I still think splitting the ring into two radials is a bodge.Why? I personally think it's a logical, safe solution.
It just seems a shame to totally refurbish a house, but not properly sort out the wiring.
As you say, it's your house. Just don't come and complain if ever you sell it and a surveyor picks up on the state of the electrics and the buyer then beats the price down because he thinks it needs a rewire.
Why would the electrics be in a state? 2 RCD protected radials instead of 32A ring, where's the mess?
If you really are totally refurbing the place,
then there will never be a better time to sort the wiring properly. That's what I did on my last house. As each room was re done, it was re wired. It meant for a while as I worked through the house it was a mixture of old and new, but it was all planned and by the time the whole house was refurbished, it all had new wiring.
Best of luck whatever you decide.
Thank you
