Tailoring your CV is a good start. But IT is a broad term -- it's like saying I'm a 'writer'. Your particular focus within that field, whether there are any UK-specific qualifications needed for that focus, where you'll be living, access to transportation, etc, will all inform your marketability.
My specialisation (medical writing) happens to be generally highly sought-after, but particularly in London (where I live). I was interviewing within a few weeks (also started pulling pints in my local 5 days after landing, just to get out of the flat), then had my pick of three jobs after doing 2-3 interview rounds. I accepted the best of the lot 6 weeks after landing, hustled to build up a new freelance network on the side and, after 2 years with the original employer, was lured away by one of those freelance clients.
But this is not a typical situation -- because there is no 'typical'. I might have been working sooner if I'd been a senior-level web developer, or had a tougher time if we'd been based in Leicester instead of London.
Get a feel for the market before you move, and adjust your expectations -- for salary and availability -- accordingly. Determine whether you'll need to brush up skills or get qualifications once you're here. Tailor your CV according to the market for your new location. Reach out to agents. Make your LinkedIn sparkle (and agents will reach out to you). Post your CV on a large site like Reed.co.uk or one more specific to your industry. Join a professional organisation, if one is available in your area.
But no two timelines or experiences will be the same, so simply asking 'how long?' isn't going to provide you with any statistically significant data.
