Vicky Burn, deputy editor of MoneyFacts, a financial data magazine, says the big bank Goliaths were beaten hands down by the tiny building society Davids in its annual round-up of Tessa payout values.
The lucky saver who put pounds 9,000 into the top-performing Tessa from the Chorley & District building society in January 1993 would have reaped pounds 618 more than in the poorest one provided by Cater Allen Bank.
The magazine's performance chart shows that for Tessas taken out five years ago only one of the high street lenders comes in the top 20. This was with TSB. Halifax is the next big player but is well down the list at 25.
The rest of the nation's big hitters languish near the bottom end. Of the 92 Tessas monitored, NatWest came in at 73, Lloyds at 74, Midland and First Direct at 75 and 76, while Barclays' offerings were at 59 and 86.
Eight of the top 10 providers to January 1998 are building societies that have retained their mutual status. National Counties, at number 10, has just one branch.
Of the other top performers, Buckinghamshire, Tipton & Coseley and Holmesdale building societies, at five, six and eight respectively, are so tiny that they refuse to accept savers from outside their localities.
The largest mutuals, however, have failed to keep up with their smaller brethren. Bradford & Bingley's "High Return" product came 47th, Britannia BS was 57th and Nationwide came 62nd. The Consumers' Association says building societies were ahead of the banks in general because the banks need to make bigger margins to satisfy shareholders. Mick McAteer, senior policy researcher at the association, says 40 per cent of the banks' post- tax profits were paid in dividends. Stephen Bullock, the chief executive of Chorley & District building society, says: "The absence of shareholders has meant that building societies could improve rates by 0.4 per cent over their plc counterparts."
Mr McAteer says that the larger societies, which offer poorer value on the Tessa side, have keener rates on mortgages in general. Mr Bullock believes smaller societies can pay better rates because they are more specialist. Big societies such as Bradford & Bingley have diversified into a broader range of products.
Mark Hamilton, of the Nationwide, agrees with this. He says: "Tessas are the smaller societies' flagship products."
