ActionAid’s income fell by almost 10 per cent in 2018, the latest figures show.
The charity’s accounts for 2018, filed with Companies House this week, show an income of £49.6m, compared with £55m the year before.
The bulk of the fall was down to a £4.8m drop in the total amount of grants awarded to the charity, down from £12.1m in 2017 to £7.3m last year.
Funding from the Department for International Development, for example, fell by almost two-thirds from almost £2.1m to £733,000 in 2018.
Expenditure by the charity also fell, from almost £60.9m to £46.6m over the same period.
The accounts show that a fall in spending on charitable activities from £51.7m to £36.3m was the main reason for the drop in expenditure.
This was partly because of a significant fall in the amount spent by the charity on emergency and humanitarian response, from £10.6m to £2.9m.
Ed Tait, director of fundraising at ActionAid UK, said: "Like many charities, we’ve found that the fundraising environment at the moment is complex and challenging.
"But we’ve been encouraged by some real successes with less traditional forms of fundraising, such as last year’s Not This Girl appeal, which saw DfID match donations from the public to help girls who’ve survived violence in Kenya.
"We have faith in our new strategy, which will see our fundraising and campaigning increasingly focus on securing the rights of the women and girls with whom we work in the poorest countries."
