PAT Testing Frequency Table: Notes:
1	The formal visual inspection may form part of the combined inspection and tests when they coincide, and is to be recorded.
2	110V earthed centre-tapped supply. 230V portable or hand-held equipment is required to be supplied via a 30mA RCD and inspections and tests carried out more frequently.
3	For some equipment such as children’s rides a daily check may be necessary.
4	By supervisor/teacher/member of staff.
5	Equipment provided in hotels rooms is equipment used by the public. Equipment in hotels (in table) is considered to be equipment in hotels used by the hotel staff.
	•	It is normally not necessary to test new items of equipment as the manufacturer has already tested them.
	•	The information on suggested initial frequencies given above is more detailed and specific than HSE guidance, but is not considered to be inconsistent with it.

		S	Stationary Equipment
		IT	Information Technology Equipment
		M	Movable Equipment
		P	Portable Equipment
		H	Hand-Held Equipment

Through our years of experience we have found the frequencies of PAT Testing suggested give a good working program and are sufficient to ensure the safety of electrical appliances, however it has to be emphasized that the frequency of testing should be determined by carrying out a risk assessment which Osborne & Collins can conduct for you free of charge.

PAT Testing Frequency Requirements - Insurance Companies & ISO Standards

It also has to be stated that many insurance companies and ISO standards specify a requirement to have portable appliance inspection and testing carried out annually.

* PAT Testing from 79p, subject to the number of tests
