I used to be meticulous about unplugging mine overnight as it was said to be a possible fire hazard. I don’t do it now due back problems.
My son in law is a firefighter and as well as tv he unplugs every kitchen appliance overnight. Microwave, toaster, kettle, dishwasher, washing machine etc. He said he’s attended house fires too many times that have been traced to a home appliance.
I know he’s right but it’s annoying sharing holiday accommodation with him when you’re first up and switch the kettle on only to discover 10 mins later it’s turned off at the wall!
Your SIL is right - the Grenfell fire started with a faulty fridge
