What Can You Invest in a SIPP?

Introduction

A Self-Invested Personal Pension (SIPP) allows pension savings to be invested in a wider range of assets than some standard personal pensions. However, this flexibility operates within a defined legal and regulatory framework. Not all investments are permitted within a UK pension, and additional restrictions may be applied by pension providers.

Understanding what can be invested in within a SIPP involves distinguishing between what UK pension legislation allows and what individual providers choose to support operationally. This guide explains the main categories of investments that can typically be held in a SIPP and how investment permissions are defined.

How Investment Rules Work in a SIPP

All SIPPs are registered UK pension schemes. This means:

• investments must comply with UK pension legislation
• certain asset types are restricted or prohibited
• providers may impose additional limits

The presence of a wider investment range does not remove pension rules or regulatory oversight.

Permitted Investments Under UK Pension Rules

UK pension legislation allows registered pension schemes to hold a broad range of standard assets, subject to restrictions designed to prevent misuse of pension tax advantages.

Permitted assets are often described at a high level rather than as an exhaustive list.

Listed Shares

SIPPs may allow investment in:

• shares listed on recognised stock exchanges
• UK and overseas equities
• exchange-traded securities

These investments are typically held through nominee or custody arrangements within the pension structure.

Collective Investment Schemes

Many SIPPs allow investment in regulated collective investment vehicles, such as:

• unit trusts
• OEICs
• investment funds
• exchange-traded funds (ETFs)

Funds may provide exposure to a range of asset classes and markets within a single investment.

Cash Holdings

Cash can usually be held within a SIPP. Cash may be used:

• to receive contributions
• to hold proceeds from asset sales
• as an uninvested balance

Cash held within a SIPP remains subject to pension rules and provider terms.

Fixed-Interest and Bond Investments

Some SIPPs permit investment in:

• government bonds
• corporate bonds
• fixed-interest securities

Availability depends on provider policies and platform arrangements.

Investment Restrictions and Prohibited Assets

Certain assets are restricted or prohibited within UK pensions. These restrictions exist to protect the integrity of the pension tax system.

Examples of restricted areas include:

• assets that provide personal use or enjoyment
• certain forms of tangible property
• structures that fall outside permitted investment definitions

Provider policies may further restrict access to specific asset types even where legislation permits them.

Provider Policies and Operational Limits

In practice, what can be invested in within a SIPP depends on:

• the provider’s platform
• custody and settlement arrangements
• compliance and operational considerations

Two SIPPs operating under the same legislation may offer different investment access due to provider policy rather than legal constraint.

SIPPs, Risk and Investment Responsibility

All SIPPs are defined contribution pensions. This means:

• investment performance affects the pension value
• investment values can rise or fall
• outcomes are not guaranteed

The range of investments available does not change the fundamental nature of investment risk.

SIPPs and International Investments

Some SIPPs allow access to overseas investments, subject to:

• exchange listing requirements
• regulatory permissions
• provider support

In an international context, SIPPs may be referred to as International SIPPs or iSIPPs, although these remain UK-registered pensions.

How Investment Choice Fits With Other SIPP Features

Investment choice interacts with:

• pension charges
• administration
• dealing and custody arrangements

A wider investment range may involve additional layers of administration and cost, depending on the structure of the SIPP.

Common Misunderstandings About SIPP Investments

“A SIPP allows any investment”

All investments must fall within UK pension rules and provider policies.

“International SIPPs are offshore pensions”

An International SIPP remains a UK pension.

“Investment choice removes pension restrictions”

Access, tax and allowance rules still apply.

“More choice guarantees better outcomes”

Investment outcomes depend on performance and risk, not choice alone.

Summary

A SIPP allows pension savings to be invested in a wider range of assets than some personal pensions, within the limits set by UK pension legislation and provider policies. Investment access depends on both legal permissions and operational support.
