Changing jobs is exciting. But somewhere between handing in your notice and starting your new role, most people forget to ask one important question — what happens to the pension I’ve been building up?
The answer depends on what type of pension you have, how long you’ve been contributing, and what you decide to do next. Here’s a clear breakdown of everything that can happen and what your options actually are.
Your Pension Doesn’t Disappear
The first thing to understand is that your pension pot belongs to you, not your employer. When you leave a job, the money you’ve contributed stays yours. Your employer’s contributions also stay in the pot, as long as you’ve passed the vesting period — which for most workplace schemes is two years.
If you’ve been at a job for less than two years, it’s worth checking your scheme’s rules. Some employers will refund their contributions if you leave before the vesting period ends, though yours always stay.
What Happens to a Defined Contribution Pension
This is the most common type of workplace pension today. Both you and your employer put money in, it gets invested, and the pot grows over time.
When you leave, the pot just sits there with the pension provider. It keeps being invested according to whatever funds it’s currently in. You don’t have to do anything immediately — and in many cases, doing nothing is a completely reasonable short-term decision.
Your options are:
Leave it where it is. The money stays with your old employer’s scheme or provider and continues to grow. You’ll get annual statements and can access it from age 57 onwards (rising to 57 in 2028). The downside is that if you change jobs several times, you end up with multiple small pots scattered across different providers, which can get difficult to manage.
Transfer it to your new employer’s pension. Most workplace schemes accept transfers in. You’d contact your new pension provider, request a transfer, and the old pot moves across. This is often the tidiest option — one pot, one place, easier to track.
Transfer it to a personal pension. If you’d rather manage your own investments or want more control over where your money is invested, you can move it into a Self-Invested Personal Pension, known as a SIPP. Platforms like Vanguard, Hargreaves Lansdown, or AJ Bell are commonly used for this. Fees and fund choice vary significantly, so it’s worth comparing before you commit.
What Happens to a Defined Benefit Pension
Defined benefit pensions — sometimes called final salary schemes — work differently. Your retirement income is based on your salary and how many years you worked, not on a pot of invested money.
When you leave, you’re usually given a “deferred pension.” This means you’ve built up a right to a certain income in retirement, and that amount is preserved until you reach the scheme’s retirement age. It’s typically increased each year by inflation up to a certain cap.
Transferring a defined benefit pension is possible but comes with serious caveats. If the transfer value is above £30,000, you’re legally required to take regulated financial advice before moving it. The reason for this rule is that you’d be giving up a guaranteed income for life in exchange for a lump sum to invest yourself — that’s a significant trade-off, and it’s not right for most people.
Tracking Down Lost Pensions
If you’ve changed jobs a few times and aren’t sure where all your old pension pots are, you’re not alone. There’s an estimated £26 billion in unclaimed pension savings in the UK.
The government’s Pension Tracing Service is a free tool that helps you find contact details for old workplace schemes. You can access it at gov.uk/find-pension-contact-details. It doesn’t tell you your balance — you’d need to contact the scheme directly for that — but it gets you to the right door.
Combining Pension Pots — Is It Always a Good Idea
Consolidating pensions sounds tidy, but it’s not automatically the right move in every situation.
Before you transfer anything, check whether your old scheme has any guarantees attached to it. Some older pensions have guaranteed annuity rates built in — meaning they’ll give you a much better income in retirement than current market rates would offer. Transferring out of those can be an expensive mistake.
Also check the charges on both sides. Moving from a low-cost older pension into a newer one with higher annual fees could cost you money over the long run, even if it feels more convenient.
What About the State Pension
Changing jobs doesn’t affect your State Pension directly. The State Pension is built up through National Insurance contributions, not through your employer. As long as you keep working and paying NI — or get NI credits if you’re in certain situations — your State Pension entitlement keeps building up regardless of how many employers you have.

Auto-Enrolment in Your New Job
When you start a new job, your employer is legally required to automatically enrol you into a workplace pension if you’re aged between 22 and State Pension age and earning above £10,000 per year.
This usually happens within three months of starting. You’ll receive a letter confirming you’ve been enrolled, which scheme you’re in, and how much you and your employer will contribute. You can opt out if you choose, but doing so means giving up your employer’s contributions — which is effectively part of your salary.
The minimum contributions under auto-enrolment are 5% from you and 3% from your employer, based on qualifying earnings. Many employers offer more than the minimum, particularly at senior levels, so it’s always worth checking what’s on offer before you accept a job.
The Smartest Thing to Do When You Change Jobs
Give yourself a week or two after starting the new role, then sit down and make a list of every pension you have. Include the provider name, policy number, and approximate value if you know it.
Once you have that picture, it’s much easier to decide what to make sense to consolidate and what to leave alone. If the total value across your pensions is significant — say, above £50,000 — it’s worth speaking to a regulated financial adviser before making any transfer decisions. The cost of advice is usually far less than the cost of making the wrong move.
Your pension is likely to be one of the biggest financial assets you ever build. Changing jobs is a natural prompt to give it some proper attention.
