Updating and making safe an electrical install from 1973

[elbow]

Hi,

I have bought a house built in 1973. Came of course with a Electrical CoC but the state of the DB does not fill me with happiness and confidence.

I’d like to get it right.

Here’s a picture:



I’m looking for opinion - myself I’d like to replace all the old breakers with new 13mm units.

1. Separate main switch and breaker to a combined dual-pole breaker
2. Two RCDs - one for lights, one for everything else? (will I be sorry putting everything on earth leakage?)
3. 4 light circuits (10A)
4. 1 send to the pool db (15A)
5. 3 plug circuits (20A)

Or something like that.

But I’m looking for advice before discussing with my electrician.

Thanks,
Elbow
