Pensions in plain English

A pension is a long-term savings account with one superpower: the government adds free money to it. For a basic-rate taxpayer, every £80 you put in becomes £100 inside the pension. That's an instant 25% return before your money does anything.

And if your employer matches your contributions — which most do — you're getting paid to save. It's the closest thing to free money in personal finance. The catch? You can't touch it until you're 57 (rising to 58 in 2028). But for retirement savings, that restriction is the point.

So for every £158 that comes out of Sam's pay, the pension actually receives £253 — that's the employee contribution plus the employer match. The tax relief is built in (the pension contribution comes from gross pay, so you never pay tax on it in the first place).

Put differently: Sam “loses” £158/month from take-home pay, but gains £253/month in pension contributions. That's a 60% instant return. No investment in history has matched that consistently.

At current contribution rates, Sam's pension could grow to approximately £384,967 by age 65. Total contributions over that time: £124,980. The gap between the two numbers? That's compound growth doing its work.

Auto-enrolment explained. If you earn at least £10,000 a year from a UK job and you're aged 22 to State Pension age, your employer has to put you into a workplace pension automatically. You can opt out, but you lose the employer contribution if you do.

The “minimum 8%” figure you'll often see refers to contributions on a band of your qualifying earnings — currently between £6,240 and £50,270 a year, which is usually less than 8% of your actual salary. In practice, most workplaces contribute on a slightly different basis; the easiest way to know yours is to check your payslip or pension statement.

The problem: the minimum probably isn't going to be enough for a comfortable retirement. To live what most people would call a “decent” retirement — not luxury, just comfortable — you need roughly £43,100 a year (that's for a single person). The state pension gives you about £12,547 of that. The rest has to come from your own pension pot — and at minimum contributions, most people won't get there unless they start very young or earn well above average.

A commonly cited benchmark is that the total going in (employer plus employee) should be a percentage of your salary that's roughly half your age. It's a rule of thumb, not a personal target — the right number for you depends on when you started, what you already have, and when you want to stop working.

The average person has 11 jobs over their lifetime. Every one of those might come with a workplace pension. When you leave a job, that pension doesn't vanish — but it's very easy to lose track of it. And those old pots might be sitting in expensive funds, quietly getting eaten away by fees you don't even know you're paying.

Consolidating into a single pension is a decision with real trade-offs, not an automatic win. Before moving anything, it's worth checking:

• Any guaranteed benefits (Guaranteed Annuity Rates, protected tax-free cash, protected early retirement ages). Giving these up to consolidate is often a bad trade and can be irreversible.
• Defined benefit pensions — if any of your old pensions are DB (sometimes called “final salary”), consolidating them away is a regulated advice decision and legally requires a qualified adviser for pots over £30,000.
• Exit fees on the scheme you'd leave.
• Employer contributions — consolidating an active workplace pension means losing the ongoing employer top-up.

Done well, consolidation can simplify your retirement picture and reduce fees. Done badly, it can cost you more than you save. If you're thinking about it seriously and you have anything defined-benefit, anything with guarantees, or any pension worth more than £30,000, speak to an FCA-authorised adviser — you can find one at unbiased.co.uk or vouchedfor.co.uk.
