Anyway, as my name gives away, I had (still have, unfortunately) money in Landsbanki Guernsey, and I found that everything the site reports about Guernsey is right. Dunno about the IOM and Jersey pages, but I suspect the same is true for those as it's all backed with scores of links to newspaper articles and official sites, the islands' compensation schemes, even the OECD. Cos of all the links and references I found this to be the best all-in-one-place reference on the matter, but each to his own.

Re R85, it's the no-hassle option, just file it once with each bank and that's it, no messing with reclaiming tax every year. Of course it's not kosher, but neither is giving banks a "false" address and leading them to believe you're resident when you're not!

Also, if you're in that league, UK banks will give you interest gross if your deposit is over £50k anyway.
