Halal Buy-to-Let in the UK: Rental Yield Worked Example on a £180k Flat
A halal buy-to-let in the UK works through a Buy-to-Let Home Purchase Plan (BTL HPP) — a co-ownership and lease structure offered by Al Rayan Bank and Gatehouse Bank instead of an interest-bearing mortgage. On a £180,000 flat with a 25% deposit, our worked example below shows a roughly 5.8% gross yield falling to about 2.6% net after the HPP rent and running costs — and, crucially, HMRC taxes the HPP “rent” as if it were interest, so the same Section 24 restriction that hits conventional landlords hits you too.
How a buy-to-let Home Purchase Plan actually works
There is no Shariah-compliant “mortgage” in the conventional sense, because charging or paying riba (interest) is prohibited. Instead, UK Islamic banks use a Home Purchase Plan (HPP) — for investment property, a Buy-to-Let HPP. Two structures dominate the UK market:
- Diminishing Musharaka (co-ownership) + Ijara (lease). You and the bank buy the property as joint owners. You put in your deposit as your share; the bank funds the rest. Each month you pay two things bundled into one payment: an acquisition payment that buys another slice of the bank’s share, and a rent payment on the share the bank still owns. As your ownership rises, the bank’s share — and therefore the rent — falls. At the end of the term you own 100%.
- Ijara-only (rent-only). Some plans have no acquisition element — you simply rent the bank’s share for the term and buy it out (or sell) at the end. This keeps monthly payments lower but you build no equity along the way, so it is less common for long-term landlords.
The Diminishing Musharaka + Ijara model is what Al Rayan Bank uses for its Buy-to-Let Home Finance, and Gatehouse Bank offers a comparable BTL HPP range. As of 2026 these two are the principal high-street Islamic providers of BTL HPPs in the UK (with smaller specialists such as StrideUp focused mainly on residential HPPs).
Which UK providers offer BTL HPPs
| Provider | BTL structure | Typical deposit (Finance-to-Value) |
|---|---|---|
| Al Rayan Bank | Diminishing Musharaka + Ijara | ~25–30% deposit (FTV typically capped around 70–75%) |
| Gatehouse Bank | Diminishing Musharaka + Ijara (BTL HPP range) | ~25%+ deposit; rates reviewed periodically across the BTL range |
| StrideUp | Co-ownership HPP (mainly residential) | From low deposits on residential; BTL availability limited |
These figures move with each provider’s product range — always confirm the current FTV cap, rental rate and fees directly with the bank or a specialist Islamic finance broker before you commit. Check the source pages: Al Rayan Bank home finance and Gatehouse Bank.
Aisha, a higher-rate taxpayer in Birmingham, buys a £180,000 one-bed flat as a buy-to-let through a Diminishing Musharaka BTL HPP. She puts down a 25% deposit (£45,000); the bank co-owns the remaining £135,000 (75% FTV). The flat lets for £875 per month.
Step 1 — gross rental yield. Annual rent = £875 × 12 = £10,500. Gross yield = £10,500 ÷ £180,000 = 5.83%.
Step 2 — the HPP ‘rent’ cost. Suppose the bank charges an Ijara rental rate of 6.5% on its £135,000 share in year 1. Rent to the bank ≈ £135,000 × 6.5% = £8,775/yr (£731/mo). (Her full monthly HPP payment is higher because it also includes acquisition payments buying down the bank’s share — but only the rent portion is a finance cost; the acquisition portion is buying an asset, not an expense.)
Step 3 — running costs. Letting/management 10% of rent (£1,050), insurance (£200), repairs & maintenance allowance (£600), and an annual service charge/ground rent on a flat (£1,200) = £3,050.
Step 4 — net cash yield before tax. £10,500 rent − £8,775 HPP rent − £3,050 costs = −£1,325. On these assumptions Aisha is slightly cash-flow negative. If instead the property were owned outright (no HPP), net would be £10,500 − £3,050 = £7,450, a net yield of ~4.1% on the £180k. The HPP rent is the single biggest drag — exactly as a conventional mortgage would be.
Re-run with a lower rental rate (5.0%): bank rent ≈ £6,750; net = £10,500 − £6,750 − £3,050 = +£700/yr, a thin but positive ~2.6% net yield on her £45,000 deposit equity it is ~+1.6%. The lesson: at today’s rental rates, a 25%-deposit BTL HPP on a low-yielding flat is finely balanced — the numbers only work with a strong gross yield, a competitive Ijara rate, or a bigger deposit.
Gross vs net yield — the headline numbers
| Line | Amount (year 1) |
|---|---|
| Purchase price | £180,000 |
| Deposit (your share, 25%) | £45,000 |
| Bank’s share (75% FTV) | £135,000 |
| Annual rent received | £10,500 |
| Gross yield | 5.83% |
| HPP rent paid to bank (6.5% on bank share) | −£8,775 |
| Running costs (mgmt, insurance, repairs, service charge) | −£3,050 |
| Net cash flow before tax | −£1,325 |
| Net yield on purchase price (after costs, excl. acquisition payments) | −0.7% |
Yield is illustrative only; rental rates, fees and local rents vary. The point is the method: gross yield = annual rent ÷ price; net yield subtracts the bank’s rent and your running costs but not the acquisition payments (those buy equity, they aren’t an expense). Don’t forget the one-off costs on day one — Stamp Duty (below) and arrangement/valuation fees — which dilute your true return on capital.
Rental cover and the stress test on BTL HPPs
Islamic BTL providers assess affordability the same way conventional BTL lenders do — on rental cover, not your salary. The rent the property earns must comfortably exceed the rent you owe the bank, tested at a higher “stress” rate so the deal still works if rental rates rise.
- Rental cover ratio (often called ICR by analogy): typically the expected rent must be 125%–145% of the bank’s rent payment, with the higher end applied to higher-rate taxpayers and limited-company borrowers.
- Stress rate: the bank calculates that cover using a notional rental rate often 1–2 percentage points above the actual rate (or a regulatory floor), so a deal that only just balances at today’s rate will fail the test.
Aisha’s bank stress-tests at a 7.5% notional rental rate and requires 145% cover (she’s a higher-rate taxpayer). Stressed bank rent = £135,000 × 7.5% = £10,125/yr. Required rent for 145% cover = £10,125 × 1.45 = £14,681/yr (£1,223/mo). Her actual rent of £875/mo (£10,500/yr) fails — she would need a larger deposit (lower bank share), a higher-renting property, or a lower-cover lender. This is the most common reason a 25%-deposit BTL HPP gets declined on a low-yield flat.
Tax: Section 24 and how HMRC treats the HPP ‘rent’
This is the part most halal-finance guides get wrong. Because Islamic finance avoids interest, you might assume the Section 24 mortgage-interest restriction doesn’t apply. It does. Under Part 10A of the Income Tax Act 2007, “alternative finance return” — the rent element of your HPP — is treated as if it were interest for income tax. HMRC’s own manual states “ITA07/S564M provides that… alternative finance return is treated as if it were interest” (SAIM2250).
So an individual landlord on a BTL HPP gets the same treatment as a conventional landlord:
- You cannot deduct the HPP rent from your rental income to reduce taxable profit.
- Instead you get a basic-rate (20%) tax reduction — calculated as 20% of the lowest of: the finance costs, the property profits, or your adjusted total income above the Personal Allowance (gov.uk: tax relief for residential landlords).
- For a higher-rate (40%) taxpayer this is a real cost: you’re taxed on rent that you never really kept, and only get relief back at 20%.
Take Aisha’s lower-rate-rent scenario where HPP rent is £6,750 and net-of-other-costs profit before finance is £7,450. As a higher-rate taxpayer:
Old (pre-2017) way: deduct £6,750 rent → taxable profit £700 → tax at 40% = £280.
Section 24 way (now): taxable profit = £7,450 (rent NOT deducted) → tax at 40% = £2,980, minus a 20% tax reducer on the £6,750 finance cost = −£1,350 → tax due £1,630.
Same property, same cash — but Section 24 costs Aisha £1,350 more tax than the old rules, because her HPP rent only attracts 20% relief while she pays 40% on the headline profit. The HPP being Shariah-compliant changes nothing about this.
2026–27 income tax bands used above (England, Wales & NI; Scotland differs) — Personal Allowance £12,570; basic rate 20% to £50,270; higher rate 40% to £125,140; additional rate 45% above (gov.uk: income tax rates).
Other tax points for BTL HPP landlords:
- Stamp Duty Land Tax (England & NI): a buy-to-let is an additional dwelling, so you pay the standard residential SDLT rates plus a 5% surcharge on the whole price. On £180,000 that surcharge alone is £9,000 (gov.uk: SDLT residential rates). Wales (LTT) and Scotland (LBTT) have their own surcharges.
- Replacement of Domestic Items relief: the old 10% wear-and-tear allowance was abolished in April 2016. You can now only deduct the cost of replacing furnishings/appliances, not buying them first time (gov.uk: working out rental income).
- £1,000 property allowance: small landlords can take a £1,000 tax-free property allowance instead of deducting actual expenses — rarely worth it once you have HPP rent and costs (gov.uk).
Limited company / SPV BTL and the Shariah angle
Many UK landlords now buy through a limited company (a Special Purpose Vehicle, SPV) precisely because companies are not subject to Section 24 — a company deducts its finance costs (including HPP rent) in full against profits before paying Corporation Tax. For a higher-rate taxpayer building a portfolio, an SPV can materially improve net return.
From an Islamic-finance perspective, an SPV BTL HPP is generally acceptable provided the underlying structure stays Shariah-compliant:
- The finance itself must be a genuine HPP (Musharaka/Ijara), not a conventional company mortgage relabelled.
- The SPV’s activity — residential letting — must be halal; avoid lettings to non-permissible businesses (e.g. a bar, gambling premises, conventional bank branch) where you have a choice.
- Any cash the SPV holds should sit in a Shariah-compliant account, not an interest-bearing one; interest received would need to be purified (given to charity).
- Both Al Rayan and Gatehouse can finance corporate/SPV BTL applicants — confirm the bank lends to your specific company structure before incorporating.
Weigh the SPV tax saving against extra running costs (accountancy, company filings) and slightly higher finance rates that BTL providers often apply to limited companies. For most single-property landlords the savings are modest; for portfolio landlords they compound. This is a decision to take with a qualified accountant and a scholar-supervised provider, not from a worked example alone.
- Halal buy-to-let in the UK runs through a BTL Home Purchase Plan (Diminishing Musharaka + Ijara) from Al Rayan Bank or Gatehouse Bank — not an interest mortgage.
- On a £180k flat with 25% deposit, expect a ~5.8% gross yield that the HPP rent and costs can erode to break-even or thin positive — the deal hinges on the rental rate and your deposit size.
- Providers stress-test on rental cover (125–145%) at a notional rate 1–2 points above the real one; low-yield flats often fail.
- HMRC treats the HPP ‘rent’ as if it were interest (Part 10A ITA 2007, s.564M), so Section 24 caps your relief at the 20% basic rate — a real extra cost for 40% taxpayers.
- Add the 5% SDLT surcharge on the purchase, and consider a Shariah-compliant SPV to escape Section 24 — with an accountant and scholar-supervised finance.
Is a buy-to-let Home Purchase Plan actually halal?
Yes, when provided by a scholar-supervised Islamic bank such as Al Rayan or Gatehouse. The structure is co-ownership (Diminishing Musharaka) plus a lease (Ijara): you and the bank own the property together and you pay rent on the bank’s share rather than interest on a loan. Each provider has a Shariah Supervisory Board that certifies the contracts. Always check the product is a genuine HPP and not a conventional mortgage relabelled.
If there’s no interest, does Section 24 still apply to me?
Yes. Under Part 10A of the Income Tax Act 2007, the “alternative finance return” (the rent element of your HPP) is treated as if it were interest for income tax. HMRC’s SAIM2250 manual confirms this. So an individual landlord on a BTL HPP is restricted to basic-rate (20%) relief on that rent under Section 24, exactly like a conventional mortgage. A limited company is not subject to Section 24.
How much deposit do I need for a halal buy-to-let?
Typically 25–30% of the purchase price. Al Rayan’s BTL Home Finance generally caps the bank’s share (Finance-to-Value) around 70–75%, and Gatehouse’s BTL HPP range is broadly similar. A bigger deposit lowers the bank’s rent and makes the rental-cover stress test easier to pass. Confirm the current FTV cap with the provider, as ranges change.
What is the rental-cover stress test on a BTL HPP?
The bank checks that the property’s expected rent comfortably exceeds the rent you owe it — usually 125% to 145% cover — and it runs that check at a higher “stress” rental rate (often 1–2 points above the real rate). A deal that only just balances today will fail. Higher-rate taxpayers and limited companies usually face the higher cover requirement.
What is the gross vs net yield on a £180k halal BTL flat?
In our worked example, £875/month rent on a £180,000 flat is a 5.83% gross yield. After the bank’s HPP rent and running costs, net cash flow is roughly break-even to slightly positive — very sensitive to the Ijara rental rate. Net yield only turns clearly positive with a higher gross yield, a competitive bank rate, or a larger deposit. The acquisition portion of your payment is excluded from yield because it buys equity, not an expense.
Should I buy my halal BTL through a limited company (SPV)?
Possibly. Companies are not subject to Section 24, so an SPV can deduct HPP rent in full before Corporation Tax — valuable for higher-rate taxpayers building a portfolio. Both Al Rayan and Gatehouse can finance SPV applicants. Weigh the tax saving against extra accountancy and filing costs and often slightly higher company finance rates, and take advice from a qualified accountant and a scholar-supervised provider.
