lets all be honest here , looking at that pic , 3036 fuses probably getting up to 40 years old it looks like a rewire all day long but a quick half an hour by any decent spark will verify this.!With the greatest respect to all you guys, I wouldn't have to carry out a full EICR before deciding somewhere needs rewiring.
I know it's hard to find the right electrician, as some will inevitably be touting for work, but a visual and some basic testing by a good and experienced electrician will give you a very good idea whether it's that bad.
