CF411 form explained: what it is, who needs it, and how to use it
If you’ve found gaps in your National Insurance (NI) record between 1978 and 2010, you may need to apply for Home Responsibilities Protection (HRP). One of the core application routes for HRP is CF411. This page explains what CF411 is, when you need it, and how to use it without delays.
Start with the main overview first: Home Responsibilities Protection (HRP): complete guide (1978–2010)
What is CF411?
CF411 is the application route used to apply for missing HRP years (and, in some cases, to request an HRP transfer where Child Benefit was in a partner’s name). If HRP is missing, correcting it can change the State Pension outcome.
Who might need CF411?
You may need CF411 (or the HRP application route) if one or more applies:
- You were awarded Child Benefit for a child under 16 during 1978–2010 but HRP is not showing for some years (especially if your claim started before May 2000).
- You’re applying on a partner transfer basis because Child Benefit was in the other partner’s name while you were the main carer.
- You’re applying via a caring route and need to provide a clear evidence chain for the relevant years.
CF411 vs CF411A (do not mix these up)
CF411 relates to HRP (1978–2010). CF411A is different — it relates to National Insurance credits from 6 April 2010 onwards and other related credit routes. Use this short guide to choose the right form: CF411 vs CF411A: which form do I need?
How do I get CF411?
- Online (recommended): use the GOV.UK HRP application route (fastest for most people).
- Postal route: complete the form online and print it, then post it with copies of your evidence.

What you’ll need to complete the application
- Your NI number and basic identity details.
- The exact tax years (6 April–5 April) you’re claiming for (use a one-page annex).
- Evidence for those years (Child Benefit letters/bank references, caring evidence, and ‘identity/address bridges’ if details changed).

Common mistakes that slow claims down
- Not specifying the exact tax years you’re claiming (HRP is year-by-year).
- Sending evidence without a clear annex or without labelling documents by year.
- Not bridging name/address changes (decision-makers can’t follow the identity chain).
- Using the wrong route (CF411 vs CF411A) for the period you’re trying to fix.
- Posting original documents instead of copies.
