What Illnesses Qualify for the Personal Independence Payment (UK)? 2026/27

Advisors and practitioners frequently face questions from clients regarding state support, primarily: what illnesses qualify for the Personal Independence Payment (UK)?

The fundamental principle governing the Personal Independence Payment (PIP) is that the Department for Work and Pensions (DWP) does not base eligibility on having a specific named medical condition. Instead, eligibility depends entirely on how a physical or mental impairment functionally impacts a claimant’s daily life.

This guide breaks down the legal eligibility framework, the 2026/27 financial rates, and the distinct rules that apply to Scottish residents.

The Functional Impact Test: It Is Not About the Diagnosis

The UK legal system generally avoids prescriptive lists of qualifying disabilities. The criteria used for PIP heavily mirror the statutory definition of disability found in section 6 of the Equality Act 2010.

Under this legislation, a person meets the definition of disabled if they possess a physical or mental impairment that generates a “substantial and long-term adverse effect” on their ability to perform normal day-to-day activities.

“(1) A person (P) has a disability if— (a) P has a physical or mental impairment, and (b) the impairment has a substantial and long-term adverse effect on P’s ability to carry out normal day-to-day activities.”

The Equality Act 2010 does not contain an exhaustive list of qualifying illnesses.  However, the legislation does expressly designate a few specific conditions as automatic disabilities from the point of diagnosis. Section 6 of Schedule 1 to the Equality Act 2010 states:

“Cancer, HIV infection and multiple sclerosis are each a disability”.

For all other illnesses—whether they involve sensory impairments, fluctuating conditions like rheumatoid arthritis, or mental health disorders—the assessor evaluates the claimant’s ability to safely, repeatedly, and reliably complete specific daily activities.

The PIP Components and 2026/27 Rates

If a claimant’s illness meets the functional threshold, the DWP awards PIP based on two distinct components.  Claimants can receive either or both components, depending on their specific needs, at either a standard or enhanced rate.

1. Daily Living Component: This element applies if the claimant requires support with everyday tasks, such as preparing food, washing, managing medication, or communicating.
2. Mobility Component: This element applies if the claimant requires help with navigating and moving around.

For the 2026/27 tax year, the government has set the weekly PIP rates as follows:

• Daily Living (Standard): £76.70 per week.
• Daily Living (Enhanced): £114.60 per week.
• Mobility (Standard): £30.30 per week.
• Mobility (Enhanced): £80.00 per week.

The Scottish Alternative: Adult Disability Payment (ADP)

If your client resides in Scotland, they no longer apply for PIP. The Scottish Government replaced PIP with the Adult Disability Payment (ADP).

Administered by Social Security Scotland, ADP utilises essentially the same functional eligibility criteria and descriptors as PIP.  Furthermore, ADP shares the exact same two-component structure (Daily Living and Mobility) as the rest of the UK.  For example, entitlement to the mobility component of ADP triggers similar broader statutory recognitions, such as defining a “disabled person” for specific capital allowances on hire cars.

Tax Interaction: PIP and the 2026/27 Personal Allowance

A critical point for tax advisors is how PIP interacts with a client’s broader tax profile. PIP and ADP are entirely tax-free benefits. They do not count towards the client’s taxable income.

For the 2026/27 tax year, the UK Personal Allowance remains frozen at £12,570.  Because PIP is tax-exempt, a claimant earning £12,570 from employment and receiving £5,959.20 a year in Enhanced Daily Living PIP will not pay any income tax, as their taxable income exactly matches the £12,570 Personal Allowance threshold.

Summary Table: PIP and ADP 2026/27

For completeness, practitioners advising clients on applying for PIP or ADP should instruct them to gather robust medical evidence and daily care diaries detailing the exact functional impact of their condition, as DWP assessors prioritise practical limitations over mere medical diagnoses.
