Climate tech covers companies building products, services, and infrastructure that reduce greenhouse gas emissions or help organisations adapt to a changing climate. In the UK, this spans renewable energy developers, carbon accounting platforms, sustainable materials firms, grid-flexibility software providers, and climate risk analytics businesses. UK-based operators such as Octopus Energy, Xero-integrated carbon tools like Sweep, and battery storage specialist Zenobe Energy represent the breadth of activity BF monitors in this space.
BF tracks climate tech because regulatory pressure and corporate procurement decisions are reshaping supplier relationships across almost every industry. UK SMEs face growing requirements around emissions reporting, whether through their own obligations or those of larger customers demanding supply-chain data. Understanding which climate tech providers are gaining traction, which business models are proving durable, and where public funding is flowing helps operators make informed decisions about their own compliance, procurement, and positioning.
Several tensions will shape the sector over the next one to two years. Can carbon accounting platforms standardise their methodologies sufficiently to satisfy auditors and regulators, or will fragmentation persist? Will the economics of clean energy infrastructure remain attractive as interest rates and supply-chain costs fluctuate? And as the UK refines its net-zero policy framework, which compliance obligations will extend meaningfully to smaller businesses, and on what timeline? These are the questions operators in adjacent sectors need to watch closely.
