Remortgaging a warehouse

A commercial remortgage is the process of replacing the existing loan on a commercial property with a new one, either with the same lender or a different one, to secure a better rate, release equity or change the terms. Remortgaging a warehouse means moving the commercial mortgage on that industrial asset onto fresh terms, usually because the current deal is coming to an end, the rate has become uncompetitive, or the building has risen in value and there is equity worth releasing. We arrange commercial remortgages as an introducer rather than a lender, reading the market and placing your case with the lender most likely to improve on what you have.

This guide explains what a commercial remortgage is, why owners remortgage a warehouse, how the process works, how long it takes and what a lender looks at. We have written it for owner-occupiers whose business trades from the building and for investors holding it for rental income. Throughout we are clear that a remortgage is worth doing only when the new deal genuinely beats the old one after costs, and we point out where a different route, such as a further advance or a short bridging facility, might suit a particular need better than a full refinance.

Can you remortgage a commercial property?

Yes, you can remortgage a commercial property, and it is a routine part of owning a warehouse or industrial unit for the long term. A commercial remortgage replaces your current commercial mortgage with a new facility secured on the same building, either to reduce the interest rate, to release equity that has built up as the property has risen in value, or to change the structure of the loan such as the term or the repayment basis. The new lender takes a charge over the warehouse, repays the existing lender, and you continue with the building under improved terms.

Owners remortgage for several reasons. The most common is that a fixed or introductory rate has expired and the loan has reverted to a higher variable rate, so a remortgage onto a fresh deal cuts the monthly cost. Another is to release equity: a warehouse bought years ago may now be worth considerably more, and a remortgage can free some of that increased value as cash to fund another purchase, works or business investment. A third is simply to restructure, shortening the term to clear the debt faster or switching between fixed and variable interest rates.

A commercial remortgage differs from a standard homebuyer remortgage in the same ways a commercial mortgage differs from a residential one. The lender assesses the property, the borrower and the ability to repay rather than running a simple affordability calculator, and for an investment warehouse it focuses on the rental income and the lease. That means the new rate, loan to value and term are the product of underwriting judgement, which is exactly why placing the case with the right lender, and presenting it well, has such a large effect on the outcome.

Why remortgage a warehouse, and what are the advantages?

The headline advantage of remortgaging a warehouse is cost. If your current commercial mortgage has reverted to a high standard variable rate, or you signed it when rates were higher, a remortgage onto a keener rate can reduce the monthly payment significantly over the life of the loan. Even a modest cut in the interest rate compounds into a meaningful saving across a long commercial mortgage term, which is why owners review their rate as deals expire rather than letting the loan drift onto whatever the lender charges by default.

Releasing equity is the second major reason. A warehouse that has appreciated since purchase holds equity that a remortgage can unlock, providing cash to fund a deposit on another property, capital works, or wider business investment, all secured at a commercial mortgage rate that is cheaper than most other borrowing. Because industrial values have been firm, with prime industrial yields holding broadly stable at around 5.00 to 5.25 percent according to Knight Frank in December 2025, many owners find their building is worth more than they realised and there is genuine equity to put to work.

Restructuring is the third advantage. A remortgage is the natural moment to reshape the loan: reducing the commercial mortgage term to own the warehouse outright sooner, switching from interest-only to repayment or the other way round, or moving between a fixed and a variable rate to match your view on where interest rates are heading. We model the new deal against the old one in full, including the arrangement fee, valuation, legal cost and any early repayment charge, because a remortgage only makes sense when it beats the existing loan after every cost is counted.

How does the commercial remortgage process work?

The process mirrors a purchase but without a seller. We start by understanding your current loan, the rate, the balance, the term remaining and any early repayment charge, and the building, its current value and, for an investment warehouse, its rental income and lease. With that picture we approach lenders for an indicative decision, so you can see whether a remortgage will genuinely improve on your existing deal before you commit any cost to the process.

Once you choose a lender, it instructs a formal valuation of the warehouse. A surveyor inspects the building and reports its market value and, for an investment case, its rental value, and the new loan is a percentage of that valuation. The valuation matters as much on a remortgage as on a purchase, because the equity you can release and the loan to value you achieve both depend on it. After a satisfactory valuation the lender issues a formal offer, solicitors handle the legal work to redeem the old charge and register the new one, and the funds move between lenders on completion.

Timing is the question owners ask most, and a commercial remortgage usually takes between six and twelve weeks from application to completion, broadly similar to a purchase because of the underwriting and valuation involved. It can be quicker where the case is clean and the lender already knows the asset, and slower where the lease or the title needs work. We recommend starting the process two to three months before your current rate expires, so the new deal is ready to take over the moment the old one ends rather than letting the loan revert to a higher rate in the gap.

How do commercial remortgage rates and repayment options work?

A commercial remortgage rate is set the same way as on a purchase, usually as a margin over a reference rate such as the Bank of England base rate or a swap rate, so the cost moves with the wider market. The exact rate you are offered on the new deal reflects the loan to value, the strength of the borrower, the quality of the warehouse and whether the loan is owner-occupied or investment. A lower loan to value, a strong trading business and a modern, easily lettable building all push the rate down, which is why a remortgage after the property has risen in value can secure a keener rate than the original loan.

A remortgage is also the moment to reconsider the repayment basis. You can move from interest-only to capital and interest repayment to start clearing the debt and owning the warehouse outright in time, or the other way round to lower the monthly payment and protect cash flow. You can shorten the term to pay the loan off faster, or lengthen it to ease the monthly cost. Because each of these changes the monthly payment and the total interest paid, we model the options on the actual figures rather than assuming the new deal should simply mirror the old one.

When comparing a remortgage rate against your current loan, the headline rate is only part of the picture. The new lender will charge an arrangement fee, often one to two percent, plus a valuation and legal costs, and your existing loan may carry an early repayment charge for leaving before its deal ends. We add all of these into the comparison, because a remortgage only makes sense when the saving on the rate, or the value of the equity released, genuinely outweighs the full cost of moving. Sometimes the answer is to wait until an early repayment charge falls away before refinancing.

How much equity can you release when remortgaging a warehouse?

How much equity you can release on a remortgage depends on the warehouse valuation and the loan to value the new lender will offer. If a building bought for four hundred thousand pounds is now valued at six hundred thousand, and the lender will advance seventy percent loan to value, the new loan could be up to four hundred and twenty thousand pounds. After repaying the existing balance, the difference is the equity released as cash, available for another purchase, capital works or wider business investment, all secured at a commercial mortgage rate.

The amount is constrained by the same income tests that govern any commercial loan. On an investment warehouse the lender checks that the rental income covers the larger loan with a margin, through a debt service cover calculation, so the rent effectively caps how much you can release regardless of the equity sitting in the building. On an owner-occupier loan the trading accounts must show the business can afford the bigger payment. So a property can hold equity that the income will not yet support releasing, and we test that before raising expectations.

Releasing equity through a remortgage is generally cheaper than most alternatives, because the loan is secured on a valuable, fundable asset at a commercial mortgage rate rather than an unsecured business rate. With industrial values having been firm, many owners find a remortgage frees more capital than they expected. We model the realistic figure, the valuation, the loan to value, the income test and the cost of the new loan together, so the equity you release is both genuinely available and comfortably supported by the income behind the warehouse.

How difficult is it to get a commercial remortgage approved?

A commercial remortgage is more involved than a residential one, but it is not difficult when the case is well prepared. The lender wants the same three things as on a purchase: a sound, fundable property, a credible borrower, and clear evidence of the ability to repay. For an owner-occupier that means two or three years of trading accounts showing the business can comfortably afford the payment, and for an investor it means rental income that covers the loan with a margin, tested through a debt service cover calculation.

The most common stumbling blocks are an over-optimistic view of the valuation, an early repayment charge on the existing loan that wipes out the saving, and applying to a lender whose criteria the warehouse does not fit. A short remaining lease on an investment property, or a building in a weak location, can also lower the loan to value a lender will offer or push up the rate. We check these points before the application, so we only approach lenders whose appetite matches the asset and the borrower, which is usually the difference between a smooth approval and a frustrating decline.

Because we are an introducer and not a lender, we widen the field of lenders you reach rather than sending you to a single bank that may say no. We know which lenders are remortgaging industrial property keenly, which are quick, and which will consider a less standard warehouse or a complex trading history. Placing the case once with the right lender, with the rate, the loan to value and the repayment basis matched to your circumstances, is what turns a commercial remortgage from a difficult exercise into a straightforward one.
