The cooker is going to have to go, although last weekend's fix has improved it immeasurably.
There is a Belling range cooker which looks great and has good reviews, but they've given it a side opening door on the right which needs 60mm of clearance where we only have 35mm. Luckily I can cut an inch off an overhanging worktop and steal space on the left to move the cooker away from the unit on the right. Irritating, but better than paying another £100 for a Smeg cooker which isn't anywhere near as good (looks impossible to keep clean, and NO CLOCK!).
It will be nice to have a cooker with two smaller ovens (and a grill too) which heat up in 5 mins, rather than one mahoosive one which takes 20 minutes. Should save a fair bit of electricity.
