Which Lenders Offer SIPP Mortgages? A Market Overview

SIPP mortgages — commercial loans made to a self-invested personal pension fund to assist with the purchase of commercial property — are a specialist product that most mainstream lenders do not offer. The market is served primarily by a combination of challenger banks, specialist commercial lenders, and a small number of building societies with appetite for pension-backed lending.

This specialisation is not accidental. SIPP mortgages involve a borrower structure — a pension fund trust rather than an individual or company — that requires specific legal expertise, underwriting processes, and risk appetite. Mainstream high street banks, with their standardised processes and credit systems, find this complexity difficult to accommodate efficiently and have largely withdrawn from the market.

The result is a market of perhaps 15–20 active lenders at any given time, with significant variation in their appetite, criteria, and pricing. Understanding which category of lender is likely to be most receptive to your specific transaction is the starting point for any SIPP mortgage search.

The lenders active in the SIPP mortgage market can be broadly grouped into three categories:

• Specialist commercial lenders: Smaller, often privately owned lenders whose core business is commercial property finance. They typically have dedicated SIPP mortgage products, experienced underwriters familiar with pension fund structures, and streamlined processes. They tend to offer the broadest range of property types and the most flexible criteria, though their pricing may be slightly higher than mainstream alternatives.
• Challenger banks with commercial divisions: A number of newer bank entrants have built out commercial mortgage capability that includes SIPP lending. They often have competitive pricing and efficient processes but may have narrower criteria — for example, focusing on particular regions, property types, or fund sizes.
• Mutuals and building societies: A small number of regional building societies remain active in commercial lending, including SIPP mortgages. They typically focus on their geographic area and on simpler transaction types. Rates can be competitive for the right transaction.

No single category is universally best. The right lender depends on your specific circumstances — fund size, property type, LTV requirement, and whether you need flexibility around criteria. See our guide to how lenders assess SIPP applications for what each lender type typically looks for.

Unlike the residential mortgage market, where most lenders are accessible directly or through a small number of well-known aggregators, the SIPP mortgage market operates primarily through broker relationships. Many specialist lenders do not accept direct applications from borrowers — they work exclusively through intermediaries with whom they have established relationships.

This means that a borrower approaching the market directly is unlikely to access all available options. A specialist SIPP mortgage broker with active relationships across the lender panel can approach multiple lenders simultaneously, match your transaction to the most appropriate lender, and often access pricing not available to direct applicants.

When selecting a broker, ask specifically about their SIPP mortgage experience and which lenders they have placed cases with in the last 12 months. See our dedicated guide on the role of a SIPP mortgage broker for more detail. You can also view our lender panel to see the types of providers we work with.

Despite the variation in appetite and pricing across the market, all SIPP mortgage lenders share certain fundamental requirements:

• A qualifying SIPP: The pension fund must be established and administered by a recognised SIPP provider. Lenders maintain lists of acceptable providers; some have more restrictive lists than others.
• Minimum fund size: Most lenders require the SIPP to hold a minimum level of unencumbered assets in addition to any equity in the property. This is typically expressed as a multiple of the annual mortgage cost or as a minimum fund value. See our guide on SIPP lending criteria.
• Acceptable property type: Commercial property only — residential property is not permitted in a SIPP, and lenders will only lend against genuinely commercial assets.
• Tenancy requirements: Most lenders require the property to be let, or have a committed tenant, on a commercial lease at an open market rent. The rental income provides the primary service capability assessment.

SIPP mortgage rates are typically priced at a margin above bank base rate or SONIA (the Sterling Overnight Index Average), though some lenders offer fixed rate products for borrowers who prioritise payment certainty. The margin over base rate varies by lender, LTV, property type, and tenant quality.

Product terms — fixed vs. variable, interest-only vs. capital repayment, loan term — vary considerably across lenders. SIPP mortgages are most commonly written on an interest-only basis, preserving the fund's cash position for investment, though capital repayment is available from some lenders. Loan terms range from five to fifteen years, with some lenders extending further for stronger transactions.
