Why we audit
We have a responsibility to protect public funds by making sure participants comply with the scheme rules. This is why we carry out audits.
Who we audit
Anyone can be selected for an audit at any time. We select heating systems based on a number of selection criteria, including random sampling.
What does an audit involve?
There are two different types and your heating system could be selected for either:
- A desk audit which involves us asking you to supply certain documents and records.
- A site audit. We’ll inspect the heating system and also ask to see certain documents and records at the same time. The site visit may be carried out by external auditors.
We ask for your cooperation if you receive an audit request. If you don’t respond to the request, we may have to suspend your payments while we try to make arrangements for auditors to visit.
You can read more about our enforcement powers in Guidance Volume 2, Chapters 13 and 14.
Documents you need to keep
Please read the Easy Guide to Compliance for details of key documents we may ask for, which include:
- A copy of the Microgeneration Certification Scheme (MCS)open key term pop-up certificate, or certificate from equivalent scheme (if applicable)
- Purchase receipts for the heating system
- Fuel receipts or invoices, including evidence of sustainability requirements (if applicable)
- Heat meter calibration certificates, if applicable
- Clear fuel records which show the types and volume of fuel used
- Installation commissioning certificate
- Installation emissions certificate
- A record of heat meter readings submitted to Ofgem.
You might also be asked for further evidence.
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 using heat for non-eligible purposes.
We have rigorous systems in place for the prevention, detection and investigation of non-compliance cases.
