The partnership will allow Nectar points to be transferred in a variety of ways, such as donating a percentage of the total points collected or transferring all points for a specific time period. A minimum of 250 points can be donated via a hotline, for which Nectar will contribute £1.25 to the Nectar Children in Our Community Projects.
The charity will feature heavily in Nectar's direct mail quarterly updates, which are sent out to its 13m members.
When Nectar was set up, it had four charities, which were nominated through its key sponsors, Sainsbury's, BP, Debenhams and Barclaycard. But Richard Campbell, marketing director at Nectar parent Loyalty Management UK, said it had always wanted to choose an exclusive charity partner to give a more focused charity redemption offer.
In January, Nectar signed up Cannons Health & Fitness as its exclusive health and fitness redemption partner.
It is also expected to reveal tie-ups with car rental firm Hertz and kitchen retailer Magnet in the next few days, although Campbell would not confirm the partners.
Speculation over Debenhams' review of its involvement in the programme is expected to result in the department store remaining a major partner.
Last year Nectar announced that more than half of all UK households had signed up to the loyalty programme.
