What Our Client Say About Us
What Is PAT Testing?
PAT testing (Portable Appliance Testing) is the inspection and testing of electrical appliances to confirm they are safe to use in other words, the process by which an appliance is “PAT tested.” It combines a visual check of the plug, cable and casing with a series of electrical tests earth continuity, insulation resistance and polarity carried out using calibrated PAT testing equipment. Appliances are then labelled pass or fail, and a certificate is issued confirming the results.
PAT Meaning and What “PAT” Stands For
PAT stands for Portable Appliance Testing. The PAT testing definition, in simple terms, is a safety check on any electrical item with a plug from a kettle to a laptop charger to confirm it’s safe to keep using. “PAT tested” simply means an appliance has been through this inspection and passed.
Why It is Now Also Called “EET Testing” (IET 5th Edition)
Under the IET Code of Practice, 5th Edition, the industry term has officially shifted from “Portable Appliance Testing (PAT)” to “In-Service Inspection and Testing of Electrical Equipment,” often shortened to EET Testing. The change reflects that not all tested items are strictly portable; some are stationary or fixed. In practice, “PAT Testing” remains the term almost everyone searches for and uses day-to-day, so we use both interchangeably. What matters is that the underlying inspection standard is the same one your certificate will be tested against.

Electrical Testing
Using calibrated PAT testing equipment, we check for earth continuity, insulation resistance, and polarity to ensure each appliance meets safety standards.
Labelling and Asset Identification
Each tested appliance receives a clear PASS or FAIL label, along with the test date, engineer ID, and a unique barcode to track and log each item accurately.

We log your next test due date in our system and send you automated reminders so you stay compliant without worrying about missed deadlines.
PAT Testing Class | Description | Examples | PAT Test Performed |
Class 1 – Earthed Appliances | Appliances that rely on an earth connection to protect users from electric shock. | Kettles, toasters, washing machines, desktop computers, refrigerators | Visual inspection, earth continuity test, insulation resistance test (or substitute test), and functional check. |
Class 2 – Double-Insulated Appliances | Appliances with double or reinforced insulation that do not require an earth connection. | Hairdryers, power drills, most modern TVs, table lamps | Visual inspection, insulation resistance test (or substitute test), and functional check. No earth continuity test is required. |
Class 3 – Low-Voltage Appliances | Appliances designed to operate at a safe extra-low voltage (SELV), typically below 50V AC or 120V DC, presenting a very low risk of electric shock. | Laptops, mobile phone chargers, low-voltage LED lighting, battery-powered devices | Visual inspection and functional check. Full PAT testing is generally not required due to the low operating voltage. |
How Often Should PAT Testing Be Done? (PAT Testing Frequency)
There’s no single legal interval — the right frequency depends on the type of equipment, how often it’s used, and the environment it’s in. The table below follows IET Code of Practice guidance.
Environment | Class 1 (stationary/IT) | Portable/handheld |
Offices & Shops | Every 48 months | Every 12–24 months |
Construction Sites (110V) | Every 3 months | Every 3 months |
Industrial Environments | Every 12 months | Every 6 months |
Schools | Every 12 months | Every 12 months |
Public-Use Premises | Every 6–12 months | Every 6 months |
These are guideline intervals, not fixed legal deadlines. A proper risk assessment should confirm the right schedule for your specific site.

Is PAT Testing a Legal Requirement in London? (PAT Testing Regulations UK)
Strictly speaking, no single law says “you must PAT test every appliance every year.” What PAT testing regulations in the UK do say is that employers and landlords must keep electrical equipment in a safe condition and PAT testing is the standard, recognised way of meeting that requirement. The key PAT testing requirements come from:
- The Health and Safety at Work Act 1974 — places a general duty of care on employers and landlords
- The Electricity at Work Regulations 1989 — requires electrical equipment to be maintained to prevent danger
- The Provision and Use of Work Equipment Regulations 1998 (PUWER) — requires work equipment to be maintained in efficient working order
If an accident happens and you can’t show any record of testing or maintenance, you may struggle to defend a claim and some insurers will reject a claim outright if equipment hasn’t been properly maintained. For more detail on certification and legal obligations, see our full electrical safety certificate FAQ.
PAT Testing vs EICR — What is the Difference?
These two certificates are often confused, but they cover different things.
PAT Testing | ||
What it covers | Portable/plug-in appliances (kettles, laptops, extension leads) | Fixed wiring, sockets, consumer unit, distribution boards |
Typical frequency | 1–4 years, depending on risk | Every 5 years (rental), or on change of tenancy |
Who needs it | Anyone supplying plug-in equipment | Landlords, and businesses with fixed electrical installations |
Certificate name | PAT Test Certificate | Electrical Installation Condition Report |
Many landlords and businesses book both together in a single visit, since one engineer can usually complete both while on site asking us about combined pricing on our residential EICR or commercial EICR pages. If your EICR comes back with issues, we also carry out EICR remedial work to fix them.
Who Needs PAT Testing?
Landlords & HMOs: If you supply any electrical appliances with rental property kettles, microwaves, lamps you have a duty of care to ensure they’re safe. This is especially important in HMOs, where shared kitchen and communal appliances see heavier use. See our dedicated landlord electrical safety certificate page for the full compliance picture beyond PAT testing alone.
Offices: Desktop computers, monitors, printers, kettles and chargers are the most commonly tested items in office environments. Regular testing also supports your wider health and safety policy and insurance compliance.
Schools & Colleges: Educational sites often have a mix of classroom IT equipment, science lab devices, and canteen appliances all used by large numbers of people daily. We offer term-time-friendly scheduling, including evenings, weekends and school holidays.
Construction Sites: 110V and 3-phase site tools need testing every 3 months under IET guidance, given how frequently they’re moved, dropped and exposed to the elements.
Hospitality And Retail: Kitchen equipment, POS systems, and customer-facing appliances in restaurants, cafes and shops all fall under PAT testing scope particularly relevant given how often these items are handled by staff and the public.

Real Results — Case Studies
Case Study 1 — HMO Letting Agency, East London: A letting agency managing a portfolio of HMO properties across East London needed PAT testing completed ahead of a licensing renewal deadline. We tested appliances across the full portfolio within a single week, flagging a small number of failed items — mostly damaged extension leads which were repaired free of charge on-site. A full digital asset register was delivered within 24 hours, in time for the renewal.
Case Study 2 — Independent Restaurant Group, Central London: A multi-site restaurant group needed all kitchen and front-of-house equipment tested without closing during service. We scheduled testing before opening hours across a single week, completing every site with zero disruption to trading.
Case Study 3 — Primary School, North London: Working around term-time constraints, we completed a full-site test covering classroom IT, science lab equipment and canteen appliances during a single weekend, delivering documentation in time for the school’s safety review.
PAT Testing vs EICR – Understanding the Difference
These services address different aspects of electrical safety.
Portable appliances versus fixed wiring:Portable Appliance Testing focuses on plug-in equipment. EICR assesses fixed installation wiring.
Scope of inspection and level of testing:PAT is appliance-specific. EICR involves inspection of circuits, consumer units and distribution systems.
When both services may be required:Landlords and commercial property owners often require both to demonstrate comprehensive electrical compliance.
Coordinating electrical compliance services efficiently:We can advise on aligning inspection schedules to reduce disruption.
