Are Islamic mortgages halal?
There is no single yes-or-no answer covering every product. Major standards bodies accept some Islamic home finance structures as permissible subject to specific conditions, and whether a particular product meets them depends on its contracts and how they are implemented. UK providers publish their own Sharia certification; this page records that evidence without adding a verdict.
Our position, stated once
We are researchers, not scholars. We report what standards bodies require, what certifiers have assessed and what remains unverified. We do not issue a religious ruling, and nothing here should be read as one.
There is no single halal mortgage contract to rule on
"Halal mortgage" and "Islamic mortgage" are consumer labels covering several different legal and contractual structures, and the scholarly assessment of each depends on what its contracts require. Diminishing musharaka is not ijara, and neither is a commodity murabaha, where the provider never owns your home at all. We set the structures out on the home purchase plan page.
The underlying concern is riba: the arrangements exist to finance a home without an interest-bearing loan. Whether one succeeds depends on who owns what, what the payment is for, who carries which costs, and what the parties have promised each other. So the answerable version of "are Islamic mortgages halal" is narrower: which structure, whose contract, assessed by whom, against what standard.
What the standards actually require
The International Islamic Fiqh Academy addressed diminishing musharaka directly in Resolution 136 (2/15), at its 15th session, Muscat, Sultanate of Oman, 14 to 19 Muharram 1425h, 6 to 11 March 2004. It did not say the structure is permissible. It said it is permissible subject to conditions, and the conditions are specific enough to fail.
The resolution has two layers. Paragraphs 1 to 4 set out what diminishing musharaka is and how it operates. Paragraph 5 then states that it is permissible subject to the general rules of partnership and to five further conditions. The table below summarises the requirements most relevant to home finance across both layers rather than reproducing the resolution's numbering, and marks which layer each one comes from.
| Requirement | In the resolution | What it requires |
|---|---|---|
| Loss shared by capital share | General feature | Each party bears his share of any loss incurred, commensurate with his share in the capital. |
| The buyout undertaking binds one party only | General feature | The binding undertaking to buy out the other party's share comes from one party, while the other retains the option to sell or not. Acquisition happens through sale contracts as shares are bought. |
| One partner may rent the other's share | General feature | One party may rent the other's share for a specified amount, with maintenance costs allocated according to capital share. |
| Shares sold at value on the day | Condition for permissibility | The purchase price of shares is determined at market value or a mutually agreed price on the day of sale. A pledge cannot guarantee purchase at par value. |
| Ownership costs charged to the partnership | Condition for permissibility | Insurance, maintenance and other costs are charged to the partnership account according to respective capital shares, rather than loaded onto one party. |
| Profit as a percentage, not a lump sum | Condition for permissibility | Profits are stipulated as percentage shares in the partnership. A lump sum, or a percentage of the subscribed principal, is not permitted. |
| Contracts kept independent | Condition for permissibility | The contracts and commitments relating to the musharaka transaction are kept independent from each other. |
| No guaranteed return of principal | Condition for permissibility | No stipulation may permit the return of the subscribed principal to a partner. |
International Islamic Fiqh Academy, Resolution 136 (2/15), read . Our summary, grouped by layer; the resolution text governs.
The lease side has its own resolution, and it is not a blanket approval
Ijara home finance belongs to the lease-to-own family, which the Academy treated separately in Resolution 110 (4/12) (12th session). It rules out arrangements where the same lease contract automatically becomes a sale contract, or where a sale takes effect only on completion of the rental payments. It permits forms where the lease and the sale are two separate and independent contracts concluded at different times, including a lease followed by a gift, by a purchase option at market price, or by a promise to sell at an agreed price.
The controls run the same way as the musharaka conditions: the leased property is guaranteed by the owner rather than the lessee, so damage not caused by the tenant falls on the lessor. Insurance should be cooperative and Sharia-compliant, and maintenance other than operational expenses is borne by the lessor.
International Islamic Fiqh Academy, Resolution 110 (4/12), read .
Whether contracts are genuinely independent of one another, whether the buyout undertaking binds one party or both, and who pays for the boiler are not presentational details. They are the conditions.
A permissible structure is not automatically a permissible product
A documented case shows this clearly. The AMJA Resident Fatwa Committee examined home finance companies in the United States. The committee ruled on eight named United States companies and did not reach the same answer about them. Some contracts were found compliant, some were permitted only in cases of need, and some were found impermissible because they functioned as interest-bearing loans. Two diminishing-partnership contracts did not get the same answer as each other.
It regarded Guidance Residential's diminishing-partnership contract as generally sound, and still identified violations on maintenance, taxes and insurance, because those expenses were not distributed according to percentage of ownership. It permitted dealing with the company in the face of need rather than issuing a clean ruling, and advised that the clauses be corrected.
Why that case matters here
Ownership costs allocated by share is one of the five conditions for permissibility in the Fiqh Academy resolution above. A real review of a real contract found a product carrying the right structure name and falling short on a named condition: the argument for reading the contracts rather than the label.
Scope note
This says nothing about the UK providers. It shows how substantive scholarly review proceeds, and is not a finding about Gatehouse Bank, Offa or StrideUp. We have not seen an equivalent published review of the UK products.
AMJA Resident Fatwa Committee resolution, read .
That distinction is a current one, and a UK certifier makes it. Amanah Advisors, which certifies Offa's plan today, draws it inside the certificate itself: "This certification pertains to the reviewed documentation and processes only. Correct implementation in accordance with the reviewed materials remains the sole responsibility of the relevant parties, including the end-user." A certificate is a finding about documents on a date, not a warranty about how they are operated afterwards.
Certification published by the three mainstream providers

The thing worth noticing
Offa and StrideUp are certified by the same organisation, Amanah Advisors. Across the three providers that is two distinct certifying organisations, not three.
Certificates are not votes. It does not follow that Offa and StrideUp received the same assessment: a shared certifier is not a shared contract, and we have not compared their documents.

Being FCA-regulated is not being Sharia-certified
The FCA has addressed this directly. Asked whether home purchase plans are limited to arrangements designed to comply with Islamic principles, its guidance says nothing in the definition suggests that, while noting it is primarily directed at arrangements of that kind.
The category is defined by who buys the property, who is obliged to acquire it and who occupies it. Nothing in that test refers to Sharia, so it tells you about your consumer protections rather than about permissibility.

What we could not verify
- Whether Gatehouse's certificate covers today's documents. It is dated 27 January 2022 and names the seven Home Purchase Plan documents its board reviewed then. We have not been able to check that every current version remains materially unchanged.
- StrideUp's certificate document. StrideUp states Amanah Advisors certifies its plan. We did not locate the certificate itself, so we cannot record its date or which contracts it covers.
- Whether the UK products satisfy each condition. That requires reading the executed contracts against the resolutions, which is scholarly work on documents we do not hold. No published review of the UK products at that level came to hand.
- The other 10 propositions in our register. Only the three mainstream providers have been checked to this standard, which is why the register carries no Sharia governance field yet.
What to do with all of this
If permissibility decides it for you, ask the provider specific questions. Who certified the product, and does the certificate cover the version you are offered? How are insurance, maintenance and taxes allocated? Does the purchase undertaking bind you, the provider, or both? Can you see the certificate and its date?
Then take the answers to someone qualified to weigh them. That is not us, and it is not a comparison site.

Common questions
- Are Islamic mortgages halal?
- There is no single Islamic mortgage contract to rule on. The International Islamic Fiqh Academy permits diminishing musharaka subject to five specific conditions, and separately addresses lease-to-own arrangements, where it distinguishes permissible forms from prohibited ones rather than accepting the category. So whether a particular product qualifies is a question about that product’s contracts. Each UK provider publishes its own certification, and we record that evidence rather than issuing a religious ruling.
- Does FCA regulation mean a product is Sharia-compliant?
- No, and the two are unrelated. The FCA has said there is nothing in the definition of a home purchase plan to suggest it is limited to arrangements designed to comply with Islamic principles. A home purchase plan is a regulatory category defined by ownership, obligation and occupation. Sharia compliance is assessed separately, by scholars.
- Who certifies the mainstream UK home purchase plans?
- Gatehouse Bank is certified by its own Shariah Supervisory Board, whose three named members signed its Home Purchase Plan certificate. Offa and StrideUp both state their products are certified by Amanah Advisors. That is two distinct certifying organisations across the three providers, not three.
- If a product is called diminishing musharaka, is that enough?
- The name is not the assessment. The Fiqh Academy resolution sets conditions including that contracts are kept independent of each other, that profit is a percentage rather than a lump sum, and that insurance and maintenance are charged to the partnership by share. Scholarly reviews of real contracts have found products carrying the right structure name while falling short on those conditions.
