Should I choose a SIPP or a workplace pension?
A workplace pension should generally be your first priority if your employer offers matching or minimum auto-enrolment contributions, since employer contributions are effectively free money you would lose by contributing elsewhere instead. A SIPP (Self-Invested Personal Pension) is best used to complement a workplace pension -- for self-employed income, additional voluntary savings, or consolidating old pensions with more investment control.
Full answer
The choice between a SIPP and a workplace pension is not usually an either/or decision for most employees -- understanding how they complement each other helps maximise your total retirement savings efficiently. **Always capture employer contributions first** If you are employed and your employer offers pension contributions (whether the statutory auto-enrolment minimum or a more generous scheme), you should almost always contribute enough to your workplace pension to receive the maximum available employer contribution before considering a SIPP for additional savings -- turning down free employer money in favour of a SIPP (where you fund 100% of the contribution yourself) rarely makes financial sense. **What a SIPP offers that a workplace pension often doesn't** A SIPP typically offers a much wider range of investment choices than many workplace pension default funds (which are often limited to a handful of pre-selected fund options), giving you greater control over exactly how your pension savings are invested -- this appeals particularly to more engaged investors who want to actively manage their asset allocation rather than accept a default fund. **Consolidating old workplace pensions** A SIPP is commonly used to consolidate pension pots from previous employers into a single account, making it easier to track your total retirement savings and manage investment choices in one place -- though it is worth carefully checking whether any old workplace pension has valuable guarantees or benefits (such as a guaranteed annuity rate) that could be lost by transferring out, before consolidating. **Self-employed people typically rely on SIPPs** Since self-employed individuals have no employer to make pension contributions, a SIPP (or a similar personal pension) is usually the primary retirement savings vehicle, funded entirely from their own contributions, which still attract tax relief at their marginal rate. **Using a SIPP for additional contributions above workplace minimums** Higher earners or particularly engaged savers might use a SIPP alongside their workplace pension for ADDITIONAL contributions beyond what their employer scheme accepts or beyond the employer-matched amount, particularly if they want more control over how these extra contributions are invested compared with their workplace scheme's options. **Costs can differ** Workplace pensions often benefit from lower charges due to the scheme's collective bargaining power with the pension provider, while SIPP costs vary significantly by provider and can sometimes be higher, particularly for smaller pot sizes -- compare the annual charges of both options carefully, since fees compound over the long term and can meaningfully affect your eventual retirement pot. **Worked example** Someone earning £45,000 contributes 5% (with a 3% employer match) to their workplace pension, capturing the full employer contribution. They also open a SIPP for an additional £100 a month of voluntary saving, invested in a wider range of funds than their workplace scheme offers, giving them more control over this additional portion of their retirement savings while still capturing all the free employer money through the workplace scheme. **Practical tip** Use the SIPP calculator alongside your workplace pension figures to model your total combined retirement savings across both vehicles, and always confirm you are contributing enough to your workplace pension to capture the maximum employer match before directing any additional retirement savings into a SIPP.
