Assuming that you're a UK citizen, the only countries which you have an automatic right to live and work in are those within the EU:

The only (almost entirely) English speaking country within the EU, other than the UK, is Ireland which has experienced an economic crash and which is hard to find work in.
However English is widely spoken (and almost universally understood) in Malta. Like all 'sunshine resort' countries there's likely to be plenty of competition for jobs there but it might be worth considering.
Which city are you in? Not all UK cities are the same. I'd be bored to tears in some of them (e.g. Peterborough) but others, such as Brighton, are vibrant, friendly and full of fun.
