Buying the premises your business trades from? You are starting from the cheapest position in the market. Start with Commercial Mortgages Broker and we will read the covenant before a single lender does.
If you assumed the best commercial mortgage rate goes to the borrower with the best building, the pricing says otherwise. In 2026 the cheapest money in the commercial market goes, as a pattern, to the owner-occupier: the business buying the premises it trades from. Not the professional landlord with a portfolio, not the investor with a long lease and a strong tenant, but the ordinary trading company buying its own shop, unit or office. It is a counterintuitive result, because the owner-occupier is often the least sophisticated borrower in the room, and it holds because commercial lenders price the covenant, meaning who is on the hook, more heavily than almost anything else. This piece unpacks why, what the spread actually looks like, and one market signal worth watching.
A disclosure before the argument, because it matters. Commercial Mortgages Broker is a trading style of Lenzie Consulting Ltd. We are a broker, not a lender, placing cases across a 100+ lender panel rather than funding them. Commercial mortgages for business purposes are generally not regulated by the Financial Conduct Authority (FCA); where a case is regulated it is referred to an appropriately authorised firm. Every figure here is an indicative market band for 2026, not an offer or a quote.

The covenant is the borrower, and the borrower is the price
A lender's first question on any commercial case is not really about the building. It is about who repays the loan and how reliably. That is the covenant, and the owner-occupier answers it in the strongest possible way: the business that repays the mortgage is the same business that runs inside the walls. The building is not an asset held at arm's length hoping for a return. It is the roof over the thing that generates the money, and a business will fight much harder to keep the premises it trades from than an investor will fight to keep one line in a spreadsheet.
Lenders know this, and they price it. When the borrower's own survival is tied to the building, the loan is repaid out of a motivation no tenant covenant can match. That is why, on the 2026 bands, an owner-occupier commercial mortgage runs at roughly 6.0 to 7.5 percent a year, the lowest of the standard product bands, priced against a debt service cover ratio of about 1.25 to 1.65 times on the trading profit. The building barely enters the calculation. The identity of the borrower does most of the work.
The spread, tier by borrower
Line the borrower types up and the covenant pattern becomes a visible ladder. On the indicative 2026 bands:
- Owner-occupier, buying its own trading premises: about 6.0 to 7.5 percent a year. Cheapest, because the borrower and the building are the same story.
- Commercial investment, a landlord letting to a tenant: about 6.5 to 8.5 percent, sized on rent against an interest cover ratio of roughly 1.25 to 2.00 times at the stressed rate. Dearer, because repayment depends on a tenant the lender did not choose.
- Trading business borrowing against wider activity rather than a single occupied premises: about 7.0 to 9.0 percent, the top of the standard range, because the income is the most variable of the three.
The ladder is not about the quality of the buildings, which may be identical. It is about how directly the borrower's own fortunes are tied to repaying the loan. The more the repayment depends on someone other than the borrower, a tenant, a market, a resale, the more the lender charges for the distance. Owner-occupiers pay least because there is no distance at all.
Why the cheap money is not automatic
None of this means an owner-occupier is handed the bottom of the band. The pattern sets the potential; the presentation realises it. A lender still reads the trading accounts, still stress tests the profit, and still wants a deposit of 25 percent or more against a loan of up to 75 percent of value. What the covenant advantage does is give the case a strong starting position, and the borrowers who capture it are the ones who show the business clearly: steady accounts, a serviceability position that clears the cover test with room, and a straight account of any bad year.
The owner-occupiers who miss the cheap money are usually the ones who present the case as if the building were the point. It is not. The building is the security. The business is the covenant, and the covenant is what the price is built on, so a case that puts the trading story front and centre is a case that gets read at the bottom of the band rather than the middle. The distinction between borrower types, and what each needs to show, sits in the money site's guide to who commercial lenders help.
The signal worth watching: the 48-hour DIP
There is a market signal in all this that is easy to miss. On a clean owner-occupier case, a Decision in Principle often comes back inside about 48 hours. That speed is not a service promise. It is information. When a lender can say yes in principle that fast, it is telling you the covenant is legible and the case sits squarely in appetite, which is exactly the position that earns the bottom of the band. A case that takes a lender weeks to form a view on is usually a case the lender is unsure about, and uncertainty shows up in the price.
So the DIP turnaround is worth watching as a proxy for how a lender sees the deal. A fast yes is a signal you are in the cheap lane and should hold out for a keen number. A slow, hedged response is a signal the case needs either better presentation or a different lender, and paying the first quote in that situation is how a borrower who could have been at 6.0 ends up nearer 7.5. Against a Bank of England base rate held at 3.75 percent since December 2025, with the next decision on 30 July, the floor under all of this has been stable enough that the differences between borrowers, rather than moves in the underlying rate, are what decide the number this year.
The lesson is short. Commercial money is priced on who borrows it, not just on what secures it, and the borrower closest to the building pays least. If you occupy the premises you are buying, you are starting from the cheapest position in the market, and the job is to present the case so a lender can see it.
