RWM Explains: What is a SIPP?

By Alex Henry, Partner, Realise Wealth Management

A Self‑Invested Personal Pension, or SIPP, is a type of pension that gives you far greater control over how your retirement savings are invested. While most people are familiar with workplace pensions, where the investment choices are limited and the day‑to‑day management is handled for you, a SIPP opens the door to a much wider range of funds, shares and other assets.

That flexibility can be incredibly valuable for the right person. We often see business owners, higher earners or clients who are particularly financially engaged wanting more involvement in how their pension is structured. A SIPP can offer that additional freedom, but it also comes with more responsibility.

How does a SIPP work?

At its core, a SIPP is still a pension. You contribute money, it’s invested, and you receive tax relief on those contributions, one of the most powerful incentives in long‑term retirement planning. The difference lies in the investment choice. Instead of being limited to a small menu of default funds, a SIPP allows you to select from a much broader universe, including:

A wide range of investment funds
Individual shares
Investment trusts
Commercial property (within certain rules)
Specialist or thematic investments

For some people, this level of choice is exactly what they want. For others, it can feel overwhelming.

When can a SIPP be helpful?

A SIPP can be particularly useful if:

You want more control over your investment strategy
You have existing investments you’d like to consolidate under one structure
You’re comfortable making decisions (with or without an adviser)
You have more complex financial planning needs, such as business ownership or irregular income

For clients who enjoy being more hands‑on, a SIPP can be a natural fit.

When might a SIPP not be the right answer?

More choice is not automatically better. SIPPs typically come with higher costs, and the responsibility for making good investment decisions sits more squarely with you. For many people, simplicity is a strength, especially if they prefer a well‑managed, low‑maintenance approach.

It’s also worth remembering that the value of a SIPP comes from how it’s used, not simply from having one. If the additional flexibility doesn’t meaningfully improve your long‑term planning, a standard personal or workplace pension may be perfectly suitable.

Should you consider a SIPP?

Ultimately, the question isn’t “Should I have a SIPP?” but “Does the added flexibility genuinely support my goals?” A SIPP can be a powerful tool, but like any tool, it works best when it’s used intentionally and in the right context.
