## Summary

The Department for Energy Security and Net Zero (DESNZ) has concluded a procurement process to appoint a hydrogen technical adviser for its HICC Directorate, with the contract awarded to Guidehouse Europe Limited. This award notice stems from a selective procurement method under the DESNZ ENZPS Framework, indicating that the procurement process focused on pre-qualified suppliers within an established framework agreement. The contract, valued at £7,500,000 GBP, spans from 13th October 2025 to 8th October 2028, covering energy and related services within London, United Kingdom. Though the tender stage is complete, this award signifies a pivotal step in enhancing DESNZ’s expertise in hydrogen projects.

This procurement offers substantial opportunities for business growth within the energy services sector, particularly for companies specialising in hydrogen technologies and consultancy services. Of note, the suitability criteria deem SMEs eligible, highlighting that well-established small to medium enterprises with robust technical advisory capabilities could find similar contracts within framework agreements advantageous. For businesses focussing on innovation and technical expertise in renewable energy, this represents a lucrative prospect to engage closely with government-led initiatives aimed at advancing the UK’s energy security and net-zero commitments. As the awarded contract's location is London, enterprises based in the UK or with operations there may find logistical advantages in meeting the contracting authority’s requirements efficiently.
