PIP Mandatory Reconsideration Unsuccessful: What Next and How to Appeal

The Letter That Changes Everything

When your PIP Mandatory Reconsideration is unsuccessful, the DWP sends you a Mandatory Reconsideration Notice (MRN). This letter confirms that the DWP has looked at the decision again and is not changing it — or, sometimes, that they have changed it slightly but not by as much as you hoped.

The MRN is not the end of the road. It is the starting point for an independent tribunal appeal.

DWP statistics show that only about 27% of Mandatory Reconsiderations result in an improved award. But 67% of PIP appeals that reach a tribunal hearing are won by the claimant, according to MoJ Tribunal Statistics (April–June 2026). In other words, the odds improve substantially once you move from the DWP's internal review to an independent panel.

Your One-Month Deadline

From the date printed on the Mandatory Reconsideration Notice, you have one calendar month to lodge an appeal with HMCTS. This is a strict statutory deadline under Rule 22(2)(d)(i) of the Tribunal Procedure Rules 2008.

The one-month clock starts from the date on the MRN letter — not the date you received it. If the MRN is dated 7 November and you do not receive it until 12 November, you have still lost five days. Note the date on the letter the moment it arrives and mark your calendar.

If the deadline falls on a weekend or public holiday, it extends to the next working day under Rule 12.

If You Miss the Deadline

Missing the one-month window does not necessarily mean your chance is gone. You can apply for a late appeal at any time up to 13 months from the date of the MRN — but you must give good reasons for the delay (serious illness, bereavement, communication failure, or other exceptional circumstances).

The decision to accept or reject a late appeal rests with a First-tier Tribunal Judge, not the DWP. The judge will consider whether you had good cause for the delay and whether it is in the interests of justice to extend time. Providing reasons does not guarantee the extension will be granted.

If you are approaching the deadline and are not ready to submit a detailed case, lodge a basic appeal now and build on it later — see below.

How to Lodge Your Appeal

You have two options:

Online: Use the GOV.UK "Appeal a benefit decision" service. You get an instant confirmation email and a tracking reference.

Paper: Complete the SSCS1 form and post it to HMCTS Benefit Appeals, PO Box 12626, Harlow, CM20 9QF. Use signed-for delivery and keep proof of postage.

The appeal needs five things to be valid:

1. Your name, address, date of birth, and National Insurance number
2. The name and contact details of any representative
3. A statement of why you believe the decision is wrong (grounds of appeal)
4. A copy of the Mandatory Reconsideration Notice
5. Your signature (or your appointee's)

Lodge First, Build Later

If the deadline is close and you have not had time to prepare a full case, submit a basic appeal with brief grounds — something like: "I believe the decision is wrong because the assessment did not accurately reflect how my conditions affect my daily living and mobility activities. I will submit a detailed written submission." This is valid. It meets the legal requirements. You can then take your time to write a proper written submission, gather medical evidence, and organise your case before the hearing.

The tribunal hearing typically takes place several months after the appeal is lodged — MoJ statistics report a mean wait of 37 weeks from submission to disposal for SSCS cases overall — so you have time to prepare once the appeal is safely registered.

What Happens After You Lodge

Once HMCTS processes your appeal, they serve notice on the DWP. The DWP then compiles a response bundle — typically containing your PIP1 claim form, PIP2 questionnaire, the PA4 assessment report, all medical evidence they hold, the original decision notice, and the MRN. This bundle is sent to you and to the tribunal.

At this point, 17% of initial appeals lapse because the DWP revises the decision in your favour before the hearing. If the DWP does not change its position, the appeal proceeds to a hearing before an independent panel of three: a judge, a medical member, and a disability member.
