PAT Testing for London Businesses: What Should Be Tested and When?
If you are searching for PAT testing London services, you are probably trying to answer two practical questions before you book: which appliances need testing, and how often should it be done? For many London businesses, that is where uncertainty starts. Offices, shops, studios and shared commercial spaces can contain a surprisingly long list of plug-in equipment, but not every item carries the same level of risk.
At Electroways Ltd, we take a sensible, risk-based approach to appliance safety. The aim is to help businesses keep electrical equipment in good order, reduce avoidable risk and maintain clear testing records. Rather than applying the same schedule to every appliance, it makes more sense to look at what you use, where you use it and how much wear it sees day to day.
What PAT testing actually covers
PAT testing stands for portable appliance testing. In practice, it usually involves a formal visual inspection and, where appropriate, electrical testing of portable and plug-in equipment.
For employers, landlords and anyone responsible for commercial premises, the key point is simple: electrical equipment supplied for use at work should be kept safe. PAT testing is one of the most practical ways to support that duty, especially when multiple staff members use the same appliances or when equipment is moved around regularly.
It is also worth remembering that PAT testing is not limited to large or obviously heavy-duty appliances. Some of the most commonly overlooked risks come from small chargers, trailing leads and adaptors that are used every day without much thought.
PAT testing London: which appliances should be tested?
As a rule, most business-owned plug-in appliances should be reviewed for inclusion in your testing schedule. The exact list will depend on your premises, but the following categories are the most common.
Office and IT equipment
In many workplaces, this is the largest group of appliances. It can include desktop computers, monitors, docking stations, printers, scanners, laptop chargers, phone chargers, desk lamps and fans.
These items are often lower risk than hand-held tools or kitchen appliances, but they should still be part of a proper asset list. Damaged leads, loose plugs and worn connectors are all issues that can be missed if nothing is being checked.
Kitchen and staff welfare appliances
Staff kitchens and breakout areas usually contain some of the most heavily used items in the building. Kettles, microwaves, toasters, coffee machines, fridges and water dispensers are all worth reviewing.
Because these appliances are often switched on and off frequently, exposed to heat or used by multiple people, they can require closer attention than equipment left undisturbed on a desk.
Extension leads, adaptors and chargers
If there is one category that businesses should never ignore, it is this one. Extension leads, multi-socket adaptors, extension reels and charging equipment are moved, bent, unplugged and reused constantly.
They are also among the items most likely to show signs of damage or misuse. In many offices and commercial units, these accessories create more day-to-day risk than the larger appliances connected to them.
Cleaning equipment and portable tools
Vacuum cleaners, floor machines, hand-held tools and maintenance equipment usually deserve a higher priority on a PAT testing programme. That is because they are moved regularly, handled more intensively and more likely to suffer cable strain or impact damage.
For businesses with back-of-house areas, workshops, storage rooms or frequent fit-out work, this category should be reviewed carefully.
Customer-facing and temporary equipment
Portable heaters, display lights, card machine power supplies, seasonal items and equipment used for pop-up spaces or events can easily be forgotten. These appliances often come in and out of use quickly, which means they can fall outside normal maintenance routines unless someone is keeping clear records.
Appliances that may need a different type of inspection
PAT testing does not replace inspection of your fixed electrical installation. Hard-wired systems, sockets, circuits and other fixed elements of the property normally fall under wider inspection work instead. If your premises need broader checks, our electrical inspecting and testing service can support a more complete approach.
When should business appliances be tested?
There is no single timetable that suits every business and every appliance. A monitor in a dry, low-traffic office is not exposed to the same risks as a kettle in a communal kitchen or a vacuum cleaner used across several rooms every day.
A sensible schedule is usually based on the following factors:
Type of appliance: Hand-held and heat-generating items generally need closer attention than equipment that stays in one place.
Working environment: Dry offices are lower risk than kitchens, workshops, storerooms or shared amenity areas.
Frequency of use: Equipment used constantly will usually need reviewing more often than items used occasionally.
Movement and handling: The more an appliance is moved, plugged in, unplugged or transported, the greater the chance of wear.
Previous damage or repairs: If an item has failed before or has recently been repaired, it should be looked at more closely.
In practice, many businesses combine day-to-day user awareness with formal visual inspections and periodic electrical testing. Damaged items should be taken out of use straight away and reviewed before being put back into service.
Lower-risk office equipment
Desktop computers, fixed monitors and similar items in stable office environments often follow a different testing rhythm from appliances that are moved frequently. They still need to be recorded and checked, but the risk profile is usually lower.
Higher-risk appliances
Kitchen equipment, cleaning machines, portable tools, extension leads and appliances used in shared spaces generally justify more frequent attention. The more handling, heat, moisture or strain an item sees, the more important regular inspection becomes.
After changes to your premises
It is wise to review your PAT testing schedule after an office move, refit, change of layout, rapid team growth or a wave of newly purchased equipment. These are the moments when asset lists and labels often stop matching reality.
Common signs your business may be overdue PAT testing
Not sure whether your current testing schedule is still fit for purpose? These are common warning signs:
You do not have a current list of business-owned plug-in appliances.
Extension leads and adaptors are used everywhere, but nobody knows when they were last checked.
Staff share kettles, microwaves, chargers or portable heaters that have visible wear.
You have recently moved office, refurbished space or added new workstations.
Equipment labels are missing, out of date or inconsistent.
You cannot easily identify which appliances belong to the business and which have been brought in informally.
If any of these sound familiar, it is usually a good time to review your arrangements and put a clearer system in place.
PAT testing and EICR: why many London businesses need both
One of the biggest areas of confusion is the difference between PAT testing and an EICR. They are related, but they do different jobs.
PAT testing focuses on portable or plug-in appliances. EICR testing focuses on the fixed electrical installation of the property, including circuits, sockets and associated systems. One does not replace the other.
For many businesses, the most practical approach is to treat appliance testing as part of a wider electrical safety plan. Electroways Ltd also provides PAT testing in London, wider inspection work and support as commercial electricians in London, which is useful if you want one point of contact for routine testing and broader electrical concerns.

What a PAT testing visit usually includes
While every site is different, a typical visit usually follows a straightforward process:
Reviewing the equipment: identifying which appliances should be included.
Formal visual checks: looking at plugs, cables, casings and obvious signs of damage or misuse.
Electrical testing where appropriate: carrying out suitable tests for the relevant appliance type.
Recording the outcome: identifying items that pass, fail or need to be removed from use.
Planning next steps: helping you decide what should be monitored, replaced or reviewed again in future.
This kind of structured process makes it easier to keep on top of your equipment and avoid unnecessary disruption later.
FAQs about PAT testing London
Is PAT testing a legal requirement for London businesses?
Businesses have a duty to keep electrical equipment safe. PAT testing is a common way to support that duty and document a sensible maintenance process, but there is not a blanket rule that every appliance must be tested on the same annual timetable.
How often should office appliances be PAT tested?
That depends on the appliance type, the environment and how much handling it gets. A fixed office monitor is usually lower risk than a kitchen appliance, extension lead or portable cleaning machine, so testing intervals should reflect actual use.
Do extension leads, adaptors and chargers need PAT testing?
In many cases, yes. These are some of the most frequently moved and most easily damaged items in a workplace, so they should not be left off your asset list.
What is the difference between PAT testing and an EICR?
PAT testing covers portable appliances and plug-in equipment. An EICR covers the fixed electrical installation within the premises. Many businesses benefit from both, especially where there are multiple appliances and older electrical systems.
Can Electroways Ltd help with other electrical services?
Yes. In addition to PAT testing, we provide electrical inspecting and testing, landlord safety certificates, commercial electricians, domestic electricians and electrical installations from our London base.
