Defaulting on a mortgage
If you fall behind on your mortgage payments, it’s easy to feel overwhelmed by the situation.
But there are practical steps you can take to get yourself back on track.
What is a mortgage default?
If you miss one mortgage payment, you’re in arrears.
But if you fall two or more months behind, your lender will usually treat this as serious mortgage arrears and may begin taking further action.
This is sometimes referred to as a mortgage default.
What happens if you default on a mortgage?
Defaulting on a mortgage can have serious consequences.
At first, if you fall behind on your mortgage payments, your lender must contact you to discuss the missed payments and tell you exactly:
- how much you owe
- what payments you’ve missed
- any charges added
They must then try to agree a way forward with you.
If the situation continues, you may:
- be asked to make a plan to repay the arrears
- be charged extra charges and interest
Falling behind on your mortgage can also affect your credit file.
In more serious cases, your lender could start repossession proceedings.
We should stress though that your lender can’t repossess your home straight away and that this option is usually a last resort.

What should I do if I’m behind on my mortgage?
The first thing you should do is speak to your lender as soon as possible.
They may look at ways of reducing your monthly payments, such as switching to interest-only or extending your mortgage term.
Before speaking to your lender, think about
- what you can realistically afford to pay
- when your situation might improve
- how you could repay any missed payments
And in the meantime, pay as much as you can, even if you can’t afford the full payment.
Even paying some of what you owe is better than missing payments completely.
UK lenders are regulated by the Financial Conduct Authority and many will have signed up to the Mortgage Charter, which sets out additional support options for borrowers facing payment difficulties.
So they have a duty to treat you fairly and help you find a solution.
They must at least try to agree a solution before repossession and give notice before taking legal action.
