I'm thinking clearance warehouse 2nds no offence intended.

I've checked the technical info on the oven and it says its 40A, the main fuse Is a 30A is this an issue

not really as the oven will not draw anywhere near 40A due to diversity ( that's because you won't hav all elements on at the same time and the stat/s cut them out. a 30A fuse will withstand 40A for somewhere around an hour.
