Cooker Cable

Hi,
I bought an new Electrolux cooker which arrived all bright and shiny yesterday.........but no flex supplied????
The manafacturers instruction just say "a suitable cable" - terrific.
Its a free-standing double oven with ceramic hob rated at 10kw-11kw. What flex do I need to buy. I have already installed the house wiring on a 45A radial feed with 10mm/2 cabling but I cant find a 45A heatproof flex in the shops.....help!

normally people just use T&E to connect cookers, they don't tend to get moved too much and the larger sizes of T&E are stranded anyway so less risk from breakage than with the smaller sizes.

as above 10mm t/e from cooker outlet to appliance.
