Student Accommodation - Hidden Second Elecrical Isolation Switch
England student accommodation - our oven wasn't turning on so we messaged our landlord about it. We already checked the fuse box / circuit breaker for the house, and the main isolation switch for the oven (which is above the countertop).
The landlord sends round an electrician who literally takes out the entire oven before finding the switch in the attached photo, that is off. The switch in the photo is hidden at the back of the top shelf of a cupboard underneath a countertop, so isn't really visible if you're using the cupboard normally, and clearly just got knocked by something being pushed to the back.
The landlord wants to charge us £45 for the electrician's visit, saying that we "unplugged the oven". It was just turned off, not unplugged (we were there when the electrician was around).
Do we have to pay given the switch is literally hidden and we had no idea of its existence?
