The Dept of Communities has just announced a new £15.5M Covid-19 Charities Fund to help local charities facing financial difficulties as a result of the current public health emergency https://www.communities-ni.gov.uk/news/ps155m-fund-support-charity-sector-during-covid-19-crisis-open-monday. This is part of a wider national package of Government support for the charity sector.
The fund will open for applications of up to £75k on Mon 15th Jun and will be administered by The National Lottery Community Fund, so please have a look at the web pages for details of how to apply: https://www.tnlcommunityfund.org.uk/funding/northern-ireland
Charities with a national presence should note that although only one application can be made on behalf of any organisation within one nation, this is not the case across the nations. The same organisation could therefore apply for a grant in a different nation (or nations).
