Charitable donations handled by the Charities Aid Foundation fell by almost £34m to £505.3m last year, but "still exceeded expectations", the charity has said.
CAF’s annual report for the year to the end of April shows that the amount given to charities by CAF was down from £539.1m in the previous year, but that was a record total "reflecting exceptional levels of giving in 2016/17", CAF said.
It is only the second time the amount has exceeded £500m.
CAF, which provides services including bank accounts for donors and charities and payroll-giving schemes, said it handled donations to charities in more than 110 countries in 2017/18.
It said the overall amount of giving by people and companies through CAF in 2017/18 was £607m, down from a record £611m in the previous year.
CAF recorded a total income of £597.7m in 2017/18, down from £604.7m in the previous year. Total spending was £482.5m, down from £516.3m in 2016/17.
It had £2.5bn in total assets at year-end, up from £2.4bn 12 months previously.
Sir John Low, chief executive of CAF, said: "We continued to be humbled by the enormous generosity of the many thousands of people and businesses that choose to support the work of many amazing organisations through CAF.
"We are proud to be able to help them support charities both in the UK and around the world. Their remarkable levels of giving have remained resilient though uncertain times, a reflection of the deep-rooted tradition of generosity, particularly in the UK and USA, our largest markets."
