Energy efficiency and ecological considerations

New freezers are graded by manufacturers on an Energy Rating scale of A (and A++ and A+) to G, with A++ being the most energy-efficient. These assessments are monitored by the Trading Standards Institute.

In any case, the running costs of freezers are low, typically about £25 a year, or less. Freezers are more efficient when full, as the bulk of frozen goods helps maintain a low temperature.

Nowadays, new freezers do not contain ozone-damaging CFCs (chlorofluorocarbons), and many are free also of HFCs (hydrofluorocarbons), which may contribute to global warming. Instead, they use the natural gas propane, a hydrocarbon that does not harm the ozone layer and makes minimal contribution to global warming.

When getting rid of your old freezer, see if the company supplying the new one can dispose of it safely for you; otherwise, contact your local recycling centre for advice.
