Portable Appliance Testing (PAT): How Often Should London Businesses Test Their Equipment?
Introduction
For businesses across London, ensuring the safety of electrical appliances isn’t just a recommendation — it’s a legal and moral responsibility. Portable Appliance Testing (PAT) plays a crucial role in maintaining workplace safety by identifying potential faults before they lead to electrical shocks, fires, or equipment failure.
London offices, restaurants, shops, construction sites, and rental properties all rely on electrical devices daily, making regular PAT testing essential. Whether you’re a landlord, business owner, or facilities manager, understanding how often PAT tests are required can help you stay compliant, reduce risks, and protect both staff and customers.
At Anode Electric, we support London businesses with reliable, affordable, and fully certified PAT testing services tailored to commercial environments.

Common workplace appliances include:
- Kettles and microwaves
- Extension leads
- Computers and monitors
- Power tools
- Heaters and fans

Regular PAT testing helps London businesses:

- Reduce downtime caused by faulty equipment
How Often Should PAT Testing Be Done in London?
There is no single universal timeframe — frequency depends on risk level, equipment type, and work environment.
Here are recommended intervals for London workplaces:
| Environment | Equipment Type | Recommended Frequency |
|---|---|---|
| Office Buildings | Computers, printers, chargers | Every 24 months |
| Retail Shops | Till systems, portable heaters | Every 12 months |
