The cost of ignoring it
What an inspector finds when there is no PAT record
Risks if left unchecked
- ●Internal cabling pinched in a flex grip, invisible until insulation resistance is measured.
- ●Damaged plug pins still in service after being kicked out of a socket.
- ●Class I appliances with broken earth continuity, the case becomes live on first fault.
- ●Extension leads daisy-chained to feed unrated loads, a classic ignition source.
Common mistakes
- ●Sticker-only PAT visits with no insulation resistance readings recorded.
- ●Testing only the appliances on the day, missing tenant-owned items not declared.
- ●Testing without an asset register, no way to prove what was and wasn't checked.
- ●Skipping the visual inspection because the electrical test 'passes'.
Wales HMO PAT testing is mandatory under the 2022 regulations. No record = no defence after an incident, and an open door for licence enforcement.
