Based on average annual consumption per appliance and Electric Ireland unit rate of 34.75c per kWh (Urban 24-hour meter, VAT included). Actual consumption may vary depending on appliance model, usage patterns, and energy rating.
Do Electric Showers Use a Lot of Electricity?
While a 5-minute shower costs approximately €0.36, consumption increases significantly when multiple household members shower twice daily.
Tips to lower energy consumption:
- Turn off the shower while washing hair and body, then turn back on to rinse
- Lower shower temperature, as hotter water requires more energy
- Set an alarm for less than 5 minutes to ensure efficiency
- Regularly clean shower heads to remove limescale buildup in hard water areas
Does a Kettle Use A Lot Of Electricity?
Kettles are energy intensive because they heat quickly. Although boiling takes approximately one minute, frequent use accumulates costs annually.
Tips to lower kettle costs:
- Avoid overfilling, as you waste energy and money heating unnecessary water
- Use the volume guide to measure required water amounts
- Invest in a smart kettle allowing lower temperature settings
- Use the microwave to reheat water

How Do I Calculate the Consumption of My Appliances?
Two methods are available: using a smart meter or investing in an electricity measuring socket.
Smart Meters
Irish homes with installed smart meters can use consumption data to identify costly appliances. Compare usage figures across different timeframes (daily, weekly) to determine individual appliance consumption. For example, skip using a tumble dryer for one week and compare consumption figures to assess its impact.
Electricity Measuring Socket
An electricity measuring socket is an adapter measuring appliance energy consumption. Note daily and weekly consumption figures, then calculate estimated costs using your unit rate. These devices cost approximately €35 and are available at Irish electronics stores.
How Can I Lower The Cost Of My Appliances?
Identify which appliances cost the most first.
Most Expensive Appliance Checklist:
- What does it do? (If it heats something, it's more expensive)
- How often do I use it? (Every day? Once a week?)
- How long do I use it for? (A minute? An hour?)
- How old is it? (Older appliances are less efficient)
- What is its energy rating? (Less than C costs more)
I Know Which Appliances Are Most Expensive. Now What?
While some expensive appliances are essential, their impact can be reduced through:
- Switching to nightsaver or smart meter price plans with lower night rates
- Programming expensive appliances to run at night
- Investing in new, energy efficient models
- Being more time efficient with showers and washing machines
- Installing smart plugs to automatically turn off expensive appliances
- Purchasing new appliances with A or B energy efficiency ratings

Behavioural Changes
- Turn off radiators in unused rooms and close doors to prevent heat loss
- Purchase a draft blocker for exterior doors to prevent heat escape
- Use electrical tape to seal window gaps and cracks
- Use residual heat from ovens and cookers to heat your kitchen
Investment in Home Upgrades
- Heat pump systems
- Attic insulation
- Wall insulation
- Heating controls upgrade
- Solar PV panels
Grants through the Sustainable Energy Authority of Ireland (SEAI) are available for home heating upgrades.
