What documentation is needed for Feed-In Tariffs?
Feed-In Tariffs, or FITs, were designed to pay households and businesses for generating renewable electricity, usually from solar panels. Although the scheme closed to new applicants in 2019, many UK properties still receive FIT payments under existing agreements.
If you are already on FITs, the main documents are usually your FIT application paperwork, your signed contract with the FIT licensee, and proof that your installation was commissioned while the scheme was still open. You may also need the original MCS certificate, Energy Performance Certificate details in some cases, and evidence of ownership or occupancy.
For ongoing payments, the installer or property owner may need meter readings, FIT generation meter serial numbers, and bank details for the payment account. If you move house, the FIT transfer paperwork becomes important, as the tariff can sometimes be transferred to the new owner depending on the circumstances.
What documentation is needed for solar export?
Solar export refers to the electricity your system sends back to the grid, which may be paid for under the Smart Export Guarantee, or via a separate export arrangement. Unlike FIT generation payments, export payments are generally based on measured electricity exported, not just what your system generates.
To set up export payments, you will usually need proof of a compliant installation, such as an MCS certificate, along with your distribution network operator details and the export meter information. Some suppliers may also ask for a commissioning date, inverter specification, and evidence that the export meter is capable of recording exported electricity accurately.
You will normally need to give your energy supplier your address, bank details, and a recent meter reading or smart meter reference. If your system was installed with batteries, some suppliers may ask for extra technical details to confirm how export is measured.
How the requirements differ
The key difference is that FIT documentation is tied to a legacy support scheme, while solar export documentation is usually needed to prove export eligibility and set up payment with a supplier. FITs often involve older scheme records and historic commissioning evidence, whereas export payments focus more on current installation details and meter data.
FITs may require more paperwork if you need to prove entitlement, transfer an account, or resolve issues with an existing tariff. Solar export is often simpler for new systems, but it still depends on correct certification and meter setup.
In both cases, keeping copies of certificates, meter readings, installation documents, and correspondence is sensible. This makes it easier to update your supplier, claim payments, or answer any questions about your solar system later on.
Frequently Asked Questions
Feed-In Tariffs vs solar export documentation required refers to the paperwork and proof needed to receive payments or credits for electricity exported from a solar system, depending on whether the tariff is a legacy feed-in tariff or a newer export arrangement.
Eligibility usually depends on having a qualifying solar PV system, an approved meter, a registered export arrangement, and the correct installation and commissioning documents required by your retailer, network, or scheme.
Common documents include the solar installation certificate, electrical compliance certificate, meter details, proof of ownership or occupancy, network approval, and retailer application forms for export payments or tariff enrollment.
You generally apply by submitting the required installation, meter, and account documents to your electricity retailer or scheme administrator, then waiting for approval and activation of the export payment arrangement.
Standard solar connection paperwork confirms the system is legally connected to the grid, while Feed-In Tariffs vs solar export documentation required also covers the specific records needed to qualify for export credits or payments.
It is important because without the correct documents, your retailer or utility may delay or refuse export payments, even if your solar system is producing and sending electricity to the grid.
You typically prove your system with an installation certificate, inverter and panel details, meter identification, commissioning paperwork, and any retailer or network approval letters.
You may need the meter number, meter type, export-read capability, installation date, and evidence that the meter has been configured correctly to measure exported solar electricity.
It depends on the local rules and tariff type, but many modern export arrangements require a smart or interval meter to measure export accurately, while some legacy feed-in tariffs may have different requirements.
Approval times vary by retailer, network, and scheme, but it can take from a few days to several weeks after all required documents have been submitted correctly.
If the documentation is incomplete, the application may be delayed, rejected, or placed on hold until the missing certificates, meter details, or account information are provided.
Yes, installer certificates are often required because they confirm that the solar system was installed safely, meets local standards, and is eligible to export electricity.
Yes, new systems usually need full installation and commissioning records, while existing systems may only need updated meter details, ownership evidence, or a change-of-tariff form.
A tenant can sometimes submit the paperwork if they are the account holder and have permission to use the system, but ownership, lease, or landlord approval documents may also be required.
You should contact your installer, electrician, retailer, network operator, or scheme administrator to request copies of the missing certificates, approval letters, or meter records.
It can, depending on local tax rules and whether export earnings must be reported as income, so you may need payment statements and annual summaries for tax purposes.
Proof of ownership can include a utility account in your name, property title records, a lease agreement, or a letter from the property owner authorizing the export arrangement.
Yes, but you may need to resubmit account details, meter information, and export documentation so the new retailer can continue or set up your payments.
You can check by contacting your retailer, scheme administrator, or network operator and asking whether your documents have been verified and whether export payments have been activated.
Common mistakes include missing signatures, incorrect meter numbers, outdated account details, incomplete installation certificates, and submitting documents to the wrong provider.
