Building and refurbishing UK property with Sharia-compliant funding

Why development needs special structures

A finished building can simply be bought and leased, but a development site produces no rent until completion. Islamic finance must therefore fund an asset that does not yet exist, without charging interest during construction. Scholars use manufacturing, forward-lease and partnership contracts to solve this.

Istisna’ and forward ijara explained

Under istisna’ the bank commissions the building and pays in stages as work progresses, while the developer builds it. A forward lease, ijara mawsufa fi al-dhimma, lets the bank agree rent on the future building, with advance rentals paid during construction and credited later.

• Istisna’: staged payments for an asset to be manufactured or built.
• Forward ijara: lease of a described future asset with advance rentals.
• Murabaha tranches: commodity trades drawn down to match each construction stage.
• Musharakah: equity-style partnership sharing profit and loss on the scheme.

Equity partnerships for larger schemes

In a musharakah, the bank and developer both contribute capital to a project company and share profit by agreed ratio, with losses in proportion to capital. This suits build-to-rent and student housing schemes, where the bank may stay invested after completion.

Tax points for developers

Developers usually trade through companies, and HMRC’s alternative finance rules treat the return under purchase and resale or profit share arrangements as a loan relationship for corporation tax. Land purchases pay Stamp Duty Land Tax at non-residential rates when the site is not residential.

Regulation and lender types

Development finance to companies is unregulated, but banks offering it are authorised by the PRA and FCA. Non-bank Islamic bridging lenders may hold FCA permissions for other activities, such as Offa, which is authorised under reference 1000573 and certified by Amanah Advisors.

Who funds Islamic development in 2026?

QIB (UK) offers Structured Real Estate finance to buy, refinance or develop residential and commercial assets, including student accommodation and logistics. BLME, owned by Boubyan Bank, provides UK companies with acquisition and development finance, with a strong Gulf client base.

For short-term needs, Offa offers Islamic bridge finance and bridge-to-let products, and Gatehouse Capital provides Sharia-compliant, non-regulated bridging from 0.69% a month with terms of three to twelve months. These suit auction purchases and light refurbishment rather than ground-up construction.

Realistic limits for small developers

Ground-up construction finance under £5 million is hard to find on a Sharia-compliant basis. Small developers often combine Islamic bridging for the site purchase with their own equity for the build, or partner with investors through a musharakah-style joint venture.

What lenders assess on a scheme

Lenders review planning consent, build costs, the contractor, the gross development value, pre-sales or pre-lets and the developer’s track record. Most fund a share of costs and expect the developer to put in meaningful equity, often in the land.

Financing a development step by step

1. Secure the site and obtain planning permission or a clear planning route.
2. Prepare a development appraisal with costs, timeline and gross development value.
3. Approach Islamic banks or bridging lenders with the appraisal and track record.
4. Agree the structure, whether istisna’, forward ijara, murabaha tranches or musharakah.
5. Commission a valuation and an independent monitoring surveyor.
6. Sign the facility, then draw funds in stages against certified construction progress.
7. Exit by sale of units or refinance into a long-term Islamic investment facility.

A clear exit strategy is essential. Banks want to know whether units will be sold, held for rent with an ijara investment facility, or refinanced, and the expected timing must fit within the term of the development facility.

Typical costs and documents

Mistakes that derail Islamic development deals

• Starting construction before the Sharia structure and facility are signed.
• Underestimating build costs, leaving no contingency for overruns.
• Planning a use the bank cannot finance, such as a bar or betting shop unit.
• Relying on bridging for a long build without a refinance route.
• Weak contractor or no track record on schemes of similar size.

Can bridging be used for refurbishment?

Yes. Islamic bridging is often used to buy and refurbish homes or HMOs, then refinance into a buy-to-let purchase plan. Gatehouse Capital considers HMOs and multi-unit blocks, and Offa offers bridge-to-let finance designed for this route.

How is profit fixed on a staged build?

Under istisna’ the price is agreed at the start, while under forward ijara the rent is agreed for future periods, often linked to a benchmark. Murabaha tranches lock in profit as each trade is executed, so the developer knows the cost of every drawdown.

What happens if the project overruns?

The developer usually bears cost overruns and must fund them with equity. In a musharakah, losses are shared by capital ratio, but banks protect themselves through guarantees and performance undertakings, which must still respect Sharia limits on guaranteeing profit.

Is planning gain or CIL financed too?

Section 106 contributions and the Community Infrastructure Levy are part of development costs and can be included in the appraisal. Whether they are funded by the bank or by developer equity depends on the facility terms, so they should be raised at the indicative terms stage.

Do these lenders accept overseas developers?

Yes in many cases. QIB (UK) and BLME serve clients from the Middle East, using UK or offshore companies. Overseas sponsors should expect detailed know-your-customer checks and may need a UK-based development manager and local professional team.
