Diversification: Should Your SIPP Hold Property AND Equities?

A pension is a long-term vehicle — typically spanning 20 to 40 years from initial contribution to full drawdown. Over that timeframe, both commercial property and equity markets will experience cycles of growth, stagnation, and decline. Concentrating a pension entirely in one asset class amplifies the impact of any single downturn at the worst possible time: when you need to draw income.

Diversification within a SIPP is not just about maximising returns; it is about managing the risk of large losses at inopportune moments. A SIPP that holds only commercial property may generate excellent returns but creates a liquidity crisis if a forced sale is required during a property market downturn. A SIPP holding only equities may be highly liquid but is exposed to the kind of sentiment-driven 40% drawdown that has occurred in UK equities several times in the past 30 years.

Commercial property serves a specific function within a diversified pension: it provides a stable, income-generating, inflation-linked asset that behaves differently to equities over most market cycles. During equity market drawdowns, commercial property (particularly well-let industrial and office assets) typically experiences slower and smaller value declines, cushioning the overall pension portfolio. The rental income stream continues largely unaffected by stock market sentiment.

Property also provides a natural hedge against inflation over long periods. Upward-only rent reviews — common in UK commercial leases — mean that rental income grows with inflation, protecting the real value of pension income. Equities can also provide inflation protection over the very long run, but with significantly more short-term volatility. For pension holders within 10–15 years of retirement, the income stability of property becomes progressively more valuable.

Equities within a SIPP perform a different function to property: they provide liquidity, global diversification, and the potential for higher capital growth over long time horizons. A SIPP that holds a commercial property alongside a diversified equity portfolio can use the liquid equity component to meet drawdown requirements or rebalance the portfolio without the need to sell property.

Global equity exposure is particularly valuable as a diversifier against UK-specific risks. UK commercial property returns are tied to the domestic economy; a global equity portfolio provides exposure to faster-growing economies and sectors unavailable in UK commercial property. Technology, healthcare, and emerging market exposure through equities complements the UK income focus of a commercial property holding.

For SIPP investors who own their own business premises, equities provide diversification away from concentration in a single business, single tenant, and single property market — three forms of concentration that reinforce each other in a stress scenario where the business struggles.

There is no single correct allocation between property and equities — it depends on pot size, age, income requirements, and risk tolerance. As a general framework, we observe the following among our clients: pension holders in their 40s and early 50s typically hold 30–50% in direct commercial property (often their business premises) with the balance in a diversified equity portfolio; those in their late 50s and early 60s approaching retirement often shift toward 50–70% property for income stability; those in active drawdown manage liquidity carefully, maintaining enough liquid assets to cover several years' drawdown without forced property sales.

The practical constraint on property allocation is the minimum SIPP pot size needed to fund direct commercial property meaningfully. A SIPP needs at least £100,000–£150,000 in liquid assets to make a sensible commercial property purchase (allowing for deposit, transaction costs, and a liquidity buffer). Below this level, equities and property funds are typically more practical than direct property ownership.

For SIPP investors who want property exposure before they have sufficient capital for a direct purchase, commercial property funds (available through most platform SIPPs) provide a liquid alternative. These funds invest in diversified portfolios of commercial property and offer daily or weekly liquidity. Returns typically lag direct property ownership (management fees, cash drag, and forced selling in redemption periods reduce returns) but the diversification and liquidity benefits are real.

We generally view property funds as a stepping stone rather than an end destination for serious SIPP property investors. Once a SIPP has sufficient capital, direct ownership offers superior control, income certainty, and — for business owners who can occupy the property — the unique rental deduction benefit.
