How to save electricity: smart ways to cut costs

Reducing electricity bills is a priority for many UK households. The good news is that taking control of your energy usage doesn't have to mean feeling deprived; instead, it's about making smart choices and optimising how you use electricity. The average UK home uses around 2,500 kWh of electricity per year, and with electricity costing 26.11p per kWh for an illustrative Direct Debit household on the Ofgem Price-Cap default tariff for 1 July to 30 September 2026, even small changes can lead to noticeable savings. This guide offers practical, actionable steps to help you manage your household electricity consumption effectively.

Understanding your home's electricity usage

The first step to saving electricity is knowing where it goes. Many UK adults struggle with high electricity bills because they don't know which appliances consume the most power or how their daily habits impact overall usage.

What uses the most electricity?

Appliances that heat, cool, or run constantly are typically the biggest electricity consumers in a home. This includes:

• Wet appliances: Washing machines, dishwashers, and tumble dryers account for a significant portion of energy bills due to the power needed to heat water or air.
• Refrigeration: Fridges and freezers are always on, making them constant energy users.
• Heating elements: Ovens, kettles, toasters, and electric showers are high-draw appliances when in use.
• Home electronics: While individual devices like televisions (TVs), laptops, and games consoles might not seem like much, their collective use and standby consumption add up.

Reading your smart meter data

Smart meters are a powerful tool for understanding your electricity usage. They provide real-time data, allowing you to see exactly how much electricity you're consuming and when. This transparency helps identify peak usage times and pinpoint energy-hungry appliances. Many energy providers offer apps that integrate with smart meter data, giving you even greater insight and control over your energy habits. Considering a smart meter installation can significantly enhance your ability to track and manage energy.

No-cost ways to reduce electricity

Some of the most effective ways to save electricity don't cost a penny; they simply require a shift in habits.

Behavioural changes for immediate savings

Simple adjustments to your daily routine can make a big difference:

• Turn off lights: Switching off lights when you leave a room can save around £7 a year.
• Unplug standby appliances: Appliances left on standby can still draw power, known as 'phantom load'. Turning them off at the wall could save you around £60 a year.
• Adjust your thermostat: Reducing your thermostat by just 1°C can lead to significant savings on heating bills.
• Boil only what you need: Overfilling the kettle wastes electricity; boiling just the right amount of water could save you around £13 a year.

Optimising appliance use

Using your appliances more efficiently can also cut down on consumption:

• Full loads: Only run washing machines and dishwashers when they are full. Reducing washing machine use by one load per week could save £26 a year, and filling your dishwasher could save £10 a year.
• Lower temperatures: Wash clothes at 30°C or lower, as heating water consumes a lot of energy.
• Air dry: Avoid using a tumble dryer when possible; air drying clothes saves considerable electricity.
• Defrost freezers: Regularly defrosting your freezer helps it run more efficiently.

Low-cost efficiency upgrades

Investing a small amount in efficiency upgrades can yield long-term savings.

Energy-efficient lighting

Switching to light-emitting diode (LED) bulbs is one of the easiest and most impactful upgrades. LED bulbs use 85% less energy than traditional incandescent or halogen bulbs and last significantly longer. Replacing all lights in your home with LEDs can save a substantial amount on your electricity bill.

Draught-proofing and insulation

Preventing heat loss is key to reducing heating electricity consumption. Draught-proofing around windows, doors, and even chimneys can cut heat loss by up to 20%. Simple measures like self-adhesive foam strips, letterbox covers, and chimney balloons are inexpensive and effective. Insulating your hot water cylinder with an 80mm jacket could also save around £70 a year.

Smart technology for greater control

Modern technology offers enhanced control and insights into your energy usage, empowering you to make smarter decisions.

Leveraging your smart meter and app

Your smart meter provides real-time data on your electricity consumption. Many energy suppliers, including Fuse, offer dedicated apps that connect to this data, giving you a clear overview of your usage patterns. This allows you to identify exactly when and where you're using the most electricity, helping you adjust habits or schedule appliance use during off-peak, cheaper periods. This level of transparency transforms electricity saving from a guessing game into an informed process.

Smart plugs and thermostats

• Smart plugs: These inexpensive devices plug into standard sockets and allow you to control appliances remotely, set schedules, and monitor their individual energy consumption. A smart plug with energy monitoring, like the TP-Link Tapo P110, costs around £12 and can pay for itself many times over by enabling scheduling during cheaper electricity periods and identifying phantom load.
• Smart thermostats: Designed to automate and optimise your home's heating, smart thermostats learn your habits and adjust temperatures automatically based on your presence and schedule. They can prevent unnecessary heating of empty rooms and offer remote control via a mobile app, potentially saving around £75 a year on heating bills.

Strategic investments for long-term savings

For those looking to make a more significant impact on their electricity bills and reduce reliance on the grid, strategic investments offer long-term benefits.

The potential of plug-in solar

Plug-in solar kits are an accessible way to generate your own electricity. These small systems, typically comprising a solar panel and a microinverter, plug into a standard wall socket. They offset your home's base-load usage - the constant background draw from appliances like fridges and routers.

Since 27 August 2026, Statutory Instrument (SI) 2026/848 has applied to compliant plug-in solar, allowing self-installation of up to 800W alternating current (AC) export per device. This legislation permits one such unit per property. While plug-in solar does not qualify for the Smart Export Guarantee (SEG), self-consumption is the primary saving, as you use the electricity you generate directly, reducing what you buy from the grid. Any unused generation still goes to the grid, and some suppliers may offer export tariffs outside the SEG scheme. The consumer or their supplier must notify the Distribution Network Operator (DNO) under G98 within 28 days of installation.

Considering EV charging optimisation

If you own an electric vehicle (EV), optimising your charging can lead to substantial savings. Smart EV chargers and time-of-use tariffs allow you to charge your vehicle when electricity is cheapest, often overnight. Integrating your EV charging with your home energy management system can further enhance these savings, ensuring your car charges efficiently without impacting your household budget. Learn more about EV charging at home to maximise your savings.

Electricity saving is not about sacrifice; it's about smart optimisation. By understanding your usage, making informed choices, and embracing technology, you can take control of your energy consumption and free up resources for what truly matters to you.
