Moving
I also moved from Bristol to London and knowing hardly anyone, opted for a house share. Depending on location (probably aim for zone 2 for optimal time into work / cost) expect to pay between £300 and £600 p/m for a house share depending on the state of the place.

As long as you choose your potential house mates well, there is a lot to be gained from this approach.

As Monty mentioned living costs don't have to be expensive, an unlimited zones 1-2 travel card is ~£90, covers the major areas and is probably the only additional expense you'd have moving from Bristol to London.

Feel free to Gaz if I can give you any better details
