If your business needs its own premises — an office, workshop, warehouse, retail unit, or similar — there’s a route worth knowing about that most business owners never consider: having your pension buy the building, rather than the company or you personally. It sounds unusual the first time you hear it, but it’s a well-established, HMRC-recognised structure, and for the right business, it can be one of the more powerful things a SIPP can do.
This is general information, not property, tax, or financial advice — this is a genuinely complex area with real risks if structured or run incorrectly, and it needs a specialist (SIPP provider, solicitor, accountant) involved from the outset, not after the fact.
The basic structure
A SIPP can directly purchase commercial property — offices, workshops, warehouses, retail units, and similar business premises are all eligible; residential property is not permitted under any circumstances, and attempting to hold it inside a SIPP triggers severe tax penalties.
The most common version of this: your SIPP buys the premises your own business occupies, and your business then pays rent — to your pension, rather than to a landlord or a commercial mortgage lender. Two things happen at once:
- The business gets a tax-deductible expense (the rent), just as it would with any commercial lease.
- That same rent flows into your pension, tax-free, rather than to an external landlord’s pocket.
Effectively, money that would otherwise leave the business permanently as rent instead builds your own retirement pot.
What makes this different from just buying the building yourself
You could, of course, simply buy the premises personally or through the company and let the business occupy it. What the SIPP route adds:
- Rental income inside the SIPP is free of income tax, and any growth in the property’s value is free of Capital Gains Tax while it stays in the pension — unlike owning it personally, where both would typically be taxable.
- The SIPP can borrow up to 50% of its net value to help fund the purchase, via a specialist commercial mortgage — useful if the SIPP doesn’t yet hold enough to buy outright.
- It sits inside your pension’s inheritance treatment, generally more favourable on death than a personally-held property, though rules here have been shifting and are worth checking current guidance on specifically.
The rules that make or break this structure
Because your own business renting from your own pension is what HMRC calls a “connected party transaction,” it’s permitted — but only within strict boundaries:
- Rent must be genuine market rate, evidenced by an independent RICS valuation — not a discounted, convenient figure that quietly subsidises the business.
- A formal, properly documented commercial lease is required, even though landlord and tenant are effectively connected.
- Rent has to be paid in full and on time, on standard commercial terms — informal arrangements or arrears can create serious complications.
- If rent is set too low, or paid inconsistently, HMRC can treat it as an “unauthorised payment” from the pension — a significant tax penalty, not a minor technicality.
This is precisely why specialist advice matters here far more than in most of what’s covered on this site: getting the valuation, lease, and ongoing administration wrong doesn’t just cost you the tax benefit, it can trigger a real tax charge.
What you give up
- Control: the SIPP (via its trustee/provider) legally owns the property, not you or the company directly.
- Liquidity: a meaningful chunk of your pension is now tied up in a single illiquid asset rather than diversified investments — the opposite of the “spread the risk” principle that usually makes a pension safer than relying purely on the business.
- Flexibility: exiting or restructuring the arrangement later — selling the property, changing tenants, winding things down — is considerably more complex than adjusting a normal pension portfolio.
- No personal guarantees on SIPP borrowing — if things go wrong, the lender’s recourse is limited to the property and the pension, which protects you personally, but also makes SIPP commercial mortgages somewhat harder to arrange and typically priced slightly above standard commercial rates.
Where this fits for a growing business
This structure suits a business that’s already committed to specific, long-term premises, has (or is building toward) a SIPP substantial enough to fund a meaningful deposit, and wants rent payments to build personal retirement wealth rather than disappear to an external landlord. It suits a very early-stage or fast-pivoting business much less well — tying pension assets to premises you might outgrow or need to leave within a few years works against the flexibility a growing business often needs.
For business partners or director teams looking at this together, it’s also worth being aware of the SSAS (a related but distinct pension structure, more commonly used by multiple company directors), which allows features a standard SIPP doesn’t — including lending some of the pension’s funds back to the sponsoring company itself, and easier pooling of multiple people’s pensions into one property purchase.

SIPP commercial property transactions are complex and connected-party rules carry real financial risk if not followed precisely. Take specialist advice from a SIPP provider experienced in commercial property, a solicitor, and an accountant before pursuing this structure.
