If you have ever been declined for business finance without a clear reason, the answer often sits in a single number you may never have seen. This is the Delphi score explained in plain terms: a commercial credit score produced by Experian that predicts how likely your business is to fail or fall seriously behind on payments over the next twelve months. Most UK lenders look at it before they look at anything else.
It is not the only thing that decides an application, but it shapes the starting point. A strong score opens the door to better rates, higher limits, and faster decisions. A weak one narrows your options and raises the cost of borrowing, sometimes for years. Understanding how the score works puts you in a far stronger position before you ever approach a lender.
This article walks through what the score measures, what counts as good, how lenders use it, and the practical steps that move it in the right direction.
What the Delphi Score Is, in Plain English
The Delphi score runs from 0 to 100. The higher the number, the lower the perceived risk. Experian builds it using a statistical model trained on the behaviour of businesses that have failed and businesses that have not, so the score is really a probability dressed up as a number.
It is worth being clear about what it predicts. The score is not a judgment of how profitable or well run your business is in your own eyes. It predicts the likelihood of serious payment default or insolvency within the next year, based on the data filed about your company. A profitable business with late accounts and a recent County Court Judgment can score worse than a leaner business with a clean, consistent record.
Worth knowing. There is also a Delphi score for sole traders and very small businesses that blends commercial and personal credit data. If you trade as a limited company, the commercial Delphi score is the one most lenders will pull first.
What Counts as a Good Delphi Score
Lenders group the score into broad risk bands. The exact cut-offs differ between funders, but the general picture is consistent across the market.
91 to 100 — very low risk, and 81 to 90 — low risk. Treated as a strong, lendable profile by most mainstream funders.
51 to 80 — below-average risk. Usually lendable, though terms may tighten towards the lower end.
26 to 50 — above-average risk. Workable with the right lender, often at a higher cost or with security.
0 to 25 — high to maximum risk. Mainstream unsecured lending is unlikely; specialist or asset-backed routes become the realistic option.
If your business sits below 50, that does not mean finance is off the table. It means the choice of lender matters enormously, because some funders weigh the Delphi score far more heavily than others. This is exactly where understanding the score before you apply protects you from a string of declines.
How Lenders Actually Use the Score
A common misconception is that the Delphi score is a pass-or-fail gate. In reality, most lenders use it as a filter and a pricing input rather than a single yes or no. A high score can take you straight into the best tier of an application, while a low score routes the file to manual review or a different product entirely.
The score also influences the limit a lender is willing to offer and the rate attached to it. Two businesses asking for the same facility can be offered very different terms purely because of where they sit on the scale. For unsecured lending and revolving facilities, the score carries the most weight. For secured or asset-backed lending, the underlying asset softens its impact, because the lender has something to recover if things go wrong.
Lenders read the score alongside your filed accounts, payment behaviour, sector, and director history. Where the picture is mixed, a clear explanation and well-prepared figures can shift a borderline decision. A blank application with a borderline score rarely gets the benefit of the doubt.
What Drives the Score Up or Down
The model draws on several categories of data. Knowing which levers you can actually pull is the difference between worrying about the score and improving it.
Payment performance
How promptly you pay suppliers and existing finance is one of the strongest signals. Consistent late payment, even where no formal action follows, drags the score down. Experian collects payment data from suppliers and lenders, so this is visible whether or not you realise it.
Filed accounts
Late or abbreviated accounts limit the data the model can see, and a model with less information defaults to caution. Filing full accounts on time gives the score more to work with and signals stability.
County Court Judgments
An unsatisfied CCJ is one of the heaviest negative factors. Even a settled judgment leaves a mark, though settling it is materially better than leaving it open. We cover this in detail in a separate article on how a CCJ affects a business loan application.
Age, structure, and sector
Older businesses with a settled structure tend to score better than very new ones, simply because there is more track record to assess. Industry risk also feeds in, so two identical balance sheets in different sectors can score differently.
A trap to avoid: multiple hard credit searches in a short window can pull the score down and signal distress to lenders. Applying to several funders directly, one after another, is one of the most common self-inflicted wounds we see.
Practical Steps to Improve Your Delphi Score
There is no overnight fix, and anyone promising one should be treated with caution. The model rewards consistent behaviour over time, so the work is steady rather than dramatic. The good news is that the same habits that improve the score also make the business more resilient.
Pay suppliers and existing finance on or before the due date, every time. This is the single most influential factor you control.
File full statutory accounts promptly rather than at the last minute, and avoid abbreviated filings where you can.
Settle any outstanding CCJs and keep evidence of satisfaction, then check the judgment is correctly marked on your file.
Check your own commercial credit file for errors. Mistakes in filed data are more common than owners expect, and correcting them can lift a score quickly.
Avoid scattergun applications. Consolidate your search through a broker who can approach the right lenders without leaving a trail of hard searches.
The strategic point: improve the score before you need to borrow, not when you are already under pressure. A score worked on six months ahead of an application is worth far more than a rushed attempt the week before.

Frequently Asked Questions
What is a Delphi score?
The Delphi score is a commercial credit score produced by Experian that predicts how likely a business is to fail or fall seriously behind on payments over the next twelve months. It runs from 0 to 100, with a higher number indicating lower risk. Most UK business lenders use it as a starting point when assessing an application.
What is a good Delphi score for a business?
Experian bands 91 to 100 as very low risk, 81 to 90 as low risk, 51 to 80 as below-average risk, 26 to 50 as above-average risk, and 25 or below as high risk. The exact thresholds vary by lender and by the type of facility, but most mainstream lenders want to see a score comfortably above 50 before they will consider lending on standard terms.
How can I check my company's Delphi score?
You can check your company's Delphi score directly through Experian's business credit reporting service, or ask a finance broker to review it with you as part of assessing your funding options. Checking your own file does not damage your score, so it is worth doing before you approach any lender.
How is a Delphi score calculated?
The score combines filed accounts, payment performance data, any County Court Judgments, the age and structure of the business, director information, and industry risk. Experian weights these factors using a statistical model that predicts the likelihood of business failure or serious payment default within twelve months.
How long does it take to improve a Delphi score?
There is no instant fix. Paying suppliers and finance on time, filing full accounts promptly, settling any judgments, and avoiding unnecessary credit searches all help, but the model rewards consistent behaviour over months rather than days. A realistic improvement window is three to twelve months, which is why it pays to address it before you need to borrow.
Can I still get business finance with a low Delphi score?
Yes, but your options narrow and the cost usually rises. Some lenders specialise in higher-risk profiles, and secured or asset-backed facilities are less dependent on the score than unsecured lending. A broker who understands which lenders weigh the Delphi score most heavily can position the application with the right funder rather than collecting declines.
