The scheme, run by the Pennies Foundation, asks people who buy items by credit or debit card in shops or online if they would like to round up their bills to the nearest pound, with the difference going to charity.
Since becoming the first retailer to launch the scheme in November 2010, Domino’s customers have donated a total of £230,000 to charity, a statement from the Pennies Foundation said.
Seventy-five per cent of the money raised in the UK went to Special Olympics Great Britain, while 75 per cent of the money raised in Northern Ireland went to the Northern Ireland Children’s Hospice. The other 25 per cent was shared between other charities, including Shelter and the NSPCC.
The most common amount donated was 1p.
The Pennies scheme is being used by seven other businesses, including Travelodge and Zizzi restaurants. So far, Pennies has raised almost £400,000 for 27 different charities, according to a spokeswoman, and people had donated through it 1.6 million times.
Lance Batchelor, chief executive of Domino’s Pizza, said: "In these times of economic hardship, it is heart-warming to know that people are still happy to share what they have."
