I would think very carefully before doing this. Once you're off "the ladder", it's very hard to get back on again.
With that level of debt, you might find it difficult to get a place to rent. Lots of agencies run credit and affordability checks and if you've got debt that you're struggling to manage you might not find it easy to get a rental. And rents seem to be rising inexorably, although this may not be the case in all parts of the country (I'm in the SE).
Also, there's lots of talk about landlords getting out of buy-to-let because of changes in the law if the "Renters' Rights" bill goes through without significant amendment. If that's the case, rental property will become scarcer and probably more expensive.
Before taking such a drastic step, I'd be going through my spending with a fine-toothed comb, looking to ditch any non-essential commitments, and shopping around for better deals on everything that is essential. Then spend a couple of months living like paupers, not buying anything that isn't essential. No new clothes, no nights in the pub, no grabbing a £5 coffee on the way to work (if you do that daily, you'd save £100 a month), no holidays, no picking up a new lipstick because you fancy it etc. Then you'll see how little it's possible to live on, and how much more cash could be used to pay down the debt. And keep a track of where your money is going, and budget for things.
There's loads of good advice on Money Saving expert on this stuff, it's well worth exploring. Especially the stuff about budgeting.
I used to be shit with money, buying something new to wear for every party, lunchtime in the pub with colleagues etc. It took having maxed out cards and not enough to live on to give me a wake up call, and I got it under control. I won't pretend it was easy, but it was worth it. And although my main job is welfare rights, I also coach clients in how to manage their money. I've never gone through someone's spending and not found ways they can make significant savings.
