Look on the plate on it for the loading of it. A 13amp plug is good
for just over 3KW, but I wouldn't plug that much into a ring main if
it will be used a lot, it would be better to use the proper cooker

If you can advise the full loading of the oven then someone can give
you chapter and verse on the proper procedure.

Most ovens nowdays come with a 13A plug on them and are intended
to be plugged in to a 13A outlet. However, a double oven is likely
to exceed this and may need wiring in. You will need to check this
with each model you consider.

I would also suggest you think carefully about a double oven. The
compromise with them is that even the larger oven tends to be quite
small (unless the whole thing is enormous), and in many cases
afterwards, people wished they bought a single oven unit with a
larger oven instead of the second oven which is almost never needed.
For the very occasional second oven use, you might consider also
having a microwave with convensional oven heating, which is what I
have done. I think this is much more flexible than a cramped double
oven.
