Commercial Mortgage Deposits, LTV and Criteria in 2026: What Lenders Actually Ask For

The first question almost every business owner asks us is how big a commercial mortgage deposit they need, and the honest 2026 answer is that the deposit is where the conversation starts, not where it ends. On a standard commercial case this year, expect to put in 25 percent or more, because most lenders cap the loan at 75 percent of value or purchase price. That number is the headline, but it is only one of four or five things an underwriter weighs before a case becomes an offer. As a broker desk placing these loans every week, we spend as much time on the serviceability and the accounts as we do on the deposit, because a strong deposit on a case that does not service is still a decline, and a modest deposit on a business that clearly covers the payments will often go through. This article sets out what lenders actually ask for in 2026, and where the room to move really sits.

Why the deposit sits where it does in 2026

The reason a commercial deposit is larger than the one a homeowner puts down comes back to how lenders see the risk. A residential mortgage is secured against a home the borrower has a strong personal reason to keep paying for, in a market with millions of comparable sales to value against. A commercial property is an income asset or a trading premises, valued on yield and covenant rather than on rows of near-identical houses, and it is harder to sell quickly if the loan goes wrong. Lenders price that difference into the loan to value they will offer, and in 2026 that leaves the standard ceiling at 75 percent, with a deposit of 25 percent or more to match.

The wider rate picture reinforces it rather than loosening it. The Bank of England base rate has stood at 3.75 percent since the cut in December 2025, held again at the June decision, and a steady rate has kept lender appetite reasonably open through the first half of the year. But a held base rate does not push maximum LTVs higher; it simply makes the loan a business can carry easier to size, because the cost of money underneath the whole market is not lurching around. The deposit requirement is a function of the asset and the downside, and those have not changed just because the rate has settled.

Where the LTV can stretch, it tends to be on the strongest owner-occupier cases, where the business trading from the building gives the lender a second layer of comfort beyond the bricks. Where it tightens, it is on specialist property, weaker covenants or a trading history that does not yet stand up. The 75 percent figure is the anchor, and the deposit conversation is really a conversation about which side of it a particular case sits.

What actually counts as your deposit

One of the most useful things we do early in an enquiry is widen what a borrower thinks of as their deposit, because it is rarely just cash in a business account. Three forms come up again and again in 2026.

Cash is the simplest. Money held by the business or the individuals behind it, evidenced and clean, is the deposit most underwriters are happiest with, because its source is easy to check and it is unambiguously the borrower’s own stake.

Equity in another property is the one most owners underuse. A borrower who already owns commercial or residential property with headroom in it can often raise the deposit against that asset rather than finding fresh cash, whether by a second charge or by refinancing the existing property to release funds. It turns dormant equity into the stake for the next purchase, and for a business that is asset-rich but cash-conscious it is frequently the difference between a deal happening this quarter or next year.

Director loans are the third, and they need care. Money a director lends into their own company can form part of the deposit, but the lender will want to see where it came from and how it sits on the balance sheet, and a genuine outside investment is treated differently from money simply routed through the business. A vendor leaving equity in a deal, or a gifted contribution, can also feature, but each of those changes how an underwriter views the borrower’s real skin in the game, which is the thing the deposit is meant to prove.

The deposit gets a case to the table. Serviceability, the accounts and a clean exit are what get it a term sheet.

Serviceability is the test the deposit cannot buy you out of

Assume the deposit is there. The next question, and usually the harder one, is whether the property or the business can carry the payments with room to spare. Lenders measure this with cover ratios, and they stress-test them, meaning they do not check that the numbers work at today’s pay rate but at a higher assumed rate, so the loan still stands up if borrowing costs rise.

On an investment case, where the loan is repaid from rent, the measure is interest cover, and in 2026 lenders want to see roughly 1.25 times to 2.00 times the interest covered by rent at the stressed rate, with the multiple rising for weaker tenants, shorter leases or more specialist buildings. On an owner-occupied or trading case, where the business itself services the loan, the measure is debt service cover, and the working band this year runs from about 1.25 times to 1.65 times, tested against the business’s profits rather than an external rent.

This is why a large deposit does not rescue a case that does not service. If the rent or the trading profit only just covers the payment at the stressed rate, no amount of extra deposit changes the underwriter’s core worry, which is whether the loan gets repaid month to month. It is also why the two levers work together: a bigger deposit means a smaller loan, a smaller loan means a lower payment, and a lower payment is easier to cover. When a case is tight on serviceability, adding deposit is often the cleanest way to bring it back inside the ratios, which is a very different thing from the deposit standing in for serviceability.

The criteria that sit alongside the numbers

Deposit and serviceability are the spine of a case, but a lender is underwriting several other things at the same time, and any one of them can move the rate or the answer.

Trading history and accounts come first. Most commercial lenders want two to three years of filed accounts or a clear set of management figures, and they read them for consistency and direction of travel as much as for the headline profit. A young business, or one with a dip in a recent year, is not shut out, but it narrows the field of lenders and usually costs something on rate, which is exactly where a broker earns the fee by knowing who looks past a single soft year.

Property type appetite is the next. Lenders sit in different places on what they will lend against. Standard offices, retail units, industrial and warehouse space and straightforward mixed-use tend to attract the widest choice and the keenest pricing. More specialist assets, from care and leisure to particular trading premises, have a shorter list of lenders and a higher rate to reflect the thinner resale market. Matching the property to a lender that genuinely wants it is half of getting a good outcome.

The borrower’s own profile matters too. Credit history, existing borrowing, the experience behind the business and the strength of the exit at the end of the term all feed the decision. On a trading business case, the rate band this year runs from about 7.0 percent to 9.0 percent a year, wider than the owner-occupier band of roughly 6.0 percent to 7.5 percent precisely because there are more of these variables in play. None of these is a simple pass or fail; they combine into a picture, and the picture is what the underwriter prices.

How the borrower is structured, and why it changes the case

Who is actually borrowing shapes the criteria as much as the property does. In 2026 we place commercial mortgages for individuals, trading limited companies, special purpose vehicles, partnerships and pension arrangements such as a SSAS, and each structure reads differently to an underwriter.

A trading limited company borrowing to buy the premises it operates from is a common and well-understood shape, and many owners now hold investment property through a special purpose vehicle set up for the purpose, which keeps the property ring-fenced and can be cleaner for lenders to assess. Partnerships, individuals buying in their own name and pension-held purchases each carry their own documentation and their own lender preferences. If a limited company sits at the centre of your plan, it is worth understanding how lenders view borrowing through a limited company before you fix the structure, because the wrapper you choose changes both the list of willing lenders and the guarantees they will ask for.

That last point is the one owners most often miss. Where a company or an SPV is the borrower, lenders almost always want personal guarantees from the directors or principals, so the individuals stand behind the corporate borrower. A guarantee is not a formality; it is the lender reaching past the company to the people, and it deserves proper advice before it is signed. It does not change the deposit, but it changes what is at stake, and any borrower should understand the guarantee they are giving as clearly as they understand the rate.

How the deposit affects the rate

The size of the deposit is one of the factors that affect the interest rates a lender will offer. A larger deposit lowers the loan to value, and a lower loan to value earns better commercial mortgage rates, because the lender is taking less risk on the money it advances. The wider mortgage rates on offer that month set the starting point, but the deposit is the lever the borrower controls, and putting in more is often the simplest way to reach a better rate. The deposit you take to the table is also the clearest signal of commitment a borrower can give, and lenders read it that way when they set their rates. It is worth understanding that the same case can price differently across lenders even at the same deposit, so knowing which lender rewards a stronger stake is part of the value a broker adds.

Putting a modest deposit in the best light

Not every business comes to us with a full 25 percent sitting in cash, and part of the job is presenting a case so that the deposit that is available does the most work. That can mean raising part of the stake from equity in another asset, timing the purchase around a trading year that shows the business at its strongest, or choosing the borrower structure that opens the widest field of lenders for that particular property.

It also means being honest about when a case needs more deposit rather than a cleverer presentation. A property in a thin resale market, a business with a short history or a tight serviceability position will genuinely borrow less, and the fastest route to an offer is sometimes to accept a lower LTV rather than to keep hunting for a lender who will stretch. Working with an independent commercial mortgage broker means those trade-offs are put in front of you early, with the panel of over one hundred lenders behind them, rather than discovered one decline at a time.

The twelve-month view on deposits and criteria

For the rest of 2026, the backdrop points to stability rather than change. A base rate held at 3.75 percent, lender appetite that has stayed reasonably open, and a 75 percent LTV ceiling that has not moved all suggest the deposit and criteria picture at the year end will look much like it does now. The businesses that place the cleanest cases will be the ones that treated the deposit as the opening move, got their accounts and serviceability in order, and chose a borrower structure that suited the deal rather than fighting it.

The message we give owners is consistent. Have the deposit clear and evidenced, know which parts of it are cash and which are equity or director funds, be ready to show that the property or the business covers the payments at a stressed rate, and think about the borrowing structure before the offer stage rather than after it. Those are the things that turn a 25 percent deposit into a completed commercial mortgage, and they are all in the borrower’s hands well before a lender is ever approached.

FAQs

How much deposit do I need for a commercial mortgage in 2026? Typically 25 percent or more of the value or purchase price, because most standard commercial mortgages are capped at 75 percent loan to value. The strongest owner-occupier cases can sometimes stretch a little further, while specialist property or weaker covenants may need more. Every figure here is an indicative 2026 band, not an offer.

Can I use equity in another property as my deposit? Often yes. Equity in commercial or residential property you already own can be raised by a second charge or by refinancing that property, and used as part or all of the deposit. It is one of the most underused routes for a business that owns assets but wants to keep its cash working elsewhere.

Does a bigger deposit fix a weak serviceability case? Not directly, but it helps, because a larger deposit means a smaller loan and a lower payment, which is easier for the rent or trading profit to cover at the stressed rate. What a deposit cannot do is stand in for cover altogether: if the case does not service at all, more deposit will not change the underwriter’s core concern.

Will I have to give a personal guarantee? Where a limited company or an SPV is the borrower, lenders almost always ask the directors or principals for personal guarantees, so the individuals stand behind the company. It does not change the deposit, but it does change what is at stake, and it should be understood and advised on before it is signed.
