If the cable is 2.5 then the MCB could be upped to 20 Amps.
However, ovens and other appliances should ideally have their own dedicated circuit if they are rated over 2kW.
If you look at the time/current characteristics of a type B 16amp mcb in the regs you'll see that it takes 80amps for it to trip in less than 5 seconds and that 25amps will take about 1000seconds.
Jasons right, you should not connect a fixed heating load of over 2kw to a final ring circuit.
Also, how can a thread that is only a row of dots last so long?
