Benefits should never be a lifestyle choice. Ever.
I am horrified at the number of people essentially telling the OP how she can play the system to keep claiming benefits and get £26k into the bargain.
I have actually just applied to go on UC Because I am a single parent, am unemployed and money is tight. I find the idea of applying for benefits horrifying. Worse yet, I am likely to be rejected because I am unemployed and because I am unlikely to be able to find work as I am VI and the number of people with VI out of work is roughly 85%. But I am required to speak to a job coach, required to commit to taking any work which comes up (someone I know was sanctioned because they refused to apply for a job as an amazon delivery driver,) I also have to commit to travel 1.5 hours each way to/from work.
I have been looking for work for a considerable amount of time now and actually had a job offer withdrawn because of accessibility. And yet the amount of people who have said to me “you should try to convince them that you’re incapable of work (I’m not, I’m just unlucky) and well, everyone else does it so why shouldn’t you?”
Where on earth is the self respect in that. If someone left me £26k it wouldn’t even have occurred to me that it might affect any benefits I might want to claim.
We need to get away from this attitude that benefits are a lifestyle choice.
If you have £26k then you live on that. Appropriate it into your living costs to make it last longer, and when it runs out, then go back on UC.
