What a £250k Halal Mortgage Actually Costs Per Month in the UK (Worked Example)
A halal mortgage in the UK is a Home Purchase Plan (HPP) — you co-own the property with the bank and pay it rent on its share, not interest on a loan. For a £250,000 home with a 20% deposit (£50,000) on a 25-year plan, the all-in monthly payment at a realistic 2026 rental rate lands around £1,150–£1,200 a month — split between rent on the bank's share and an acquisition payment that buys you out over time. Below is the full step-by-step breakdown, including the fees and Stamp Duty most buyers don't budget for.
Rental rates are quoted per provider and reset with the Bank of England Bank Rate, which on the date of writing sits at 3.75% (held since December 2025; next Monetary Policy Committee decision 18 June 2026, per the Bank of England). The figures below use an illustrative 6.50% rental rate so you can follow the maths. Your actual rate, fees and eligibility come from a real provider quote — treat this as a model, not a personal offer.
How an HPP payment is built (rent + acquisition)
A UK halal mortgage uses Diminishing Musharaka (co-ownership) combined with Ijara (leasing). You and the bank buy the property as partners. Each month you pay two things bundled into one payment:
- The rent (Ijara) element — rent on the portion of the property the bank still owns. This is the bank's return, and it is the part people loosely compare to "interest" — but it is charged on the bank's ownership share, not on a debt you owe.
- The acquisition element — money that buys a slice of the bank's share, increasing your equity. As your share grows, the bank's share shrinks, so next month's rent is calculated on a smaller stake. This is why it is called diminishing Musharaka.
By the end of the term you own 100% and the rent has fallen to zero. Economically the cash flow looks a lot like a repayment mortgage; structurally and contractually it is ownership and rent, which is what makes it Shariah-compliant.
How the "rent" is benchmarked — and why it isn't interest
Providers don't pluck the rent from the air. They set a rental rate as the Bank of England Bank Rate (BBR) plus a fixed margin (for example "BBR + a margin" on a variable plan), or they fix the rental rate for an agreed period (2, 3 or 5 years) before it reverts to that variable rate. Al Rayan Bank, the largest UK provider, publishes exactly this structure — a fixed rental rate for the deal period, reverting to a variable rate set as BBR plus the bank's margin (see Al Rayan's HPP jargon buster).
The key distinction for Shariah purposes is what the payment is for. In a conventional mortgage, interest is the price of borrowed money (riba). In an HPP, the rent is the price of using an asset the bank actually owns a share of — a permissible commercial lease. The benchmark (BBR) is just a reference index to keep the rent competitive with the wider market; it does not turn the rent into interest, any more than a high-street landlord indexing rent to inflation makes that rent a loan.
Worked example: a £250,000 home, 20% deposit, 25-year HPP
Aisha, a first-time buyer in Birmingham, is buying a £250,000 house. She puts down a 20% deposit and takes a 25-year HPP with a UK Islamic bank.
Step 1 — The shares at completion
Deposit (Aisha's starting share): 20% × £250,000 = £50,000
Bank's starting share (the "finance" amount): 80% × £250,000 = £200,000
Finance-to-Value (FTV): 80%
Step 2 — The monthly payment
On a 25-year (300-month) plan at an illustrative 6.50% rental rate, the bank amortises Aisha's £200,000 acquisition over the term and charges rent on its declining share. The combined monthly payment works out to approximately £1,350 a month in month one.
• In the first month, roughly £1,083 is rent (6.50% ÷ 12 × £200,000) and about £267 is acquisition.
• By the final years, almost all of the £1,350 is acquisition and the rent has shrunk toward zero, because the bank's share has nearly vanished.
Step 3 — One-off costs at completion (see the fee and SDLT sections below)
Stamp Duty Land Tax: £0 for Aisha as a first-time buyer at £250,000 (relief covers up to £300,000).
Arrangement/product fee, valuation, legal: roughly £2,000–£3,500 combined (illustrative).
The headline: ~£1,350/month, of which ~£1,083 is "rent" in year one — falling every month as her ownership grows.
If you change the rental rate, the monthly payment moves the same way a conventional rate would. Here is how sensitive Aisha's £200,000 / 25-year plan is to the rental rate:
| Illustrative rental rate | Approx. monthly payment | Approx. rent in month 1 | Approx. acquisition in month 1 |
|---|---|---|---|
| 5.00% | ~£1,169 | ~£833 | ~£336 |
| 5.50% | ~£1,228 | ~£917 | ~£311 |
| 6.00% | ~£1,289 | ~£1,000 | ~£289 |
| 6.50% | ~£1,350 | ~£1,083 | ~£267 |
| 7.00% | ~£1,414 | ~£1,167 | ~£247 |
Illustrative only, calculated on a standard amortisation of the £200,000 acquisition over 300 months. Real HPP payment schedules vary by provider and by how the rent on the diminishing share is computed. Always work from a written provider quote.
Total cost over the full term vs a conventional repayment mortgage
Here is the comparison most people actually want: across the whole 25 years, does halal cost more? At the same rate, the answer is essentially no — the economics are near-identical because the cash flows mirror each other. The rent element of an HPP behaves like interest on a repayment mortgage, and the acquisition element behaves like the capital repayment.
| Over the full 25-year term | Halal HPP (rent + acquisition) | Conventional repayment mortgage |
|---|---|---|
| Property price | £250,000 | £250,000 |
| Deposit / starting equity | £50,000 (20%) | £50,000 (20%) |
| Amount financed | £200,000 (bank's share) | £200,000 (loan) |
| Rate basis | Rent benchmarked to BBR + margin | Interest benchmarked to BBR + margin |
| Monthly payment (illustrative 6.50%) | ~£1,350 | ~£1,350 |
| Approx. total paid over 25 years | ~£405,000 | ~£405,000 |
| What the "extra" ~£205,000 is | Rent for using the bank's share | Interest on borrowed money |
The numbers track each other because both products are pricing the same risk over the same term. The real-world differences are at the edges: HPP early-repayment rules (extra "acquisition payments" are often allowed a few set times a year — for example quarterly), the range of competing lenders (far fewer halal providers, so shop hard), and the rent-rate reset mechanics after a fixed period. The Shariah-compliant structure is what you are buying — not a cheaper or more expensive deal by default.
Where Stamp Duty sits — and why "double SDLT" was abolished
Here is the part that scared off a generation of Muslim buyers, and the reform that fixed it.
In a halal HPP the bank legally buys the property, then transfers ownership to you over the term. On a naive reading, that's two transfers — bank buys, then you buy from the bank — and so it looks like SDLT should be charged twice. For years that "double charge" was a genuine deterrent.
UK tax law fixed this through alternative property finance relief in the Finance Act 2003 (sections 71A, 72, 72A and 73). The relief means the intermediate transfers — the lease to you and the eventual transfer of the bank's reversion — are not charged to SDLT. The effect, in HMRC's own framing, is that the tax treatment is "the same as for a conventional mortgage product" (see HMRC's Stamp Duty Land Tax Manual, SDLTM28100). You pay SDLT once, on the purchase price of the property, exactly as a conventional buyer would.
So what SDLT does Aisha actually pay?
SDLT in England and Northern Ireland is charged in bands on the purchase price. For a standard (non-first-time, single-property) buyer of a £250,000 home, the calculation per gov.uk is:
| Band | Rate | SDLT on this slice |
|---|---|---|
| £0 – £125,000 | 0% | £0 |
| £125,001 – £250,000 | 2% | £2,500 |
| Total on £250,000 (standard buyer) | £2,500 |
But Aisha is a first-time buyer. First-time buyer relief means no SDLT up to £300,000, and a reduced 5% rate on the slice from £300,001 to £500,000, with relief lost entirely above £500,000 (gov.uk SDLT rates). Because her £250,000 purchase is under £300,000, Aisha pays £0 SDLT. A non-first-time buyer in the same house pays £2,500. Critically, the halal structure does not change this — the alternative property finance relief makes sure she is taxed once, as the real purchaser, and first-time buyer relief still applies to her.
SDLT bands and the first-time-buyer thresholds have changed several times in recent years and are sometimes adjusted at fiscal events (Budgets). Always confirm the current bands on gov.uk's SDLT rates page on the day you complete. Scotland (LBTT) and Wales (LTT) use entirely different systems and thresholds.
The fees that surprise halal buyers
The rental rate gets all the attention, but the one-off completion costs are where budgets slip. On an HPP they are largely the same categories as a conventional purchase — and thanks to the single-transaction SDLT treatment above, you don't pay extra duplicated legal or tax costs. Expect:
| Fee | What it is | Typical range (illustrative) |
|---|---|---|
| Arrangement / product fee | The provider's fee for setting up the HPP. Sometimes payable upfront, sometimes added to the finance. | £500 – £1,500 |
| Valuation fee | The bank's valuation of the property (separate from any survey you commission). | £0 – £600+ (scales with property value; sometimes free) |
| Legal / conveyancing fee | Conveyancing for a single transfer — the relief means there is no second, duplicated legal charge for the bank's purchase. | £800 – £2,000+ |
| Land Registry fee | Registering the title. | £20 – £500+ (scales with price) |
| SDLT (England/NI) | Paid once, on the purchase price. £0 here for a first-time buyer at £250,000. | £0 in this example |
The reassuring headline: because the double-transfer is relieved for both tax and (in practice) conveyancing, an HPP's upfront costs are broadly in line with a conventional mortgage. The fee that genuinely differs is the arrangement/product fee, which varies by provider — so get it itemised in writing and compare it across the (small) field of UK halal lenders.
- A UK halal mortgage is a Home Purchase Plan: you co-own with the bank (Diminishing Musharaka) and pay rent on its share plus an acquisition payment, not interest on a loan.
- On a £250k home, 20% deposit, 25-year plan at an illustrative 6.50% rental rate, expect roughly £1,350/month — about £1,083 rent and £267 acquisition in month one, with rent falling as your share grows.
- The rent is benchmarked to the Bank of England Bank Rate (3.75% as of writing) plus the provider's margin. The benchmark is a reference index — it does not make the rent into interest.
- At the same rate, total cost over 25 years is near-identical to a conventional repayment mortgage (~£405,000 paid). You are buying the Shariah-compliant structure, not a discount or a penalty.
- Double SDLT was abolished by alternative property finance relief (Finance Act 2003 ss 71A/72/72A/73). You pay SDLT once on the price — £0 here for a first-time buyer under £300,000, or £2,500 for a standard buyer at £250,000.
- Budget for the arrangement/product fee, valuation, conveyancing and Land Registry fee — but not for duplicated legal or tax charges, which the relief removes.
Is a halal mortgage more expensive than a normal mortgage?
At the same rate, no — the total cost over the term is essentially the same because the rent element mirrors interest and the acquisition element mirrors capital repayment. The practical risk is fewer providers, so the margin you are offered may be a little higher or lower than the conventional market; shop the small field of UK Islamic banks and brokers carefully.
Do I pay Stamp Duty twice on a halal HPP?
No. Although the bank legally buys the property and then transfers it to you, alternative property finance relief in the Finance Act 2003 (sections 71A, 72, 72A and 73) exempts those intermediate transfers from SDLT. You pay Stamp Duty once, on the purchase price, exactly as a conventional buyer would. See HMRC's SDLT Manual, SDLTM28100.
What SDLT would I pay on a £250,000 home?
For a standard buyer in England or Northern Ireland it is £2,500 (0% on the first £125,000, 2% on the next £125,000). A first-time buyer pays £0, because first-time buyer relief means no SDLT up to £300,000. Confirm the current bands on gov.uk before completing, as they change at fiscal events. Scotland and Wales use different systems (LBTT and LTT).
How is the "rent" on a halal mortgage calculated?
Providers set a rental rate as the Bank of England Bank Rate plus a fixed margin, or fix it for a period (e.g. 2, 3 or 5 years) before it reverts to that variable rate. The rent each month is charged on the bank's remaining ownership share, so as you buy more of the property the rent falls. The Bank Rate is just a benchmark to keep the rent market-competitive.
Can I overpay or pay off a halal mortgage early?
Usually yes, via additional acquisition payments that buy more of the bank's share. Providers often allow these at set times (for example a few times a year on fixed-rate plans) and full early settlement is permitted under defined terms. Check your specific plan's rules — they differ between fixed and variable rental rates.
What deposit do I need for a halal mortgage in the UK?
Most UK Home Purchase Plans require a deposit (your starting share) — historically often around 20%, though some products and schemes have allowed less. The bank's share is your Finance-to-Value (FTV); an 80% FTV means a 20% deposit. A larger deposit lowers both your monthly rent and your overall cost. Always confirm minimums with the specific provider.
