new oven

Need old oven replaced with new oven that we have purchased, not sure if it is a simple change over, old oven is wired in with four wires and two 15 am fuses. new oven is a 3 wire instillation with a 32 amp fuse required. Want an idea what is possible if we can directly swap out and cost associated. If rewire needed the oven is about 14 meters from fuse box. Switch and fuse will be needed. wont need to be fed through wall as there is a cupboard next to the oven which backs on to the kitchen so can be fed through to a new switch with the switch box fitted into the wall of the cupboard so direct accesses to all wiring etc.
