    Hi all,

    I have just bought a house and currently removing the kitchen to replace and fit oven/hob.
    We would like to install a gas hob and electric oven (integrated)
    The kitchen does not have a dedicated cooker circuit.

    Below is a picture of what we have. My question is.... if I got an electric oven 13A below 3000kw could it have a 3 pin plug fitted to the flex (provided we buy an oven with cable) and then be plugged into one of the many sockets we have!? I have looked online and found lots of conflicting info.

    For info the fused spur on the wall seems to control the plug sockets to the left of the picture which a water feature in the gardens runs from!!

    Any help you can give would be very appreciated, we just want to get an oven ordered but dont want to get the wrong thing or get an electrician in for something that cant be done.

    Thank you all :)

    There are two problems with the 13A plug, one is the fuse gets hot with extended use, but an oven may use 3kW on switch on, but then starts to cycle so not really a problem. The other is with a ring final the parts near the consumer unit can be overloaded, however the oven takes maximum power for such a short time again not really a problem, but as a result BS7671 has in the appendix that fixed appliances over 2kW should have a dedicated supply, so technically the washing machine, tumble drier, dishwasher, and oven should all have dedicated supplies, but I am sure you realise the only one always given a dedicated supply is the immersion heater, there is a case for tumble drier and washer/drier having a dedicated supply but even that is rarely done.

    So in the main, there is always an exception, there is no problem with an oven on a 13A plug, but I hope from the above you can see why some say there is.

    Hi Eric,
    Thank you for this, yes, I understand and can see why there are many different answers around. What you have explained does help me :)

    Thank you.

    Don't see why the double socket needs to be supplied via an FCU. The plugs have fuses after all. What is the other socket hanging on wires on the right used for? It might be better to use this one for your oven.

    In practice it is quite difficult to overload one leg of a ring. You would need to take a full 32A within about 15% of the end of a ring to overload one leg using 2.5mm cable rated at 27A.
