About this guide
A SSAS and a SIPP are both pension structures with significant tax advantages, but they are designed for different purposes and suit different director profiles. This guide is for UK company directors who are comparing the two structures and want a thorough, honest account of the differences — including the loanback facility (available only in a SSAS), the commercial property mechanics of each, the cost comparison, and the specific scenarios where each is the stronger choice. By the end, you will have enough information to identify which structure fits your situation — or to recognise that you need a specialist conversation to decide.
What you'll learn in the SSAS vs SIPP Comparison Guide
- The fundamentals side by side. What each structure is at its core — SSAS as an occupational scheme tied to a limited company; SIPP as a personal pension belonging to the individual. The architectural difference matters for everything that follows.
- The complete feature comparison table. A structured head-to-head across eleven dimensions: scheme type, who can be a member, employer contributions, loanback availability, multi-member pooling, commercial property, residential property prohibition, administration complexity, annual costs, minimum viable fund size, and connection to the business.
- The loanback: why it is the critical differentiator. The SSAS loanback allows the fund to lend up to 50% of its net assets to the sponsoring company. SIPPs cannot do this under any circumstances. The guide explains exactly how this facility works and why it is the deciding factor for many directors.
- Commercial property in both structures. Both a SSAS and a full SIPP can invest in commercial property — but the mechanics differ. The guide explains the pooling advantage a SSAS provides, why platform SIPPs typically cannot hold property at all, and when a full-service SIPP is a genuine alternative.
- Employer contributions: the key nuance. Both structures accept employer contributions, but the occupational vs personal distinction creates practical differences in how contributions interact with the business and the pension.
- Four director scenarios with recommendations. Real-world profiles — a sole director building a property strategy, a freelance consultant wanting low-cost simplicity, three directors pooling to buy office premises, and a director with a legacy defined benefit pension — each with a clear, reasoned recommendation.
- A decision framework. Six questions that, answered honestly, identify the right structure for your circumstances.
This guide is written for you if…
- You are a UK company director who has heard of both SSAS and SIPP and wants an impartial, detailed comparison before making a decision
- You are specifically wondering whether the SSAS loanback could work for your business and want to understand the full rules before exploring further
- You have an existing SIPP and are wondering whether a SSAS would serve you better as your business grows
- You are a director with business partners and want to understand whether pooling pension funds makes sense in your circumstances
- You want to understand commercial property investment through a pension but are unsure which structure to use
This guide is educational. It does not constitute financial advice and does not make a recommendation for your personal circumstances. For that, a specialist conversation is required.
Straight from the guide
“The single most important functional difference between a SSAS and a SIPP — and the reason many directors choose a SSAS — is the loanback facility. A SSAS can lend up to 50% of its net asset value to the sponsoring employer. SIPPs cannot do this. There is no equivalent facility in a personal pension.”
“There is a significant overlap zone — directors for whom either a SSAS or a well-constructed full SIPP could work. The decision may come down to whether you want to keep the pension entirely separate from your business (SIPP) or integrated with it (SSAS).”

No. Your details are held by Holtram TLPI Ltd and used only for the purposes described. We do not sell or share personal data with third parties for marketing purposes.
Can a SIPP do everything a SSAS can do?
No. The key capability a SIPP cannot replicate is the loanback — the ability to lend up to 50% of the fund back to the sponsoring company. Multi-member pooling is also unique to the SSAS. Commercial property investment is available in both structures, though the mechanics differ. The guide covers all of this in full.
Does TLPI ever recommend a SIPP over a SSAS?
Yes. Not every director needs a SSAS. If your fund is small, your investment strategy is simple, and you have no need for the loanback or multi-member pooling, a SIPP may be the more cost-effective choice. The guide includes four real-world director profiles with honest, reasoned recommendations — including cases where the SIPP is the better answer.
