Child Tax Credit is purely awarded on the basis of your income, and the fact you have a child.
UC is also based on your income, but in order to claim it, there are conditions attached (known as conditionality). It is much more stringent than CTC.
These are work-related activities claimants must do to get full entitlement to UC. You will be assigned to one of six conditionality regimes, based on an assessment of capability and circumstances.
DWP will decide which group you fit into, and therefore what commitments you must undertake to continue to receive the benefit,
1.Searching for work, not working or with very low earnings.-
Claimants must take action to secure work, or more or better paid work. The Work Coach supports them to plan their work search and preparation activity.
2.Working with requirements -
In work but could earn more, or not working but has a partner with low earnings
3.No work requirements -
Not expected to work at present. Health or caring responsibility prevents claimants from working or preparing for work.
4.Working, no requirements, -
Individual or household earnings are above the level at which conditionality applies. Claimants are required to inform DWP of changes of circumstances, particularly if they are at risk of decreasing earnings or losing job.
5.Planning for work -
Expected to work in the future. Lone parent or lead carer of child aged 1. Claimants are required to attend periodic interviews to plan for their return to work.
6.Preparing for work -
Claimants are expected to start preparing for future, even with limited capability for work at the present time or a child aged 2, the claimant is expected to take reasonable steps to prepare for work including Work Focused Interview.
You will probably have a face to face interview initially to start your claim and verify your identity and circumstances.
Usually, if your child is between 5 and 12 years old, you will be required to work (or search for work) of at least 25 hours a week.
If your child is over 12, you will be required to work full time (35 hours a week).
There are also other rules related to UC, such as how much savings you can hold before your benefit is restricted.
