There was a sharp rise in charitable donations on Giving Tuesday, which took place this week, according to the Charities Aid Foundation.
CAF said it was not yet able to put a figure on how much was raised for good causes on the day, which it brought to the UK for the first time this year, but that various sources had reported large increases in charitable donations.
For example, the software provider Blackbaud reported that UK donations were up by 270 per cent compared with the same day last year. And the online giving platform JustGiving said that total donations rose by 46 per cent compared with the same day last year.
Stewardship, which promotes tax-efficient giving, reported a 16 per cent increase in donations against the same day last year.
Localgiving.com, which helps small charities to fundraise, said it raised £75,736, almost 10 times what it raised on the same day in 2013.
The payment services company Visa Europe said that donations were up by 10 per cent on last year and that in the UK more than £2,500 was donated every minute through its cards. This would amount to £3.6m if multiplied over 24 hours.
#GivingTuesday was trending on Twitter for 11 hours over the course of the day, CAF said.
The social media analytics company Crimson Hexagon said that 30,000 tweets were sent in the UK using the hashtag, peaking at 11am.
The event was started in the US in 2012 to encourage the public and businesses to do something charitable on the Tuesday after Thanksgiving, the national holiday celebrated in the US. It now runs in Australia, Canada, Israel, Mexico and Singapore.
Third Sector revealed in May that CAF was planning to bring the day to the UK for the first time this year.
Hannah Terrey, head of policy and campaigns at CAF, said it was inspiring to see how much the UK had embraced the day.
