Feed-in Tariffs (FIT)

Our Feed-In Tariff Participant Audit Programmes

Our participant audit programmes detect, monitor, and deter non-compliance, misreporting, and fraud for Feed-In Tariff (FIT) generators on the FIT scheme. Participants can be selected for an audit at any time. There are two types of audit programmes we currently run under the FIT scheme: targeted and statistical.

Targeted Audit Programme

Our targeted audits are intended to address known or potential areas of risk and we select targeted audits based on various factors including, for example, thematic risks (e.g., installations commissioned close to the closure of the scheme to new applicants), material risk through data analysis and from internal/external referrals.

Statistical Audit Programme 

In October 2023, a new statistical audit programme was launched for participants of the FIT scheme. This programme operates alongside the existing targeted audit programme. This programme consists of auditing randomly selected accredited installations and aims to increase our understanding of the level and types of non-compliance across the wider scheme population.

Why do we audit?

Enhancing our understanding of non-compliances on the FIT scheme 

Ofgem’s role is to protect consumers now and in the future by working to deliver a greener and fairer energy system.

Audits serve a crucial role in ensuring the integrity, accuracy, and compliance of the schemes we administer. The primary reasons for conducting audits under the FIT scheme include, amongst others:

  • ensuring participants under the scheme are meeting the eligibility requirements set out in legislation.
  • helping us to understand the level of non-compliance across the scheme’s population.
  • deterring fraud and non-compliant activity under the scheme.
  • ensuring FIT generators are adhering to the agreements in their accreditation.
  • providing assurance that the scheme is being complied with and the scheme is achieving its aims. 
  • providing valuable insights that inform our strategic planning, resource allocation, and FIT scheme improvements.
  • fostering transparency and responsible behaviour among scheme participants.

What is non-compliance?

Non-compliance is an activity which does not comply with the scheme regulations, such as failing to comply with ongoing obligations, using non-compliant equipment, or mis-stated capacity concerns.

We have rigorous systems in place for the detection and investigation of non-compliance cases.

What actions can we take?

We take non-compliance extremely seriously. If you are found to be non-compliant, depending on severity, we may: 
•    suspend payments temporarily or withhold them permanently.
•    withdraw the installation’s accreditation.
•    recover overpayments.

Where overpayments have been made, we will seek to recover these amounts by offsetting them against future payments. Where this isn’t possible, we will instead request the money owed to be repaid.


We also take fraud extremely seriously and have rigorous systems in place for the detection, prevention, and the deterring of fraud. We take firm action where there is evidence of fraud identified through an audit. 

Where there is strong evidence of wrongdoing, Ofgem reports the matter to Action Fraud and other law enforcement agencies.

If you have any suspicions of fraud within the FIT scheme, please contact us by emailing counterfraud@ofgem.gov.uk.

Preparing for an audit

To help support you in any upcoming FIT audits, we recommend you:

  • conduct regular internal self-assessments of your processes and records to identify and address potential issues proactively. 
  • collect all relevant documentation prior to an audit taking place. This could include commissioning evidence, FIT invoices, metering details, single line diagrams (SLD), procedural manuals, and any other documents relevant to the audit scope.
  • maintain an up-to-date accreditation application and ensure all changes are reflected in the application, such that when an audit takes place, the application reflects the current arrangements.
  • review your internal processes and procedures ensuring they are well-documented, accurate, and consistently adhered to. 
  • familiarise yourself with the specific scope and objectives of the audit.
  • keep yourself up to date with the latest regulations and requirements.
  • be transparent with auditors. If there are areas where questions might arise, address them openly and provide necessary context. 
  • use the audit as an opportunity for improvement. Consider how audit insights can lead to enhanced processes, reduced risks, and overall assurance that you’re receiving the right payments.

Application amendments after an audit

Following the closure of an audit, the audit findings may state that you are required to make updates and corrections to your accreditation application. Please note these changes are expected to be actioned as per the timeline outlined on closure letters. However, no application amendments should be made until the audit is closed and you have been informed.

Resources for generators

Ofgem also have several resources to help support generators. Please see the links below that provide specific guidance on essential documents that are required for audits.
