I nodded along to all of this for years without really knowing what I actually had. DC, DB, SIPP, PCLS, annual allowance — it's a wall of initials, and most explanations start halfway up it. So let's start at the bottom.
The one idea that makes pensions click
Strip away the names, and a pension is a tax deal. You put money in and the government adds tax relief on top. It grows with no tax on the way. You can't touch it until a set age (currently 55, rising to 57 from April 2028). And when you do take it, the first 25% is tax-free and the rest is taxed as income.
That's the trade at the heart of every pension: a tax boost and tax-free growth now, in exchange for locking the money away and paying some income tax on the way out. Everything below is a variation on that one deal.
The tax relief, in real numbers
Relief comes at your income tax rate — so a £100 contribution effectively costs:
- £80 for a basic-rate (20%) taxpayer
- £60 for a higher-rate (40%) taxpayer
- £55 for an additional-rate (45%) taxpayer
Basic-rate relief is usually added automatically; higher and additional-rate taxpayers claim the extra through Self Assessment. There's a ceiling — the annual allowance — of £60,000 a year for most people (less for very high earners; more below).
Go deeper: the annual allowance rules that catch people out Advanced
The £60,000 headline hides three rules that trip up higher earners and anyone already drawing a pension:
- The taper. Once your adjusted income tops £260,000 (and threshold income tops £200,000), the allowance drops by £1 for every £2 over — down to a floor of £10,000 (MoneyHelper).
- Carry forward. If you didn't use your full allowance in the last three tax years, you can often carry the unused part forward and pay in more than £60,000 this year — provided you were a pension scheme member for those years. The carry forward guide works through it.
- The MPAA. The moment you flexibly take taxable cash from a DC pension, your annual allowance for future DC contributions collapses to £10,000 — permanently. A genuine trap if you dip into a pension early and carry on working.
For higher earners, salary sacrifice is usually the first lever to pull before any of this starts to bite.
The UK pension types, one by one
🏢 Workplace pension (defined contribution, "DC")
The most common private pension in the UK. Your employer takes contributions from your pay and adds their own; the money is invested in your name and grows or falls with markets — you carry the investment risk, and the final pot depends on how those investments do. Under auto-enrolment the minimum is 8% of qualifying earnings — at least 3% from your employer and 5% from you. The employer's share is the headline: it's money you only receive by paying in enough to trigger the match.
📈 SIPP (Self-Invested Personal Pension)
A DC pension you run yourself. Same tax deal, but instead of your employer's default fund you choose the investments — funds, shares, ETFs and more. Popular with the self-employed (who have no workplace scheme) and anyone who wants more control. A SIPP and a workplace DC pension are the same species — a pot of your money invested for retirement — just with different amounts of DIY. If you're weighing a SIPP against an ISA, our ISA vs SIPP guide walks through the trade-off.
🏛️ Defined benefit ("DB" — final salary or career average)
A completely different animal. A DB pension doesn't hand you a pot; it promises a guaranteed income for life, based on your salary and years of service. Your employer carries all the investment risk. It's common in the NHS, teaching, the civil service, the armed forces and older private schemes — and it's often called the gold standard, because that guaranteed, usually inflation-linked income is extraordinarily valuable and very hard to replicate.
👤 Personal pension
A simpler cousin of the SIPP: a personal DC pension where a provider runs a ready-made investment choice for you, rather than you picking everything yourself. Same tax treatment, less DIY. A reasonable middle ground if you want a private pension without managing it.
🏠 Lifetime ISA (LISA)
Not technically a pension — but it's used as one, so it earns its place here. You get a 25% government bonus on up to £4,000 a year (up to £1,000 free annually). It can be used for a first home, or for retirement from age 60. The catch: withdraw it early for anything other than a first home or age 60 and you pay a penalty that claws back the bonus and a little more. So the "first home versus retirement" distinction really matters with a LISA.
🇬🇧 The State Pension
The foundation the rest sits on. The full new State Pension for 2026/27 is £241.30 a week — about £12,548 a year — from State Pension age, which is 67 for most people now (it's rising from 66 to 67 between April 2026 and April 2028). You generally need 35 qualifying National Insurance years for the full amount, and at least 10 to get anything (gov.uk). Modest on its own, but as a base it meaningfully reduces what your other pensions have to cover.
The rules that shape almost all of them
- Access age. Currently 55, rising to 57 from 6 April 2028. You can't draw a DC pension or SIPP before then without a penalty.
- The 25% tax-free part. Up to 25% can be taken tax-free (the Pension Commencement Lump Sum); the rest is taxed as income.
- The annual allowance. £60,000 a year for most people. Very high earners (adjusted income over £260,000) have it tapered down — potentially to as little as £10,000.
- The employer match. On a workplace pension, the employer's contribution only lands if you pay in enough to trigger it — which is why people tend to look at the match before anything else.
Go deeper: the cap on tax-free cash Advanced
The “25% tax-free” isn't unlimited. Since the lifetime allowance was abolished, tax-free lump sums are capped by the Lump Sum Allowance of £268,275 across all your pensions combined (2026/27). For most people that's far more than they'll ever reach — but for larger pots it's the ceiling that matters, and some older pensions carry protected higher amounts worth checking before you touch anything.
So which is which, in a line each
- Workplace DC — your default pension, with free employer money attached.
- SIPP — the same idea, but you pick the investments (and the usual route for the self-employed).
- Defined benefit — a guaranteed income for life. Rare, valuable, don't touch without advice.
- Personal pension — a managed private pension, less hands-on than a SIPP.
- LISA — a 25% top-up for a first home or retirement from 60.
- State Pension — the flat-rate foundation from 67.
Which combination fits depends on your job, your tax rate, your timeline and whether you have a DB scheme — and for anything major, it's worth talking it through with a qualified adviser.

The hard part of pensions is that they're scattered — an old workplace pot here, a SIPP there, a DB scheme you half-forgot, the State Pension somewhere in the future. WealthR pulls workplace DC pensions, SIPPs, defined benefit schemes, LISAs and the State Pension into one retirement picture, so you can see what they'll actually pay and when. Free to try, no bank linking — and Pro adds a household pension-efficiency optimiser (which partner should make the next contribution) and the Tax Year Optimiser.
