PIP Mandatory Reconsideration in the United Kingdom

What is this right?
About 700,000 Mandatory Reconsiderations are filed each year for Personal Independence Payment. Only one in five succeeds at MR stage. But of those who push on to the First-tier Tribunal, around 58% win (HMCTS Tribunals Statistics Quarterly, Oct-Dec 2025) — and you cannot file a tribunal appeal until MR has been decided. MR is the gate.
The single biggest reason claimants lose at MR isn't that DWP is right — it's that the MR letter doesn't engage with the right legal test:
- Regulation 4(2A) of the PIP Regulations 2013 requires DWP to ask whether you can carry out an activity safely, to an acceptable standard, repeatedly, and within a reasonable time period. If you can only do something on a good day, that doesn't count.
- Regulation 7(1) requires DWP to score you on the descriptor that applies on more than 50% of the days over the assessment period — not your best day.
- The reliability and variability tests together are why most refused PIP claims should have been awarded. A well-built MR letter forces DWP to apply them.
When does it apply?
- You received a PIP decision letter from DWP refusing your claim or awarding fewer points than expected.
- The decision is dated within the last 1 calendar month (reg.3 of the D&A Regs 1999). Up to 13 months late is acceptable on 'special circumstances' grounds under reg.5.
- You have not yet asked for MR on this decision. You can only ask once per decision.
- You cannot appeal to the First-tier Tribunal until MR is decided — that's why MR is mandatory, not optional.
What to Do If Your PIP Decision Is Wrong
The clock starts on the date printed on the decision letter, not the date you received it. Don't waste a single day.
- Send the request in writing to the address printed on your decision letter, or to Freepost DWP PIP 1 (no postcode, no stamp). The Wolverhampton WV99 1AH address some people see online is for new PIP claims, not MR — don't use it.
- Call 0800 121 4433 (textphone 0800 121 4493), Mon-Fri 9am-5pm, to register the MR by phone. You still need to follow up with a written letter giving your reasons.
- Build the letter descriptor by descriptor. For each daily-living and mobility descriptor where DWP scored you wrong, explain (1) what activity DWP awarded, (2) which descriptor you say applies, (3) why — using the reg.4(2A) reliability test and the reg.7 variability test.
- Attach medical evidence with the MR letter — GP letter, consultant letter, OT report, hospital discharge notes, prescription list. DWP overturns far more decisions when fresh evidence comes in at MR than when it sees the same evidence twice.
- MR decisions typically take 6 to 12 weeks. You'll get a Mandatory Reconsideration Notice in the post.
- If MR fails, you have 1 calendar month from the MR Notice to lodge an SSCS1 appeal with HMCTS. About 58% of tribunal appeals are decided in the claimant's favour.
What should you NOT do?
- Don't miss the 1-month deadline. Late MR is possible but discretionary — every day you delay weakens the application.
- Don't repeat what was in the original application. DWP has already seen and rejected that. An MR letter that just rephrases the original ARM2 form rarely wins. Engage with the decision letter line by line.
- Don't accept the Health Care Professional's assessment as final. The assessor's report is opinion evidence, not a finding of fact. DWP and the tribunal are entitled to disagree with it. Many do.
- Don't be put off by the WCAG / FAS provider switch in September 2024. The new assessors (Maximus, Capita, Ingeus, Serco — regional) work to the same statutory test. The descriptor-mapping doesn't change.
- Don't give up at MR. Roughly two-thirds of people who go to tribunal win. The cost of the tribunal is zero — fees were quashed by the Supreme Court in R (UNISON) v Lord Chancellor [2017] UKSC 51.
