The NHSBSA Exemption Checking Service can write months after a pharmacy or dental claim. That delay is why people are shocked by a sudden pile of letters.
Responding the right way
- Find the reference at the top of the letter.
- Use the official Respond to your letter service.
- If unsure about ongoing entitlement, protect the next pickup with a PPC.
- If a PCN already arrived, follow our PCN challenge guide.
Do not mix with HMRC letters. Tax / Tax Credits mail can arrive around the same time — the reference and NHSBSA sender help you tell them apart.
Why early action matters
An enquiry is a chance to clarify entitlement before it becomes a fine. Keep a copy of your reply, attachments, and dates — useful if a PCN follows.
