Because the use of portable electrical appliances of any kind places a requirement on you to ensure it's safe to use, almost every business will have PAT Testing obligations. PAT Testing is an important legal requirement, and without up to date certification your insurance could be invalid. The frequency in which your appliances need PAT Testing will depend on what the appliance is, how it's used, how often it's used, and what industry you're in. If you're unsure of how often your appliances need testing, get in touch with our customer service team today.
