Hi, I recently bought a Bosch built in elec oven. According to the guy who sold it to me I can just plug it straight into a socket, no need for it to have it's own circuit. Is this correct and legal? Also I am worried that if a technician takes of the plug and wires it to the old oven circuit I might lose my warranty on the oven. Can anyone please help me with this. With the oven I also got a gas hob, which apparently I can connect to a small gas bottle that I can simply keep in a cupboard?
