Can you lose export tariff income when you switch?
In most cases, you should not lose your solar export payments just because you change electricity retailer. If you are on an export tariff, the payment is usually tied to your export meter and the terms of the scheme, not to a fixed retailer forever.
That said, the new supplier must be able to administer your export arrangement properly. If the switch is not handled correctly, payments can be delayed, paused, or occasionally set up again from scratch.
How export tariffs usually work in the UK
Many UK homes with solar panels are paid for electricity they export to the grid through schemes such as the Smart Export Guarantee. Under these arrangements, suppliers offering export tariffs can set their own rates and conditions, within the rules of the scheme.
Some households have a separate export agreement, while others have export and import with the same company. If your export tariff is linked to a specific supplier, changing retailer may mean you need to reapply or move onto a new export deal.
What can go wrong during a switch?
The biggest risk is not permanent loss of income, but a gap in payments. If meter readings are not transferred properly, or the new supplier does not have your export details, your export data may not be recognised immediately.
There can also be admin delays while the new retailer verifies your meter, MPAN details, and installation information. During this time, export payments may be put on hold until everything is confirmed.
How to avoid missing payments
Before switching, check whether your current export tariff is separate from your import tariff. Ask both the old and new supplier what will happen to your export payments, and whether you need to sign a fresh export agreement.
Keep copies of your latest bills, export readings, and any solar installation documents. It is also sensible to take meter readings on the day you switch, so there is a clear record of what was exported before and after the change.
When to be extra careful
If you are on a higher-paying legacy export tariff, be cautious before moving. Some older arrangements are more valuable than standard export rates, and switching retailer could mean you cannot keep that exact deal.
You should also check whether your new retailer even offers an export tariff. If they do not, you may need to find a separate company for export payments, or you could end up exporting without being paid properly.
The bottom line
For most UK households, changing electricity retailers does not automatically mean losing solar export income. However, it can cause delays or a change in tariff if the new supplier cannot continue the same arrangement.
Always check the terms before you switch. A quick phone call or email to both suppliers can help make sure your export payments continue without interruption.
Frequently Asked Questions
Extra solar power export tariff income lost changing electricity retailer refers to money you may stop receiving, or receive at a lower rate, when you switch electricity retailers and your solar feed-in tariff terms change, end, or are replaced by a new offer.
Eligibility depends on the retailer, the tariff type, the contract terms, your location, and whether your previous export rate was guaranteed. Some plans offer no compensation, while others may provide a credits, retention offer, or transition payment.
It can reduce the amount you earn for each kilowatt-hour exported to the grid if your new retailer offers a lower feed-in tariff, removes a bonus, or changes conditions that previously increased your export income.
It usually occurs because the new retailer has a different pricing structure, the old tariff was a limited-time incentive, or the switch caused you to lose access to a grandfathered export rate or promotional credit.
Compare your old export rate and any bonuses with the new export rate, then multiply the difference by your expected exported solar energy over the same period to estimate the income lost.
You may need past electricity bills, solar export statements, your old and new plan details, contract terms, meter data, and any written communication from both retailers about tariff changes.
You may reduce the risk by checking the feed-in tariff, demand charges, usage rates, exit fees, and any time-limited solar incentives before switching. A cheaper usage rate can still result in less total value if export income drops.
Yes, it can include the loss of bonus credits, sign-up incentives, guaranteed feed-in periods, or promotional export payments if those benefits disappear when you move to a new retailer.
It lasts for as long as the lower export rate, reduced bonus, or changed tariff applies. For some customers it is permanent under the new plan, while for others it may only last until a promotional period ends.
Sometimes, but only if the retailer made an error, failed to disclose terms properly, or breached a contract. If the loss is simply due to switching to a different tariff, a refund is less likely.
Check the solar feed-in tariff, rate changes after any introductory period, contract length, exit fees, network charges, billing method, and whether your existing export arrangement will transfer or be reset.
Yes, it can be different. Switching plans within the same retailer may preserve some solar benefits, while changing to a different retailer can reset or remove export incentives and other tariff protections.
Yes. If the new retailer requires a meter change, a gross-to-net solar setup change, or a different billing arrangement, your export payments can be delayed, altered, or reduced.
Contact the retailer with your account details, bills, and evidence of the expected tariff. Ask for a review, correction, or explanation, and escalate to the energy ombudsman or regulator if the issue is not resolved.
In some regions, solar export income may be treated differently for tax purposes. Losing export income usually does not create a tax deduction automatically, so you should check local tax rules or a qualified adviser.
Some government programs may support solar customers through rebates, bill relief, or consumer protections, but they usually do not directly replace lost retailer export income unless a specific scheme applies.
Normal market changes affect everyone on variable tariffs, while this issue specifically concerns income lost because a retailer switch changed your export tariff, removed a bonus, or ended a special offer.
Compare your contract, bill, and meter data. If the export rate was changed by your retailer, it is usually a retailer issue. If charges or credits changed because of local network rules or metering, it may be a network-related issue.
Ask what your current export rate is, whether any solar bonuses ended, whether your old tariff had grandfathering, whether a meter or plan change affected exports, and whether any compensation or alternative offer is available.
You can contact the retailer’s billing team, your state or regional energy ombudsman, a consumer advocacy service, or a qualified energy adviser who can review the bill and explain the tariff changes.
