## Summary

DESNZ has awarded a contract for the provision of transformation professional services to Ernst & Young, following a selective procurement process conducted via the Crown Commercial Services' Management Consultancy Framework Four. The project, with a value of £4,500,000, supports the Warm Homes Plan by appointing services to aid in the design, planning, and implementation of a new operating model and consumer protection frameworks. The contract period runs from 7 November 2025 to 6 November 2028. The procurement process, centred around business organisation services, was classified under CPV code 79996000 and involved a wide geographic scope, including the United Kingdom and beyond.

This contract represents significant business opportunities for large service providers with expertise in consultancy related to operational transformation and consumer protection standards, specifically aimed at enhancing public service delivery. Enterprises capable of offering strategic insights and robust implementation techniques in these domains are well-positioned to participate in similar future procurements, benefiting from frameworks such as the Crown Commercial Services. The collaboration with a major consultancy firm like Ernst & Young further exemplifies the scale and potential impact of such opportunities, inviting interest from businesses that can align with governmental objectives for public sector improvements.
