We're looking at a new dual fuel cooker. There's no dedicated cooker

Has to go? You could install a circuit for a cooker to the kitchen.
This would allow future occupants a choice over the sort of cooker
they use. The supply should be at least 30/32A, but being
old-fashioned I prefer 45A (which means expensive cable and
equipment compared to the lower rating). You can do the work
yourself in Scotland, provided you are "a suitably qualified
electrical engineer" able to design, install and test it to the
Wiring Regulations. You may need to be able to defend yourself in
court if you do so, the alternative is to get someone to do it. Down
south things are different.

What follows is from memory. I have not looked it up and it is worth
exactly what you have paid for it. Someone may correct me.

Large cooking appliances must be provided with an isolating switch
within 2m of their location. That is because, even if it can be
moved, it is considered to be fixed equipment.

A 13A fuse will not blow rapidly at the current you have given.
However, it (and possibly bits of the FCU) will run warm, perhaps
rather warmer than designed. Even if you don't eventually set
something on fire it is likely to discolour.

In ye-olden days it was a standard arrangement to connect fixed
equipment to a ring main with a circuit breaker not exceeding 16A.
However, the connection of large loads to ring circuits has been
discouraged for a long time. Partly this is because it robs the
circuit of capacity for other loads. It may be that in your
particular circumstances you can justify such a connection, but you
will need to document it and I would only do so as a very last
resort. You would then use 20A rated equipment from the circuit
breaker to the cooker outlet.

Is that true ? I've been saying no to all sorts of odd jobs because
of Part P, and $%*&&&* knows I could do with the money.

They have a new edition of the 'electricians guide to the 16th'
in the library wih a secion on part P too if anyone's curious.

That applies only in England and Wales. It is a faulty
implementation of what has been the case in Scotland for a very long
time, giving legal recognition to the Wiring Regulations.
