One of the most common questions we hear from Muslim homebuyers is: "Is a halal mortgage more expensive than a conventional one?" The honest answer is: sometimes yes, sometimes no — and it depends on factors that most comparison sites don't explain clearly.
In this guide, we'll compare the true cost of halal and conventional mortgages side by side, with real numbers, so you can make an informed decision.
Key finding: Halal mortgages have historically carried a small premium over conventional products, but this gap has narrowed significantly in 2024–2025 as more providers have entered the market and competition has increased.
To understand why the costs can differ, you first need to understand the structural difference between the two products.
A conventional mortgage is a loan — you borrow money from a bank and repay it with interest. A halal mortgage (typically structured as Diminishing Musharaka or Ijara) avoids interest by creating a co-ownership or lease arrangement. The bank's profit comes from a rental charge or profit rate rather than interest.
In practice, the monthly payments look similar — but the underlying mechanics, fee structures, and total repayment amounts can differ.
Based on a £300,000 property with a £60,000 (20%) deposit — a £240,000 finance amount over 25 years:
| Factor | Halal Mortgage | Conventional Mortgage |
|---|---|---|
| Profit/Interest Rate | ~5.8–6.5% | ~4.8–5.5% |
| Monthly Payment (est.) | ~£1,580–£1,680 | ~£1,450–£1,550 |
| Arrangement Fee | £999–£1,999 | £999–£1,999 |
| Early Repayment Charges | Varies by provider | Varies by lender |
| Stamp Duty (UK) | Potential double charge* | Standard rate |
| Total 25yr repayment (est.) | ~£474,000–£504,000 | ~£435,000–£465,000 |
*The UK government introduced Stamp Duty Land Tax (SDLT) relief for Islamic mortgages in 2003, eliminating the double-charge issue for most structured products. Always confirm with your provider.
The profit rate on halal mortgages is typically slightly higher than conventional interest rates for several reasons:
In 2025, the halal mortgage market in both the UK and USA is more competitive than ever. Al Rayan Bank, Gatehouse Bank, and Ahli United in the UK — alongside Guidance Residential and UIF in the USA — have all reduced their profit rates as competition has intensified.
For some products, particularly for buyers with large deposits and strong credit profiles, the rate difference is now less than 0.5%. Over a 25-year term, this translates to a relatively small total difference that many buyers consider worthwhile for the peace of mind of Sharia compliance.
A purely numerical comparison misses an important dimension. For Muslim buyers, the cost of a conventional mortgage isn't just financial — there's a religious and ethical dimension that has real value. Many buyers find that the slight cost premium is a reasonable price for:
Halal mortgages in 2025 are more affordable than they have ever been, and the gap with conventional rates continues to narrow. For Muslim homebuyers, the small remaining premium is increasingly viewed as acceptable — particularly given the significant personal and religious value of avoiding interest. We recommend getting quotes from at least three Sharia-compliant providers and comparing them against conventional products before making a decision.
