    "There would need to be an RCD in your consumer unit which you can easily see if there is one. Do not confuse this with the individual MCB's (circuit breakers) Your cooker circuit may be a 32 Amp MCB and this may need changing to a different rating depending on your new cooker. Also the existing cable supplying the existing outlet plate will need need checking to make sure it is large enough to handle the current demand from the new cooker. The cable supplying cookers is normally 6 mm which due to something called 'Diversity'. Applying Diversity to cookers what you do is work out the current (Amps). For example for a 6KW oven this is the power.
    Current (Amps) = Power divided by voltage
    =6000 / 230 = 26 Amps. However, because of Diversity factors the oven will never draw 26 Amps.
    The way you work it out is:
    Take the first 10 Amps + 30% of remainder = 10A + 5A = 15 Amps. Add 5 Amps if there is a socket outlet on the cooker isolator switch = 20 Amps total.
    6mm twin & earth cable will easily handle the current draw fro the oven in this case.
    These are the things an Electrician will look at and if everything is ok and no cable or circuit breakers need changing then connecting new cooker is straightforward and will cost around £50 ( maybe a bit less or a bit more)
    If there is no RCD in the consumer unit then this will add to the cost perhaps significantly."
