Heating and Cooling tenders — page 2
150 listings tracked right now · page 2 of 4
Grants and schemes for heat pumps, district heating and clean cooling. The cheques come from UK DESNZ (heat networks and the Boiler Upgrade Scheme), the US DOE, EU LIFE and Horizon, and utility and municipal heat programmes. Listed below are the open heating and cooling tenders and contract notices that landscape produces, taken from each buyer's own notice and re-checked on every refresh.
This is one of the highest-volume procurement areas on the site, because every local authority, housing association, hospital trust and university buys retrofit, heating and building services. Contracts arrive as frameworks and dynamic purchasing systems more often than as single awards, and getting onto the framework is the real competitive event rather than the individual call-off.
This page lists open heating and cooling tenders and public contracts currently tracked by Raise Lens — 150 of them right now, sorted with the soonest deadline first. Every listing has been classified against the sustainability taxonomy rather than matched on keywords, so what appears here is heating and cooling work rather than anything whose description happens to mention it.
47 distinct buyers are publishing the heating and cooling tenders and public contracts on this page. Who is funding matters as much as what: eligibility, reporting burden and the realistic timeline to a decision vary far more between buyers than between individual calls, which is why the listing names the buyer on every opportunity it opens.
41 of these close within the next 30 days. Deadlines are taken from the source listing and re-checked on every refresh, but the originating buyer remains the authority — always confirm against the official notice before you submit.
