Hi fiz,
This is something that you can only decide for yourself, but remember if you challenge it, that it can also go against you, as well as for.
Me personally, the way the government is changing things, and toughening up, I'd look at it as, something is better than nothing, in relation to your award.
If you're finding things tough financially, you can always look on the money saving expert website and see if you can do anything that may give you a little financial boost, a payrise in a manner of speaking, by doing things such as:- Changing your suppliers for Energy, Broadband, and Television for example.
I review mine every year, then that way it seems as if my money is going further, although I do appreciate that during this C.O.L crisis, things can be tough.
Hope this helps,
Regards, Chris
