Actually, it's £820 + £8 for the foreign nationals, or £1020 if you do it in person.
To process the application, their current target is "95% within 6 months"
In the meantime, you may not get a job, change jobs, move house, get married, get divorced, leave the country, go to Northern Ireland or do anything at all.
They also require your Passport *and* 'ID Card' while the stuff is being processed, giving you a single three or four page letter that supposedly 'proves' to your current employer that you're still allowed to stay in your job.
Said employer is then pretty nervous, given the possibility of an up to £10,000 fine for not reading it properly. So they're quite likely to fire you.
On top of that, they require your partner's Passport while they do it - and they then have absolutely nothing to 'prove' that they are allowed to stay in their job. In fact, if they don't drive they're left with no forms of photo ID whatsoever - a fact which universal 'ID cards' wouldn't change, because they'd have been asked to send it in as well (see above).
Getting married has so far cost us just shy of £3000, purely for the Home Office paperwork.
It rather trashed the day itself - no budget left.
(Anon because the Home Office hold my life in their hands right now.)
