You can get free PIP guidance from Citizens Advice, local welfare rights services and disability charities such as Scope. The official GOV.UK PIP pages explain the eligibility rules, application process and what evidence may help support your claim. An adviser may also help you describe how your condition affects daily living and mobility, or understand a mandatory reconsideration if your claim is refused. The DWP makes each decision using your circumstances and the available evidence; for a tribunal or complex legal issue, consider a law centre or solicitor regulated by the SRA.
