Just taking the plug off the end and wiring it into the socket isn't going to help. The wiring and the RCD in the consumer unit needs to be specced correctly. For instance I have a high power induction hob in my kitchen. It is on it's own circuit with heavy duty wiring and a 45 amp isolator switch. Rather than being fused at the isolation switch, it is on it's own RCD at the consumer unit. It can draw enough power to melt a 13 or 15 amp fuse, so it can't just be wired like other electrical items.
Other items are on their own ring just for the kitchen, and they are each fused at their own isolation switch, which is a totally separate ring from the induction hob. Some things are on plugs (dishwasher, washing machine, fridge), some things (extractor fan, hob) are wired directly into the circuit with no plugs.
You really need to get a decent electrician to spec a new ring and run a new wire to the consumer unit. This can get expensive if (for instance) you have no space on your consumer unit or have a very old one that needs replacing. Running a new cable also depends on where you need to run it and what access is like. Obviously it's easier to do if you're installing a new kitchen and the room is stripped out, compared to running it in an existing kitchen.
