    Lights and sockets on one circuit?

    Hi guys. I had an inspection yesterday, where the lighting and sockets are in one circuit for each floor. There are 3A fused spurs for the lights. I also need to replace the consumer unit with 18th edition one. How would you code that? Any advice on the consumer unit would be appreciated. Thanks
