Cookers go hand in hand with extractors; find out your options.
Nowadays most kitchens will separate the oven from the hob, although hobs can be integrated in a range or simpler cooker combination. When separate from the oven, they are usually fitted directly within the worktop.
The choice is then between electric or gas powered. The controllability of gas has long given it an edge over other types, but this position is being seriously challenged by the new generation of induction hobs which work in a similar way to microwaves and can boil a pan of water in four minutes.
