Making choice for Main supply cut out upgrade???? 80amp or 100amp

[Robinson]

Hi guys just scratching alittle on this on as far as max demands concerned.

Got extension in house, curenntly has 60amp main cut out. 7 way board. Asked N.Power to come fit Iso and upgrade cut out too 80amp
INC.
1x 40 amp. shower
2 x 32 amp. rings
1 x 6 amp. lights WHOLE HOUSE ! eeeeeek
1 x 20amp. bolier
2 x spare

They having Big extension loads new circuits.

Wanting 16 amp Radials for all individual Kitchen apps
INC.

Fridge large double - 16amp supply
freezer large double - 16 amp supply
DW - 16 amp supply
washine machine - 16 amp supply
Boiler (new system) - 16 amp supply
Also 2 x sockets and a Spur in dining. (Tv and floor lamps) - 16 amp supply

Then also

2 x 6amp lighting circuits
1 x 32 amp kitchen ring. (above work surface sockets)
1 x 10.5Kw shower (this makes two in house both same rating)
1 x 7.5Kw Cooker range

the n plus all old circuits.
they may go for $$$$ all Rcbo's but not sure yet prob just Dual board LARGE 18way

My question is after doing max demand and diversty. i am Way over even 80amps

the main thing is the two showers. i dont doubt for a min these WILL be in use at same time. in morn, plus kettle and cooker im sure. it propa working family. 2 kids..
But thing is with each of these showers i have to take 100% fl. (OSG TAb1b)
that alone is 91amps.

So as i stated at beginning i at first requested a 80amp with N.power, but now these two showers are in equation im bit stumped. surly its got to be 100amp. but even then its tight any idea s?
they said they would do the 80amp and Iso for free , wondering how much 100amp would be as the carrier would need changing too..

i know it bit of a long one, but any ideas welcome

thanks guys

100A usually free if you can get them to do it, I was told recently some areas wont upgrade unless problems with cut out fusing under load.

well cool thats good to know. They recent had their 60 amp blow for no appart reason, woke up in morn had shower and power went. N.power came out replaced and just said "it happens". thats it !........Still its just the demands im concerned about, on a 80amp.

If you can get a 100A fitted go for it. Why go part way to solving the problem.
