How to Transfer a Pension to a SIPP and Combine Old Pots

If you have changed jobs a few times, you probably have several small pension pots scattered across different providers, each quietly charging its own fee. The case to transfer a pension to a SIPP is simple: one modern account, one set of low charges, and a fund choice you actually control. But a transfer is not always the right move, and a handful of old pensions carry guarantees that are worth far more than any fee saving. This guide walks through the process and the checks that stop a good idea becoming an expensive mistake.

A SIPP, or self-invested personal pension, is a defined contribution pension you run yourself, usually through a low-cost investment platform. Consolidating old pots into one is one of the most common reasons people open a SIPP, but the value depends entirely on what you are moving.

Before you transfer: the checks that matter most

The single most important step happens before any paperwork. For each old pension, ask the provider in writing whether the plan holds any of the following, because these are usually lost the moment you transfer out:

• A defined benefit (final salary) promise. This pays a guaranteed income for life. If the transfer value is more than £30,000 you are legally required to take regulated advice from an FCA-authorised adviser before you can move it, and in most cases the guaranteed income is worth keeping.
• A guaranteed annuity rate (GAR). Some older personal pensions promise to convert your pot into an income at a rate far above today’s market. That guarantee can be worth thousands and vanishes on transfer.
• Protected tax-free cash above 25%. A few schemes let you take more than the standard 25% tax-free. Moving the pot resets you to 25%.
• A protected low pension age. Certain older plans let you access money before the normal minimum age. A transfer usually removes that.
• Exit penalties. Older plans can charge a percentage to leave. Weigh that one-off cost against the ongoing saving.

If a pot is a plain modern defined contribution scheme with none of these features, it is usually a straightforward candidate to consolidate. If it has any of them, get advice or leave it where it is. The government’s free, impartial MoneyHelper guidance on transferring a pension is a good first stop.

How the transfer actually works

Once you have chosen a SIPP provider, the mechanics are handled provider-to-provider. You almost never touch the money yourself.

1. Open your SIPP with the platform you have chosen. Our guide to the best SIPP providers in the UK and what a SIPP really costs will help you pick one.
2. Start the transfer from the new provider’s side. You give them the details of each old pension, and they request the transfer on your behalf. This is a trustee-to-trustee move.
3. Choose cash or in-specie. Most consolidations are cash transfers: the old provider sells your investments and sends the value across, which you then reinvest. An in-specie transfer moves the actual holdings without selling, which avoids time out of the market but is slower and only possible if the same funds are available on both platforms.
4. Wait for it to land. A single transfer typically takes two to six weeks. Consolidating four or five pots often takes around eight to twelve weeks in total, as each scheme moves at its own pace.

The main risk in a cash transfer is being out of the market while the money is in transit, so a rising market during those weeks means you miss some growth (and a falling one means you avoid a dip). Over a long investing horizon this timing is usually minor, but it is worth knowing.

Is combining into a SIPP the right move?

Consolidation makes most sense when you are paying multiple platform fees, you want a wider or cheaper fund choice, or you simply want one account you can keep track of. It is an evidence-based way to cut costs, and lower fees are one of the few things a passive investor can reliably control.

It is the wrong move when a pot carries the guarantees above, when your current workplace pension has unusually low institutional charges you would lose, or when an employer is still contributing to a scheme (you generally keep the active workplace pension and consolidate only the dormant ones). For the wider decision on where new money should go, see SIPP vs workplace pension vs ISA, and for the full picture of the system read UK pensions explained.

Only ever deal with an FCA-authorised firm, and be alert to pension scams: a legitimate provider will never cold-call you or promise early access to your pension before the minimum age. Check any firm on the FCA register before you hand over a single detail.

Frequently asked questions

Can I transfer any pension into a SIPP? Most modern defined contribution pensions can be transferred into a SIPP. Defined benefit (final salary) pensions can be transferred too, but if the value is over £30,000 you must take regulated advice first, and it is usually better to keep the guaranteed income.

How long does it take to transfer a pension to a SIPP? A single transfer usually takes two to six weeks. Combining several pots often takes eight to twelve weeks overall, because each old provider processes its transfer at a different speed.

Do I have to sell my investments to transfer? Not always. A cash transfer sells your holdings and moves the value, which you reinvest in the SIPP. An in-specie transfer moves the actual investments without selling, avoiding time out of the market, but it is slower and needs the same funds to be available on both platforms.

Will I be charged to transfer a pension into a SIPP? Most SIPP providers do not charge to receive a transfer, and many cover exit fees from your old provider. Check each old scheme for its own exit penalty, and weigh any one-off cost against the ongoing fee saving.

Is it safe to combine all my pensions into one SIPP? It is safe when done through an FCA-authorised provider and after checking each pot for guaranteed benefits. The risks are losing valuable guarantees or being briefly out of the market during a cash transfer, not the safety of the money itself, which stays within the regulated pension system.

Should I transfer my workplace pension while I am still paying into it? Usually no. You typically keep an active workplace pension your employer is contributing to, because you would lose those contributions and often low institutional charges. Consolidation normally targets old, dormant pots from previous jobs.
