## Summary

The Department for Energy Security & Net Zero, located in London, has completed a procurement process under the Green Deal Framework Regulations for the Green Deal Ombudsman and Investigation Services. This procurement, requiring direct award due to the supplier’s unique certification by OFGEM, involves providing investigation services for complaints related to the Framework Regulations. The contract was awarded to ENERGY OMBUDSMAN LIMITED, a certified supplier based in Warrington, effective from December 17, 2025, through December 7, 2029. The process falls within the services category and involves a direct procurement method aimed at resolving customer complaints efficiently.

This procurement offers business growth opportunities especially for certified specialist organisations in the energy services sector capable of undertaking ombudsman roles. Small to medium enterprises (SMEs) with expertise in regulatory compliance, customer grievance redress, and professional service delivery could find substantial opportunities in contracts requiring specialised investigation and complaint resolution abilities. The unique procurement requisition primarily revolves around technical capacity and certification, positioning ENERGY OMBUDSMAN LIMITED as the suitable party, highlighting niches for businesses pursuing similar operational certifications and roles.

## Notice

The procurement is for an ongoing requirement under the Green Deal Framework Regulations (Disclosure, Acknowledgement, Redress etc) Regulations 2012 (the 'Framework Regulations') place a duty on the Secretary of State to have a GD Ombudsman Scheme in operation. The GD Ombudsman Service will investigate and consider cases relating to complaints relating to alleged breaches of the Framework Regulations. It is one of the first routes of complaint resolution for customers where their complaint has not been satisfactorily resolved by the initial parties involved and is an important step in DESNZ's ability to apply sanctions
