Energy-Efficient Appliances Guide

Where Your Energy Goes

Understanding which appliances use the most energy helps you prioritise upgrades and change habits. Here's the breakdown for a typical UK home.

Biggest Energy Users

• Electric heating: £500–£1,000/year
• Electric hot water: £200–£400/year
• Fridge/freezer: £50–£100/year (runs 24/7)
• Tumble dryer: £50–£100/year
• Washing machine: £30–£50/year
• Dishwasher: £30–£50/year
• TV and entertainment: £30–£50/year

Understanding Energy Labels

UK appliances use an A–G rating scale (updated in 2021). The difference between grades can mean £50–£100/year in running costs for large appliances.

When to Replace vs Repair

Generally, replace rather than repair if:

• The appliance is 10+ years old
• Repair costs exceed 50% of replacement cost
• The energy rating is D or below
• It's a high-use appliance (fridge, freezer)

Best Upgrades for Savings

Fridge/Freezer

Upgrading from a 15-year-old fridge to an A-rated model can save £50–£80/year. Since it runs 24/7, efficiency really matters.

Tumble Dryer

Heat pump dryers use 50% less energy than traditional vented dryers. Payback period is typically 3–5 years through energy savings.

Washing Machine

Look for high spin speeds (1400rpm+) which extract more water, reducing drying time. Also use eco modes and wash at 30°C when possible.

Smart Usage Tips

• Run full loads only
• Use eco/economy modes
• Air dry when possible
• Keep fridge coils clean
• Defrost freezers regularly
