An adverse credit history is an unfavourable one, usually meaning your report contains negative markers — late or defaulted payments, CCJs, or a bankruptcy.

What adverse credit history is#

Your credit report is a CV of your financial history — a detailed record of your personal information and your borrowing and repayment history. Lenders use it to assess how likely you are to repay agreements they approve.

A report containing negative markers — late or missed payments, defaults, insolvencies, court judgments — is said to have an adverse credit history.

It means you haven't kept up with financial commitments in the past. Which can easily result from circumstances outside your control: a large unexpected bill, redundancy, illness.

What it looks like on your report#

Lenders tend to update your account information monthly, labelling each account with a marker showing its status. Ideally you and prospective lenders see payments made on time according to the terms of the agreement.

Where an account isn't paid on time, a negative marker may appear — and those markers are what constitute an adverse credit history.

Not all lenders report to all three agencies, so seeing Experian, Equifax and TransUnion together gives you a better idea of what a lender might actually see.

Payment markers to look out for#

Some markers are neutral, like U for Unclassified, used for a newly opened account with no activity yet. Others are viewed negatively:

  • Numbers 1 to 6, reflecting how many monthly payments have been missed — 1 for one, up to 6 for six or more.
  • AR — an arrangement to pay, where a lender agrees the borrower can pay a different amount each month than originally agreed. It may be short term or last until the account is settled. Lenders view it negatively, since it suggests the customer couldn't keep up with the original agreement.
  • D — a default, reported after missed payments over a prolonged period or a breach of the agreement's terms. The lender sends a Default Notice first and gives 14 days to pay the outstanding balance. Left unsettled, the default is added and the debt may pass to a debt collection agency, or court proceedings may begin. Unlike one missed payment, which lenders can accept as a temporary setback, a D signals that lending is highly risky.
  • DA — Debt Assigned, meaning the account has been sold to a debt collector.

Other entries to be aware of:

  • County Court Judgments — a court ruling enforcing debt repayment. Pay the debt in full within one month of issue, with a Certificate of Cancellation submitted to the court, and the judgment is set aside and removed. Otherwise a CCJ remains for six years.
  • Bankruptcy — people are usually released from restrictions and debts after 12 months (opens external site), but a bankruptcy remains on your report for six years, as long as you've been discharged.
  • Repossession — if you can't keep up with a secured agreement like a mortgage or car finance, the lender can repossess your home or car and sell it to recover what you owe. Recorded for six years.

How long it lasts#

Generally, six years.

Encouragingly, lenders are more interested in your recent borrowing history. So the negative impact diminishes over time if you go on to manage credit well.

During those six years you can build a positive history demonstrating responsible borrowing. And once the negative markers drop off, you should see an improvement as the positive history built up in the meantime replaces them.

The impact#

Since lenders rely on credit reports to assess how responsibly you manage credit, negative markers can be detrimental to applications. Each lender assesses differently, based on their own criteria.

Some won't reject outright but will offer stricter terms — a loan at a higher interest rate, or a credit card limit lower than you asked for.

Renting with adverse credit. Some entries, like a CCJ, are public records visible to prospective landlords. Since a CCJ signals previous financial difficulty, it can affect whether your application is approved.

Late or missed payments, arrears and defaults are only visible on your credit report, which landlords can't see without your permission. Though if you're signed up to a rent reporting scheme and your landlord is enrolled, previous missed rental payments may be visible.

Mortgage applications. Given the size of the commitment, lenders are more wary. Adverse credit doesn't make a mortgage impossible, but it reduces the number of lenders willing to approve you.

Specialist lenders offer bad credit mortgages, also called adverse credit or subprime mortgages. Expect a higher interest rate and possibly a bigger deposit — but they mean options exist.

How to check your history#

Look at your credit report. Each agency may hold different information, because some lenders don't have data sharing agreements with all three.

If you spot a mistake or inconsistency:

  • Contact the lender first. If you believe a negative marker is wrong, dispute it with the lender reporting it — you'll likely need evidence.
  • If that fails, raise a dispute with the agency. Both lenders and agencies have a legal obligation to hold accurate information. The agency will contact the lender to validate it, and a Notice of Dispute may be placed on your report meanwhile.

Common questions#

What is an adverse account?

One with a negative payment status — anything from a single late payment to a default, current or historic. The impact varies with the duration and value of the arrears.

How long does account history show?

Open accounts show a maximum of six years' repayment history. Closed accounts stay for six years from the date of closure — which means payments up to 12 years old could be displayed in the account history.

How do I improve my score?

Registering on the Electoral Roll, paying bills and credit commitments on time, monitoring your credit utilisation, and correcting errors. Growing a score is a long-term process taking months or years, and tends to happen at steady intervals across your life — opening a bank account, registering to vote, buying your first home.

The key things to remember#

  • Adverse credit means negative markers on your report, not a permanent state.
  • Markers run 1–6 for missed payments, AR for arrangement to pay, D for default, DA for debt assigned.
  • A CCJ paid in full within one month, with a Certificate of Cancellation, is removed.
  • Bankruptcy, repossession and CCJs all last six years.
  • Lenders weigh recent history most, so rebuilding starts immediately.
  • Adverse credit often changes the terms rather than blocking you entirely.
  • Specialist adverse credit mortgages exist, at higher rates and bigger deposits.
  • Closed account history can display payments up to 12 years old.
