What Happens to My Pension When I Change Jobs in the UK?

Changing jobs is one of those life events that generates a long list of things to sort out — notice periods, references, new contracts, new routines. Your pension tends to end up at the bottom of that list, and it often stays there indefinitely. A friend of mine who has worked for four different employers in ten years has three different workplace pensions sitting with three different providers. She has no idea how much is in each one. This is extremely common and more costly than most people realise.

This is the practical guide to what actually happens to your pension when you change jobs, and what to do about it. Not financial advice — but the kind of clear explanation that makes the decision obvious once you have it.

What Actually Happens When You Leave

When you leave a job, your pension does not disappear. The money you and your employer contributed stays invested in the scheme. You stop receiving new contributions from your old employer, but the existing pot continues to grow (or fall) based on the underlying investments.

You have three main options: leave it where it is, transfer it to your new employer's scheme, or transfer it to a personal pension (SIPP) you manage yourself.

There is no automatic requirement to do anything. The pot sits there, invested, until you either move it or access it at retirement. The problem with leaving it and forgetting about it — which is what most people do — is that the pot may be sitting in a poor-performing default fund, charging higher-than-necessary fees, and becoming increasingly difficult to keep track of as jobs accumulate.

Option 1: Leave It Where It Is

This is the path of least resistance and it is sometimes the right one. If the old scheme has a good investment range, low charges, and you are not accumulating large numbers of old pots — leaving it invested and checking it occasionally is fine.

Where it becomes a problem is when the default fund your money sits in is not appropriate for your timeline or risk tolerance, when the charges are higher than a SIPP you could transfer to, or when you genuinely lose track of it. I think most people underestimate how easily pension pots get forgotten — address changes, provider changes, mergers. Tracking down a pension you opened fifteen years ago is genuinely difficult.

Option 2: Transfer to Your New Employer's Scheme

Many workplace pension schemes accept transfers in from previous pensions. The benefit is simplicity — everything is in one place, one login, one statement. If your new employer's scheme has good investment options and reasonable charges, consolidating there is sensible.

The process is usually straightforward: ask your new employer's pension provider for a transfer form, fill in the details of your old scheme, and they handle the transfer. It typically takes 4-8 weeks.

Check the charges on your new scheme before transferring. Some workplace defaults have higher ongoing charges than a SIPP — in which case the SIPP route is worth considering instead.

Option 3: Transfer to a Personal Pension (SIPP)

A Self-Invested Personal Pension gives you full control over where your money is invested. You can choose a low-cost global index fund, keep all your old pots in one place regardless of how many jobs you have had, and often pay lower annual charges than a workplace default.

Providers like Vanguard (0.15% per year), AJ Bell (0.25%), and Hargreaves Lansdown (0.45%, capped at £200/year for pensions) all accept pension transfers. The process is similar to a workplace transfer — the new provider handles most of it once you initiate.

My personal view — not financial advice — is that for people who have had multiple jobs and have several small pension pots scattered around, consolidating into a SIPP they actively manage is almost always better than leaving everything fragmented. The investment control, fee transparency, and single view of your retirement savings are genuine advantages. The one exception is defined benefit schemes — these have guaranteed benefits that are almost always worth keeping rather than transferring.

How to Find Lost Pensions

If you have pensions from previous jobs and cannot track them down, the government's Pension Tracing Service can help. Go to gov.uk/find-pension-contact-details and enter your old employer's name — it will provide contact details for the pension scheme. It does not hold your pension or have access to your balance, but it can tell you who to contact.

Once you have the contact details, the pension provider can confirm your membership and current value. From there you can decide whether to transfer or leave it.

What About the State Pension?

Changing jobs has no direct effect on your State Pension, which is based on National Insurance contributions rather than workplace pension membership. Each year you pay NI contributions (or receive credits) counts toward your State Pension record. Check your State Pension forecast at gov.uk/check-state-pension — it takes two minutes and shows exactly how many qualifying years you have and what your current State Pension entitlement is.
