Council tax benefit is EXTREMELY hard to get. Okay, nearly impossible. Put it this way: I was once supporting 3 people on £13,000/pa - gross - and didn't qualify for ANY council tax benefit.
If you, your partner or any of your children are registered disabled, however, you may qualify for some.
My pensioner ILs don't qualify for council tax benefit.
If you're a renter, you may be entitled to housing benefit. It's worth applying.
Are you working? If you are earning under £15,000, you may qualify for Working Tax Credit. You may also qualify for Child Tax Credit - same application form.
