In the statistics on appliance returns, the leading reason is neither a fault nor disappointing performance. It is that the thing does not fit.

Beyond the appliance’s own dimensions, three things are routinely overlooked: the width of the front door and hallway, the position of existing water and power connections, and the load-bearing capacity of a balcony or wall unit.

Which specifications matter

On specifications, concentrate on the few that relate directly to how you will use it, rather than reading the whole sheet. For a fridge, usable capacity and compartment layout; for a washing machine, drum diameter and spin speed; for air conditioning, room size rating and efficiency class.

  • Step one: measure, including door width, services and load-bearing
  • Step two: read only the specifications relevant to your use
  • Step three: compare prices and confirm whether installation is included
  • Extended warranty: better value on anything with a compressor

On extended warranties, the after-sales staff we spoke to advise judging by category: anything with a compressor is expensive to repair, so cover is worth more; small appliances usually are not.

The final cost most often forgotten is installation. Basic fitting is free in some categories, but drilling, extended pipework and removing the old unit are usually charged separately.
