The open call aimed to cast a wide net for impactful projects and provide Efficiency for Access with market intelligence on emerging technologies and the barriers and issues they face. The R&D Fund committed to supporting a wide range of technologies and products from cross-cutting horizon and enabling technologies to near-to-market products.



Efficiency for Access received 65 applications for the 2019 open call. Of the 65 applications, 41 projects totalling £5.1m were deemed eligible for review. A panel of experts reviewed the 41 projects and shortlisted 12 projects for due diligence. A portfolio approach was employed to ensure funding was spread across technology areas, geographic locations, stages of R&D, and project lengths and costs.

Nine projects were supported totalling over £1m in funding. An additional £680,000 in matched funding was unlocked from the nine recipients.

The open call also received 13 cooking appliance applications, of these, 12 were assessed in partnership with the Modern Energy Cooking Services (MECS) programme and six projects were awarded funding totalling approximately £750,000 from MECS.
