The UK State Pension is one of the most valuable benefits in the country — up to £12,547.60/year in 2026/27 (£241.30 a week), increasing each year under the triple lock. Yet many people don't know how much they're entitled to or whether they have gaps in their National Insurance record that are reducing their eventual payout. Checking and filling gaps could be worth tens of thousands of pounds over your retirement.
How to Check Your State Pension Forecast
You can check your State Pension forecast online in minutes through the government's Check Your State Pension tool at gov.uk/check-state-pension. You'll need a Government Gateway account (which you can create in about 5 minutes). The forecast shows: your current estimated pension at State Pension age, the number of qualifying years on your record, any gaps, and what you can do to increase your entitlement. You can also request a paper statement (BR19 form) if you prefer.
- Visit gov.uk/check-state-pension
- Log in with Government Gateway account
- Shows current forecast, qualifying years, and gaps
- Also available via the HMRC app
- Paper form BR19 available if you don't have online access
Understanding Your NI Record
You need 35 qualifying years of National Insurance contributions to receive the full new State Pension (£241.30/week in 2026/27). Each qualifying year is roughly worth £241.30 ÷ 35 = £6.89/week or about £358/year in additional State Pension. You need at least 10 qualifying years to receive any State Pension at all. Qualifying years come from employment (where NI is deducted from salary), self-employment, or NI credits (from Child Benefit, Universal Credit, etc.).
- Full pension requires 35 qualifying years
- Each year is worth approximately £358/year in State Pension income (2026/27)
- Minimum 10 years needed to receive anything
- Current State Pension age: 66, rising gradually to 67 between May 2026 and March 2028
- Triple lock guarantee: increases by highest of inflation, earnings growth, or 2.5% each year
How to Fill NI Gaps
If you have gaps in your NI record (years where you didn't earn enough or claim NI credits), you may be able to fill them through voluntary Class 3 NI contributions. The cost to fill a gap: £956.80 per year (£18.40 a week, the 2026/27 Class 3 rate). The benefit: approximately £358/year in additional State Pension for life. With average life expectancy beyond State Pension age of 15–20 years, this typically represents an extraordinary return on investment. Critically: there's a deadline. The special extension that let people fill gaps back to 2006 ended on 5 April 2025, so you can now normally only pay for the last six tax years. The 2020/21 tax year can be paid for until 5 April 2027.
- Cost to fill a gap: £956.80/year (Class 3 contributions, 2026/27)
- Benefit: ~£358/year more State Pension for life
- Break-even: under 3 years into retirement
- Can normally fill gaps from the last 6 tax years (2020/21 onwards until 5 April 2027)
- Some gaps can be filled for free through NI credits (claim child benefit, UC)
NI Credits: Free Ways to Protect Your Record
You may be entitled to free NI credits that count as qualifying years without you having to pay anything. Claiming Child Benefit protects NI record while caring for children under 12. Being on Universal Credit includes NI credits. Sick pay or statutory maternity/paternity pay periods accrue credits. Being a carer for a disabled person may provide Carer's Credit. Many people miss these free credits — particularly parents who didn't claim Child Benefit. See our guide to National Insurance credits for the full list.
- Child Benefit: NI credits for each child under 12
- Universal Credit: credits included automatically
- Statutory Maternity/Paternity/Sick Pay: credits included
- Carer's Credit: 20+ hours of caring per week qualifies
- Check your NI record for gaps that should have credits
Is it worth paying voluntary NI contributions?
For most people, yes. The break-even point is under 3 years into retirement. If you expect to live more than 3 years beyond State Pension age (highly likely for most), filling gaps pays off significantly.
Can I check my NI record if I'm self-employed?
Yes. Since April 2024, self-employed people with profits above the Small Profits Threshold (£7,105 in 2026/27) get a qualifying year without paying Class 2, and those below it can pay Class 2 voluntarily (£3.65 a week). Check your record to make sure each year has been recorded correctly.
