Our cooker control unit incorporates a 13A socket but is too high (and directly above the cooker) to be of much use. I can access the cable under the floor and wonder if I could insert a 30A junction box (without cutting the cable) and run
2.5mm cable from there to a new 13A socket in a slightly more convenient position. I cannot run from the existing kitchen sockets since they are both spurs from upstairs (1969 house). The CCU has a 30A fuse for this radial - and no spare positions.Geo
