Building a rental portfolio without interest is now genuinely possible in Britain, and the market has quietly become competitive: five providers write Shariah-compliant buy-to-let finance, with published rates at two of them, HMO coverage at three, and structures ranging from bank co-ownership to a no-debt partnership. It has also kept one uncomfortable feature worth understanding before anything else: almost none of it is FCA regulated. Everything below was verified against provider publications on August 6, 2026.

First, the regulation warning
Buy-to-let finance for investment purposes generally sits outside FCA product regulation, in the conventional market and the halal one alike. StrideUp prints on every buy-to-let page that its BTL purchase plans are not regulated by the Financial Conduct Authority; Offa's firm is FCA authorised but its BTLPP sits outside product regulation; Nomo states plainly that FSCS and FOS do not apply to its rental property finance. The Shariah certification is just as real on these products; the consumer protections are not. Read each provider's risk documents, because default remedies (lease termination, receiver of rent, repossession, shortfall liability) are spelled out there and they have teeth.

Gatehouse: the published-rate bank
Gatehouse Bank is the only UK Islamic bank publishing full buy-to-let ranges, on the same diminishing musharakah co-ownership structure as its Home Purchase Plan, with separate Shariah certificates for individual and corporate landlords approved by its board under Sheikh Nizam Yaquby. Published initial rental rates at crawl ran from 3.63% (2-year fixed, Green, with a heavy product fee) through mid-fee options at 4.63 to 4.89% to low-fee products at 5.73%, with HMO and multi-unit freehold block ranges from 3.74%. The follow-on rate is the trap: SVR plus 1.00% standard or plus 1.25% for HMO/MUFB, which meant 8.25 to 8.50% at crawl. The teaser-plus-fee mechanics mirror conventional BTL, so underwrite on total cost across the fixed period.
StrideUp: the flexible fintech
StrideUp's BTL purchase plan runs the same certified diminishing musharakah as its regulated HPP, audited by Amanah Advisors. Its envelope is the largest in the non-bank market: GBP 50,000 to GBP 2.5 million per property (GBP 3 million per portfolio), 80% FTV to GBP 1 million of value, HMOs up to 12 rooms and multi-unit blocks up to 10 units at 75% FTV, both doubled in 2026. Underwriting is the differentiator: SPVs with no minimum trading history, first-time landlords and first-time buyers accepted (income GBP 25,000, or GBP 30,000 in London and the South East), British expats eligible, top slicing lets personal income support lower-yielding properties, and gifted deposits can include interest-free intercompany loans. Product fee is 1 to 1.5% of financing. England only.
Offa: rent-only and 40-year terms
Offa's BTLPP solves the cash-flow rigidity that historically pushed Muslim landlords to conventional products: it offers a rent-only variant (the halal answer to interest-only) alongside rent-plus-acquisition, on terms up to 40 years, the longest in the certified market. Crawled rates ran roughly 6.24 to 6.60% by FTV band with a 1% product fee (minimum GBP 999). Affordability is tested on rental coverage, 125% for basic-rate taxpayers and companies, 140% for higher-rate taxpayers, with personal income top-ups allowed. Minimum income GBP 18,000, property values GBP 80,000 to GBP 5 million, individuals, limited companies and LLPs all accepted, England and Wales. Offa is candid that it holds legal ownership until buyout, secured by a lease, a Diminishing Partnership Agreement and a legal charge.
Nomo: the Gulf investor's option, with Scotland
Nomo Bank's rental property finance serves GCC-based investors, not UK residents, on commodity murabaha named in a signed fatwa dated March 19, 2025. Its published factsheet (dated August 2026) showed 2-year fixed at 5.51% and 5-year at 5.89% for standard facilities, improving to 5.46 to 5.79% above GBP 750,000, at 75% FTV with a 1% application fee and a 7.5% follow-on rate. Uniquely among these providers it finances Scottish rental property. Early exit economics are unusually fair: profit due for the remaining fixed period plus a GBP 240 settlement fee, with worked examples printed.
Pfida OwnToLet: the conscience option
Pfida's OwnToLet extends its no-debt partnership to landlords on a limited, case-by-case basis: co-ownership with market-based rent, no obligation to buy out Pfida's share, and a rental discount mechanic designed to be passed to tenants. Affordability is assessed on personal income rather than projected rent, deliberately, so payments survive void periods. Maximum finance GBP 400,000 on property values GBP 50,000 to GBP 500,000, UK-wide. It is a social-purpose product with rationed capacity, not a portfolio engine, and it is the only BTL option here built on partnership rather than a purchase-plan lease.
Choosing by landlord type
- UK-resident individual, first rental property: Gatehouse for published pricing and bank status; StrideUp if you are a first-time landlord or buying through a fresh SPV
- Portfolio builder using company structures: StrideUp's SPV terms and GBP 3 million portfolio ceiling, or Offa for rent-only cash flow
- HMO or multi-unit specialist: Gatehouse publishes rates; StrideUp takes up to 12 rooms with 2 years of landlord experience (1 year for HMO experience); Offa takes HMO on portfolio applications
- GCC-based investor: Nomo's grid is the pricing benchmark, and includes Scotland
- Values-first small landlord: Pfida, accepting the queue and the GBP 400,000 cap
- Larger commercial tickets and mixed-use: Habib Bank Zurich's Sirat window finances offices, student blocks and unlimited BTL portfolios at 65% FTV, with a choice of diminishing musharakah or commodity murabaha
Underwriting a halal BTL deal: the numbers that decide
Run the rental coverage test before you fall in love with a property. At Offa's published stress levels, a GBP 200,000 facility at roughly 6.4% needs about GBP 16,000 of rent to cover 125%, call it GBP 1,335 a month, and GBP 17,900 (GBP 1,495 a month) at the 140% higher-rate test. If local rents will not carry that, your options are a bigger deposit, top slicing with personal income where the provider allows it (StrideUp and Offa both do), or a different property. Then add the halal-specific line items: product fees of 1 to 1.5% of financing at StrideUp and 1% (minimum GBP 999) at Offa are proportional, not flat, so they scale painfully on large facilities; HMO valuations start at GBP 525 at StrideUp; and follow-on rates of 8.25 to 8.50% at Gatehouse make the end of the fixed period a scheduled event, not a surprise.
On voids: a purchase-plan landlord owes rent to the provider whether or not a tenant pays rent to them. Pfida's personal-affordability underwriting is built around exactly this risk, and it is a useful discipline even at providers that test rental coverage instead: hold a cash buffer of several months of payments per property, because the certified structure does not soften a missed payment any more than a conventional lender would.

The tax and structure homework
Two pieces of homework before any application. First, company versus personal ownership: the rental coverage stress differs (Offa tests companies at 125% versus 140% for higher-rate individuals), and the tax treatment of financing costs differs between individual and corporate landlords; take advice from an accountant who has seen Islamic BTL structures before. Second, the structure itself: Gatehouse, StrideUp and Offa run co-ownership models while Nomo runs commodity murabaha, a distinction that matters to some scholars and is explained in our structures guide.
