People should "do a bit of research" when deciding on what savings account to get, one expert advises.
Jason Clarke, a spokesperson for Halifax, said that current economic uncertainty meant that banks were changing their savings account deals on a regular basis.
He recommended that people use several price comparison sites to make sure that they are getting the best savings account they possibly can.
Mr Clarke said: "Look for consistency across all of the different sites; if something is coming up in the top three across all of them then the chances are that it's a decent product."
However, he warned that if someone finding a good fixed-rate savings account should not expect it still to be available in a few weeks' time.
In December 2007, HBOS predicted that the amount of money in individual savings accounts would rise by £30 billion to a total of £240 billion in 2008.
