Pip is paid to more than 3.6 million people who have a long-term physical or mental health condition in England, Wales and Northern Ireland.
There are two elements - a daily living component and a mobility component. Claimants may be eligible for one or both.
Under the government's proposals, assessments for the daily living part will be tightened, which the official forecaster - the Office for Budget Responsibility (OBR) - says will affect around 800,000 people.
Pip assessments involve questions about tasks like preparing and eating food, washing and getting dressed. Each is scored on a scale from zero - for no difficulty - to 12 - for the most severe - by a health professional.
From November 2026, the government says people will need to score at least four points for one activity, instead of qualifying for support with a score that could describe less severe difficulties (ones and twos) across a broad range of tasks.
For example, needing help to wash your hair, or your body below the waist, would be awarded two points, but needing help to wash between the shoulders and waist would equate to four points.
The payments for daily living are:
Payments for the mobility element - which are not affected - are:
Pip is usually paid every four weeks and is tax-free. It does not change depending on your savings or income and does not count as income affecting other benefits, or the benefit cap, external. You can get Pip if you are working.
At present, the payment is made for a fixed period of time between one and 10 years, after which it is reviewed. You may be reassessed sooner if your circumstances change, external.
The government plans more frequent reassessments for many people claiming Pip. However, those with the highest levels of a permanent condition or disability will no longer face reassessment.
There is a similar but separate benefit in Scotland called the Adult Disability Payment, external.
