What is a SIPP?
A Self-Invested Personal Pension (SIPP) is a type of defined contribution pension that gives you much greater control over how your retirement savings are invested. Unlike most workplace pensions, which offer a limited range of pre-selected funds, a SIPP allows you to choose from a wide range of investments including individual shares, bonds, exchange-traded funds, investment trusts, and commercial property.
SIPPs are provided by investment platforms and pension providers, and they offer the same tax benefits as any other UK pension: tax relief on contributions, tax-free growth within the pension wrapper, and the ability to take 25 percent of your fund as tax-free cash at retirement.
What is a workplace pension?
A workplace pension is a pension scheme arranged by your employer. Since auto-enrolment was introduced in 2012, all employers are required to offer a workplace pension scheme and automatically enrol eligible employees. The employer must contribute at least 3 percent of qualifying earnings, with the employee contributing at least 5 percent, for a total minimum contribution of 8 percent.
Most workplace pensions are defined contribution schemes run by large pension providers such as Nest, Aviva, Scottish Widows, or Legal and General. They typically offer a default investment fund and a small selection of alternative funds.
Key differences between a SIPP and workplace pension
Investment choice
This is the most significant difference. A workplace pension typically offers between 5 and 30 investment funds, while a SIPP can provide access to thousands of investments. If you want to choose your own shares, invest in specific sectors, or build a highly customised portfolio, a SIPP provides the flexibility to do so.
However, more choice is not always better. Research consistently shows that the default fund in a workplace pension, which is professionally managed and automatically adjusts its risk profile as you approach retirement, performs perfectly well for most savers. Having more options does not guarantee better outcomes, and it requires more time, knowledge, and engagement to manage effectively.
Employer contributions
This is the workplace pension's biggest advantage and one that a SIPP simply cannot match. Your employer's contributions are effectively free money. If your employer contributes 3 percent of your qualifying earnings, that represents an immediate 60 percent boost to your own 5 percent contribution before any investment growth.
If you move your contributions from your workplace pension to a SIPP, you lose the employer contributions. For this reason, it almost never makes sense to stop contributing to your workplace pension in favour of a SIPP. The right approach for most people is to contribute enough to their workplace pension to capture the full employer match, and then consider directing any additional savings to a SIPP if the investment options are important to them.
Charges
Workplace pension charges are capped by law at 0.75 percent per year for default funds, and many large employer schemes negotiate rates well below this, sometimes as low as 0.2 to 0.4 percent. SIPP charges vary widely depending on the provider and the investments chosen. Platform fees typically range from 0.15 to 0.45 percent, with additional fund management charges on top. If you invest in individual shares, dealing charges also apply.
For passive index fund investing, a low-cost SIPP can be competitive with workplace pensions on charges. For more active or complex investment strategies, SIPP costs can be significantly higher.
Consolidation and control
If you have multiple old workplace pensions from previous employers, a SIPP can be a useful vehicle for consolidating them into a single account. This makes your overall pension position easier to monitor, may reduce total charges, and gives you a consistent investment strategy across all your pension savings.
However, before transferring any old workplace pension to a SIPP, check whether the existing pension has any valuable guarantees, enhanced tax-free cash entitlements, or particularly low charges that would be lost on transfer.
Drawdown options
Most modern SIPPs offer flexi-access drawdown as standard, giving you full flexibility over how you take your income in retirement. Some workplace pensions also offer drawdown, but others require you to transfer to a different product at retirement. Check what options your workplace pension provides before assuming you need to move to a SIPP for retirement.
When a SIPP makes sense
- You want to invest in specific shares, bonds, or other assets not available through your workplace pension
- You want to consolidate multiple old pensions into one place
- You are an experienced investor comfortable managing your own portfolio
- You are self-employed and do not have access to a workplace pension
- You want to make additional pension contributions beyond your workplace scheme
When a workplace pension makes sense
- You want to benefit from employer contributions, which represent free money
- You prefer a simple, hands-off approach to pension investing
- You are happy with the default fund and do not want to actively manage your investments
- Your employer scheme has particularly low charges
- You benefit from salary sacrifice, which saves both income tax and National Insurance
Can you have both?
Yes, and for many people this is the optimal approach. Contribute to your workplace pension to capture the employer match and any salary sacrifice benefits, then direct additional savings to a SIPP if you want greater investment control or if you are consolidating old pensions.
There is no limit on the number of pensions you can hold, though you need to keep within the overall annual allowance of 60,000 pounds across all pension contributions.
Getting advice
If you are unsure whether a SIPP is right for you, or you want help choosing the right investments within a SIPP, a pension adviser can provide personalised guidance. They can review your workplace pension, assess whether a SIPP would benefit you, and help you construct an investment strategy aligned with your retirement goals and risk tolerance.
The bottom line
Neither a SIPP nor a workplace pension is universally better than the other. The right choice depends on your circumstances, level of investment knowledge, and retirement goals. For most employees, the workplace pension with its employer contributions should be the first priority. A SIPP can complement this as a vehicle for additional savings and greater investment flexibility.
