The RSPCA is set to become the latest player in the financial services industry with the launch of savings and loan products next month.
If successful, the RSPCA says life insurance and mortgages could follow.
The charity will launch the products with one-off news paper ads and inserts. It follows the successful launch of an RSPCA affinity credit card.
Charities Help The Aged and Mencap have already moved into into the market with some success.
RSPCA head of fund-raising Anthony Baumann says the society is "throwing some mud at the wall and seeing how much will stick".
The marketing is being handled by TransNational, which recently launched an affinity credit card with Arsenal Football Club and runs several more linked to other Premiership football clubs.
The RSPCA savings and loans products will be provided by the Bank of Scotland, which has become involved in a range of joint ventures, including Sainsbury's Bank.
Baumann says: "TransNational runs our credit card through the Bank of Scotland and that is where the link comes from. This is just a test so the launch will be low-key. We are being cautious because, unlike Help the Aged or Mencap, which have a logical group of customers, we are a bit different.
"We are trying to target younger people who do not normally give to charity. We are trying to make it easier for them. Our turnover is £40m. We have been tarred with the big-business brush and we have to make sure the service we provide is up to scratch."
