If you have an award that is longer than two years then it should, if it is two years then it will depend on whether it was classed as a long term award or a short one, if the former then it should apply.
If two years (short award) or less than two years then there may be problems, although the law does not differentiate between Fixed Term awards the DWP appear to be applying different criteria and they may not extend your award.
