Rule: If you move out you must provide a final meter reading and either close the account or transfer the supply to the new occupier. Required proof: forwarding address for final bill, final meter reading, move date and proof of new address (optional). Applicable law: Consumer Rights Act 2015 for final bill accuracy.
Rule: If your tariff includes a contractual right to leave because of a price increase you can cancel and switch without exit fees where the tariff terms allow. Required proof: the price change notification from E.ON or page references to the tariff change in your paperwork. Applicable law: Unfair contract term considerations under the Consumer Rights Act 2015 and CMA guidance on auto-renewals.
Rule: The executor or household member should contact E.ON to close the account. Required proof: death certificate or executor documentation and account details. Applicable law: Consumer Rights Act 2015 for dealing with consumer contracts on death.
Rule: E.ON accepts withdrawal under the 14-day cooling-off period for distance contracts. Research notes an additional grace period if withdrawing during the cooling-off window while already on supply, during which you may choose another tariff or supplier. Required proof: the cancellation confirmation, cooling-off reference and any meter readings if energy has been supplied. Applicable law: Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013.
Rule: For fixed-term tariffs ending after 12 or 24 months, you may leave on the end date without exit fees. Required proof: account statement showing tariff end date. Applicable law: Contract terms; Consumer Rights Act 2015 for fairness of post-term charges.
Rule: You have 14 days from the day after the contract is entered into to withdraw from online or off-premises contracts. If you asked for supply to start inside that 14-day period and received energy, E.ON can charge for energy used. If you withdraw during the cooling-off period while already on supply, E.ON provides a grace period to select another tariff or supplier; if you take no action you will be put on the standard variable tariff. Required proof: your cancellation notice and any meter readings. Applicable law: Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013.
Retention offers reported in public research: none specifically reported for E.ON in the supplied research data. To request a retention offer, contact E.ON through your online account or by phone, provide your current tariff name and renewal date, and ask for a discount or a fixed-rate offer. If you are within the 14-day cooling-off period, request withdrawal instead of a retention offer.
Compute savings between two E.ON plans using published prices.
Example 1 - Next Flex versus Next Pledge:
Next Flex monthly estimate: £145.42. Annual cost: £145.42 x 12 = £1,745.04 per year.
Next Pledge annual cost: £1,532. Annual difference: £1,745.04 - £1,532 = £213.04 saved per year by moving from Next Flex to Next Pledge.
Example 2 - Next Fixed 12m versus Next Pledge:
Next Fixed 12m annual cost: £1,602. Next Pledge annual cost: £1,532. Annual difference: £1,602 - £1,532 = £70 saved per year by moving from Next Fixed 12m to Next Pledge.
Competitor cheapest alternative price: not publicly disclosed in the supplied research. Use the calculated E.ON plan comparisons above when deciding whether to cancel or switch.
The Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013 give a 14-day cooling-off right for most online and off-premises contracts. The Consumer Rights Act 2015 requires services to be carried out with reasonable care and skill and prevents unfair contract terms. The CMA enforces rules on hard-to-cancel subscriptions and unclear auto-renewal terms.
First complain to E.ON via your account, phone or post. If your complaint is not resolved after eight weeks, or you receive a final resolution offer (deadlock letter), you can take the case to the Energy Ombudsman for free, impartial dispute resolution. For general guidance on cancelling services and consumer rights consult Citizens Advice - Cancelling a service.
Provide an up-to-date final meter reading so E.ON can calculate whether you are due a refund or owe a final balance. For refund requests you must normally give a meter reading within 14 days of the request unless you have a smart meter that provides remote readings.
If there is a credit on your account, E.ON will decide if you are due a refund after a meter reading is provided. For a final bill refund you must also provide a forwarding address. E.ON will not try to recover charges for energy older than 12 months unless they have already attempted recovery or the customer has behaved obstructively or unreasonably.
If you left E.ON Next and withdrew from a new supplier during a cooling-off period and want to return, contact E.ON and they will place you back on your previous tariff where allowed by their procedures.
