Well I agree quality. I can see their advantage.Induction hobs are the future
Easy clean being one. To get the rated supply through the house would be a no no. I've not priced yards and yards of armoured cable rated at 48 amps
The hobs we've looked at are higher rated than 32 amps. I'd get a qualified electrician to connect at hob and consumer unit and install the isolation switch. Just to satisfy the testing regs. And certificate. I'm 73 I recon a new gas hob will last me out. Mind my wife wouldn't appreciate me throwing away her non magnetic pans if I did go induction!!!!
