Paul Reddish, chief exectuive of Volunteering Matters, said: “This year the nations’ charities have been critical to so many. They’ve been at the heart of much of the Covid-19 response – from delivering food to supporting those most isolated in every community throughout the UK.
“Their staff and volunteers continue to provide these vital services, such as end of life care and key support for the vulnerable, despite the ongoing conditions created by this pandemic.
“Charities have seen demand rise but are also expecting to see more than a £12 billin loss in 2020.
“One in 10 charities are at risk of closure if things continue as they are. Charities and organisations that do manage to survive will face major constrictions to operate the way they once did.”
