The EnergyGuide label on new refrigerators will tell you how much electricity in kilowatt-hours (kWh) a particular model uses in one year. The smaller the number, the less energy the refrigerator uses and the less it will cost you to operate. In addition to the EnergyGuide label, don't forget to look for the Energy Star label. A new refrigerator with an Energy Star label will save you between $35 and $70 a year compared to the models designed 15 years ago. This adds up to between $525 and $1,050 during the average 15-year life of the unit.

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.

Ask yourself a myriad of questions about your lifestyle (and that of your family), so it's as well to have as many of the answers ready as possible. Consider:

• who's going to be using the kitchen - is it just the cook or does everyone tend to congregate there?
• Do you keep pets who eat or sleep in the room?
• Do you need a table or will a breakfast bar suffice?
• More and more families are creating a living kitchen where there is not only a dining table but also some soft seating and a television.
• Would you consider building an extension or giving up a formal dining room to create a large kitchen/diner?
• What other tasks are undertaken in the room apart from cooking? Is it used for laundry, ironing, homework, entertaining?
