We're hoping to move into an Edwardian house. Homebuyers says 'get an electrical inspection'. Hasn't made an issue of it, just something surveyor advises. House has new kitchen - 3 yo - and new lights, and newish electrical shower, so I'd assumed wiring probably ok (current owner lives there and clearly uses all these things daily). Is it the case that you have to rewire from time to time with old houses? We never have with our current Victorian home but only been here 10 yrs.
