Al Rayan vs Gatehouse Bank (2026): Britain's Two Islamic Heavyweights Compared

Ask which UK Islamic bank to use and the answer usually resolves to two names. Al Rayan Bank, founded 2004, Britain's first and largest wholly Islamic bank, now a focused deposit house after closing retail current accounts and home purchase plans to new customers. And Gatehouse Bank, the retail standard-bearer, with the market's most accessible savings shelf and its only published Islamic home finance rate card. They compete directly on savings and almost nowhere else, which makes the comparison unusually clean. All figures verified August 6, 2026.

The savings head-to-head

The pattern is unmistakable. Al Rayan wins raw taxable fixed rates at every term where both publish; Gatehouse wins accessibility, flexibility and tax efficiency. And the tax point flips more outcomes than savers expect: for anyone whose Personal Savings Allowance is already consumed, Gatehouse's 4.35% tax-free one-year ISA beats Al Rayan's 4.73% taxable fix after tax at every taxpayer band, per the arithmetic in our halal ISA guide. Rate-chasers with unused allowance take Al Rayan; taxpayers with used allowance take Gatehouse; and savers under 10,000 GBP take Gatehouse because Al Rayan's shelf is closed to them in practice. One curiosity on Al Rayan's own curve deserves a note: its three-year deposit paid more than its two-year at our verification (4.55% against 4.43%), so anyone locking beyond a year at Al Rayan should price the longer term rather than assuming the usual downward slope.

Shariah governance: two strong answers, different shapes

Both banks run wholly Islamic balance sheets with named three-scholar boards, and one scholar, Sheikh Dr Nizam Yaquby, sits on both. Al Rayan's Sharia Supervisory Committee (Sheikh Dr. Waleed Bin Hadi chairing, with Sheikh Dr. Nizam Yaqoobi and Mufti Abdul Qadir Barkatullah) publishes scanned fatwa certificates per product plus a signed annual report confirming profit allocations and charity donation of non-compliant earnings. Gatehouse's board (Yaquby chairing since March 2015, with Sheikh Dr Esam Khalaf Al Enezi and Sheikh Dr Abdul Aziz Al-Qassar) publishes biographies and downloadable certificates per product family, and its savings pages carry the market's clearest fallback commitment: an exit offer if expected rates ever could not be delivered. Honest nitpicks each way: Al Rayan's certificates are image scans, some predating current product issues; Gatehouse names no deposit contract on its savings pages. Neither nitpick should move a mainstream saver.

Beyond savings: they stop competing

Home finance: Gatehouse, effectively unopposed between the two. Its Home Purchase Plan publishes full rates (5.53% to 6.78%), takes 5% deposits, runs diminishing Musharaka, and covers UK residents, expats and international buyers, plus the only published Islamic BTL ranges in Britain including HMOs. Al Rayan's retail HPP is closed; what remains is negotiated Premier Home Finance for HNW and non-resident clients on a Tawarruq structure with no published pricing. Current accounts: neither; that market now belongs to HBZ Sirat and the apps, per our current accounts guide. Commercial property: Al Rayan, at scale, with 2.5m to 32m GBP tickets and over 2 billion GBP written in FY2025. Treasury deposits: Al Rayan's named-contract Wakala product from 250,000 GBP.

A worked example: 30,000 GBP, two ways

Take a household with 30,000 GBP of savings, a used-up Personal Savings Allowance and a five-year horizon. The Al Rayan-first construction: 10,000 GBP in the Everyday Saver at 2.75% for access, 20,000 GBP in the one-year fix at 4.73%, rolling annually; simple, strong headline rates, but every pound of profit is taxed, and the access layer demands the full 10,000 GBP minimum to earn anything. The Gatehouse-first construction: 5,000 GBP in easy access at 2.95% (only what access genuinely requires, since the minimum is 1 GBP), the year's ISA allowance into the one-year Woodland Cash ISA at 4.35% tax-free, and the remainder in a taxable fix, at Gatehouse for simplicity or at Al Rayan for the higher rate. For a basic-rate taxpayer the second construction wins on after-tax profit in most years, because the tax-free 4.35% out-earns the taxed 4.73% on every ISA-sheltered pound. The general lesson: Al Rayan sets the headline, Gatehouse sets the structure, and structure usually pays more than headlines.

Operational feel

Both are app-and-online banks for savers; neither opens branches to you. Al Rayan runs everything through nominated external accounts via its digital banking, with profit paid monthly on the Everyday Saver and quarterly or at maturity on fixes. Gatehouse runs the Savings App with the same nominated-account model, and plants a tree in certified UK woodland for every fixed term opened or renewed under its UN Principles for Responsible Banking membership. Scale and backing differ in flavour, not adequacy: Al Rayan has Qatari institutional ownership (Masraf Al Rayan), total assets past 3 billion GBP and record FY2025 profits; Gatehouse is smaller but growing on the strength of the retail franchise. Both are PRA-authorised with FSCS protection to 120,000 GBP on separate licences, which is the quiet win of holding both: 240,000 GBP of protected halal savings across the pair, per our FSCS guide.

The verdict, by saver

• Starting out or under 10,000 GBP: Gatehouse, no contest; 1 GBP opens the door.
• Lump-sum rate-chaser with unused tax allowance: Al Rayan's 4.73% one-year fix, though check HBZ Sirat's 4.81% first.
• Taxpayer with used allowance: Gatehouse's Cash ISA shelf, unopposed.
• Emergency fund: Gatehouse easy access at 2.95% from 1 GBP.
• Home buyer: Gatehouse, published rates and 5% deposits.
• Treasurer or charity with 250,000 GBP+: Al Rayan's Wakala Treasury Deposit.
• Most households: genuinely both, one for the ISA and easy access, the other for fixed term lumps.

Frequently asked questions

Which bank is more Shariah compliant?

Both publish named boards, annual reports and product certificates; a shared scholar links the two boards. Al Rayan offers more per-product fatwa paperwork; Gatehouse offers clearer structural naming on home finance (diminishing Musharaka) and the exit commitment on savings. We find no basis to rank one above the other on compliance; rank them on fit instead.

Which is safer?

Both are PRA-authorised UK banks with FSCS protection to 120,000 GBP. Al Rayan brings two decades of history and Qatari backing; Gatehouse brings a UN-aligned, retail-funded model. FSCS makes the deposit-safety question identical for balances within limits, and holding both doubles your protected total.

Can I open accounts at both in the same week?

Nothing prevents it: separate applications, separate nominated-account setups, and you are done. Start with the account that matches your next pound of savings, and use our savings comparison or get matched to sequence the rest.
