Electrics 1980s style

I have just been informed by a tennant that the property she rents has out of date electrics.
She has just had a baby - and one of her sisters friends (supposedly and electrician) has informed her that all of the electrics are out of date and potentially dangerous
I've been given a list of things she would like changing / upgrading

1. New Consumer Board
2. Mains tails to meter
3. New mains earth
4. New 10mm earth to gas meter
5. Install 10mm earth to water meter
6. Replace 7 sockets to switch sockets
7. Block out switches above cooker
8. Provide 17th Edition Electrical Certificate

Now i know nothing about electrics - is this request reasonable ?
Obviously - I want the house to be safe - but i would have thought that a house built in the 1980s wouldnt have dangerous wiring.
