Pat Testing - Portable Appliance Testing

Many companies are still unaware of their duties to inspect, test and have the results recorded for their portable appliances on site. A portable appliance is anything with a plug attached to it, these can be low risk environments e.g. offices; medium risks e.g. shops and workshops; high risks e.g. building sites with 110v appliances and industrial kitchens.


The regularity of testing is determined by the type of appliance and environment it is in. We find incorrectly rated fuses, which we change FREE of charge, poorly wired plugs with breakdown of the insulation and all on our visual inspection prior to testing the appliance.


Many insurance companies now require proof of PAT testing before insurance is agreed.


Remember to get your company covered with Proactive Appliance Testing Ltd and be safe and tested.

2. The plug top will be opened to ensure that the flexible cable is secure in its anchorage and is correctly wired, that the fuse is of the correct rating for the appliance and is free from any sign of overheating and is in physically good condition.
3. The appliance will be inspected to ensure that it is in good working order, including ensuring that it switches off properly, and the casing/cabinet has no damage that could result in access to exposed live parts.
