Hi CrazyAbout Bunnees
Review forms are typically sent out a year before the award end date - so you have received it in the time frame that you would have expected if yours is due to end next March 24.
Get your partner to ring the DWP again and ask for an extension. You will be given a further two weeks. If you find you need a second extension ring in plenty of time and request one. They have been giving out second extensions, but it's not a given and you don't want to leave it until the last moment.
