The Muslim business owner searching for halal business banking in Britain meets a market even thinner than the personal one, and far worse documented. Comparison sites list nothing; the banks' business pages assume you already know them. Our database, verified August 6, 2026, shows a real but narrow field: one bank still opening Islamic business current accounts, a serious treasury shelf for cash-rich firms and charities, two strong property finance desks, and honest gaps everywhere else. Here is the map.

The business current account: one door
HBZ Sirat is effectively the only UK bank opening branch-based Islamic current accounts to new business customers: sole traders, partnerships, companies and SPVs, including the trading businesses, shops, wholesalers, import-export firms, that need cash handling and a banker who knows them. Eight branches across London, Manchester, Leicester and Birmingham, FSCS protection to 120,000 GBP on eligible deposits, governance under AAOIFI standards with IFAAS external audit. The account pays no profit, correctly, and the tariff is not published, so request it in writing during onboarding. The window structure (Sirat sits inside conventional Habib Bank Zurich) is the one values question to settle first, and our window analysis gives it a fair hearing. For businesses that cannot accept a window, the honest answer is that no wholly Islamic UK bank currently opens business current accounts, and the workarounds (e-money accounts, conventional plumbing with purification) carry their own compromises.
Where business cash earns: the treasury shelf
| Product | Minimum | Rate | Notes |
|---|---|---|---|
| Al Rayan business fixed terms | 100,000 GBP | Business rates on the FTD shelf (retail: 4.73% at 1y) | Wholly Islamic bank; per-product fatwa certificates |
| Al Rayan Wakala Treasury Deposit | 250,000 GBP | Negotiated per deposit | Named Wakala contract with dedicated certificate; built for treasurers and charities |
| HBZ Sirat business Wakala deposits | 10,000 GBP | Negotiated from branch | GBP/USD/EUR; one-month terms available, rare in the market |
| BLME Premier Deposit | 1,000 GBP (to 1m GBP) | Up to 4.65% headline | Correspondence servicing; terms to 7 years |
Three tiers emerge. An SME with 10,000 to 100,000 GBP of reserves negotiates a Wakala rate at a Sirat branch, in sterling or dollars, at terms as short as one month, flexibility no digital provider matches. A company or charity with 100,000 GBP+ takes Al Rayan's business fixed terms on a wholly Islamic balance sheet with published fatwa certificates. And a treasurer placing 250,000 GBP+ negotiates Al Rayan's named-contract Wakala Treasury Deposit, the most explicitly documented Islamic treasury product in Britain. Our standing tender advice applies with extra force at these sizes: make all three quote, in writing, against each other; the basis points at stake are real money at treasury scale.
Financing: property strong, working capital thin
Business financing in UK Islamic banking means, overwhelmingly, property. Al Rayan's Commercial Property Finance desk writes 2.5 million to 32 million GBP tickets, wrote over 2 billion GBP gross in FY2025, and drove the bank's record results; it traces to the bank's 2006 launch of Diminishing Musharakah with Ijara, and pricing is negotiated per case with no early settlement fees. HBZ Sirat's Income Generating Property Finance serves the mid-market the giants skip: BTL portfolios with no size cap, HMOs, offices, retail, warehouses and student blocks at up to 65% FTV over terms to five years, with a choice of Diminishing Musharaka or Commodity Murabaha, from a 35% deposit. Gatehouse publishes corporate BTL ranges including SPV and HMO products no one else prints. What the licensed market lacks is everyday working capital: no Islamic overdrafts, invoice finance or unsecured business lending appears anywhere in our verified data from these banks; specialist providers cover parts of that gap through our business financing hub, and pretending the banks fill it would misdirect you. The practical consequence for a growing firm: plan working capital around cash discipline and the deposit shelf, keeping a term-laddered reserve at the banks above rather than assuming an Islamic credit line will appear when needed, because on the verified evidence, it will not.
Governance evidence for boards and trustees
Business customers carry a documentation burden personal savers do not: directors and trustees must be able to show why a banking arrangement satisfies the organisation's Islamic commitments. The market's paper trail maps neatly onto that need. Al Rayan provides the strongest file: named three-scholar committee, a dedicated downloadable fatwa certificate for the Wakala Treasury Deposit, and a signed annual Shariah report in the accounts confirming profit allocations. Sirat provides AAOIFI-standard governance with IFAAS external audit and published window certificates, plus the FY2024 accounts confirming the Islamic financing structures, sufficient for most boards, though without named scholars. BLME publishes its board, an annual compliance certificate and a Zakat Statement. File the relevant certificates with the board minutes at the point of placement, and re-verify at renewal; governance that is documented once a year is governance that survives an audit or an AGM question.
The FSCS dimension belongs in the same file: note which licence each placement sits under, the eligibility basis for your entity, and the spread policy across licences, so the protection position is a decision on record rather than an accident of whoever opened the accounts.
The setup, by business size
- Sole trader or micro business: Sirat current account for banking; surplus into Gatehouse (from 1 GBP) or BLME (from 1,000 GBP) under the owner's structure as advised by your accountant.
- Trading SME: Sirat current account and branch relationship; reserves in negotiated Sirat Wakala terms; property via Sirat's or Gatehouse's published ranges.
- Cash-rich company or charity: tender Al Rayan business FTDs and the Wakala Treasury Deposit against Sirat and BLME; mind the 120,000 GBP FSCS limit per licence and spread accordingly.
- Property business: Gatehouse's published corporate BTL for standard assets; Sirat for HMOs and mixed portfolios; Al Rayan for 2.5m GBP+ commercial tickets.
Frequently asked questions
Does FSCS protect business deposits?
Eligible business deposits at PRA-authorised banks carry FSCS protection, with eligibility depending on the entity's status under the scheme's rules; the 120,000 GBP per-licence limit applies as it does personally. Treasurers holding beyond the limit at one bank should spread across licences, exactly as our FSCS guide describes for households, with the scheme's business eligibility rules checked per entity.
Can I run my business on Algbra or Kestrl?
Neither app is positioned as a business banking product in our verified data, and safeguarded e-money without FSCS cover is a poor home for business funds in any case. The business answer today is Sirat, with the conventional-plumbing workaround as fallback for businesses that cannot meet its onboarding.

What should a mosque or charity do with reserves?
Al Rayan's Wakala Treasury Deposit was built for exactly this customer at 250,000 GBP+, with a dedicated fatwa certificate for trustees to file; below that, its 100,000 GBP business fixed terms and Sirat's negotiated deposits cover the range. Trustees should document the Shariah basis (certificates are downloadable) and the FSCS position per licence as part of their reserves policy, and get matched if the sums or structures get complicated.
