Borderline Personality Disorder (BPD), also known as Emotionally Unstable Personality Disorder (EUPD), can be severely disabling. The intense emotional instability, self-harm urges, dissociation, relationship difficulties, and impulsive behaviour affect almost every PIP activity. Yet many people with BPD are refused because assessors don't understand the condition or dismiss it as "just a personality issue."
Which PIP Activities Does BPD Affect?
Engaging with Other People (Activity 9) - This is often the highest-scoring activity. BPD causes intense fear of abandonment, unstable relationships, difficulty reading social cues, and overwhelming emotional reactions to social situations. If you need support, prompting, or someone with you to engage with others, this scores 2-8 points.
Preparing Food (Activity 1) - Emotional dysregulation means you may go days without eating during a crisis. Dissociative episodes make handling knives and hot surfaces dangerous. Self-harm urges around sharp objects in the kitchen are a genuine safety risk. If someone needs to supervise you around kitchen hazards, this scores.
Managing Therapy (Activity 3) - BPD typically requires intensive therapy: DBT (Dialectical Behaviour Therapy), MBT (Mentalisation-Based Therapy), schema therapy, plus medication (mood stabilisers, antidepressants, antipsychotics). Weekly therapy sessions, daily skills practice, crisis planning, and medication management add up to significant weekly time.
Washing and Bathing (Activity 4) - During depressive episodes or crises, personal hygiene deteriorates dramatically. Dissociation in the shower is a falls risk. Self-harm wounds may need careful wound management during washing.
Making Budgeting Decisions (Activity 10) - Impulsive spending during emotional crises is a core BPD symptom. If you cannot manage your money without someone else's help, this scores 2-6 points.
Planning and Following Journeys (Activity 11) - Dissociative episodes can mean losing awareness of where you are. Emotional overwhelm in busy environments. Fear of being alone in unfamiliar places.
The Self-Harm Question
PIP specifically considers whether you can do activities safely. If your BPD means you are at risk of self-harm when left alone with sharp objects (kitchen), medication (therapy management), or in certain situations (bathing), this is directly relevant. You don't need to be actively self-harming - the risk is enough.
Describe it honestly: "I cannot be left unsupervised in the kitchen because I have a history of self-harm using kitchen knives. My partner removes sharp objects before leaving the house. Without this supervision, I am not safe to prepare food."
Evidence That Strengthens Your Claim
- Psychiatrist letters confirming diagnosis and severity
- CPN (Community Psychiatric Nurse) reports
- DBT or therapy records showing attendance and engagement
- Crisis team records and A&E attendances
- CPA (Care Programme Approach) documents
- Risk assessments from mental health services
- Partner or carer statement
Common Reasons BPD Claims Are Refused
"Presented well at assessment" - People with BPD often present well in structured, time-limited situations. A 45-minute assessment doesn't capture what happens when you're alone at 2am in crisis. If this happens, challenge it: "Presenting well during a brief assessment does not reflect my daily functioning. My condition fluctuates hourly and I experience multiple crises per week."
"Condition is not permanent" - Some assessors believe BPD is "curable." While people can learn to manage symptoms, BPD is a long-term condition. Get your psychiatrist to confirm it is ongoing and significantly impacts daily functioning.
