Does fibromyalgia qualify?
Yes. Fibromyalgia is a recognised chronic condition under the 2016 ACR criteria, supported by NICE guideline NG193, and assessors are specifically trained on it in the DWP PIP Assessment Guide. The test, as always, is functional impact across the 12 activities, not the diagnosis itself.
The fluctuating-conditions rule
This is the most important rule for fibromyalgia claims. Under Regulation 7 of the PIP Regulations, where your ability to do an activity varies, a descriptor applies if it applies on more than 50% of days over a 12-month period.
So you do not need to be incapable every day. If you can shower 2 days a week and cannot shower 5 days a week, the higher (more disabled) descriptor applies. Spell this out in the form.
The four reliability limbs
Under Regulation 4(2A), a task only counts as one you can do if you can do it against all four limbs. Fibromyalgia commonly fails on each:
- Safely. Fibro fog and grip failure at the hob mean cooking carries a real risk of harm.
- To an acceptable standard. Showering while managing pain flares leaves large areas unwashed.
- Repeatedly. A task done once on a good day cannot be done again on the 5 bad days that follow.
- In a reasonable time. Dressing at the DWP threshold is no more than twice the time a non-disabled person would take. Fibro flares blow past that easily.
Which descriptors apply
- Mobility 2, Moving around. Standing and walking distance limited by pain and fatigue. Score depends on the distance you can reliably walk, <200m for 4pts, <50m for 8pts, <20m for 12pts.
- Daily Living 1, Preparing food. Cannot stand long enough, cannot grip pans on bad days, fibro fog leading to safety issues, 2 to 8 points.
- Daily Living 4, Washing and bathing. Cannot get in/out of bath, needs grab rails, supervision on bad days, 2 to 8 points.
- Daily Living 6, Dressing. Pain limits putting on tops, bras, socks; needs aids or help, 2 to 8 points.
- Daily Living 3, Managing therapy / monitoring health. Complex medication regimens, need for prompts, 1 to 8 points.
- Mobility 1, Planning and following a journey. Fibro fog and panic on bad days, 4 to 12 points.
Fibro fog and cognitive descriptors
Fibro fog (cognitive dysfunction) is part of fibromyalgia and recognised in the 2016 ACR criteria. On fog days it can score on:
- DL 9, Engaging with people. Cannot follow conversation, cannot retain information.
- DL 7, Communicating verbally. Word-finding failure, processing delay.
- DL 10, Budgeting. Cannot follow numbers, missed bills.
- Mob 1, Planning a journey. Cannot plan or follow under cognitive load.
Evidence to send
- Rheumatology diagnosis letter (or GP diagnosis letter referencing the 2016 ACR criteria).
- GP summary printout showing fibromyalgia as a coded condition.
- Medication list, pregabalin, gabapentin, amitriptyline, duloxetine, opioids.
- 4–8 week symptom diary with pain, fatigue, sleep and function scores.
- Any OT or physio report, particularly aids and adaptations recommended.
- Letters from any pain clinic or fatigue management programme.
- A partner/family statement describing daily life and the pattern.
At the assessment
Common assessor traps with fibro:
- "You drove here, so mobility is fine." → "It was a bad day, I drove because I had no choice. I am in bed tomorrow."
- "You sat for 45 minutes" → "I have shifted position 15 times, my legs are numb, I will pay for this for 2 days."
- "You smiled" → "I have spent 20 years masking pain in public. The mask is not the evidence."
Bring the diary. Reference the 50% rule. Bring someone who can describe the recovery cost of the trip.
If you are refused
Fibromyalgia claims are commonly refused or under-awarded because assessors discount pain that has no visible sign. At MR, attach the diary and rewrite each disputed descriptor under the 50% rule. If MR fails, appeal, the tribunal panel includes a doctor who understands fluctuating pain. Full appeal process in our complete PIP guide.
The four-point rule (scrapped)
You may have read about a four-point rule starting in November 2026. It was removed from the bill in July 2025 and never became law. PIP rules are unchanged while the Timms Review runs (expected to report around autumn 2026). Evidence in descriptor and reliability language remains what decides awards.

Frequently asked questions
Can you get PIP for fibromyalgia?
Yes. Fibromyalgia is a recognised long-term condition that affects daily living and mobility. DWP guidance for assessors specifically addresses fluctuating conditions like fibro. Awards are common where pain, fatigue and fibro fog are well evidenced.
Do I need an NHS fibromyalgia diagnosis?
Strongly recommended. A diagnosis from a GP or rheumatologist using the 2016 ACR criteria, and a note from your GP confirming the diagnosis is on your medical record, is the foundation of the claim. See our guide on fibromyalgia diagnosis in the UK.
How do I evidence a fluctuating condition?
Use the 50% rule under Regulation 7: if a descriptor applies on more than 50% of days over a 12-month period, it counts as applying. A symptom diary across 4–8 weeks showing good and bad days is the strongest evidence of the pattern.
Which descriptors does fibromyalgia score on?
Most commonly: preparing food (DL 1), washing and bathing (DL 4), dressing (DL 6), moving around (Mob 2), planning a journey (Mob 1 on fibro-fog days), and managing therapy/medication (DL 3).
Does fibro fog count?
Yes. Fibro fog is recognised as a symptom of fibromyalgia and affects cognitive descriptors, particularly engaging with people (DL 9), communicating (DL 7), budgeting (DL 10), and following a journey (Mob 1).
