United Kingdom climate tenders
99 open listings, soonest deadline first.
UK climate funding is split between departmental programmes and arms-length agencies. The consistent sources are DESNZ and the Net Zero Innovation Portfolio, Innovate UK and the wider UKRI councils, ARIA for high-risk research, Ofgem network innovation funds, and the National Lottery Community Fund for community-scale environmental work. Listed below are the open climate tenders and public contracts in the United Kingdom that landscape produces, taken from each publisher's own notice and re-checked on every refresh.
Public procurement here is published to EU standards, which means notices are structured, deadlines are firm, and above-threshold contracts appear on TED as well as the national portal. Expect prequalification before the tender proper on anything substantial, framework agreements rather than one-off purchases, and scoring that weights technical merit and social value alongside price.
This page lists 99 open climate tenders and public contracts covering the United Kingdom, soonest deadline first. Every listing has been classified against the sustainability taxonomy rather than matched on keywords, and geographic coverage is read from the notice itself, so a programme open to the United Kingdom through a wider European or global scheme appears here too.
36 distinct buyers publish the calls on this page. Who is behind a call matters as much as what it funds: eligibility, reporting burden and the realistic timeline to a decision vary far more between buyers than between individual calls, so it is worth opening a listing before judging the programme.
The work on this page spans Climate Fintech, Renewable Energy, Energy Storage, Energy Efficiency, Heating and Cooling. Narrowing to one of those is usually a better use of time than reading the whole list, because eligibility tends to follow the sector far more closely than it follows the country.
Award sizes currently run from roughly £148K to £90K, which is the honest range rather than the headline figure.
28 of these close within the next 30 days. Deadlines are taken from the source listing and re-checked on every refresh, but the publishing body remains the authority, so confirm against the official notice before you submit.
