Industrial Property Development Finance in 2026

Constrained supply is the quiet engine under the whole industrial story. It is the reason the sector’s rents keep moving, with constant demand from retailers, manufacturers, third-party logistics operators, trades and growing SMEs pressing against a limited stock of good units. And it is the reason a ground-up shed scheme is financeable at all, because a lender backing a new industrial building is really backing the gap between what it costs to build and what the finished space is worth to occupiers who cannot find it anywhere else.

That gap is what industrial property development finance is built to fund. This piece follows a scheme through in the order a lender thinks about it: what the money pays for, the terms and leverage on offer in 2026, how the facility is drawn and how interest rolls up, the appraisal a lender wants to see, how refurbishment underwriting differs from ground-up, and finally the exit that repays the whole thing. It is written from the desk we run at Industrial Property Finance, arranging this lending UK-wide.

What industrial development finance funds

Development finance covers the build, not just the land. At the ground-up end it funds new industrial units and distribution warehouses, from a single detached shed to a multi-unit trade park delivered in phases. In the middle sit heavy refurbishments and extensions: taking a tired unit back to shell, re-cladding, raising the eaves, adding capacity or reconfiguring a site so it lets to a modern occupier. What these share is that the asset is not yet in its finished, income-producing state, so a standard commercial mortgage does not fit and a facility that releases money against build progress does.

The distinction matters because it drives everything downstream. A term lender underwrites an asset that already exists and already earns. A development lender underwrites a plan: a set of costs, a programme, and a value that only appears once the work is done. The development finance explained guide on the parent site sets out that framing in more depth, and it is the mindset to bring to every figure below.

Terms and leverage in 2026

The two numbers that cap an industrial development facility are a percentage of cost and a percentage of gross development value, and the lender lends to the lower of the two. In 2026 we typically see up to 65 to 75 percent of total scheme cost and up to 60 to 65 percent of GDV, with pricing from around 8 percent per annum, usually rolled up rather than paid monthly. Arrangement fees are typically 1 to 2 percent.

Where a developer wants to put in less cash, mezzanine can sit behind the senior facility as a second charge and top the funding up to around 85 to 90 percent of cost, in exchange for a higher preferred return, often 8 to 15 percent. That reduces day-one equity but raises the blended cost of capital, so it is a deliberate trade. The base rate backdrop is supportive: the Bank of England has held at 3.75 percent since its December 2025 cut, and with UK industrial and logistics investment reaching £10.5 billion in 2025 there is genuine appetite for well-structured schemes. The cleanest way to see how the cost and GDV caps interact on your own numbers is the development finance calculator.

How drawdowns and interest roll-up work

A development facility does not land in your account on day one. It is drawn in stages against build progress, typically with a monitoring surveyor signing off each stage before the next tranche is released. That protects the lender, because money only follows work that has actually been done, and it protects the developer’s costs, because you are not paying interest on funds you have not yet used.

Interest is normally rolled up rather than serviced monthly. Instead of paying interest out of pocket during the build, when the scheme is producing no income, the interest is added to the loan and settled at the end out of the exit. That is why the facility is quoted against total cost including a finance line: the rolled-up interest is part of the cost the lender is funding. It keeps a scheme’s cash flow clean through construction, but it also means the debt grows over the term, which is one more reason the exit has to be credible from the outset.

The appraisal a lender wants to see

Development lending is granted on a plan, so the plan has to stand up. The appraisal a lender wants is the document that ties the whole scheme together: land cost, a full and realistic build-cost budget with contingency, professional fees, finance costs, the programme, and a GDV supported by evidence rather than optimism. On the value side that means comparable rents and yields for finished industrial space in the location, because GDV on a let scheme is a function of the rent it will command and the yield an investor will pay.

The stronger the evidence, the further the terms move in your favour. A fixed-price build contract, a capable contractor, a contingency that reflects the real risk in the programme, and demonstrable occupier demand all pull the lender’s confidence up and its pricing down. Thin or aggressive numbers do the opposite. Getting the appraisal right before it goes to a lender is most of the work, and it is where our experience as a specialist industrial finance arranger earns its keep. Realistic build costs, an honest contingency and evidenced GDV are the three lines a monitoring surveyor will test first.

Refurbishment against ground-up

Not every industrial scheme is a new build, and the underwriting shifts with the work. A light-to-heavy refurbishment of an existing unit is underwritten differently from a ground-up scheme because the starting point is different: there is already a building and often a value in the ground, the works are shorter, and the risk sits more in the scope and less in the whole planning-and-construction arc. That usually means a lender is comfortable at the firmer end of the leverage range and a shorter facility.

Ground-up is the fuller risk. There is planning to satisfy, a longer programme, and a value that only exists on paper until the building is up and let. Lenders price and gear accordingly, and they lean harder on the contractor, the contract and the contingency. Between the two sits a spectrum, and where a specific scheme lands on it is what sets the terms. It is worth being clear which one you are financing, because a refurbishment dressed up as a development, or the reverse, gets repriced quickly once a surveyor looks at it.

The exit that repays the loan

A development facility is short-term money, and it is only as good as its exit. There are three routes, and a lender wants to see which one you are aiming at before it lends. The first is a sale: you build, you sell the finished units, and the sale proceeds clear the debt and the rolled-up interest. The second is a refinance onto term debt: you let the scheme, then move it onto a refinance or term loan from around 6 percent over 5 to 25 years, so the development facility is repaid and the completed, income-producing asset carries long-term debt against its rent.

The third route matters when the build finishes before the sale or the term refinance is ready. Development exit bridging repays the development lender on completion and buys time to sell the units or arrange the term facility without pressure, and it is often cheaper than letting the development rate run on past practical completion. Choosing between a term refinance and a development exit bridge is a real decision with a cost attached each way, and the guide on bridging against development finance sets out when each fits. Whichever exit you plan for, the discipline is the same: the exit is not the last thing you think about, it is the first.

Common questions on industrial development finance

How much can you borrow for an industrial development? Up to around 65 to 75 percent of total scheme cost and up to 60 to 65 percent of GDV, with the lender advancing to the lower of the two. Mezzanine behind the senior facility can lift the funding to around 85 to 90 percent of cost where the scheme and the developer support it, at a higher cost of capital.

Do you pay the interest monthly during the build? Usually not. Interest is typically rolled up and settled at the end from the exit, which keeps cash flow clean while the scheme is producing no income. The trade-off is that the debt grows over the term, so the exit, whether a sale or a term refinance, has to be sized to repay the loan plus the rolled-up interest with room to spare.

We arrange industrial property development finance as a finance arranger and introducer, not a lender, and we do not provide financial, legal or tax advice. Industrial development finance for limited companies, investors and business borrowers is unregulated commercial lending that sits outside the Financial Conduct Authority’s regulated mortgage perimeter. Some lending, for example to an individual secured on a property linked to their home, can be a regulated mortgage contract, and we refer those cases to an appropriately authorised firm. All rates, leverage and figures here are indicative and depend on the scheme.
