Bad Credit Mortgages in the UK Explained
By Lauren Prescott, removals specialist with 15 years of industry experience · Updated January 2025
Adverse credit narrows your choice of mortgage lender rather than closing the door entirely. Specialist lenders price for risk, and that price generally falls as the credit issue becomes older and less recent, which means a larger deposit and the right broker often matter more than the problem itself.
The short answer
- Recent and large credit issues carry far more weight with lenders than older or smaller ones.
- A larger deposit is usually the single most effective way to access more lenders and a better rate.
- Checking your credit file for errors and avoiding new credit applications before applying both help.
- Specialist brokers have access to lenders that do not deal directly with the public, which matters for adverse credit cases.
- Direct applications to high street lenders often produce a decline that then sits on your credit file, so a broker is generally the safer route.
What counts as adverse credit
Adverse or bad credit covers a range of issues, including missed payments, defaults, county court judgments, individual voluntary arrangements and bankruptcy. Lenders do not treat these as a single category, they weigh each one by how recent it is, how large the amount involved was, and whether it has since been settled or remains outstanding.
How lenders actually assess it
A default from several years ago that has since been settled carries far less weight than a missed payment from the last few months, even if the more recent issue is smaller in value. Most specialist lenders set rules around how long ago an issue needs to have occurred before they will consider an application, and these thresholds differ meaningfully between lenders, which is part of why a broker with access to the whole specialist market matters.
| Issue | General lender approach |
|---|---|
| Missed payments | Weighted heavily by recency, less impact if older and infrequent |
| Defaults | Settled defaults viewed more favourably than unsettled ones |
| County court judgments | Size and whether satisfied both matter significantly |
| IVA | Specialist lenders only, usually after a minimum time has passed |
| Bankruptcy | Most restrictive, specialist lenders only, after discharge and a waiting period |
Improving your position before you apply
A number of practical steps genuinely improve how an application is viewed, even where the underlying credit history cannot be changed quickly.
- Check all three main credit reference agency files for errors and dispute anything inaccurate.
- Register on the electoral roll at your current address if you have not already.
- Keep credit utilisation low on any active cards or accounts in the months before applying.
- Avoid applying for new credit or increasing existing limits in the six months before a mortgage application.
- Build a track record of on time payments on any current credit commitments.
Deposit and interest rate
A larger deposit is generally the single most effective lever available to someone with adverse credit, since it directly reduces the lender's risk. A deposit in the region of fifteen to twenty five per cent typically opens access to a meaningfully wider range of specialist products and reduces the interest rate premium charged for the credit history, compared with the minimum deposit a lender might technically accept.
Why a specialist broker matters
Adverse credit lending is, in practice, a broker driven market. Many of the lenders who deal with more complex credit histories do not take applications directly from the public and only work through brokers, which means a direct approach to a familiar high street bank often results in a straightforward decline rather than a considered assessment.
A decline recorded by a lender can itself show up on your credit file and be visible to future lenders, so applying speculatively to several lenders without advice carries a real cost. A broker who specialises in adverse credit cases can match an application to lenders likely to accept it before it is formally submitted, which avoids this problem.
What to expect from the process
Expect to provide a fuller explanation of any credit issues than you would with a clean credit history, including when they occurred, why, and what has changed since. Lenders in this part of the market are generally more interested in understanding the full picture and current affordability than in treating any single historic issue as an automatic refusal.
Frequently asked questions
Can I get a mortgage with a default on my credit file?
Often yes, particularly if the default is settled and not recent. Specialist lenders assess the size, age and status of the default rather than refusing automatically.
Does bad credit mean I need a bigger deposit?
Usually yes. A larger deposit, commonly in the region of fifteen to twenty five per cent, opens access to more lenders and reduces the rate premium charged for adverse credit.
Should I apply directly to my bank if I have bad credit?
It is generally safer not to, since a decline from a high street lender can itself appear on your credit file. A specialist broker can identify suitable lenders before an application is submitted.
How long does a default affect my mortgage application?
Defaults generally remain on credit files for six years, but their impact on a mortgage application reduces well before that as the default becomes older, particularly once it is settled.
What is the most effective step to take before applying?
Check your credit files for errors, avoid new credit applications in the months beforehand, and speak to a broker who specialises in adverse credit mortgages before approaching any lender.
