The six months before you apply matter more than most people realise

During this window, lenders look closely at how you've managed money recently. Some of that is within your control. This guide sets out what to check, what to fix, and what to leave alone.

What the run-up to an application is for

The six months before you apply are not a waiting period. They are the stretch a lender looks at most closely, because recent conduct tells an underwriter more than almost anything else on the file. The date of a CCJ or default is fixed: nothing you do now moves it earlier or later. But how you have managed money in the months right before you apply is something within your control, and it carries real weight in how a specialist lender reads the rest of the application.

Check what your file actually says

Start by getting a full copy of your credit file. Errors happen: a default marked as unsatisfied years after it was paid, a CCJ still showing when it should have dropped off. A soft search, one that leaves no mark other lenders can see, does not affect your score, so there is no cost to checking early and checking again closer to the time you plan to apply.

Keep the recent conduct clean

A missed payment in the last six to twelve months suggests present difficulty to an underwriter. If you have direct debits running for existing credit, utilities, or a phone contract, keeping every one of them on time between now and application does more for your position than almost anything else you can do in this window.

Leave new credit alone

Avoid taking out new credit, opening a credit card, or running several hard searches while comparing deals. Each hard search leaves a mark on the file, and a cluster of them in a short period can look like financial pressure to a lender, whatever the actual reason behind it.

Build what deposit you can

A larger deposit lowers the loan-to-value ratio (LTV), the share of the property's value you are borrowing. A lower LTV gives a specialist lender more room to work with, because it reduces what they stand to lose if things go wrong later. It will not offset a very recent, unsatisfied CCJ on its own, but alongside clean recent conduct it strengthens the application as a whole.

Satisfy what you can afford to

If you still have an outstanding default or CCJ, paying it off and having it marked as satisfied is worth doing where you can afford it. Some lenders treat a satisfied mark more favourably than the same debt left open, even when the satisfaction is recent. Whether it is worth prioritising over saving toward a deposit depends on your own timeline and the lender you eventually approach, so this is one to weigh against your other options rather than assume.

None of this guarantees an outcome. What it does is put the parts of your file that are within your control in the best order they can be before an underwriter looks at the rest. The eligibility tool walks through how different types of adverse credit are typically assessed, and the glossary is worth a look if any of the terms here, LTV, satisfaction, hard search, are new to you.

How the six months actually works

The run-up to application, stage by stage

A mortgage application is a single moment, but a lender is reading months of history behind it. Some of what they see is fixed, like the date a CCJ was registered or the amount a default was for, and no amount of preparation changes it. Other parts, mainly your conduct in the run-up to applying, are still being written, and this is where the six months does its work.

Pull your credit file and read what's actually on it

Every lender starts from the same document: your credit file, the record held by agencies such as Experian, Equifax and TransUnion of what you owe and how you've paid it. Get a copy from all three, because they don't always hold identical information, and read it properly. This is where you find out whether a CCJ has genuinely been satisfied, whether a default is showing the date you remember, and whether anything on it is wrong.

The file matches what you expected
You already know the shape of your situation, so the rest of the six months is about conduct and paperwork.

Something is wrong or unfamiliar
Raise a dispute with the credit reference agency directly. This can take weeks to resolve, so it's worth doing as early in the six months as possible.
Separate what's fixed from what you can still affect

The date a CCJ was registered, the amount a default was for, and whether a debt management plan (DMP) is still active are fixed facts. A lender will see them exactly as they are, and nothing you do now changes them. What you can affect is what happens next: paying off and satisfying a CCJ or default where you can afford to, and making sure any DMP or IVA payment due before you apply is never late.

Whether satisfying an old debt actually helps your case depends on the lender and how they weight it against age and size. It's rarely a wasted step, but it isn't a fixed rule either.
Build a clean run of payment conduct

Specialist lenders weigh recent behaviour heavily, and many look specifically at the months immediately before an application for missed payments, unauthorised overdraft use, or bounced direct debits. A single missed payment inside this window can carry more weight in underwriting, the lender's process for checking you against its lending criteria, than an older and larger default. Setting up direct debits for every regular commitment removes the risk of something being missed by oversight.
Get your paperwork and deposit evidence ready

Underwriters ask for proof, not just figures: several months of bank statements, payslips, proof of where your deposit came from, and an explanation for any large or unusual transactions. A deposit that's sat in the same account for months is easier to evidence than one that arrived as a lump sum shortly before you apply, because a lender will want to know its source. Gathering this early means you're not assembling it under time pressure once a lender is already looking at your file.
Use a soft search before committing to a hard search

A soft search, a check on your file that leaves no mark other lenders can see, lets a broker or lender give an early view of what might be available. A hard search, the formal application-stage check that is visible to other lenders and can affect your file, should come later and ideally only once, because several close together can itself read as financial stress to an underwriter.

Soft search suggests a workable path
You move into a fuller conversation with a specialist lender or a broker who works with them, with a clearer idea of what they'll want to see.

Soft search suggests limited options right now
That's still useful information. It usually means more time, more clean conduct, or a larger deposit would change the picture.

This sequence describes how lenders generally read the period before an application. It isn't a guarantee of any outcome, and which factors carry the most weight depends on the individual lender and what's actually on your file.

Work out your credit type

A CCJ, a default, a DMP and an IVA are assessed differently, so start by pinning down exactly what's recorded and when it happened.

What you do in the next six months is still within your control

The type of adverse credit you have is fixed, but your payment conduct, your credit file, and your paperwork over the coming months are not. Use that time deliberately.
