Gathering Evidence for Disability Benefits

Different types of evidence serve different purposes in a disability benefit assessment:

• GP letters: A letter from your GP confirming your diagnosis, treatment, and functional impact is one of the most useful forms of evidence. Ask your GP to comment specifically on how your condition affects daily activities — not just what you have been diagnosed with.
• Specialist letters: Letters from consultants, psychiatrists, physiotherapists, occupational therapists, or community mental health teams carry significant weight, particularly where they describe observed functional limitations.
• Care records: Social care assessments, discharge summaries, care plans, and records of any support you receive all demonstrate that your needs have been formally assessed and recognised.
• Prescription records: A list of current medications, particularly where side effects (such as fatigue, dizziness, or cognitive effects) are relevant to your claim.
• Daily living diary: A written account of your typical week, describing specific difficulties — how long it takes to get dressed, whether you need help, whether you have had to cancel activities due to your condition.

Many GPs and specialists are willing to provide supporting letters for disability benefit claims, but you may need to be specific about what you need. When requesting a letter, ask your clinician to:

• Describe your diagnosis and how long you have had the condition
• Explain how the condition affects your ability to carry out daily activities — specifically things like washing, dressing, preparing food, managing medication, and travelling
• Comment on variability — if your condition fluctuates, ask them to note that you have good days and bad days and that bad days can be significantly more limiting
• Reference any relevant clinical observations, test results, or formal assessments they have carried out

Be aware that some GP practices charge for letters written for non-NHS purposes. Ask in advance about any fee. Some charities (such as Scope and Mind) can help you obtain supporting evidence or write to clinicians on your behalf.

Collecting evidence is only half the task — you need to present it effectively. Key tips:

• Submit with the claim form, not just at appeal. Many claimants wait until they are refused to gather evidence. Submitting strong evidence upfront can secure the right award at the first stage.
• Reference your evidence in the claim form. When answering questions about daily activities, explicitly refer to supporting documents: "See GP letter from Dr Smith dated 1 March 2025."
• Describe your worst days. Assessors consider your ability to perform activities reliably, safely, and repeatedly. If your condition is variable, describe your limitations on a bad day — which may be the majority of days.
• Use the correct language. For PIP, the assessment uses specific descriptors for each activity. Familiarise yourself with these and make sure your evidence and answers align with the relevant descriptors.
