You're using pounds, so you're in the UK - you have many more watts in a standard outlet than in the US. An electric kettle in the US takes over twice as long as one in the UK. Now try using that to cook a meal...
This hob uses US 240v outlets if available (I suspect the nominal 10kW is not available otherwise, but I don't know) and surely you have electric ovens too anyway?
A standard outlet as for a kettle though, yeah, absolutely. And in fact even in the UK oven/hob is usually on its own 32A circuit, which if you P=IV suggests 8kW is probably a common rating for a reason.
