Thanks for your advice Stefek.

OK so in summary, I have done some further checking on devices to see
what the draw will be

Hot Tub = 1.5KW Thermostat controlled and well insualted
Toaster = 950W Rarley on
Coffee = 1.2KW Rarley on
Kettle = 2KW Rarely on
UFH (Kitchen) = 2KW
F/Freezer = 300W

So from my math when all these devices are on (They never will be) the
total draw is 7.95 KW = 31.8 AMPS

So taking this figure and taking some advice I was given from this
forum regarding wiring a cooker and a hob together on the same circuit
I should be ok allowing for diversity. Just like to add here that
Stefek you stated you wouldn't do this and that I should wire the hob
onto a seperate circuit. I'm not stating here that you were wrong
simply that some people tend to me more cautious than others, which
when dealing with electicity is probably a wise thing to do.

Basically in this previous post it was stated that because my cooker
and hob would never be on at the same time, meaning all elements, then
a 9KW draw would be ok. I actually did put all elements on and the MCB
didn't even trip. I didn't however leave these on for an extended
period of time though.

In addition to this, if it was an easier job than it will be to wire
these seperate circuits in as you suggest then I would do it without
question. I have floorboards upstairs and the previous occupiers have
built units over where the consumer unit is so this will be a hellish
job and if I can get away without wiring in seperate circuits then I
would like to.

Is Owain or Lurch around, I would like a second opinion please, they
stated the oven and hob could go on the same circuit which turned out
to be correct. However they did talk about cable lengths too so maybe
this will come into play in my scenario.

BTW the hot tub is protected by a 30MA RCD and the company who
installed it are basically the main players in the hot tub market and
are not cowboys, also my UFH guy is not a cowboy either he also works
for a very reputable company. It makes me laugh that people
automatically assume everybody is a cowboy, now ask me about my kitchen
fitter, he was a cowboy!

Thanks for your contribution Dave.
