How to Make Sure You Don’t Get Ripped Off on Business Energy
This practical guide is written for UK businesses who want to avoid nasty surprises on their gas and electricity bills. It covers the key checks at each stage of the journey – before you sign, on the day your contract starts, when meters are swapped, and every time a bill lands.
This page is general information only, not financial or legal advice. Always speak to your supplier, broker, accountant or legal adviser if you’re unsure about anything on your contract or bill.
1. Before You Sign Any Business Energy Contract
Most bill problems start before the contract is even agreed. If you get this stage right, you massively lower the risk of being overcharged later.
1.1 Confirm exactly what you’re agreeing to
- Get the offer in writing – not just over the phone.
- Check the unit rate (p/kWh) and standing charge (p/day) are clearly stated for each meter and fuel.
- Check the contract length – 1, 2, 3 years or more, and whether there are exit or early termination fees.
- Check if the contract is fully fixed or if any element is variable (e.g. pass-through charges).
- Confirm how renewals work – do you roll onto out-of-contract rates, a default tariff, or another fixed deal?
1.2 Understand the role of any broker or consultant
- Ask if you are dealing with a supplier directly or through a broker/consultant.
- Ask how the broker is paid – for example, are they adding a commission into the unit rate, or paid separately by the supplier?
- Ask if they are tied to specific suppliers or genuinely compare the wider market.
- Don’t feel rushed – pressure to “sign today or lose everything” is usually a red flag.
1.3 Pre-sign checklist
Before you sign, you should be able to answer “yes” to all of these:
- I know my unit rate (p/kWh) and standing charge (p/day) for each meter.
- I know the exact contract start date and end date.
- I understand if the deal is fully fixed, partially fixed or variable.
- I know what happens at the end of the contract and how to avoid being rolled over.
- I know who to contact (supplier or broker) if something looks wrong later.
2. On the Day Your Contract Starts: Meter Readings Are Critical
The easiest way for a business to be overcharged is for the opening reading to be wrong. If your starting point is wrong, every bill afterwards can be out.
2.1 Take and store your own meter readings
- On the day your new contract starts, take clear meter readings for every meter (electricity MPAN and gas MPRN).
- Take photos with timestamps (phone photos are fine) showing the meter display and, if possible, the meter serial number.
- Send these reads to your new supplier through their portal, app or by email/phone and keep a record of how and when you sent them.
2.2 Check your first bill against your own reads
- When your first bill arrives, check that the opening read on the bill matches the reading you supplied.
- Ensure the bill shows “A” (actual) or “C” (customer) reads, not just estimates, for the start of the contract where possible.
- Check the unit rates on the bill match the contract you agreed (p/kWh and standing charge).
2.3 Opening-bill checklist
- The MPAN/MPRN on the bill is definitely my site.
- The opening read matches my photo and the date is correct.
- The unit rate and standing charge match my contract.
- The billing period is from my start date, not before.
3. When a Meter Is Swapped or Changed
Meter exchanges (for smart meters, half-hourly meters or faulty meters) are a common point where billing can go wrong. You need a clean handover between the old and new meter.
3.1 What to do before and after a meter swap
- Before the engineer leaves, note or photograph the final reading on the old meter.
- Take a photo of the new meter’s serial number and initial reading.
- Ask the engineer or supplier for a job reference or exchange report and keep it on file.
- After the swap, check that your next bills show the old meter closing read and the new meter opening read correctly.
3.2 Meter-change checklist
- I have photos of the old meter’s final reading and serial number.
- I have photos of the new meter’s serial number and opening reading.
- I have a record of the date and, if possible, the engineer’s job reference.
- I’ve checked subsequent bills to make sure the swap has been handled correctly.
4. Regular Billing Checks to Keep Costs Under Control
Even if your contract and opening reads are correct, things can still drift. A simple monthly or quarterly check can stop small issues turning into big problems.
4.1 Compare billed usage with your own reads
- Take and store your own meter reads at least once a month (or more often if usage is high).
- Check if your bills are based on actual reads or estimates. Too many estimates can lead to unexpected catch-up bills.
- If the supplier’s billed reads look wrong, submit your own customer reads and ask for the bill to be corrected.
4.2 Check every bill for obvious errors
- Unit rate and standing charge match your contract.
- Billing period dates are correct and not overlapping.
- Any discounts or agreed terms (e.g. bespoke rates) appear as expected.
- Direct Debit amounts match what you’d expect for the period and usage – not wildly higher or lower.
4.3 Watch for out-of-contract or deemed rates
- Out-of-contract/deemed rates are usually significantly higher than agreed contract rates.
- Make a note of your contract end date and start looking at renewal options well before your notice window.
- If a bill suddenly jumps in price, check if the tariff type has changed on the bill.
5. Questions to Ask Your Broker or Supplier
Good brokers and suppliers should be happy to answer clear and simple questions. If they avoid or dodge these, treat it as a warning sign.
5.1 About your current or proposed contract
- Is this the best deal you can see for my type of business and usage?
- How are you paid for arranging this contract?
- Is anything in this contract variable or pass-through?
- What are the early exit fees or conditions?
- What happens at the end of this contract if I do nothing?
5.2 About problems or disputes
- What’s the process if I think a bill is wrong?
- How quickly do you normally resolve billing issues?
- Who do I contact if I feel I’ve been mis-sold or overcharged?
6. If You Think You’ve Been Overcharged
If something doesn’t look right – for example a huge jump in cost, strange estimates, or a bill that doesn’t match your usage – act quickly and keep everything in writing.
6.1 Gather your evidence
- Copies of your contract or offer letters/emails.
- Photos of meter readings and exchange reports (if meters were swapped).
- All recent bills, especially the first bill and the one that looks wrong.
- Any emails or notes of calls with brokers or suppliers.
6.2 Raise the issue promptly
- Contact your supplier first, explain clearly what looks wrong and provide your evidence.
- Keep everything in written form where possible (email/portal messages) so you have a record.
- If a broker arranged the contract, you may also want to raise it with them directly.
6.3 Escalation
If you’re not getting anywhere, ask about their formal complaints process and make a complaint in line with it. Keep copies of everything you send and receive.
7. Quick Checklist: How to Avoid Getting Ripped Off
- Always get your business energy offer in writing.
- Know your unit rate, standing charge, contract length and what happens at renewal.
- Take and store meter photos on the day your contract starts.
- Do the same when a meter is changed or swapped.
- Check the first bill very carefully against your own readings and contract.
- Avoid staying on out-of-contract/deemed rates any longer than necessary.
- Query anything that doesn’t make sense and keep everything in writing.
- Set reminders for your contract end date so you’re never caught out.

9. Quick FAQs: Avoiding Overcharging on Business Energy
How can I avoid getting ripped off on my business energy contract?
Always get your offer in writing, check the unit rate, standing charge, contract length and renewal terms, and make sure you understand whether any charges are variable or pass-through. Take your own meter reads on the start date and keep everything in writing with your supplier or broker.
What should I check on my first business energy bill?
Check that the opening read matches your own photo, the MPAN/MPRN is definitely your site, the unit rates and standing charges match your contract, and the billing period starts from your agreed contract start date. If anything looks wrong, raise it with your supplier promptly.
How often should I read my business energy meters?
For most SMEs, taking meter readings at least once a month is a good starting point. Higher-usage or multi-site businesses may benefit from more frequent reads to avoid large estimated bills and catch issues early.
What should I do if I think my business has been overcharged?
Gather your contract, bills, meter photos and any call notes, then raise the issue with your supplier in writing. Explain clearly what looks wrong and provide your evidence. If the contract was arranged by a broker, you may also want to raise it with them, and follow the formal complaints process if needed.
