I have an electric Cooker 55cm wide that I installed when I fitted new kitchen units some while ago. I left a gap 60cm wide between the units either side of the cooker to allow air space.
I now find it very difficult to get a 55 cm cooker to her indoors liking. I might be just able to squeeze a 60cm cooker in but it will be touching the cabinets either side. Will that be OK or must there be a gap?
