Bad credit mortgages explained

A bad credit mortgage is a mortgage for someone with problems on their credit file. Here is how lenders see defaults, CCJs and missed payments, how long they matter, and a checker for where you stand today.

Quick answer

You can often get a bad credit mortgage. What matters most is how recent the problem is, whether it has been paid off, and how you have managed credit since. A satisfied default from three years ago may only narrow the choice a little; a recent unsatisfied CCJ usually means a specialist lender and a bigger deposit.

Most problems stay on your credit file for six years, and the choice of lenders widens as they age.

What counts as bad credit

Lenders look at missed payments, defaults, County Court Judgments, debt management plans, IVAs, bankruptcy, repossessions and recent payday loans. A low score on a credit app is not the same thing: each lender scores you its own way, using your credit file from the agencies Experian, Equifax and TransUnion, plus what you tell them.

How lenders see it

For a bad credit mortgage, recency matters most: something in the last year is treated very differently from something three years ago. Satisfied defaults and CCJs, meaning paid off, are viewed better than unsatisfied ones, and small amounts, under about £500, often matter less. Missed mortgage or rent payments are looked at most closely. A clean record since the problem helps, and so does a bigger deposit.

Does your credit score affect a mortgage?

Indirectly. Lenders do not use the score you see in an app; they use their own scoring and your full credit file. But the things that lower an app score, such as missed payments, high card balances and lots of recent applications, also count against you with lenders. A fair score does not stop you getting a mortgage; it may just narrow the choice.

How to improve your chances

Get your statutory credit report from all three agencies and challenge anything wrong. Register to vote at your address. Keep every payment on time from now on and bring card balances down. Avoid several applications at once, because each full search shows on your file. An adviser can check which lenders fit before any search is run.

Specialist lenders and advisers

Many lenders that consider recent credit problems only accept applications through brokers. Rates are usually higher at first, and many people remortgage to a mainstream deal once the problem ages. Your home may be repossessed if you do not keep up repayments on your mortgage. If you are struggling with debt now, MoneyHelper (moneyhelper.org.uk) can point you to free advice.

Common questions

Can I get a mortgage with bad credit?
Often, yes. How recent the problem is, whether it has been paid off and how you have managed credit since matter most. Specialist lenders cover most situations, usually with a bigger deposit.
How long does a default stay on my credit file?
Six years from the date it was registered, whether or not you pay it. Paying it off marks it as satisfied, which lenders view better.
Can I get a mortgage with a CCJ?
Yes, with some lenders. A satisfied CCJ from more than a couple of years ago is viewed much better than a recent unsatisfied one. If you pay a CCJ within a month, it can be removed from the register.
Does my credit score affect getting a mortgage?
Lenders use their own scoring and your full credit file, not the score in an app, but the same things count: missed payments, high balances and recent applications.
Will checking where I stand affect my credit file?
Not with this checker, which runs no search. A full mortgage application does leave a hard search on your file.
