SIPP vs Personal Pension Explained: Which Type Of Pension Suits You?

A personal pension is a defined contribution pension you set up yourself, separately from any workplace arrangement. You pay contributions into the pension, you receive tax relief on those contributions at your marginal rate, the money is invested, and at retirement you can access the pot from age 55 (rising to 57 in April 2028).

Most standard personal pensions are run by major UK insurers and pension providers — Aviva, Standard Life, Royal London, Scottish Widows, Legal & General, and others. The provider gives you access to a curated investment range, typically a selection of multi-asset funds, lifestyle strategies, and a smaller number of single-asset funds covering equities, bonds and cash.

The defining feature of a standard personal pension is simplicity. The investment choices are bounded, the platform is straightforward, charges are usually a single annual management fee, and the provider handles the underlying administration. For many people — particularly those who do not want to actively manage their pension investments — that simplicity is exactly the point.

A Self-Invested Personal Pension is a personal pension that gives you much wider control over what the pension is invested in. The underlying tax wrapper is the same — the same tax relief, the same access rules, the same contribution limits, the same lump sum allowance, the same eventual taxation of withdrawals. The difference is the investment universe and the level of active management involved.

A SIPP typically allows you to invest in:

• Individual shares listed on UK and (in most cases) overseas exchanges
• A much wider range of funds — often thousands rather than dozens
• Exchange-traded funds (ETFs) and investment trusts
• Bonds and gilts
• Commercial property (in full SIPPs offered by specialist providers)
• Other investments that meet HMRC pension rules

The broader the investment range, the more responsibility sits with the saver to choose and review the investments. Most modern SIPPs are offered by investment platforms — Hargreaves Lansdown, AJ Bell, Interactive Investor, Vanguard, Fidelity and others — rather than insurers.

Investment choice. This is the headline difference. A standard personal pension offers tens of funds; a SIPP offers thousands of funds plus individual stocks, ETFs and other instruments. For most people, the curated range in a standard personal pension covers what they need; for those who want specific holdings (individual companies, a particular ETF, themed investment trusts), a SIPP is usually the only route.

Responsibility. With a personal pension you typically pick a default lifestyle strategy or one or two managed funds, and the provider handles the rest. With a SIPP you choose individual holdings and you are responsible for reviewing and rebalancing them. This can be a benefit (control) or a drawback (effort), depending on how engaged you want to be.

Cost structure. Standard personal pensions are usually a single annual percentage charge that covers everything. SIPP charges are split: a platform fee (often a percentage of the pot, sometimes capped), plus the cost of the underlying investments (fund management fees, dealing fees, foreign exchange where relevant). Whether a SIPP works out cheaper depends on what you hold, how often you trade, and how big the pot is.

Flexibility at retirement. Both can be used for flexi-access drawdown, UFPLS, annuity purchase, or any combination. The income options are the same. Many SIPP platforms have richer drawdown functionality (ability to vary withdrawals more easily, more reporting tools), but the underlying tax rules are identical.

Administration. Standard personal pensions tend to feel more "set and forget"; SIPPs tend to feel more like an investment account with pension tax benefits. Both involve the same regulatory protections (FCA-regulated providers, Financial Services Compensation Scheme cover within limits).

Charges have moved a lot over the last decade. SIPPs used to be noticeably more expensive than standard personal pensions; today the gap has narrowed significantly, and on larger pots a SIPP can actually be cheaper.

Three things drive the difference:

The platform charge on a SIPP is typically a percentage of the pot (often 0.20%–0.45%, sometimes capped above certain thresholds). On a standard personal pension this same fee is usually rolled into a single annual management charge of 0.30%–1%, depending on the provider.

The fund or investment cost is separate on a SIPP — you choose your funds, you pay each fund's ongoing charge (typically 0.05%–1% depending on whether you hold passive index funds or actively managed funds). On a standard personal pension the fund range is usually limited to the provider's own funds, and the charge is bundled.

Dealing fees apply on SIPPs for individual share, ETF and sometimes fund trades. Standard personal pensions don't usually have dealing fees because switches between the provider's funds are typically free.

For someone holding low-cost index funds on a competitive SIPP platform, the total cost can be 0.30%–0.50% per year. For someone in a typical workplace personal pension's default fund, the equivalent might be 0.50%–0.75%. For someone on an older insurer-run personal pension that hasn't been reviewed in years, charges can be over 1%. Reviewing charges is usually the single most consequential pension housekeeping move people overlook.

A standard personal pension tends to make sense for people who want a low-effort pension — they're happy with a curated investment range, they don't want to actively manage individual holdings, and they value simplicity over investment flexibility. Lifestyle strategies (where the investment mix automatically de-risks as you approach retirement age) are particularly common in this format and work well for many people who would rather not have to think about their investments at all.

A standard personal pension can also make sense for smaller pension pots where SIPP platform fees become a higher proportion of the pot. Many providers have minimum-pot levels below which a SIPP doesn't make economic sense.

A SIPP tends to make sense for people with larger pension pots, particularly those consolidating multiple workplace pensions into one place, and for those who want specific investment holdings the standard personal pension doesn't offer. Affluent savers in their 50s and 60s with a pot of £100,000+ who want to take a more active role in their retirement investing — for example by holding global passive ETFs, a specific tilt towards income-generating investments, or low-cost index funds across multiple asset classes — often find a SIPP gives them flexibility a standard pension can't match.

A SIPP also tends to suit people preparing for flexi-access drawdown in retirement, because the platform tools for managing drawdown — running models, varying withdrawals, holding income-generating funds alongside growth funds — are typically richer on SIPP platforms than on insurer-run personal pensions.
