I think finding a local locksmith is probably your best bet. Should be less than £ 100 to include a quality british standard five lever replacement lock.
As you hint that your DIY skills are perhaps not great I can see you spending over that amount in tools, parts, time and effort.
Ask friends, workmates and relatives for a recommendation.
