5 Proven Ways to Reduce Electricity Waste in 2026

This checklist was developed by Rochel Lewis, Marketing and Communications Manager at Chauvin Arnoux UK, to help you take simple, practical steps to become more energy efficient.

Following the COVID-19 pandemic, electricity prices rose sharply, contributing to an energy affordability crisis across the UK. As a result, both business owners and homeowners have been actively seeking ways to reduce their electricity costs.

Recent reports indicate that Ofgem has set the UK energy price cap so that average combined gas and electricity bills are expected to fall to around £1,641 per year for the period 1 April to 30 June 2026. This represents a reduction of roughly 7% compared to the previous cap, driven mainly by lower wholesale energy costs and changes to policy levies. However, analysts warn that prices could rise again later in the year if global energy costs increase.

Despite the energy price cap, electricity bills remain a significant concern. Household energy prices in the UK are still higher than pre-covid levels, and industrial electricity prices are among the highest in Europe, according to recent House of Commons committee reports. These high costs continue to put pressure on households and businesses across the UK.

To help address rising electricity bills, this article outlines 5 proven ways to reduce energy consumption at home, in commercial settings, and across industrial operations. These approaches not only help cut costs but also support environmental sustainability by reducing unnecessary energy waste.

1. Run Regular Maintenance Checks

Businesses and homeowners alike can benefit financially and environmentally by ensuring electrical systems are in good working order.

Regular maintenance checks aren’t just a safety requirement. Devices such as air conditioning units, heating systems, and other electrical equipment can directly affect energy consumption. Neglect or failure to perform maintenance checks can cause energy efficiency levels on these devices to decline over time, directly affecting your electricity bills.

Research suggests that well-maintained equipment performs more reliably and consumes up to 15-20% less electricity (Gradwell Group, GOV.UK 2025).

Ensuring your filters, vents, and cooling fans are cleaned regularly to prevent overheating, replacing inefficient components with more energy-efficient alternatives, or opting for more advanced inspections under UK guidelines such as PAT testing will help achieve optimal machine performance and energy savings.

2. Reduce Standby Power Waste

Unmonitored electronic devices can inflate household electricity bills even when not in use. In late 2025, average UK households could have wasted around £80 a year by leaving appliances on standby rather than fully turning them off (Go.Compare Energy).

Data from Measurable Energy suggests that up to 20% of total electricity use in offices could be from devices that are not in active use or from after-hours consumption – generally caused by standby/idle loads.

While a single standby device might draw only a few watts, with multiple devices like computers, printers, and HVAC systems, even with the energy price cap, standby consumption can add up quickly.

3. Invest in Energy-Efficient Upgrades

Electrical devices are built to perform, but older systems can quietly drain energy without you even recognising the pattern. Investing in newer, energy-efficient appliances or equipment (wherever applicable) could be the way to go, as this will help reduce unnecessary power use straight away. So, whether it’s a small change, such as switching to LED light bulbs or motion-sensor lighting, or a relatively more expensive alternative, such as industrial equipment – moving towards energy-efficient upgrade for offices or homes can translate into lower energy bills.

4. Maximise Efficiency by Enabling Low-Power Mode

Electrical equipment often runs continuously. Businesses and household consumers can optimise usage and downtime by scheduling equipment use. Be it in industrial or residential settings, using programmable timers or smart plugs to power down instruments when not in use can help maximise energy efficiency efforts.

Pairing these practices with staff awareness can ensure instruments consume full power only when needed, thereby improving efficiency and reducing costs.

5. Monitor Energy Consumption

Pro tip – sometimes it’s a lot easier to assess energy usage patterns early on to curb spending and electricity waste. And when it comes to saving your operational budget, energy consumption monitoring helps ensure every pound is spent well.

Businesses and electrical specialists often employ energy monitoring systems on-site to track real-time consumption, log data to identify inefficiencies, optimise performance, and reduce energy costs.

Don’t just take our word for it! See how data loggers measure voltage, current, power factor, harmonics, and more, and provide a detailed breakdown of consumption so that you know how and where your money is really going. Here’s a quick YouTube video on the top features and benefits of using a power and energy logger.

Considering opting for Solar PV?

Installing a commercial solar PV rooftop array could be a practical move, but one that’s quite expensive.

Generating your own electricity on-site can reduce reliance on the grid, lead to lower monthly energy bills, and improve your sustainability efforts. But considering costs vs potential savings is crucial in this scenario, since the initial investment may depend on several factors that can affect both your upfront spending and long-term savings plan.

And there you have it — these are 5 proven ways to reduce electricity waste in 2026! Whether you’re running a small or medium-sized business looking to cut operational costs, an electrical contractor seeking smarter ways to help your clients save more, or a homeowner wanting to lower your energy bills, this checklist is designed to help you take practical steps toward becoming more energy-efficient.
