The word "pension" covers several quite different things in the UK, and conflating them causes a lot of confusion. Broadly there are three pillars: the State Pension, workplace pensions, and personal pensions — and many people will have more than one.
The State Pension
Provided by the government and based on your National Insurance record rather than what you've saved, the State Pension is the foundation. It's the same mechanism for everyone who qualifies, and it's separate from — and in addition to — anything you build privately.
Workplace pensions
Arranged through your employer, usually via auto-enrolment, with contributions from you, your employer, and tax relief. Most modern workplace pensions are defined contribution — a pot built from contributions and investment growth. Older defined benefit schemes promise an income based on salary and service instead.
Personal pensions
Ones you set up yourself, independent of an employer — useful if you're self-employed, or want to save beyond a workplace scheme. These include standard personal pensions and self-invested personal pensions (SIPPs), which offer more control over how the money is invested.
The tax relief that makes pensions attractive
Across workplace and personal pensions, contributions generally attract tax relief, which is a large part of what makes pensions a tax-efficient way to save for later life. The rules and limits around contributions and relief are set by government and reviewed periodically, so check current allowances on gov.uk. For how a Lifetime ISA compares as a complementary option, see our LISA guide.
Keeping track of old pensions
Changing jobs several times can leave a trail of small workplace pensions scattered across providers. They don't disappear, but they're easy to lose track of. Keeping a simple record of which pensions you have, and reviewing them occasionally, stops money quietly going astray — the government's Pension Tracing Service can help find lost ones.
Frequently asked questions
How many pensions can you have?+
There's no limit on the number of pensions you can hold. Most people accumulate several over a working life — one from each employer, plus perhaps a personal pension. What's limited is how much you can contribute tax-efficiently each year across all of them (the annual allowance), not how many pots you own.
What's the difference between defined benefit and defined contribution pensions?+
A defined contribution (DC) pension builds a pot from contributions plus investment growth — what you get depends on how much went in and how the investments performed. A defined benefit (DB) pension promises a set income in retirement, usually based on your salary and years of service. DB schemes are increasingly rare outside the public sector.
Should I consolidate my old pensions?+
Sometimes — combining pots can make them easier to track and may reduce charges. But it isn't always right: some older schemes carry valuable guarantees you'd lose by transferring, particularly defined benefit ones. This is a decision worth taking advice on rather than doing on a whim.
What is a deferred pension?+
A deferred pension is simply one you're no longer paying into — typically from a previous employer. The money remains invested and stays yours; “deferred” just means dormant, not lost. You can usually claim it when you reach the scheme's retirement age.
Should I use an ISA or a pension?+
They do different jobs. Pensions get tax relief and often an employer contribution, but the money is locked away until a set age. ISAs are more flexible but don't get tax relief or employer top-ups. For many people, capturing an employer's pension match first is the priority. This is general information, not personal advice.
