Check the capacity. 'Standard' 60cm wide dishwashers can take 12, 14 or 16 place settings, whilst slimline 45cm models may cater for 7, 8 or 9 place settings. Compact dishwashers tend to be 45 cm wide and can be placed on the worktop or built in, depending on the model. They may take 4, 5 or 6 place settings.

Buying this "service deal" can be expensive but if you feel happier knowing that you are protected from breakdown for a few years, shop around insurance brokers to see how prices compare.

The optimum location for the cook top is along an exterior wall, rather than on an island or peninsula. With a stove on an outside wall, it's easy to install an effective hood and ventilation system, essential to expel grease, smoke and combustion gases. The stove or cook top needs a 21- to 30-inch overhead clearance so cooks can readily see and access rear burners and the ventilation system can do its work efficiently.
