How to Appeal an Unfair Business Electricity Rate

Have you ever stared at your latest electricity invoice and thought, “This can’t be right”? Rising energy prices across the UK make that feeling common. Yet not every steep charge is fair or legal. 

When suppliers overcharge, you have the right—and a clear path—to challenge the bill and get your money back. This guide shows you each step, explains your rights, and points you to the help that wins cases.

Understanding unfair business electricity rates

What counts as unfair?

1. Overcharging – you pay more per unit than your contract says.
2. Sudden jumps – price shoots up with no notice.
3. Deemed rates – you move site or let a deal lapse, and the supplier sticks you on a pricey “default” tariff.

Ofgem rules say suppliers must treat you fairly and bill you correctly. If they don’t, you can complain.

Common red flags

• The meter reading on the bill does not match the number on the meter.
• Back-billing for more than 12 months of use.
• Bills that switch from fixed to variable without warning.

Why are electricity costs keeping climbing?

Energy markets move fast. Wholesale gas prices jump, network fees rise, and taxes add extra weight. Small and mid-sized firms feel the shock first because cash flow runs tight. If you ignore a wrong charge today, it grows into a larger hole in next quarter’s budget. Acting early keeps cash in your business and pressure on suppliers to follow the rules.

Why must you challenge unfair rates?

An unfair rate is more than an annoyance. It drains profit, limits growth, and puts jobs at risk. The energy watchdog, Ofgem, sets rules that protect you. When suppliers break those rules—by overbilling, using the wrong tariff, or raising prices without notice—you can demand a fix. Knowing the process turns a stressful bill into a winnable dispute.

How to Appeal?

If you spot an unfair charge, you can fight back and win. The following are the steps that show you how.

Step 1: Spot the exact problem

First, line up your latest bills beside your own meter readings. Check the Meter Point Administration Number (MPAN) on each invoice; it must match the label inside your meter cabinet. See if the supplier used “E” (estimated) instead of “A” (actual) readings. Estimated usage often overshoots true demand and inflates the charge.

Next, look for unexplained price jumps. If you have a variable tariff, the supplier must still inform you before each rise. For fixed deals, any increase breaches the contract. Finally, scan for back-dated costs older than 12 months. Ofgem bans that.

Step 2: Collect solid evidence

Write down the date, time, and figure shown on your meter right now. Take a clear photo as proof. Keep all bills, emails, and letters from your supplier in one folder—digital or paper. 

Add a short note each time you phone customer service: who you spoke with, what they promised, and by when. These notes build the timeline that wins disputes.

Step 3: Raise a formal complaint with your supplier

Contact customer service by phone, email, or the online portal listed on your bill. Ask for the complaints team. State the problem in one line: “You have billed me on estimated readings that overcharge my business.” 

Then back it up with your evidence: “Here is my photo of the meter on 1 June showing 14,200 kWh, but your bill claims 16,800 kWh.” Finish with the fix you want: “Please replace the estimate with my actual reading and reissue the invoice.”

Ask for a complaint reference number before you hang up. That number follows your case through every stage.

Step 4: Escalate if eight weeks pass without a fix

Suppliers have up to eight weeks to resolve a dispute. If that clock runs out—or if they send a “deadlock letter” saying they will not act—you can move the case to the Energy Ombudsman. Before you do, ring Citizens Advice on 0808 223 1133 or use their webchat for free guidance. They can review your file and flag any weak spots.

Step 5: File with the Energy Ombudsman

Most small businesses qualify if they have fewer than ten staff or under £2 million yearly turnover. File online or post the simple form with your evidence folder and the deadlock letter (or proof eight weeks have passed). The Ombudsman is neutral. They look at facts, rules, and fairness. Their ruling might order the supplier to correct the bill, refund money, or place you on the right tariff. If you accept, the supplier must act within 28 days.

Step 6: What if you still disagree?

The Ombudsman’s decision is final unless new evidence appears. If you still feel wronged, you can seek legal advice and take court action. Contact Business Debtline or a solicitor who deals in energy cases. Court costs run higher, so weigh the unpaid amount against legal fees before you leap.

Keep unfair bills from returning

Send regular readings

Submit meter data every month. A smart meter does this for you and ends estimated billing.

Review contracts early

Mark the renewal date in your diary. Shop the market three months before the end date to dodge a pricey deemed rate.

Compare business electricity deals often

Run a fresh business electricity comparison each year—even if rates look steady. Use business electricity comparisons through Utility4Business to see if a better price exists. A ten-minute check can shave thousands off your yearly spend.

Stay on top of new rules

Ofgem updates price caps and conduct codes. Reading their brief alerts keeps you ahead and ready to challenge misuse.

Extra help when cash is tight

Many small firms qualify for the Energy Bills Discount Scheme. If your usage is high and the unit cost passes a set threshold, the government refunds the extra. When arrears build up, ring the supplier early and ask for a payment plan. Suppliers must treat micro-businesses—those using less than 100,000 kWh a year or with fewer than ten staff—with extra care and offer free dispute help via the Ombudsman.

Conclusion

Unfair electricity charges drain profit, but they do not have to. Spot the error, raise the complaint, and escalate if needed. Use the free services of Citizens Advice and the Energy Ombudsman when suppliers dig in. 

Then keep control with smart meters, early contract checks, and a yearly business electricity comparison through Utility4Business. The power to cut your costs is in your hands—grab it now.
