The Defence Infrastructure Organisation has opened early market engagement for client-side support for net zero, signalling a need for dedicated expertise to keep its net zero carbon work on track. The organisation is looking for a specialist subject matter expert to continue net zero carbon surveys and planning, underlining how climate governance is becoming a standing capability rather than a one-off task.
On 11th September 2026, the Defence Infrastructure Organisation published a short Prior Information Notice stating that “support is needed for the continuation of Net Zero Carbon surveys and planning through the provision of a specialist Subject Matter Expert.”
Although brief, the wording points to an embedded advisory role focused on how the organisation measures and plans its route to net zero. The emphasis is on surveys and planning rather than on delivering physical works, suggesting a need to coordinate data, methodologies and internal decision-making.
The notice does not yet set out scope, contract value, locations or specific outputs. Nor does it say whether the subject matter expert will come via a consultancy firm, a framework call-off or some other route. But it is clear that the Defence Infrastructure Organisation expects ongoing, structured support rather than ad hoc advice.
The PIN highlights three linked elements:
For suppliers in the sustainability and ESG consultancy market, it is an early signal that defence infrastructure is building internal capacity around net zero governance and may bring a formal tender to market later.
The Defence Infrastructure Organisation’s search for client-side net zero support sits within a wider pattern of public buyers procuring climate governance and advisory capacity alongside delivery contracts.
In March 2026, Leeds and York Partnership NHS Foundation Trust, trading as North of England NHS Commercial Procurement Collaborative ("NOE CPC"), issued a contract notice for a Decarbonisation Support Framework. That framework is designed to help NHS and other public sector organisations develop and deliver Green Plans, covering estates decarbonisation, energy infrastructure schemes, strategic planning, project management, funding application support and full lifecycle services.
Also in March 2026, Countess of Chester Hospital Commercial Procurement Services signalled plans for a Framework for Energy Infrastructure Improvement. The aim there is to appoint a partner to manage a framework for low carbon energy infrastructure improvements and resilience services for the wider public sector, blending technical know‑how with long-term programme stewardship.
Regulators are taking a similar path. In April 2026, the Commission for Regulation of Utilities launched a tender for Energy Expert Support for Decarbonisation, seeking consultancy input on economic and technical aspects of decarbonisation and, crucially, a streamlined and consistent approach across its own decarbonisation division.
By July 2026, London Universities Purchasing Consortium was consulting on its Carbon Offsetting Services framework. That exercise focuses on cost‑effective strategies for reducing emissions and improving Scope 2 and 3 reporting for member institutions, explicitly combining advisory services with validation and reporting support.
Network Rail Infrastructure Limited, meanwhile, used July 2026 to trail an Eastern Region Sustainability Framework. That framework is intended to provide sustainability services for railway infrastructure and projects, giving project teams access to specialist advisory and technical support across a range of sustainability disciplines.
And in May 2026, National Highways Limited looked to the market through a Carbon Credits Market Engagement, seeking support both to secure carbon removal credits and to develop projects that require expertise in policy, finance and technology.
Together, these examples show public bodies treating climate and net zero governance as a specialist function that needs structured, often framework‑based support. The Defence Infrastructure Organisation’s net zero subject matter expert would sit squarely in this emerging landscape of embedded, client‑side climate expertise.
The phrase “Net Zero Carbon surveys and planning” in the Defence Infrastructure Organisation notice underlines the central role of data. Without credible surveys and inventories, net zero plans are difficult to prioritise, cost or track.
In April 2026, the Department for Energy Security & Net Zero launched market engagement for a Greenhouse Gas Inventory Improvement programme. That work focuses on developing methodologies, conducting sector‑specific research and improving emission factors in line with IPCC guidelines. It shows how centralised, methodologically robust inventories are becoming a priority area of spend in their own right.
Local authorities are making similar moves. In June 2026, Cheshire East Council began market engagement for Carbon Assessments for SMEs in its area. The council is seeking suppliers to deliver baseline assessments, ongoing emissions monitoring and carbon reduction plans, and is using the process to gather insight on delivery options.
In April 2026, Rotherham Metropolitan Borough Council issued a Prior Information Notice for Commercial Building Decarbonisation. The council is seeking market insights and data to support decarbonisation of 15 commercial buildings, as part of a commitment to achieve net‑zero operational emissions by 2030. Again, analysis and data gathering are built into the early stages of the project.
The trend is not confined to energy and buildings. In May 2026, the Department of the Environment (Environment and Climate Change Canada) sought scientific expert help through a contract notice for Expert Support for the Wild Species 2025 Report. That work aims to finalise a major biodiversity report while encouraging participation in the Net‑Zero Challenge and adherence to procurement policies, illustrating how climate goals and broader environmental reporting are increasingly linked.
Against this backdrop, the Defence Infrastructure Organisation’s focus on continuing net zero carbon surveys and planning points to a need to maintain consistent baselines, track progress over time and feed evidence into investment and policy decisions, even if the notice itself does not yet spell out these tasks.
Governance and data are only part of the picture. A growing number of procurements show how such advisory roles sit alongside frameworks and contracts for tangible decarbonisation works.
In May 2026, Northern Housing Consortium Ltd set out plans for a Sustainable Energy Products Framework. The framework will act as a product catalogue for sustainable energy and resilience products such as batteries and solar panels, with further engagement promised to refine the scope. Later that month, NEUPC Ltd began shaping a Sustainable Energy Solutions framework aimed at helping users meet their carbon reduction and wider sustainability goals.
The housing sector is also moving from plans to delivery. In July 2026, Cambridge City Council outlined a procurement for Energy Efficiency Works for Council Homes, covering insulation, renewable energy installations and structural repairs, with a contract anticipated to be awarded in early 2027. In June 2026, Thirteen Housing Group Limited described a Roofing and Decarbonisation Programme 2026-2028, combining decarbonisation measures with essential works to improve energy performance.
Karbon Homes added to this pipeline in June 2026 with a soft market testing exercise for Byker District Heat Network Decarbonation. The housing provider is seeking organisations capable of designing, building, financing and operating a low‑carbon solution for an existing district heat network, moving from gas‑fired generation to water‑source heat pumps.
Transport and industry‑focused buyers are also investing. In April 2026, Transport for London consulted the market on Zero Emission Fleet Infrastructure, aiming to install around 400 electric vehicle charge points to support a net zero vehicle fleet by 2030. That same month, Net Zero Industry Wales sought Regulatory Sandbox Development Support to enable regulatory experimentation around carbon capture, hydrogen distribution and electricity network use, with the aim of attracting investment and meeting decarbonisation targets.
Skills and communication are emerging as further pieces of the net zero jigsaw. In August 2026, Enterprise Cheshire and Warrington issued a contract notice for Clean Energy Skills Coordination, seeking consultants to implement a regional action plan for clean energy skills in collaboration with neighbouring regions. Also in August 2026, Cambridgeshire and Peterborough Combined Authority, on behalf of the Greater South East Net Zero Hub, sought Marketing and Communications Support to develop and promote case studies on net zero projects across public and community energy sectors.
Placed alongside these initiatives, the Defence Infrastructure Organisation’s planned net zero subject matter expert looks like part of a broader supply chain for decarbonisation services: from data and governance, through skills and communications, to construction and infrastructure delivery.
The Defence Infrastructure Organisation’s notice confirms an ongoing need for dedicated net zero governance support on the client side, but leaves most commercial and technical details open. It does not yet specify the value of the work, the precise responsibilities of the expert or how the role will interface with other programmes and frameworks.
If a full tender follows, points to watch will include how far the organisation expects its subject matter expert to shape strategy versus providing assurance and oversight, and how the work is aligned with the growing number of sector‑wide decarbonisation frameworks. For now, the PIN is another marker that a defence‑focused infrastructure body is joining the wider public sector in buying in specialist expertise to turn net zero ambitions into concrete plans and evidence.
