Islamic business finance in the UK: a practical guide

For UK Muslim business owners who want their borrowing to align with Sharia principles, the conventional SME loan and credit card market is structurally off-limits because of the interest (riba) charged. Islamic finance offers a parallel set of products that achieve the same commercial outcome — capital for a business purpose — through different legal structures. The UK has had Sharia-compliant retail banking for over two decades, and the commercial offer has developed alongside it. This guide explains what is genuinely available, who it tends to suit, and the eligibility signals UK Islamic banks look at.

The core Islamic finance structures

Murabaha (cost-plus sale)

In a murabaha, the bank buys an asset (a vehicle, piece of equipment, commercial property) and immediately sells it to the customer at an agreed marked-up price, payable in instalments. The mark-up is fixed at the outset and is not interest — it is a disclosed profit on the sale. The customer ends up with the asset and a fixed payment schedule. Murabaha is the most common structure for UK Islamic asset finance and commercial property purchase.

Ijara (lease)

In an ijara, the bank buys the asset and leases it to the customer for a defined term. The customer pays rent. At the end of the lease, ownership transfers to the customer (ijara wa iqtina) or the asset reverts to the bank (operating ijara). Ijara is widely used for vehicles, equipment and commercial property where the customer wants the use of the asset without immediate ownership.

Musharaka (partnership)

Musharaka is a partnership structure where the bank and the customer jointly invest in a venture or asset and share profits and losses according to an agreed ratio. It is used less often in routine UK commercial finance because of the operational complexity but appears in property investment, project finance and Islamic working capital structures.

Mudaraba and wakala (investment management structures)

These structures are more common in Islamic deposit and investment products than in commercial lending. A mudaraba is a profit-sharing arrangement where one party provides capital and the other provides expertise. Wakala is an agency arrangement. UK SMEs are unlikely to encounter these directly when seeking business finance but may see them in Islamic savings or investment accounts.

UK providers of Islamic business finance

• Gatehouse Bank — Sharia-compliant commercial property finance, residential BTL and savings products.

What you can finance

• Commercial property — owner-occupier or investment, typically structured as murabaha or diminishing musharaka.
• Buy-to-let property under Sharia structures, including HMO and small portfolio purchase.
• Vehicles and equipment via murabaha or ijara.
• Working capital via Sharia-compliant trade finance and asset-backed structures.
• Refinancing of existing conventional debt into a Sharia-compliant facility, subject to scholar approval of the rationale.

What you cannot finance

Islamic banks apply sector exclusions on top of standard commercial criteria. Common exclusions include:

• Alcohol, pork production or distribution, gambling, conventional financial services that earn interest.
• Adult entertainment, tobacco and arms-related industries.
• Speculative trading, conventional insurance underwriting, and any activity inconsistent with Sharia principles.
• Some banks also exclude leisure venues with high alcohol revenue exposure.

How pricing compares

UK Islamic finance pricing is broadly competitive with conventional finance, expressed as a fixed mark-up or rental rate rather than an interest rate. For commercial property, ranges of 6 to 9 per cent are typical depending on LTV, term and asset type. For asset finance, rates sit alongside conventional providers. Working capital is more constrained: there is no true Sharia-compliant equivalent of an unsecured business loan, so options here are narrower and typically structured around an underlying asset or trade transaction.

Eligibility signals UK Islamic banks look at

1. Trading history — typically 2 years for commercial property, 1 year for asset finance.
2. Profitability and affordability on a fixed-rental basis (the equivalent of DSCR).
3. Director credit and any prior bankruptcy or IVA.
4. Sector compliance with Sharia principles.
5. Deposit or contribution to the asset purchase — typically 20 to 35 per cent on property.
6. Clean source of deposit funds (relevant for AML and source-of-wealth checks).

When Islamic finance might not be the right route

Sharia-compliant working capital is genuinely limited in the UK. A B2B services business needing a £100,000 unsecured cashflow line will struggle to find a true Sharia-compliant equivalent — there is no Islamic version of an iwoca or Funding Circle loan at the time of writing. Qardus has built a Sharia-compliant SME finance product for asset-backed and trade transactions, but pure unsecured working capital remains rare. Owners with this need sometimes structure the requirement around an underlying asset purchase to make it financeable.

Documentation and process

The document pack is largely the same as for conventional finance — accounts, bank statements, VAT returns, director ID — but with two additions: a clearer description of the business activity to confirm Sharia compatibility, and detail on the source of any deposit funds. Underwriting timelines are comparable to conventional commercial property lenders: 4 to 10 weeks for a commercial mortgage, faster for asset finance.

A note on terminology

You will sometimes see Islamic finance described in conventional terms ("Islamic loan", "Islamic mortgage"). These phrases are widely used colloquially but technically there is no loan or mortgage involved — the structure is a sale and instalment plan, or a lease, or a partnership. Understanding the underlying structure helps in conversations with lenders and with your accountant on the tax treatment.
