Ok it’s rubbish
That was last year new regulations came into force in January that potentially changes everything it can be mitigated but that’s down to the electrician carrying out the work under agreement with the client.
18th edition IEE regulations which came into force in January and especially changes domestic premises or to quote “premises with sleeping quarters “ there’s a lot of discussion about it within the industry at the moment AFD’s which it specifies are around £130 each

So 10 circuits with one on each circuit .
Just to clarify I am an electrician by trade although I don’t touch domestic it’s caused a big debate with engineers I know on new apartment blocks that are being designed at the moment due to increased cost, size and the fact that regulations are written in a way that someone has to state the fact why they’re not needed and potentially leave themselves open to a future law suit. I believe it’s come about partly because of Grenfell (sp)
