Skipton Building Society and the National Society for the Prevention Of Cruelty To Children are joining forces to launch the cash based NSCPP-ISA.
For every £1,000 invested in the Isa, Skipton will donate £5 to the NSPCC's Full Stop campaign. The minimum investment is £3,000.
Additionally, 0.5 per cent of the interest on the customers balance will go to the charity each year.
The move is hoped to raise over £500,000 for the NSPCC on top of the £400,000 raised by Skipton in 1997, when it insisted carpetbaggers make a donation of £25 each to the charity.
