Pensions 101 — start here

Why pensions beat almost everything

A pension is just an investment account with three superpowers bolted on: tax relief on the way in (£100 invested costs a basic-rate taxpayer £80, a higher-rate taxpayer £60), employer money added on top in a workplace scheme, and decades of tax-free compounding inside. The trade is access — you can’t touch it until age 55, rising to 57 in 2028. For money you genuinely won’t need until then, nothing else comes close: £80 of take-home pay becomes £100 invested before it has earned a penny of return.

The system has a reputation for complexity it only half deserves. There are exactly three layers, and everything in this section is about one of them.

The three layers

1. The State Pension — around £12,000 a year from age 66–67, inflation-proofed for life, earned through your National Insurance record. Not enough to live well on, but a bedrock worth £300,000+ if you had to buy it — and cheap to top up if your record has gaps. The State Pension guide shows how to check your forecast in five minutes.
2. Workplace pensions — the auto-enrolment scheme your employer must put you in, with a legal minimum of 8% of qualifying earnings going in, at least 3% from the employer. The workplace pension guide covers the match, salary sacrifice, and the default-fund decision almost nobody reviews.
3. Private pensions (SIPPs) — a pension you open and control yourself, useful for the self-employed, for contributions beyond your workplace scheme, and for gathering up old pots. The SIPP guide explains who actually benefits and how to track down forgotten pensions.

What to do at different ages

• 20s: One job: don’t opt out. The 8% minimum plus compounding from age 22 does enormous work — £200 a month from 22 grows to roughly twice what the same contribution from 32 does. Check the default fund isn’t parked in something timid; at this age it should be nearly all equities.
• 30s–40s: Nudge the percentage up with every pay rise — from 8% toward 12–15% of full salary — before lifestyle absorbs the raise. Higher-rate taxpayers: make sure you’re actually receiving 40% relief (the tax relief guide covers the refund many forget to claim). Round up stray pots from old jobs before they multiply.
• 50s: The allowances become interesting: up to £60,000 a year can go in, and carry-forward can sweep up unused allowance from the previous three years — powerful in peak-earning or windfall years. This is also the decade to consolidate old pensions carefully (some have valuable guarantees — never rush a transfer) and to start reading about drawdown before you need it.
• 60s and beyond: The decision flips from accumulation to income: how much to withdraw, in what order, and how to avoid selling in crashes. Sequence risk, the 25% tax-free lump sum, and tax-efficient withdrawal ordering are the drawdown guide’s subject — the decisions here determine whether the money lasts.

What to do at different incomes

• Lower earners: Auto-enrolment still pays — the employer 3% and tax relief are a raise you claim by doing nothing. Check your NI record: qualifying years for the State Pension come from earnings above just £6,500 or so, and credits cover periods of caring or unemployment.
• Higher-rate taxpayers: Pensions are at their most lucrative — 40% relief in, usually 20% or less on the way out, plus 25% tax-free. Salary sacrifice adds NI savings on top. This is the income band where pension-first (after the ISA emergency buffer) is usually right.
• £100,000+ earners: Pension contributions can rescue the 60% effective tax band between £100,000 and £125,140, but watch the tapered annual allowance further up. Rules here genuinely warrant the detail in the tax relief guide.

How much is enough?

A rough compass, not a rule: aim for a pot of around 25 times the annual income you want it to provide on top of the State Pension. Want £15,000 a year from your pot? Target ~£375,000. A common savings heuristic is to contribute (as a % of salary, including employer money) half your age when you start — 12% starting at 24, 20% starting at 40. Both numbers are blunt, which is why running your own is better: the Financial Planner does exactly that.

The single most expensive pension mistake is not fund choice, fees, or timing — it’s contributing too little, too late, or opting out entirely. Every guide in this section is ultimately about making it easier to put more in earlier.

The guides in this section

• Workplace pensions — auto-enrolment, why the employer match is unbeatable, what salary sacrifice adds, and the default fund most people never look at.
• SIPPs and consolidating old pensions — what a SIPP actually is, who benefits, how to find forgotten pots, and the transfers you should never rush.
• Pension tax relief and the allowances that cap it — how relief really works, the £60,000 annual allowance and carry forward, the taper and MPAA traps, and the refund higher-rate taxpayers forget.
• State Pension and your National Insurance record — qualifying years, the five-minute forecast check, and when buying voluntary NI years is the best deal in UK finance.
• Retirement drawdown — turning a pot into an income: sequence risk, safe withdrawal rates, and the ordering that keeps the taxman’s share small.
• Pensions and inheritance tax — the April 2027 change that brings unused pots into the estate for IHT, who it actually affects, and how to rethink “spend the pension last”.
