The audit process allows Heat Trust to monitor a Registered Participant’s compliance with the Heat Trust Scheme, and assess the impact and effectiveness of the Scheme Rules and Scheme Bye-Laws.

Registered Sites will be audited once every five years, unless risk factors for consumer detriment are identified, in which case audits will be conducted more frequently.

Audits are conducted independent of the Heat Trust Scheme through independent auditors. 

The audits assess both the information and the level of service provided by the Supplier, checking against key standards of the Heat Trust Scheme. A high-level overview of the evidence sought in our audits can be found in Appendix 1 of the Audit Guidelines for Registered Participants, see below. These Guidelines should be read in conjunction with the Scheme Rules and Scheme Bye-Laws.

FAQs on audits

All audits are undertaken by independent Auditors appointed under contract by Heat Customer Protection Ltd.
All heat networks registered with the Heat Trust Scheme will be audited at least once every five years. An audit can be desk-based or site-based.
An audit can take place earlier if the heat network receives a significant number of complaints. The Scheme Administrator can also request an audit if they believe an audit would be beneficial.
Trials of the audit process were undertaken to allow independent auditors to provide feedback on the process before finalising the audit procedure. The first formal audits have been undertaken and several more are in preparation.
If a heat network fails an audit and the failure is severe, a non-compliance panel will be convened to decide what action should be taken, including if the heat network can remain part of the Heat Trust Scheme.
