  • Defrost freezers regularly — ice buildup increases energy use by 15%
  • Cook with lids on pans — reduces cooking time and energy by 25%
  • Use microwave for reheating — 80% more efficient than ovens for small portions

Hot water savings: Slash bills by £300+ annually

🚿
Take shorter showers
Reduce shower time from 8 to 4 minutes. Install a shower timer or play 4-minute songs as reminders.
Save £70/year
💧
Fit water-saving showerheads
Low-flow showerheads reduce water use by 40% while maintaining pressure. Cost £15-40.
Save £120/year
🔧
Fix dripping taps immediately
A hot water drip wastes 5,500 litres annually. Usually fixed with a £2 washer replacement.
Save £35/year
Use shower timer
Set a 4-minute timer or use apps that play music for optimal shower length. Make it a family challenge.
Save £85/year

Hot water system optimization

  • Lower water heater temperature — 60°C is hot enough for most needs
  • Insulate hot water pipes — saves £15-25/year and provides hot water faster
  • Use bowl for washing up — more efficient than running hot tap continuously
  • Install tap aerators — reduce hot water flow by 30% without affecting pressure
  • Time your hot water — heat water when you need it, not 24/7
  • Take baths occasionally — a 4-minute shower uses less hot water than a full bath

Smart technology & monitoring (save £200+ annually)

📱
Use smart meter displays
Real-time energy monitoring helps identify wastage. Most households cut usage by 10-15% just by seeing it.
Save £220/year
Switch to Economy 7 if suitable
Cheaper night-rate electricity. Good if you use dishwashers, washing machines, or electric heating overnight.
Save £180/year
🏠
Use smart plugs for monitoring
Identify energy-hungry appliances and control them remotely. Set schedules for non-essential devices.
Save £95/year
🌙
Charge devices overnight
If you have Economy 7, charge phones, laptops, and electric vehicle batteries during cheap rate hours.
Save £45/year

Room-by-room energy saving guide

Living room & lounge

  • Use zone heating — only heat rooms you're using
  • Lower TV brightness — reduces energy use and extends screen life
  • Use energy-saving modes — most modern TVs have eco settings
  • Switch off game consoles — PlayStation and Xbox use significant standby power
  • Use natural light — open curtains during day, position seating near windows

Kitchen efficiency

  • Match pan size to hob ring — using wrong size wastes 40% of energy
  • Keep fridge away from oven — heat sources make fridges work harder
  • Use residual heat — turn off electric ovens 5-10 minutes early
  • Boil only what you need — overfilling kettles wastes energy and time
  • Use pressure cookers — 50-70% faster cooking times

Bedroom optimisation

  • Layer bedding instead of heating — extra blankets are more efficient than higher thermostat
  • Close bedroom doors — keeps heat in or out as needed
  • Use thick curtains — insulation effect saves 10-15% on heating
  • Unplug chargers when not in use — phone chargers draw power even when phone isn't connected
  • Use low-energy night lighting — LED night lights use 90% less energy than leaving main lights on

Bathroom water & heating

  • Use basin for teeth brushing — running tap wastes 6 litres per minute
  • Install heat recovery fans — capture heat from shower steam
  • Use bathroom rugs — warm floors reduce need for heating
  • Fix toilet leaks — can waste 200+ litres daily if inner mechanism is faulty
  • Use exhaust fan timers — run only long enough to clear moisture

Seasonal energy saving strategies

Spring & summer cooling

  • Open windows at night — cool air flushes out day's heat
  • Close curtains during peak sun — prevents greenhouse effect
  • Use fans instead of AC — ceiling fans use 90% less energy than air conditioning
  • Cook outdoors when possible — grilling avoids heating the house
  • Service air conditioning — clean filters improve efficiency by 15%

Autumn preparation

  • Check heating system — service boiler before winter demand
  • Clear gutters and drains — prevents water damage that wastes heat
  • Seal exterior gaps — caulk around windows, doors, and pipe entries
  • Store summer appliances — unplug fans, dehumidifiers not needed in winter
  • Switch to winter curtains — thicker fabrics for better insulation

Winter heating efficiency

  • Maximise solar gain — open south-facing curtains during sunny days
  • Use door snakes — stop draughts under doors with fabric tubes
  • Wear warm clothes indoors — jumpers allow 2-3°C lower thermostat setting
  • Use hot water bottles — personal warming instead of whole-house heating
  • Keep active indoors — exercise generates body heat naturally

Monitor your progress: Track savings effectively

To maximise energy savings, track your progress:

  • Read meters weekly — spot unusual usage patterns quickly
  • Compare monthly bills — adjust for weather differences using degree days
  • Use energy apps — many suppliers offer detailed usage breakdowns
