Additional consumer unit in domestic property breaker sizes?

[P-Courty]

I have a few questions about a couple of breaker sizes needed due to current draw and diversity.

In place already is as usual;
A main service fuse (100A)
25mm P&N tails to meter
25mm P&N tails from meter to CU
12 way CU split load

What has been done is a garage conversion to kitchen.
I was told they wanted a new CU for the kitchen area due to the 12 way being full and old (and strapped for cash).

I've been given a 6 way CU with 80A RCD, P&N 25mm tails & 16mm earth tail (customer supplied).

My plan was (correct me if I am wrong anywhere please) going to need additional items to complete.

1. Outgoing 25mm tails from meter to a 2 way CU with an MK 100A double pole main breaker (to protect service fuse).
2. From there 25mm tails to a 6 terminal henley block.
3. From the henley block 25mm tails to new 6 way CU and 25mm tails to existing CU.
4. 16mm earth to each CU from MEB.

Now this is were I could do with a little help on breakers.

The new board only has the RCD, do I need a main breaker in there? As in an 80A main and 63A 30mA RCD?
The circuits put it are a 32A kitchen ring final and a cooker circuit (for some reason in a 2.5mm t&e) I did question that and they said the kitchen fitters said the 2 single ovens are capable of being on 16A radials and the hob (not heard that before) so I may need to upgrade the cable size for that when I find out the kw of them (think it will be a must). This is what is confusing me on the RCD and main breaker sizes I should choose as i'm not completely sure what the draw is going to be.

Any help on all of this would be very much appreciated as they want this completed by the end of this week.

Thank you in advance for any help and advice given.

How am I conning you, I am asking for help off you if I was regular Joe Blogs I would just go ahead and do it. I got all my certificates back in January 2012 I've been labouring since then (2 years 11 months) basically 3 years like I said. In that time I had a lot of family issues I went through lost everything and hit depression and am now in financial difficulty so sorry if this the words breaker and switch got mixed up in my head during all of this.

I've come here to ask you guys for help because surely you've needed that in the past. And if this is childs play then why are you not helping me and just tearing me back down to were I used to be I thought coming to you guys could help me out.

It looks like you have never been living on every penny you get and own your own houses and have vans well to me a penny is a lot and as for a car well thats a luxury to me and my bloody pedal bike. I thought you guys could help me out but guess I was wrong. I have my A's back from school and distictions from college I worked my arse off to be told I was over qualified for certain jobs so can't even work on a till at my local Asda because of that so sorry for asking for help!

The con comment was not directed at you, it was with regards the NIC and other scams requiring someone like you who trained under the 17th to do the 17th course in addition.


I've been there and done that!
This time last year I was down to only eating every other day, so yes I have been in the situation of living off of every penny I can get.
I am still stuck living with my parents as I cannot afford a place of my own.
And yes I have been diagnosed with depression.

If you have genuinely worked your arse off and got learned the trade then how come you need to ask such basic questions?

Electricity can and will kill people or burn down their houses if you make the most simple of mistakes.
