UK Public Sector Contracts & Tenders

CASA3 is a strategic International Climate Finance (ICF) programme that strengthens the capacity and capability of climate-vulnerable developing countries to participate effectively in international climate negotiations. The programme contributes directly to UK Government priorities by supporting ambitious, inclusive and rules-based international climate negotiations, enabling developing country partners to engage as progressive voices within the United Nations Framework Convention on Climate Change (UNFCCC) and associated multilateral forums.

The final date and time for the submission of bids is Wednesday 7th October 2026 at 11:00 DO NOT apply directly to the buyer. All tender information MUST be submitted through the Jaggaer eSourcing Portal. Brief Description of Requirement Phase 1 The objective of phase 1 is to assess the safety and risk considerations for deployment of up to 800 W AC mains output plug-in batteries in the UK context with acceptable electrical and fire safety risk. The study will inform technical standards adaptations and assess the feasibility of safe, plug-in batteries for UK domestic use. A relevant set of installation configurations will need to be considered in scope of the fire and electrical safety tests and will be finalised as part of the test protocol development for the study, in consultation with relevant stakeholders. These installation configurations may include individual plug-in batteries, plug-in battery DC-coupled to plug-in solar with a single hybrid inverter, multiple plug-in batteries DC-coupled in series, and multiple plug-in batteries DC-coupled in parallel. An illustrative set of installation configurations that might be expected to be considered by the supplier when developing the test protocol are provided below, noting that the tests should focus on the standalone plug-in battery products and/or the plug-in battery to plug-in solar interface rather than the wider domestic environment in which they are located.

All tender information MUST be submitted through the Jaggaer eSourcing Portal. Brief Description of Requirement It is broadly recognised that physical climate risk and related nature dependencies can pose risks to economic and financial stability. Governments and regulators in the UK and internationally have recognised this and continue to take action to address underlying vulnerabilities and support wider systemic resilience. Notwithstanding the clear need for accelerated global action, there remains significant uncertainties in appraising the future economic and financial implications of physical risk meaning market practices, government policy and regulation, may not be optimised (within the bounds of wider limitations and mandates) to align with climate-resilient pathways. Climate scenario analysis is a key tool to inform approaches to climate risk management. But due to the complexity and heterogeneity of climate risk, academic and industry evidence has highlighted that current mainstream scenarios – whilst highly sophisticated – may not capture all potential physical risk due to limited data availability and modelling constraints. Furthermore, whilst reference scenarios continue to be enhanced, some potential hazard exposures and highly complex systems dynamics may not be well suited to quantification through empirically calibrated, top-down damage functions, which provide estimates for economic damages in climate scenarios. There is, therefore, a need to investigate the potential for complementary methodologies to support more holistic approaches to physical risk appraisal and management. This is the focus of this research project. Specifically, research will focus on how local physical climate shocks (e.g. storms, flooding, droughts, heat stress) can - through cascading, compounding, and contagion effects - become systemic risks. There will be a particular focus on furthering understanding of UK vulnerabilities to climate shocks in other countries, with the objective of supporting improvements to industry practices and providing insights for government policy, regulation, and prudential supervision. This research project will be delivered in coordination with the Financial Conduct Authority’s Climate Scenarios Sandbox , with potential for insights generated through the sandbox to provide practical evidence regarding the utility of research outputs. The project will also be delivered in partnership with the recently established UK Taskforce on Climate and Nature Security and will, where possible, be aligned with ongoing work on high-impact climate possibilities at the Climate Financial Risk Forum.

DESNZ is seeking supplier(s) to deliver research on opportunities for effective and responsible research and/or deployment of non-CCS reliant GGRs, including biochar, enhanced weathering (EW) and marine carbon dioxide removal (mCDR), over timescales relevant to meeting our carbon budgets and net zero targets. The programme will provide targeted evidence for near-term policy milestones, examining: the real-world performance of these GGRs; approaches to monitoring, reporting and verification; suitable UK conditions for research (mCDR) and deployment (biochar, EW), and feasible UK-specific delivery pathways; and associated barriers, opportunities, risks and benefits. Given the breadth of technical expertise and range of anticipated methods required (e.g., evidence review and synthesis, stakeholder engagement, pathway development) and outputs (e.g., briefings, databases, case studies, teach-ins) DESNZ anticipates a consortium of suppliers will deliver this research.
