What Is a Full SIPP & How Does It Work?
A full SIPP (Self-Invested Personal Pension) is a flexible pension scheme that gives you complete control over your retirement savings, and unlike traditional SIPP types, full SIPPs allows you to choose from an even wider variety of investments, including stocks, bonds, commercial properties, and more.

This flexibility lets you diversify your retirement portfolio, which could potentially lead to higher returns; however, managing a full SIPP requires a hands-on approach, as you are responsible for making investment decisions.
It’s important to have a strong understanding of financial markets, as while the potential for higher returns is appealing, it’s crucial to recognise that this comes with higher risk.
So, the bottom line?
Always carefully consider your risk tolerance and reasons to invest before investing through a Full SIPP.
What Are the Key Features of Full SIPPs?
The key features of full SIPPs are tax relief up to certain contribution limits, other tax advantages, and a wide range of investment choices.
Let’s take a closer look at each of these:
What Are the Contribution Limits on a Full SIPP?
While there are no specific contribution limits on a Full SIPP, there is an annual allowance for tax relief purposes; you can contribute up to 100% of your annual earnings or £60,000 (whichever is lower) and still receive tax relief.2
Any contributions made beyond this annual allowance will not qualify for tax relief.
However, if you haven’t fully used your annual allowance in the previous three tax years, you may be able to carry it over and contribute more in the current tax year.
Are There Tax Advantages With a Full SIPP?
Yes, a Full SIPP provides several tax advantages; firstly, contributions to your SIPP are made from pre-tax income, meaning they can reduce your taxable income for the year, and any investment growth within the SIPP is tax-free, meaning you won’t pay capital gains or income tax on your investments.
Though there are many advantages, it is always a good idea to consult with a financial adviser or tax expert when making decisions about pensions and investments.

All of these advantages include:
- Tax relief on contributions: The government adds tax relief at the 20% basic rate. So, if you contribute £80, the government will add another £20, making a total contribution of £100. You can claim back even more through your tax return if you’re a higher and additional-rate taxpayer.3
- Tax-free growth: Growth on investments held within a SIPP is free of UK capital gains tax and income tax.
- Tax-free lump sum: Once you reach the age of 55, you can typically take up to 25% of your pension pot as a tax-free lump sum.4
- Flexibility in drawing income: After taking any tax-free lump sum, you can use the remainder of your SIPP to provide a taxable income, either through purchasing an annuity or via income drawdown.
- Inheritance benefits: SIPPs can be passed on to your beneficiaries. Depending on when you die (before or after age 75), there may be tax implications, but SIPPs can be an effective tool for estate planning.5
What Types of Investment Can You Choose?
The types of investment you can choose for a Full SIPP generally encompass a wide range of asset classes, including commercial preperties, hedge funds, and foreign currency.
It's crucial to remember that while SIPPs offer a vast range of investment options, each investment type comes with its own risk profile.
These investment options include:
- Stocks and shares
- Bonds
- Funds
- Exchange-traded funds (ETFs)
- Commercial property
- Commodities
- Cash
- Structured products
- Hedge funds
- Private equity
- Trusts (including Real Estate Investment Trusts (REITs))
- Foreign currency
What’s the Difference Between a Full SIPP & Other Types of SIPP?
The main difference between a Full SIPP and other types of SIPPs lies in the level of flexibility and the range of investment options available, with a Full SIPP offering extensive control over your pension and a wide array of asset options to invest in.
This makes it ideal for experienced investors who want to manage their own portfolio and have the expertise to make informed decisions.
Additionally, other or traditional SIPPs tend to cater to those looking for simpler, more straightforward pension solutions, often with a lower cost structure.

Here are some side-by-side considerations:
What Type of Advice Should You Seek for Different SIPPs?
When it comes to choosing the right SIPP for your retirement needs, you should always seek professional financial advice to make the best decisions for yourself and your investments.
For example:
- Full SIPP: advice can be particularly valuable, as these pensions offer extensive investment flexibility. You can appoint a discretionary fund manager to take care of your investments and help you navigate them, which is often beneficial for more experienced investors looking for personalised management.
- Other SIPPs: while professional advice is still recommended, these schemes tend to be more suited to DIY investors who are comfortable managing their pension funds with less external input. These platforms often offer more straightforward investment options and can be managed using online tools. Seeking guidance on tax reliefs and overall pension strategy is always a wise decision.
How Do Full SIPPs Compare to Other SIPPs in Terms of Control and Flexibility?
Full SIPPs offer more control over investment decisions, compared to other SIPPs with typically limited investment choices.
For example:
- Full SIPP: these provide a high level of control and flexibility. You can make frequent changes to your investments, including contributions and withdrawals, without the usual restrictions. This flexibility lets you tailor your pension scheme and adjust investments based on market conditions and personal circumstances.
- Other SIPPs: these may come with more limitations. They might restrict how often you can trade, change investments, or withdraw funds without incurring additional fees. These SIPPs are typically more suitable for those who want a simpler, more hands-off approach to managing their pension.
What Are the Fees & Charges for Full SIPPs Compared to Other SIPPs?
Full SIPPs typically come with higher fees due to increased investment flexibility, compared to other types of SIPPs, which are usually more affordable and offer cheaper options.
For example:
- Full SIPP: this tends to have higher fees due to the extensive range of investment options and the added flexibility they offer. You may encounter set-up fees, annual management fees, transaction fees, and potentially advisery fees if you choose to appoint a fund manager.
- Other SIPPs: other types of SIPPs are designed to be more cost-effective, typically coming with fewer investment options and less flexibility, which keeps their fees lower.
How Do Contributions Differ Between Full SIPPs & Other SIPPs?
Full SIPPs typically allow more flexible contribution patterns compared to other pension schemes.
For example:
- Full SIPP: these provide greater flexibility when it comes to contributions, typically allowing for larger contribution amounts and offer more flexibility in terms of regular and one-off payments.
- Other SIPPs: these may have stricter guidelines on contribution amounts, frequencies, and methods, often designed for a more standardised investment approach.
What Are the Investment Options in a Full SIPP Compared to Other SIPPs?
Compared to other SIPPs, full SIPPs offer a wider range of investment options, which include hedge funds and unlisted shares.
For example:
- Full SIPP: these offer a much wider range of investment options compared to other pension plans, giving you the flexibility to invest in commercial property, individual stocks and shares, unlisted shares, and more, allowing you to diversify your portfolio and take control of your investment strategy.
- Other SIPPs: in contrast, these tend to have more restricted or specialised investment choices, mainly focusing on standard assets like listed stocks, bonds, and mutual funds.
What Are the Benefits & Risks of Full SIPPs?
The benefits of full SIPPs include greater control and flexibility over your retirement savings and potentially higher returns; however, the risks include the responsibility of managing your own investments and poor investment choices potentially leading to financial losses.
Weighing these ensures you can decide, wholly informed, whether full SIPPs are a good idea for you.
Let's take a look at the pros and cons:
What Are the Benefits of Full SIPPs?
Full SIPPs provide a range of benefits, including flexibility in investment choices which enables you to tailor your retirement plan to your specific goals and risk tolerance.
Let’s take a closer look at all the advantages:

- Consolidation: Full SIPPs enable individuals to consolidate multiple pension pots into a single account, simplifying pension management.

What Are the Risks of Full SIPPs?
While Full SIPPs offer significant flexibility, they come with a range of risks that need to be carefully considered; one of the main risks is the inherent investment risk associated with the wide variety of assets you can choose from, potentially leading to higher losses.
Let’s explore the risks associated:
- Investment Risk: With a Full SIPP, investors have more control over their investments, but this also means they bear the full responsibility for investment choices. Poorly performing investments or market downturns can lead to financial losses.
- Complexity: Managing a Full SIPP can be complex, especially for those without investment expertise. Making uninformed investment decisions can have detrimental consequences.
- Risk of Overconcentration: Investors may be tempted to overconcentrate their investments in a particular asset class, sector, or region, which can increase risk if that investment performs poorly.
- Lack of Diversification: Failing to diversify investments can increase the overall risk of the pension portfolio. A lack of diversification can result in more significant losses during market downturns.
- High Fees: Managing a Full SIPP may involve higher fees, especially if investors engage in frequent trading or have a complex investment strategy.
- Liquidity Risk: Some investments within a Full SIPP may not be readily liquid, making it difficult to access funds in emergencies.
- Regulatory Changes: Changes in pension regulations or tax laws can impact the benefits and rules associated with Full SIPPs.
- Inheritance Tax Risk: While Full SIPPs can offer estate planning benefits, the rules around inheritance tax are subject to change, and individuals should stay informed about potential impacts.
- Long-Term Commitment: Full SIPPs are intended for long-term retirement planning. Withdrawing funds early may result in penalties and reduced retirement income.
- Market Volatility: Market fluctuations can impact the value of investments within the Full SIPP, potentially affecting the overall pension fund's performance.

To qualify for a Full SIPP, you generally need to be a UK resident aged between 18 and 75; however, SIPP eligibility criteria can vary slightly depending on the provider.
