If you are working and earning through permitted work while you are claiming Income Related ESA, you need to inform the DWP if your income goes over £131.50 per week after tax and National Insurance. You may still qualify for help through Universal Credit. Once you get Universal Credit you cannot go back to the old benefits.
When you claim Universal Credit:
your old means-tested benefits stop
you will not get a payment for at least 5 weeks, but you can get an advance payment to cover you. You need to repay this over 12 months.
Benefits for people who are sick or disabled (not means-tested)
Personal Independence Payment (PIP) and Disability Living Allowance (DLA) cover the extra cost of being disabled. They are not affected by your income, and you can claim them even when you earn more.
If your increase in income (for example, you are working more hours) suggests that you can do things that you could not when you were assessed for PIP, this might lead to a re-assessment. This could reduce or stop your PIP payments.
The other non-means-tested benefits for sick and disabled people are:
Attendance Allowance (only if you are retired)
Armed Forces Independence Payments (instead of PIP)
Industrial Injuries Disablement Benefit
Constant Attendance Allowance (if you became disabled after getting injured at work or fighting in the armed forces)
You should be better off by 37p for every pound you earn above your ‘work allowance’. Your work allowance is how much you can earn before your Universal Credit is reduced.
When you’re in work, the tax office updates the DWP about your earnings.
pay rise means that you no longer qualify for Universal Credit, you do not need to sign off
earnings reduce within 6 months, your claim will still be live and you’ll start receiving Universal Credit again
For example, if you were claiming Universal Credit, but earned more in December so you did not qualify for Universal Credit that month, you would start receiving it again if you earn less in January.
