Social landlords Adra, Grŵp Cynefin and partners have created jobs in a bid to decarbonise homes in Gwynedd.
Project Sero Net Gwynedd has received £589,203 of funding from the UK Government through the UK Community Renewal Fund, with an additional £195,000 of match funding from partners.
It was part of £46m received in Wales this year as part of that UK fund - although critics of the fund allocation say that it compares to the £375m Wales would have had over the financial year from the EU, which UK Government had promised to match after Brexit.
