How to Claim Guardian's Allowance Without Losing Original Certificates in the Post

If you are worried about posting original birth and death certificates to HMRC for a Guardian's Allowance claim, you are not being overcautious — these are irreplaceable legal documents, and HMRC's own guidance gives you a PO Box address and the instruction "send originals" with almost no advice on how to protect them in transit. The practical answer is: use Royal Mail Special Delivery Guaranteed by 1pm, photograph or photocopy every document before posting, and record the serial numbers and tracking reference. HMRC's BG1 notes say it returns certificates with its acknowledgement after receiving the claim.

None of this is complicated. But if nobody tells you to do it, you post the certificates in an ordinary envelope and then spend weeks unable to sleep, wondering whether the one document proving your grandchild's parent has died is sitting in a sorting office somewhere between your kitchen table and Newcastle.

Why HMRC Requires Originals

The BG1 notes require original certificates and explicitly say photocopies are not accepted. They list a full birth certificate for each child showing the parents' names, a death certificate for each parent if applicable, and the child's adoption certificate if applicable.

The BG1 notes do not give a further reason for requiring originals; follow the document list on the current form and notes.

Step-by-Step Certificate Protection

Before You Post

1. Photocopy or photograph every document — front and back. Store the copies in a separate location from where you keep the originals. These copies have no legal standing with HMRC, but they prove what you sent and give you the serial numbers if anything goes missing.

2. Record the serial numbers of each certificate. Birth and death certificates issued in England and Wales carry a GRO reference number. Scottish certificates have a registration district and entry number. Northern Ireland certificates have their own numbering system. Write these down separately.

3. Compile a contents list — a plain sheet of paper listing every document you are including in the envelope, with serial numbers and descriptions. Keep a copy for yourself. This list serves two purposes: it forces you to confirm what you are sending, and it gives HMRC's processing team a manifest to check against when they open the package.

How to Post

Use Royal Mail Special Delivery Guaranteed by 1pm. This provides:

• A tracking number you can check online
• Proof of posting
• A signature on delivery
• Compensation cover up to £750, subject to Royal Mail's terms

For an item up to 100g, the current price is £10.35 at a Post Office or £9.85 online. That is about three days of Guardian's Allowance at £22.95 per week.

Post to the current BG1 address: HM Revenue and Customs, Guardian's Allowance Unit, Child Benefit Office, PO Box 4, Newcastle upon Tyne, NE88 1AE.

Getting Your Certificates Back

HMRC's current BG1 notes say that when it receives your claim, it will send an acknowledgement with a contact name and phone number and return any certificates you sent with that acknowledgement. The notes do not promise tracked return.

If the acknowledgement arrives without your certificates, contact the Unit using the details in the acknowledgement. Have your National Insurance number and the tracking reference from your outbound posting ready.

What to Do If Certificates Go Missing

If the worst happens:

• Check the Royal Mail tracking — Special Delivery items that show "delivered" but have not been acknowledged by HMRC may be sitting in an internal processing queue. Phone the helpline.
• Replacement certificates in England and Wales can be ordered from the General Register Office. A standard copy costs £12.50 and is sent 4 days after applying if you provide the GRO index reference; without one, a search costs an extra £3.50 and takes 15 working days. The priority service costs £38.50 and is sent the next working day if ordered by 4pm. Scotland and Northern Ireland have separate services and fees.
• Replacement birth certificates follow the same process. If the child was born abroad, the replacement process depends on the country of birth.
• Royal Mail Special Delivery includes compensation cover up to £750, subject to Royal Mail's terms.

Who This Is For

• Any relative about to submit a Guardian's Allowance claim who holds irreplaceable certificates and is anxious about posting them
• Carers who have already lost documents in the post to a government department and are determined not to repeat the experience
• The family member organising the claim on behalf of an elderly grandparent who needs a clear, repeatable process

Who This Is NOT For

• Anyone whose claim has already been processed and certificates returned — this guide covers the submission stage
• Carers looking for general Guardian's Allowance eligibility information — that is covered in the eligibility overview

The Broader Claim Preparation Problem

Certificate safety is one piece of a larger preparation challenge. The BG1 interactive PDF cannot be saved mid-completion. The surviving-parent circumstances are described briefly. Guardian's Allowance can be backdated for up to three months (£298.35 for 13 weeks at the 2026/27 rate), and the official guidance does not say a separate written request or specific wording is required.

The Guardian's Allowance Claim Guide addresses all of these together — including a printable certificate postal log for recording serial numbers, posting dates, tracking references, and return dates, alongside the pre-filling worksheet and exception decoder. The free checklist on the same page covers the basic eligibility check and document list.

Frequently Asked Questions

Can I take my certificates to an HMRC office instead of posting them?

HMRC does not process Guardian's Allowance claims at local offices. The Guardian's Allowance Unit in Newcastle handles all claims by post. There is no in-person submission option for BG1.

Will HMRC accept certified copies from a solicitor?

The BG1 notes require original certificates and explicitly say photocopies are not accepted. They do not list solicitor-certified copies as an alternative, so send the originals requested on the form.

How long does HMRC keep my certificates?

HMRC's BG1 notes say it sends the acknowledgement and any certificates with it after receiving your claim, then writes with its decision. GOV.UK does not publish a processing-time target. If the acknowledgement arrives without your documents, contact the Unit using the details in the acknowledgement.

What if I only have one copy of the death certificate and need it for other purposes?

Order a second copy before you post if you need one for other purposes. In England and Wales, a GRO copy costs £12.50 and is sent 4 days after applying if you provide the index reference; without it, a search costs an extra £3.50 and takes 15 working days. The £38.50 priority service is sent the next working day if ordered by 4pm. Scotland and Northern Ireland have separate services and fees.

Is Royal Mail Special Delivery really necessary?

Strictly, no — you can post by standard First Class letter. It has no tracking or signature, and compensation for loss or damage is capped at £20. For an item up to 100g, Special Delivery costs £10.35 at a Post Office (£9.85 online), compared with £1.80 for First Class; it includes full tracking, photo and signature on delivery, and cover up to £750. Given that you are posting original documents and a lost claim can delay a benefit worth £22.95 per week, tracked posting is a straightforward precaution.
