Quick answer
UK business credit scores are driven by Companies House filing history, trade-credit payment behaviour, accounts filed on time, public records like CCJs, and the age and stability of the company. Improving the score is mostly about doing the boring things consistently for six to twelve months: file on time, pay suppliers on time, keep accounts current, and avoid public records. Score changes are gradual, not instant.
What the bureaus actually look at
The main UK commercial credit bureaus - Experian, Equifax and Creditsafe - score limited companies on a mix of public and private data. Public data includes Companies House filings (confirmation statement, accounts, charges register), CCJs, winding-up petitions and insolvency events. Private data includes payment behaviour reported by suppliers, banks and finance providers who share data with the bureau.
Each bureau weighs these differently, which is why the same company can have meaningfully different scores at each. Lenders typically know this and look at the underlying signals more than the headline number.
What moves the score in a useful direction
File your accounts and confirmation statement on time, every time. Late filings are one of the biggest drag factors. If accounts are due in three months, do not leave them to the last week - a small delay can hit the score even before the actual deadline passes.
Pay trade suppliers within agreed terms. Suppliers who report data to bureaus include this in your file. A company that consistently pays within thirty days looks materially better than one that drifts to sixty or seventy. If terms are a problem, renegotiate them rather than missing them.
Resolve CCJs quickly. A satisfied CCJ shown on the file is much better than an unsatisfied one, and after six years a CCJ drops off the file entirely. If a CCJ is wrong, contest it; if it is right, pay it and apply for the satisfaction certificate.
What does not move the score (or moves it the wrong way)
Lots of credit applications in a short window can lower scores at some bureaus, particularly when they each generate a hard search. Spreading applications and using soft-search products where available helps.
Frequent changes to registered office, directors or PSC information can be a small negative, particularly if the company is young. Stability is a positive signal in the model.
Personal-credit improvements do not move the company score directly, though they help when a personal guarantee is in play. The two files are scored separately.
How long it takes
Most score improvements take three to twelve months to be reflected meaningfully. A single clean filing or a satisfied CCJ can move the needle within a quarter; a track record of paying suppliers on time takes longer to build because the bureau needs multiple data points before the pattern is statistically meaningful.
Check your file every quarter while you are working on it. Bureaus will give a free or low-cost copy of the data they hold; some offer a monitoring subscription. The point is not the headline score, it is whether the underlying signals are moving.

Frequently asked questions
- Which bureau matters most?
- It depends on the lender. Larger UK lenders often look at Experian, but many use Equifax or Creditsafe instead. Lenders typically check more than one source for larger deals.
- Can I improve my score quickly before applying?
- Some things can be fixed in days (errors, late filings, satisfying a CCJ). The underlying pattern of behaviour takes months to shift.
- Does paying off a business loan improve the score?
- Settling a facility on time and as agreed is a positive signal. Early settlement is usually neutral - it does not necessarily improve the score.
- Do dormant or new companies have a score?
- Often the score is thin or unscored. Lenders typically rely more on director-level signals and operational data in those cases.
