Retirement savings catch-up: a mid-career guide for UK workers

The Pensions UK (formerly PLSA) Retirement Living Standards put a 'moderate' retirement for a single person at about £31,700 a year (2025 figures), including the State Pension. Take an illustrative target pot of £600,000: at age 45 with £50,000 saved, you'd need to put in around £850-£900 per month (including tax relief and employer contributions) until age 68 to get there, assuming 5% annual growth after inflation. That's daunting but not impossible. Tax relief helps: a basic-rate taxpayer effectively gets a 25% boost from the government (a £100 contribution costs £80), and a higher-rate taxpayer can get a 66.7% boost (£100 costs £60) once the extra relief is claimed. The key is not to panic about the gap, but to make a structured plan.

Carry forward allows you to use unused annual pension allowance from the previous three tax years. The annual allowance is £60,000 in 2026/27, and it was also £60,000 in each of the three previous years (2023/24, 2024/25 and 2025/26). If you contributed little or nothing in those years, you may have significant unused allowance available. How it works: you can contribute up to £60,000 this year (2026/27) plus any unused allowance from 2023/24, 2024/25, and 2025/26. You must have been a member of a pension scheme in those years (any UK pension scheme counts, even if you didn't contribute). You must use the current year's allowance first, then the oldest year's unused allowance (2023/24), then 2024/25, then 2025/26. Example: you contributed £10,000 in 2023/24, £5,000 in 2024/25, and £15,000 in 2025/26. Unused allowances: £50,000 (2023/24), £55,000 (2024/25), £45,000 (2025/26). In 2026/27, you could contribute up to £60,000 (current year) + £150,000 (carried forward) = £210,000 in total without an annual allowance charge. That's a massive catch-up contribution. Bear in mind that your own contributions only get tax relief up to 100% of your UK earnings for the year, so large personal contributions need earnings to match (employer contributions aren't limited in this way). Carry forward is particularly powerful for self-employed people or those who've had variable income years.

If you're employed, your workplace pension is the most efficient catch-up vehicle. Auto-enrolment requires minimum contributions of 8% of qualifying earnings (5% from you, 3% from your employer). But you can contribute more, and many employers will match additional contributions up to a limit. Check your employer's matching policy: if they match up to 8% (your 5% + their 3% is the minimum), contributing 8% from you might get them to contribute 8% as well, which is 16% in total. Some employers match pound-for-pound up to a certain percentage. This is free money that dramatically accelerates catch-up. Salary sacrifice (if offered) makes contributions even more efficient: your contribution comes from pre-tax and pre-National Insurance income, saving you 8% or 2% NI (depending on your earnings) on top of tax relief. A £100 contribution via salary sacrifice costs a basic-rate taxpayer approximately £72 in take-home pay (£100 minus 20% tax minus 8% NI = £72). That's a 39% instant boost before investment growth. From 6 April 2029, only the first £2,000 a year of salary-sacrificed pension contributions will be free of NI. If you're over 40, consider increasing contributions by 1% of salary each year until you reach your maximum affordable level. Because of tax relief (and NI savings with salary sacrifice), a 1% increase reduces take-home pay by less than 1%. The gradual increase is barely noticeable but compounds significantly over 20+ years.

If your adjusted income exceeds £260,000 (2026/27), your annual allowance tapers down by £1 for every £2 over £260,000, to a minimum of £10,000. Adjusted income includes all taxable income plus employer pension contributions. This affects high earners who are also trying to catch up. Strategies: use carry forward from years when you had lower income (and therefore a full £60,000 allowance), consider contributing to a spouse's pension if they have unused allowance (transfers between spouses are not allowed, but you can gift money for them to contribute), and explore other tax-efficient investments (ISAs, VCTs, EIS) for retirement savings beyond your reduced pension allowance. The money purchase annual allowance (MPAA) is another consideration: if you've accessed your pension flexibly (taken more than the 25% tax-free lump sum), your annual allowance reduces to £10,000. This severely limits catch-up ability. If you're considering accessing your pension early but plan to continue working and contributing, understand this restriction first.

Pensions are the primary retirement vehicle, but ISAs play a crucial complementary role, especially for catch-up. The advantages: tax-free withdrawals (unlike pensions where 75% is taxable), no age restrictions on access (pensions can't be accessed until 55, rising to 57 in 2028), and flexibility (you can withdraw for emergencies without penalty). The disadvantage: no tax relief on contributions. For mid-career catch-up, a combined approach works best: maximise pension contributions to get tax relief and employer matching, then contribute to a Stocks & Shares ISA for additional retirement savings. The ISA allowance is £20,000 per year (2026/27). If you can afford to save more than your pension annual allowance (or tapered allowance), ISAs are the next best option. A common strategy: contribute enough to your pension to get full employer matching and higher-rate tax relief (if applicable), then max out your ISA, then contribute additional amounts to your pension up to the annual allowance. This balances immediate tax efficiency with long-term flexibility. For those within 10-15 years of retirement, consider a more conservative ISA investment strategy than your pension, as you have less time to recover from market downturns. Target-date funds or balanced portfolios may be more appropriate than 100% equities.

At age 45 with £50,000 saved, targeting £600,000 by age 68 requires saving approximately £850-£900 per month with 5% real growth. Break this down: workplace pension: £500/month (including employer contributions and tax relief). SIPP: £250/month. ISA: £150/month. That's £900 total. If that's unaffordable, start with what you can and increase annually. Calculate your required monthly contribution using a pension calculator, such as MoneyHelper's or our own pension calculator, and check your State Pension forecast on GOV.UK. Review annually: as your salary increases, increase contributions proportionally. Consider working slightly longer: each extra year of work and saving reduces the required pot size (because you have one less year of retirement to fund) and allows additional contributions. The psychological shift: view retirement savings not as a distant abstraction but as your most important financial goal. Automate contributions on payday. Reduce discretionary spending to free up catch-up funds. Remember that every £100 saved at age 45 could be worth about £307 at age 68 (5% growth): compounding still works in your favour, even starting late.
