Yes, here in the UK appliances that work off a standard circuit and can be plugged into a standard socket (so 13A max) come with a cable and fused plug. This applies to washing machines, tumble dryer, dishwashers, etc. On the other hand, appliances that require too much power (more than 13A) e.g. double oven and some hobs, or cookers do not come with anything and must be wired with an adequate cable, circuit, etc. In general circuit, switch, etc. should already be installed (otherwise you're majorly out of luck) and you only need to buy a 1-1.5m length of adequate 3-core rubber flex to connect your new oven. It's very simple to do as long as you know how to strip a cable and use a screwdriver.
