Mr Clemo said: "What we have seen is that around three-quarters of organisations operated on some level throughout lockdown but we are increasingly seeing that fall of income result in cutting the cloth with reducing services and redundancies."
He added that there had been a "perfect storm" of financial struggles combining with increasing demand for services due to the demands of community hardship and mental health during the pandemic.
Sean Moore, chairman of Norfolk Blood Bikes, which transports urgently required medical items to hospitals in Norfolk and the East Anglian Air Ambulance, said the loss of supermarket collections, fetes and carnivals had a big impact financially.
