Impaired credit describes a credit file that includes one or more negative entries, such as missed payments, defaults, a CCJ, mortgage arrears, or a more serious step like an IVA or bankruptcy. It’s not an official category set by any regulator or credit reference agency. It’s an industry term, used by lenders, brokers and specialist advisers (including us) to describe files that need a different approach to a completely clean one.
If you’ve been told your credit is “impaired”, it usually means something specific is showing on your file, not that your finances are permanently unworkable.
Where the term comes from
Mortgage and lending markets have long split borrowers informally into groups based on their credit history: those with a clean file, sometimes called prime, and those with negative entries, often grouped under impaired, adverse or non-standard credit. This grew out of how lenders built different products and pricing for each group, rather than from any single legal definition. You’ll see “impaired credit”, “adverse credit” and “bad credit” used interchangeably across the industry, including on this site, and none of them means anything more precise than the others.
What typically counts as impaired credit
There’s no fixed checklist, but the entries most commonly described this way include:
- Late or missed payments on loans, cards, mortgages or household bills
- Defaults, recorded once a lender treats an account as broken down
- County court judgments (CCJs), a court order to repay a debt
- Mortgage arrears, missed payments specifically on a secured loan
- Debt management plans, an informal arrangement with creditors
- IVAs, protected trust deeds, bankruptcy or sequestration, the more formal insolvency routes
Our guide on what is adverse credit covers each of these types in more depth if you’re not sure which applies to your situation.
How impaired credit is actually assessed
“Impaired” isn’t a single grade. Lenders and advisers typically look at several things together to work out how significant an entry is likely to be to a particular application.
| Factor | Why it’s assessed |
|---|---|
| Type of entry | Mortgage arrears, an IVA or bankruptcy are generally viewed more seriously than a single late phone bill |
| How recent it is | An issue from several years ago usually carries less weight than one from the last 12 months |
| Whether it’s settled | A satisfied CCJ or settled default may be viewed differently from an unresolved one |
| How many entries | A single isolated issue is often viewed differently from a pattern of several |
| The rest of the file | A clean record since the issue happened can matter as much as the issue itself |
This is a general pattern, not a fixed scoring system. Individual lenders set their own criteria and can weigh these factors quite differently from each other.
Impaired credit as a lending market, not just a description
You’ll also see “impaired credit” used to describe a segment of the mortgage market itself, sometimes called adverse credit or specialist lending, made up of lenders and products designed for borrowers whose files don’t fit typical mainstream criteria. This is a separate use of the term from describing your own file, but the two are closely linked, since it’s this part of the market that a broker or adviser is likely to look at first if your file includes anything significant.
Being pointed toward this part of the market isn’t a judgement on you personally. It reflects how lenders build risk-based pricing and criteria, not a comment on your character or your ability to manage money going forward.
What impaired credit tends to mean in practice
A few general patterns are worth knowing, while remembering that individual lender criteria vary and can change at any time:
- Rates for adverse credit are often higher than typical high-street rates, reflecting the additional risk a lender is taking on. No one can quote you a figure without assessing your actual circumstances.
- Fewer lenders may be available, particularly for more serious or more recent entries, though this narrows the field rather than closing it entirely.
- A specialist adviser may be more useful than going direct, since they can compare products designed with adverse credit in mind. Our guide on whether you need a broker for a bad credit remortgage covers what that involves.
- It’s rarely permanent. Entries age, become settled, and eventually drop off your file after 6 years, and lenders often view older or resolved issues more favourably than fresh ones.
What this means if you’re remortgaging with impaired credit
If you’ve been told your credit is impaired, or you can see negative entries on your own report, the practical next step is understanding exactly what’s there rather than the label itself. Get your statutory credit report free from Experian, Equifax and TransUnion, and note the type, date and status of each entry.
From there, our page on remortgaging with a low credit score looks at the wider picture, and specific pages such as remortgaging with a CCJ or remortgaging with defaults go into detail for particular entries. Our guide on what credit score you actually need for a mortgage explains why the label matters less than what’s actually recorded.
If your credit issues are tied to wider financial difficulty rather than a one-off event, free and impartial help is available from MoneyHelper, StepChange and National Debtline before you take on any new borrowing.
Frequently asked questions
Is impaired credit the same as bad credit?
They're used to mean much the same thing. 'Impaired credit', 'adverse credit' and 'bad credit' all describe a file that includes negative entries, such as missed payments, defaults, CCJs, or an IVA or bankruptcy. None of these are official categories; they're informal terms used across the industry, including by us.
Does impaired credit mean I can only use specialist lenders?
Not always. It depends on the type, age and severity of what's on your file, plus your income, outgoings and loan-to-value. Some mainstream lenders do consider certain adverse entries, particularly older or settled ones, while others focus more on specialist adverse credit lending.
Will impaired credit mean higher rates?
Rates for adverse credit are often higher than typical high-street rates, since lenders price for the additional risk they're taking on. The exact difference depends on the lender, the severity of what's on your file, and your loan-to-value, so nobody can quote a figure without looking at your circumstances.
Can impaired credit improve over time?
Yes, in the sense that entries age and eventually drop off your file after 6 years, and a settled or older issue is often viewed differently to a recent, unresolved one. Impaired credit isn't necessarily permanent, even though it can feel that way while it's current.
