Portable appliance testing for offices, landlords, licensed premises and trade businesses — every item labelled, a full asset register provided, and sensible retest intervals recommended.
Fixed wire testing covers the installation built into the building. PAT testing covers everything that plugs into it — and in most workplaces, that is where the majority of electrical faults actually occur, because plug-in equipment gets moved, dropped, trailed across floors and generally treated far worse than fixed wiring ever is.
DTF Electrical carry out PAT testing for businesses, landlords and organisations across Liverpool, Kirkby and Merseyside.
Extension leads, multi-way adaptors and trailing sockets are consistently the highest-failure items in any PAT programme — routinely overloaded, damaged and daisy-chained.
Most commercial clients have us carry out PAT alongside fixed wire testing and emergency lighting testing in a single visit, which reduces both cost and disruption.
An electrical maintenance contract puts all three on one managed calendar so nothing gets missed.
Common Questions
There is no single legal interval. Frequency should be based on the equipment and the environment. Annual testing is common for general commercial equipment, with higher-risk items tested more frequently.
The law requires electrical equipment to be maintained in a safe condition; it does not specifically mandate PAT testing. However, PAT testing is the standard, accepted way of demonstrating that duty is being met.
Broadly, anything that connects via a plug and lead — computers, kettles, power tools, extension leads, printers, chargers, floor cleaners, kitchen equipment and IT hardware.
Yes. Every item tested is labelled with the test date and result, and you receive a full asset register listing each item, its location, its result and its next due date.
