Depending on the equipment involved they could be trained to check themselves? PAT testing can involve just a visual examination, plus removing the plug cover and that checking the wiring is correct. Not all PAT testing involves fancy equipment nor do you have to be an electrician - merely competent to a level apropriate to what you are doing.

Depends on what type of homeworking your people are involved in. If it is just "office" type work around using a PC the recommended frequency for checking is 5 years if memory serves. Other than user checks before each use - why would you need to do anything more. I am with Murray - simple instruction on how to carry out a user check should suffice.

Have to disagree with Pikeman above. I would positively discourage people from removing plug tops. They've no real reason to do so, and this merely increases the likelihood of the ill-informed doing something silly. If you're only talking IT equipment, a 5 year cycle is more than adequate. Add PAT testing to maintenance schedules, or be extra bold and don't do it at all. There is no "legal" requirement other than to maintain equipment in safe condition.

Regarding removal of plug tops, most IT equipment comes with sealed plugs that cannot be opened up. When we supply equipment to our customers (for skin condition monitoring) the mains leads all have sealed plugs. Chris

The usual arrangement in domestic tenancies is that the landlord is responsible for safety checks on all equipment supplied with the accommodation but not for the tenant's own equipment.
