Grocer Morrisons is to donate £100,000 to help those affected by flooding in Greater Manchester, Yorkshire, Lancashire, Scotland and Cumbria.
The donation is the latest instance of food retailers assisting communities hit by the storms which have battered parts of the UK in recent weeks.
The money will go towards clean-up costs, repairs and emergency supplies of clothing, food and drink.
Morrisons chief executive David Potts said: “We have seen the terrible impact that the floods have had on communities that we serve and we want to do our bit to help.
“This money will help to start the clean-up process which will be a huge challenge over the coming days and weeks.”
The grocer has already given food and other emergency supplies to crisis centres. Staff have run collections and donation stations and in-store cafés have been used to provide free meals for displaced families.
Some stores, in some instances the only food retailers in affected towns, have been among the properties flooded.
There was concern about more flooding as Storm Frank hit the country, and many flood warnings remain in place.
