Portable Appliance Testing (PAT)

PAT is the legally required testing of each portable electrical appliance in a premises.

ESOS Energy is a leading expert in risk assessment and Portable Appliance Testing (PAT) – specialised processes which ensure that electrical appliances comply fully with UK legislation and where necessary, are tested and certified.


Through our fast, efficient and cost-effective risk assessment and portable appliance testing (PAT), we gives businesses total peace of mind, knowing they have taken the right steps to ensure equipment is safe for use – both on and off site. The process is recognised by the insurance industry and without up to date risk assessments or test certificates, your insurance could be invalidated.

Health & Safety

The Health & Safety at Work Act 1974, the Management of Health & Safety at Work Regulations 1999, the Electricity at Work Regulations 1989, the Workplace (Health, Safety and Welfare) Regulations 1992 and the Provision and Use of Work Equipment Regulations 1998 require all electrical equipment used in, or associated with, places of work to be assessed on a regular basis by a competent person.
