Photo's not too clear. Looks like a Chint box, but they usually have
translucent covers to the breakers. So what make is it?

30mA trip and you've got the hob, cooker and immersion heater on it?
Recipe for frequent tripping. As has been suggested, the very LEAST you
should do is swop that trip for a 100mA one.

You may actually be able to use a split busbar in that box, in which
case you could fit a switch-disconnect at the other end of the same row
and cut the busbar appropriately.

And there's actually a spare way in the top row of breakers which are on
a switch-disconnect.
