Totally up to you, grad schemes they run throughout till like Easter time when assessment centres happen(of course some finish sooner), local jobs you could write speculative letters, scan grad jobs sites like me ( i seem to find a new site everyday, there's literally hundreds of them) or check out normal job sites, jobcentreplus,monster,reed.co.uk etc.. the list is endless, get your google shoes on, and in imo do it sooner rather than later!!!
