There are some risks with any provider of ISA accounts, but there is FSA cover on virtually all of them, except those rare situations where there is more than £50,000 [previously £35,000] in the account. Incidentally, the ISA from the NatWest is for transfers of £27,000 or above, so you would need to open an account with this year's ISA subscription but only if you have not already subscribed from £1 to £3,600 in an ISA since 5 April 2008.
