built-in ovens, hardwired lighting, and permanently installed heating systems, fall outside the scope of PAT testing entirely. Similarly, items that are battery-operated or powered by a low-voltage adaptor, such as small desk fans running on AA batteries, do not require PAT testing since they pose no mains electrical risk.

Items That Require a PAT Test: Understanding the Boundaries
It helps to understand which items do require testing in order to appreciate where the boundaries lie. Class I equipment, which relies on an earth connection for safety, and Class II double-insulated equipment both fall within the remit of PAT testing, though the frequency and method of testing differs between them.
Extension leads, power tools, kettles, computers, and floor-standing lamps are all classic examples of items that should be formally tested. The key factor is whether the item is portable, connected to mains electricity, and capable of presenting a risk if it develops a fault.
| Equipment Type | PAT Testing Required? |
|---|---|
| Portable mains-powered tools | Yes |
| Battery-only operated devices | No |
| Fixed hardwired appliances | No |
| Extension leads | Yes |
| Double-insulated chargers (Class II) | Low risk, visual check advised |
| Stationary IT equipment (low risk) | Periodic visual inspection |
| Kettle or toaster | Yes |
| Solar-powered garden lights | No |
Is PAT Testing a Legal Requirement in the UK?
This is one of the most commonly misunderstood aspects of electrical safety in the workplace. PAT testing itself is not explicitly required by any specific UK law, but the legal duty to maintain safe electrical equipment absolutely is.
The Health and Safety at Work etc. Act 1974 and the Electricity at Work Regulations 1989 both place a duty of care on employers to ensure electrical equipment is safe. PAT testing is simply one recognised method of demonstrating compliance with those obligations, and for many businesses it remains the most practical approach.
Does an iPad Need PAT Testing?
The question of whether an iPad needs PAT testing catches many people off guard. Tablets like iPads are typically charged using a Class II double-insulated adaptor, which is considered low risk, and the device itself runs on an internal battery rather than direct mains power.
In most workplace settings, iPads and similar tablets do not need formal PAT testing. However, the charging cables and adaptors used with them may still benefit from a visual inspection to check for damage, particularly in high-use environments such as schools or healthcare settings where equipment changes hands frequently.
| Device | Mains Connected? | PAT Test Required? |
|---|---|---|
| iPad (battery powered) | No | No |
| iPad charging adaptor (Class II) | Yes (indirectly) | Visual check advised |
| Laptop with external power supply | Yes (via adaptor) | Low risk, visual inspection |
| Desktop computer | Yes | Yes |
| Smartphone charger | Yes (indirectly) | Visual check recommended |
| Portable power bank | No | No |
Reducing Unnecessary Testing Costs Without Compromising Safety
One of the most practical steps any business can take is to introduce a formal risk assessment process before scheduling PAT testing. This allows you to categorise equipment by class, usage frequency, and environment so that resources are directed where they are genuinely needed rather than applied uniformly across all assets.
The Health and Safety Executive (HSE) provides clear guidance on how to approach this, noting that a risk-based approach is far more effective than blanket annual testing. Low-risk office environments with double-insulated equipment may only require testing every four to five years, while construction sites or equipment used in harsh conditions should be tested far more frequently. reference point for any business reviewing its compliance position.n the workplace, the Health and Safety Executive provides detailed FAQs on PAT testing obligations, frequency, and what constitutes competence.

Completing the Picture on What Items Don’t Need PAT Testing
Understanding what items don’t need PAT testing is not about cutting corners on safety. It is about applying a proportionate, evidence-based approach that focuses time and money where genuine electrical risk exists, while avoiding unnecessary testing of equipment that presents little or no hazard.
The most important takeaway is that the law requires you to maintain safe electrical equipment, not to PAT test everything you own. Recognising the difference between fixed appliances, battery-powered devices, and low-voltage Class II equipment allows you to build a sensible testing schedule that satisfies your legal obligations without excessive cost.
For businesses reviewing their current approach, it is worth combining a formal risk assessment with a visual inspection programme. Many items that were previously sent for annual PAT testing may turn out to need only an occasional check, and identifying this can free up meaningful budget while keeping your workplace fully compliant.
What Items Don’t Need PAT Testing: Frequently Asked Questions
No, battery-operated devices do not require PAT testing because they are not connected to the mains electricity supply. They present no risk of electrical shock via the mains and therefore fall outside the scope of the testing process.
A laptop itself runs on an internal battery, but the external power supply or charger connected to the mains may require inspection. In low-risk office environments, a periodic visual check is typically sufficient rather than a full formal test.
There is no specific law requiring landlords to PAT test appliances, but they are legally obligated to ensure all electrical items provided to tenants are safe. Many landlords choose PAT testing as a straightforward way to demonstrate compliance and protect themselves from liability.
Class I appliances rely on an earth connection as part of their safety mechanism, whereas Class II appliances are double-insulated and do not require an earth. Class II items are generally considered lower risk, and their testing requirements are less stringent than Class I equipment.
iPads themselves do not require PAT testing since they operate on internal batteries, though the charging adaptors used in school environments should receive regular visual inspections. Given the high volume of use in schools, it is good practice to include charging equipment in a routine inspection programme.
Testing frequency depends on the type of equipment, the environment in which it is used, and the risk level assessed by the responsible person. Construction equipment may need testing every three months, whereas low-risk office equipment may only require testing every four to five years.
Fixed appliances that are hardwired into the electrical installation, such as built-in cookers or electric panel heaters, do not fall within the scope of PAT testing. These are instead covered by periodic fixed wiring inspections carried out by a qualified electrician.
PAT testing is the routine inspection and electrical testing of portable appliances to verify they are safe to use, and you can read more about its background on the PAT testing Wikipedia page. It matters because faulty electrical equipment is a leading cause of workplace fires and electric shock incidents in the UK.
PAT testing can be carried out by a competent person rather than a certified electrician, provided they have sufficient knowledge and the right equipment. Many businesses train a member of staff to conduct basic visual inspections and use a PAT testing device for formal electrical checks.
Phone chargers are Class II double-insulated items and are considered low risk, so formal PAT testing is rarely required. A regular visual check for signs of damage, fraying, or overheating is generally considered sufficient in most workplace environments.
Yes, extension leads are among the most important items to include in a PAT testing programme because they are frequently moved, plugged and unplugged, and subject to physical wear. Damaged extension leads are a common cause of electrical fires, making them a priority for inspection.
A comprehensive PAT test covers both the appliance and its plug, including a check on the internal wiring of the plug itself. This is particularly important for older equipment where plugs may have been replaced or rewired at some point.
While there is no legal requirement to maintain PAT testing records, the Health and Safety Executive recommends keeping a log as evidence of due diligence. Records should include the item description, test date, result, and the name of the person who carried out the test.
Equipment that fails a PAT test should be taken out of service immediately and labelled clearly to prevent accidental use. It should either be repaired by a qualified person and retested before being returned to service, or disposed of safely if it cannot be economically repaired.
