Out-of-Contract and Variable Rates
What happens when your E.ON Next fixed contract ends — and what to do about it.
Am I in contract?
Check your most recent E.ON Next bill or correspondence for the contract end date. You can also log into your online account at eonnext.com/business/login. If you are unsure, contact us with your MPAN or MPRN and we can check.
What happens when my fixed contract ends?
If you do not renew or switch, E.ON Next will normally move you onto their out-of-contract variable rates. Your supply continues — it is not cut off. However, variable rates are typically higher than fixed contract rates.
How do I know if I am on variable / deemed rates?
Your bill will show the tariff name. If it says 'variable', 'deemed', 'out of contract' or similar, you are not on a fixed rate. Contact us and we can check your current tariff and compare it against available fixed options.
What should I do if I am out of contract?
Act promptly. The longer you remain on variable rates, the more you are likely to pay. Contact us for a comparison — we can often arrange a new fixed contract within a few days.
"You are out of contract" — cold calls
Businesses regularly receive unsolicited calls claiming their contract has expired. Always verify your contract status independently — check your bill, log into your account, or contact us — before agreeing to anything over the phone.
Last checked: 8 August 2026. E.ON Next out-of-contract rates are not published here as they change regularly.
Received a suspicious call about your E.ON Next meter or account?
Businesses sometimes receive unexpected calls claiming that a meter needs to be changed, that there is a fault on the account, or that bank details are required. Before acting on any unexpected call:
- Do not provide bank details or payment over the phone unless you initiated the call.
- Verify the caller independently — hang up and call E.ON Next directly on 0808 501 5699.
- E.ON Next will not ask for payment by unusual methods (gift cards, bank transfer to a new account).
- If you are unsure, contact us and we can help you verify whether the call is genuine.
Market-wide Half-Hourly Settlement (MHHS) — what E.ON Next business customers need to know
MHHS stands for Market-wide Half-Hourly Settlement. It is an industry-wide programme that changes how electricity consumption is measured and settled across the market. Under MHHS, settlement data moves to a half-hourly basis, meaning consumption is recorded in 30-minute intervals rather than estimated or averaged over longer periods.
Business customers may hear about MHHS in the context of meter upgrades, changes to how their usage data is recorded, or updates to how their bills are calculated. E.ON Next, like all licensed suppliers, is required to comply with the MHHS programme.
If E.ON Next needs you to take action, they will contact you directly. Most customers do not need to do anything unless they receive specific correspondence from E.ON Next or their meter operator. If you have received a letter or email about MHHS, a meter change or half-hourly settlement and are unsure what it means for your contract or costs, contact us for independent guidance.

My E.ON Next bill has suddenly increased
A sudden increase can result from estimated bills being corrected, a tariff change, or a move onto variable rates. We check each in turn.
Read MoreMy bill is estimated
Estimated bills can accumulate over months and lead to a large catch-up charge. We explain how to resolve this and what to check.
Read MoreMy meter readings do not match the bill
This can indicate a registration error, a wrong meter, or a billing system issue. We explain what to check first.
Read MoreMy smart meter is not sending readings
Smart meter communication failures are common. We explain the likely causes and what you can do while the issue is being resolved.
Read MoreMy supplier needs meter photographs
Suppliers ask for meter photographs to verify the serial number and current reading. We explain exactly what is normally required.
Read MoreMy supplier wants readings one hour apart
Two readings taken an hour apart help identify whether a meter is running faster than expected. We explain the process.
Read MoreI think my meter is running too fast
A meter running faster than expected is a serious issue. We explain what a load test is and how to request one.
Read MoreWhat is a check meter?
A check meter is a temporary meter installed alongside the existing one to verify accuracy. We explain when they are used.
Read MoreWhat is a load test?
A load test measures actual electricity consumption against what the meter records. We explain the process and what happens next.
Read MoreMy switch has been objected to
Switch objections can be raised for several reasons. We explain the most common causes and how to resolve them.
Read MoreMy Change of Tenancy is delayed
CoT delays are common and can have financial consequences. We explain the usual causes and what you can do.
Read MoreI have received a large catch-up bill
A catch-up bill can arrive after months of estimated billing. We explain the 12-month backbilling rule and how it may apply.
Read MoreI think I am being billed for the wrong meter
Incorrect meter registration does happen. We explain how to check the MPAN and registered supplier.
Read MoreE.ON Next cannot find my meter
If a supplier cannot locate your meter, the MPAN or MPRN may need to be verified. We explain the process.
Read MoreI have several MPANs at the same premises
Multiple MPANs at one site can mean different contracts, tariffs and end dates. Each one should be checked individually.
Read MoreWhy am I paying a standing charge when I use no energy?
The standing charge covers fixed network costs and applies regardless of consumption. We explain what it covers and whether it can be reduced.
Read MoreHow We Investigate an E.ON Next Bill
There is little point arguing about prices until we first know whether the supplier is billing the correct usage.
Check the site and account details.
Check the MPAN or MPRN.
Compare the meter serial number.
Ask for a current meter reading and photograph.
Check whether readings are actual, customer supplied, smart or estimated.
Compare usage with earlier bills where available.
Look for catch-up billing.
Check unit rates.
Check standing charges.
Check contract and tariff status.
Review VAT and CCL where relevant.
Explain what we have found in plain English.
Our starting point
There is little point arguing about prices until we first know whether the supplier is billing the correct usage. That is always where we begin.
Questions Businesses Ask Us About E.ON Next
Real questions, answered plainly. Where an answer depends on circumstances, we say so.
From Our Experience
E.ON Next has been a significant supplier in the SME market for many years, and one of the things customers often recognised was the relatively low standing charge on many historic electricity quotations. That made the supplier particularly attractive for some lower usage sites.
From July 2026, the way E.ON Next structures SME electricity standing charges changed, so simply looking for the lowest daily charge is no longer enough.
For a low usage meter, the standing charge can have a major effect on the annual cost. For a high usage meter, even a relatively small difference in the unit rate can matter much more. That is why we normally compare the estimated annual spend rather than declaring one tariff better simply because one figure looks cheaper.
We also regularly see customers with several E.ON Next meters where one contract has been renewed but another supply has been overlooked. For multi-site customers, every MPAN and MPRN should be checked individually.

One Thing That Catches Businesses Out
A low standing charge does not automatically mean a cheap contract.
Illustrative example — not current E.ON Next prices
Tariff A
Tariff B
| Annual usage | Tariff A cost | Tariff B cost |
|---|---|---|
| 5,000 kWh | £1,473 | £1,319 ✓ |
| 15,000 kWh | £4,273 | £3,519 |
| 30,000 kWh | £8,473 ✓ | £6,819 |
Figures are illustrative only and do not represent current E.ON Next prices. VAT not included.
The fairest comparison is normally the estimated annual cost based on realistic usage.
That is why we always ask for your annual consumption before comparing tariffs.
