I'm writing from iBank's developer, IGG Software, so forgive any evident bias here. But I do wish to point out that, particularly with iBank 5's Direct Access subscription service, many UK banks are supported for automatic updating of transactions. You can download a trial copy of iBank from our website, and start a free 30-day trial of Direct Access as well. It may be the solution you are looking for, without switching banks.
On the subject of Direct Access, I should point out that it is not a requirement for users of iBank who are satisfied with direct downloads via OFX (or simply downloading a current transaction file from online accounts). But some banks charge for direct connections, while Direct Access streamlines, automates and even improves account updating in some cases - showing pending transactions, for example, when standard updating does not, and accessing many more banks internationally. So for some users this optional service will be worth its cost.
Also, I want to add my .02 to any questions and comparisons to both Mint and YNAB. Mint is free - not usually a bad thing - but is a limited tool for active money management (as pointed out elsewhere above). By the same token, YNAB offers good budgeting tools and dispenses good advice, but as our iBank comparison charts (linked to above by others) show objectively, YNAB does not provide for bank downloads, mortgage tracking, bill pay, check printing, tax export or investment support - etc. - while iBank 5 does. Those features are pretty essential, and hardly constitute "bloat" (as someone said), for anyone seeking full-featured money management.
In any case, we encourage people to monitor their finances, however they go about it. iBank 5 is just one solution out there, and we're happy to have interested users give it a test drive. Trial downloads and more info are at our site.
