Islamic Mortgages: How Sharia-Compliant Home Finance Works

For buyers who want to avoid paying or receiving interest (riba), a conventional mortgage isn't an option. Instead, UK banks offer Sharia-compliant Home Purchase Plans (HPPs) — regulated by the Financial Conduct Authority and designed to achieve home ownership without interest. The legal work behind them is a little different, and it helps to understand why.

The Three Main Structures

Almost all UK Islamic home finance falls into one of three models:

• Diminishing Musharaka (co-ownership) — the most common for residential buyers. You and the bank jointly own the property. You pay rent on the bank's share and gradually buy that share out, until you own 100%.
• Ijara (lease-to-own) — the bank buys the property and leases it to you, with payments that build towards ownership over time. More common for buy-to-let or commercial use.
• Murabaha (cost-plus sale) — the bank buys the property and sells it to you at an agreed marked-up price payable in instalments, with ownership passing immediately. Rarely used for residential homes.

Stamp Duty: No Double Charge

A common worry is that, because the bank buys the property first, Stamp Duty might be charged twice. It isn't. Since the Finance Act 2003 (sections 71A and 73), Sharia-compliant HPPs are specifically relieved from the second SDLT charge. You pay Stamp Duty once, at the same rates as a conventional buyer — including the usual surcharges where they apply, such as on second homes.

Why the Conveyancing Is Different

The legal process is more involved than a standard purchase because of the ownership structure:

• There are usually two linked agreements — one governing the joint purchase, and one governing your gradual acquisition of the bank's share.
• The Land Registry position reflects the co-ownership arrangement, moving towards sole ownership over the life of the plan.
• The documents need a solicitor who understands how these products are put together, so that your rights and obligations are properly explained before you commit.

Deposit requirements tend to be higher than a typical conventional deal — often around 20%, though some products allow less — and the "rental rate" performs a similar role to an interest rate when comparing costs.
