trixietrossel: if you are talking about the fixed term deposits that banks & buidling societies sometimes call bonds (as opposed to government bonds, corporate bonds, equity bonds, etc), then yes.
robwin123: maxsteam is generally right, but all generalisations are suspended in this climate! I'd hardly call the Nationwide an odd, small building society (they are, in fact, the biggest) and yet they are on the government's recapitalisation list. See this FT article: www.ft.com/cms/s/0/decd5e02-950b-11dd-aedd-000077b07658.html
The FSA is also waiving the usual rules so the Nationwide can quickly merge with the Derbyshire and the Cheshire, as both of those are facing difficulties. See www.ft.com/cms/s/0/1d66b916-7d82-11dd-bdbd-000077b07658.html
The safest places for deposits are NS&I and (now!) Northern Rock -- both are owned by the government (anyone worried that the government, and hence the country, might go bust should invest in 10 years of rice and dried beans, and a shotgun! :-)
In reality, what we've observed so far is that the government will do everything it can to protect all retail deposits in UK banks & building societies, either by nationalisation (Northern Rock) or by facilitating rescues (HBOS, Bradford & Bingley, Kaupthing Singer & Friedlander, Heritable) or, in the case of UK branches of foreign banks (Icesave) by neo-gunboat diplomacy and brute legislative force!
