Why 72% of UK Businesses Could Be Paying Less for Electricity

Why Most Businesses Are Paying Too Much for Electricity

If you’re like most UK business owners, your electricity bill probably feels like a necessary evil, something you just pay and move on.

But here’s the catch: over 7 in 10 companies are paying more than they should, according to Ofgem’s 2024 energy market data.

This happens for three main reasons:

1. Rollover Contracts: Businesses forget to renegotiate before their fixed-term deal ends, so suppliers automatically switch them to higher “out-of-contract” rates.
2. Hidden Commissions: Many brokers include undisclosed markups in their quotes, adding 10–20% to your total costs.
3. Information Gaps: Few businesses have time to monitor fluctuating business electricity prices, especially when rates change monthly.

The result? Thousands of UK SMEs end up trapped in inflated tariffs. Ethical Switch estimates that over 72% of UK businesses could lower their energy bills simply by reviewing their contracts.

Understanding Business Electricity Rates (And Why They Fluctuate)

Your business electricity rate isn’t random; several key variables influence it. Understanding them helps you see where you can save.

The rate per kilowatt-hour (kWh), the charge for each unit of power used, is determined by:

• Your supplier’s pricing structure
• Energy market trends (wholesale costs rise and fall daily)
• Your location and meter type
• Your business’s energy usage profile

For instance, small business electricity rates often cost more per unit than those for large enterprises because of lower consumption volumes.

Meanwhile, regional grid fees and standing charges can differ between cities like London, Manchester, and Leeds, slightly altering your final rate.

Even a difference of £0.02 per kWh adds up: a medium-sized business using 100,000 kWh a year could save £2,000 annually by switching providers at the right time.

What’s Hiding in Your Electricity Contract (and How to Spot It)

Behind every electricity bill lies a quiet problem: hidden broker fees.

Many brokers earn commissions directly from suppliers, but they don’t always tell you how much. Instead, the commission is rolled into your electric business rates, inflating your price without your knowledge.

A study by The Guardian and Ofgem found that businesses often overpaid £500–£5,000 per year due to hidden broker markups.

At Ethical Switch, transparency is non-negotiable. You’ll always see your full quote breakdown so you know exactly where your money’s going. Our mission is simple: fair pricing, no surprises.

How to Find the Best Business Electricity Rates

Getting the best business electricity rates isn’t just about price; it's about timing, transparency, and choosing the right partner.

Here’s how to do it right:

1. Compare Multiple Suppliers

Don’t settle for the first offer. Prices can vary by as much as 30% between energy providers, depending on your region and usage profile.

Ethical Switch compares deals from top-rated UK suppliers, ensuring you always get competitive and fair rates.

2. Know Your Contract Type

Choose between fixed, variable, or flexible contracts. Fixed plans lock in prices for 1–3 years, shielding you from market spikes, ideal when you want budget stability.

3. Watch for Renewal Dates

Missing your contract renewal window can automatically push you into expensive “deemed” rates. Set a reminder or let Ethical Switch track it for you.

4. Ask for Commission Transparency

Always request a breakdown of fees. Knowing your broker’s margin can save you from inflated business electricity prices down the line.

By following these steps, most UK businesses can reduce electricity spending by 20–35%, freeing up valuable cash flow for growth.

Why Small Businesses Are Always Hit The Hardest

Small businesses often bear the brunt of high electric business rates.

Unlike large corporations, SMEs rarely have dedicated energy managers or in-house procurement teams, which makes them more vulnerable to overpaying.

According to FSB data, 78% of small UK businesses haven’t switched suppliers in over two years. That lack of action means missed opportunities on average; SMEs could save £900 to £1,400 a year by switching or renegotiating contracts.

For a café in Birmingham or a salon in Leeds, that’s enough to cover a month’s rent or upgrade key equipment. With Ethical Switch, comparing small business electricity rates is effortless, fair, and completely free.

Electricity Rates UK Business: How They Compare

Here’s a look at average business electricity rates per kWh in the UK for 2025 (based on data from Ofgem and major energy providers):

Energy inaction is expensive.

Every month you delay reviewing your business electricity rate, you might be losing hundreds.

For example, if your current rate is just £0.03 above market average, and your business uses 100,000 kWh annually, you’re losing £3,000 a year that could easily stay in your pocket with the right switch.

In the long run, businesses that ignore their electricity contracts end up paying 25–40% more than proactive companies that compare regularly.

Ethical Switch’s data shows that even after one switch, 82% of businesses never return to overpaying again.
