Halal Buy-to-Let in the UK: A £200k Rental Property Worked Example at 5.88%
A halal buy-to-let mortgage replaces interest with a Shariah Buy-to-Let Purchase Plan (BTL HPP): the bank co-owns the property and you pay it rent on its share, while your tenant pays you rent on the whole thing. On a £200,000 property with a 25% deposit and Gatehouse Bank's BTL rental rate from 5.88%, the bank's monthly rent is about £735 against £1,200 of tenant rent — a gross-of-tax surplus of roughly £465/month before costs. The catch most articles miss: HMRC treats those Purchase Plan payments exactly like mortgage interest, so the Section 24 restriction hits you the same way.
How a Shariah BTL Purchase Plan differs from a residential HPP
If you've read about residential Islamic home finance, you already know the Home Purchase Plan (HPP): a co-ownership (diminishing Musharaka) arrangement where the bank and you jointly own the property, and you pay the bank rent on the share you don't yet own while gradually buying it out.
A Buy-to-Let HPP uses the same legal skeleton — co-ownership plus a lease — but the cash flows have two rent streams instead of one:
- Residential HPP: the bank rents its share of the home to you, and you live in it. One rent payment (you → bank).
- Buy-to-Let HPP: the bank still rents its share to you, but you don't live there — you sub-let the property to a tenant, who pays rent to you. Two rent flows: tenant → you, and you → bank.
So you sit in the middle. Your job as the investor is to make sure the rent coming in from the tenant comfortably exceeds the rent going out to the bank, after costs. Economically it behaves like a conventional buy-to-let mortgage, but the contract is a co-ownership lease rather than a loan, which is what makes it acceptable under Shariah. Most UK providers (Gatehouse Bank, Al Rayan Bank) offer this on an interest-only-equivalent basis — your monthly payment is pure rent to the bank, and you only buy out the bank's share when you sell or refinance, mirroring how conventional BTL landlords use interest-only mortgages.
Worked example: £200,000 property, 25% deposit, 5.88% rental rate
Worked example — "Fatima's first rental flat"
Fatima is a higher-rate taxpayer (she earns £60,000 from her day job). She buys a £200,000 two-bed flat in Birmingham to let out. She takes a Gatehouse Bank Buy-to-Let Purchase Plan with a 25% deposit and a fixed rental rate of 5.88%. A local letting agent confirms market rent of £1,200/month.
Step 1 — The split.
- Deposit (Fatima's initial share): 25% × £200,000 = £50,000
- Bank's share (finance amount): 75% × £200,000 = £150,000
Step 2 — Rent Fatima pays the bank. The 5.88% rental rate applies to the bank's £150,000 share:
- £150,000 × 5.88% = £8,820 per year
- ÷ 12 = £735/month to the bank
Step 3 — Rent the tenant pays Fatima. £1,200/month.
Step 4 — Gross monthly position (before other costs and tax):
- £1,200 (tenant in) − £735 (bank out) = +£465/month
Step 5 — Real-world costs. Strip out the things that actually eat the surplus: letting-agent fee (~10% = £120/mo), insurance + maintenance allowance (~£100/mo), and void/voids reserve. Net operating surplus before tax lands nearer £245/month (≈ £2,940/year) — and Fatima still owes tax on the rent, with only a restricted credit for that £735 (see below).
| Line item | Monthly | Annual |
|---|---|---|
| Tenant rent received | £1,200 | £14,400 |
| Rent paid to bank (5.88% on £150k) | −£735 | −£8,820 |
| Letting agent (~10%) | −£120 | −£1,440 |
| Insurance + maintenance reserve | −£100 | −£1,200 |
| Net surplus before tax | ≈ £245 | ≈ £2,940 |

Rental cover: the Islamic bank's stress test vs a conventional BTL ICR
Conventional buy-to-let lenders won't lend just because the rent is bigger than the mortgage payment. They apply an Interest Cover Ratio (ICR): rent must exceed the monthly payment by a margin (commonly 125% for basic-rate landlords, 145% for higher-rate landlords like Fatima), and the calculation is run at a stressed rate (often ~5.5%+), not your actual pay rate.
Islamic BTL providers do the same thing — they just call it a rental cover or affordability test instead of an "interest" cover ratio, because there's no interest in the contract. The maths is identical: expected tenant rent ÷ stressed rent-to-bank ≥ the required cover percentage.
Worked example — does Fatima pass?
Say Gatehouse stress-tests at a notional 145% cover at a 6.5% assessment rate (illustrative — each lender sets its own).
- Stressed rent to bank: £150,000 × 6.5% ÷ 12 = £812.50/mo
- Required tenant rent: £812.50 × 145% = £1,178/mo
- Fatima's actual rent: £1,200/mo → passes, but only just.
If her flat only let for £1,150, she'd fail the cover test even though £1,150 still clears the real £735 payment with room to spare. The stress rate and cover margin — not your day-one cash flow — decide how much the bank will finance.
UK tax: Section 24 and whether HPP rent gets the same treatment
This is where halal investors most often get tripped up — and where the news is, frankly, neutral: a halal BTL is taxed almost identically to a conventional one.
Since the 2020-21 tax year, individual landlords can no longer deduct finance costs (mortgage interest) from rental income. Instead, you declare the full rent as taxable, then receive a basic-rate (20%) tax-reduction credit on your finance costs. HMRC's own guidance states the relief "is being restricted to the basic rate of Income Tax" and the reduction is "the basic rate value (currently 20%)" of the lower of your finance costs, property profits, or adjusted income above the personal allowance (GOV.UK — tax relief for residential landlords).
Do Purchase Plan rent payments count as a "finance cost"? Yes. HMRC's helpsheet HS340 is explicit: you can claim relief for "alternative finance payments paid on a qualifying alternative finance arrangement on the same basis as someone claiming relief for interest paid on a loan" (GOV.UK HS340). So your £735/month rent to the bank is the equivalent of "mortgage interest" for tax — it gets the same restricted 20% credit, not a full deduction.
Worked example — Fatima's tax bill on the rent
Using 2026-27 thresholds: personal allowance £12,570, basic rate to £50,270, higher rate (40%) above £50,271 (GOV.UK Income Tax rates). Fatima already earns £60,000, so all rental profit is taxed at 40%.
Take a simplified year — £14,400 rent in, £8,820 paid to the bank, £2,640 other allowable costs (agent, insurance, maintenance):
- Taxable rental profit (the bank rent is not deducted): £14,400 − £2,640 = £11,760
- Tax at 40%: £11,760 × 40% = £4,704
- Finance-cost credit: 20% × £8,820 = −£1,764
- Net tax due on the rental: £2,940
Had the old rules survived, she'd have deducted the £8,820 first and paid 40% on just £2,940 = £1,176. Section 24 costs her ~£1,764 extra — the same penalty a conventional higher-rate landlord pays. There is no halal tax advantage and no halal tax penalty here.
Limited company SPV vs personal ownership — and who lends to a Ltd
Because Section 24 hits individuals only, many higher-rate landlords hold rentals through a limited company SPV (Special Purpose Vehicle — a company that does nothing but hold property, usually SIC code 68209). GOV.UK's Section 24 guidance is explicitly written for "individual landlords"; companies aren't subject to that finance-cost restriction.
| Personal ownership | Ltd company SPV | |
|---|---|---|
| Tax on rental profit | Income Tax (20%/40%/45%) | Corporation Tax (lower for many) |
| Bank rent deductible? | No — only a 20% credit (Section 24) | Yes — fully deductible expense |
| Profit extraction | It's already yours | Dividends/salary — taxed again on the way out |
| SDLT surcharge on purchase | +5% on additional property | +5% (companies pay it from the first property) |
| Admin | Self Assessment | Annual accounts + Corp Tax return |
The 5% Stamp Duty surcharge on additional residential property applies either way (GOV.UK SDLT residential rates) — and on a Shariah HPP, SDLT is charged once on the purchase, not again when you buy out the bank's share, because of specific alternative-finance relief in the tax legislation.
Which Islamic providers lend to a Ltd? Both major UK Shariah banks underwrite SPV limited-company applications for Buy-to-Let Purchase Plans:
- Gatehouse Bank — offers BTL Purchase Plans to UK-resident individuals and SPV limited companies (and to UK expats and international landlords).
- Al Rayan Bank — offers Buy-to-Let Purchase Plans to individuals and SPV limited companies.
A typical condition is that the company must be a "clean" SPV (property-holding only, recent SIC code), and directors usually give personal guarantees. The decision between personal and SPV ownership is genuinely fact-specific — it turns on your tax band, how many properties you plan to hold, and whether you'll draw the profit out or roll it up. Run the numbers with a property-tax accountant before you incorporate.

Frequently asked questions
Is a halal buy-to-let mortgage more expensive than a conventional one?
Rental rates on Shariah BTL Purchase Plans (e.g. Gatehouse Bank from 5.88% in early 2026) are broadly in the same range as conventional BTL mortgage rates, though they can run a little higher because the Islamic-finance market is smaller. The bigger cost difference comes from product fees and the limited number of lenders, not the headline rate itself.
Do I pay tax on the rent I pay to the Islamic bank?
You don't pay tax on it, but you can't deduct it from your rental profit either. HMRC treats alternative-finance (Purchase Plan) payments the same as mortgage interest, so under Section 24 individual landlords get only a 20% basic-rate tax-reduction credit on it — not a full deduction. See GOV.UK helpsheet HS340.
What deposit do I need for a halal buy-to-let?
Typically 25% or more of the property value. In the worked example above, a £200,000 flat needs a £50,000 (25%) deposit, leaving the bank to finance £150,000. Some products require larger deposits for expat or international landlords or for HMO/multi-unit properties.
How does the bank decide how much it will finance?
It runs a rental-cover (affordability) test: your expected tenant rent must exceed the rent you'd owe the bank at a stressed assessment rate, by a required margin — commonly around 125% for basic-rate and 145% for higher-rate landlords. This is the Shariah equivalent of a conventional lender's Interest Cover Ratio (ICR).
Can I hold a halal buy-to-let through a limited company?
Yes. Both Gatehouse Bank and Al Rayan Bank offer Buy-to-Let Purchase Plans to SPV limited companies as well as to individuals. Because the Section 24 finance-cost restriction applies to individuals and not companies, higher-rate landlords often use an SPV — but profit extraction and extra admin can offset the saving, so take tax advice first.
Do I pay Stamp Duty twice on a Shariah HPP because the bank co-owns it?
No. Specific alternative-finance relief in UK tax law means SDLT is charged once on the original purchase, not again when you gradually buy out the bank's share. The 5% additional-property surcharge still applies to the purchase if it's not your only home.
