IANAL so you will need to check if it is important for you. The change in double jeopardy in the UK is related to only the most serious cases, possibly only murder. It is the result of forensic advances, principally in DNA collection and analysis, that make old cases safely (hopefully for high values of safe) open to retrial.
I have ambivalent feelings here. I am happy for evil people to get their just deserts but am also aware of the start of a slippery slope. So far there have no calls that I know of to expand the crimes open to retrial in the case of a not guilty verdict.
