Mortgage Arrears: The Complete Rescue Plan

Updated: February 2026 | Prepared by AgentSuite.uk Editorial Team

If you're a homeowner, it's not just the bricks and mortar that keeps the roof over your head, but your ability to repay the mortgage. Falling behind on mortgage repayments means you're in arrears—a situation that puts your home at risk of repossession. At AgentSuite.uk, we know this is a stressful time, but ignoring it is the only way to guarantee a bad outcome.

⚠️ NOT YET IN ARREARS? If you haven't missed a payment yet but are worried you might, please stop here and read our "Struggling to Pay" guide. That guide covers the Mortgage Charter which offers protection before the arrears clock starts ticking.

Understanding 'Mortgage Arrears'

In simple terms, 'arrears' is a build-up of overdue payments. When you miss your first payment, you are technically in arrears. It is a serious legal situation. In the UK, around 100,000 homeowners are currently in this position due to rising interest rates and the cost-of-living crisis.

Being in arrears damages your credit file for six years, making it nearly impossible to get a competitive mortgage rate or even a simple credit card in the future. At its worst, persistent arrears lead to repossession—where the lender takes legal ownership of your property to recover their debt.

Step 1

Contact Your Mortgage Lender Immediately

This is the most critical advice: Talk to your lender. Many people avoid this out of fear, thinking the lender will take the house faster. In reality, it’s the opposite. Lenders are regulated by the Financial Conduct Authority (FCA) and are legally required to treat customers fairly.

Reaching out to discuss your situation does NOT damage your credit score. It only shows you are responsible. Once you agree on a plan, your lender can offer 'Tailored Support' (Forbearance), which includes:

  • Reduced Repayments: You pay a fraction of the monthly cost for a set period.
  • Repayment Holidays: Stopping payments entirely for 1-3 months (only in extreme cases).
  • Capitalisation of Arrears: Adding your missed payments to the total mortgage balance so you can start fresh with normal payments (this increases your long-term debt).
  • Term Extension: Moving from a 20-year to a 30-year mortgage to lower the monthly burden.

Step 2

Claiming on Mortgage Insurance

Do you have Mortgage Payment Protection Insurance (MPPI)? Many people forget they opted for this when they first took their mortgage. It typically covers your payments for 12 to 24 months if you lose your job or fall ill.

Check for ASU (Accident, Sickness, and Unemployment) policies too. These don't pay out instantly—there is often a 'waiting period' of 30 to 90 days, so you must start the claim process the moment you think you might struggle.

Step 3

Government Support: SMI (Support for Mortgage Interest)

If you are on certain benefits (Universal Credit, JSA, ESA, or Pension Credit), the government can help. This is called SMI. It is not a "benefit" anymore; it is a loan that must be repaid with interest when the house is sold.

Key Facts about SMI:

  • It covers the interest on up to £200,000 of your mortgage.
  • The current interest rate they pay is 3.66%.
  • Wait Period: For Universal Credit, you usually have to wait 3 months before SMI starts. For other benefits, it’s often 39 weeks.
Step 4

Your Repossession Rights: The Law

Repossession is a last resort. Lenders cannot just change the locks. They must follow a 'Pre-action Protocol'. This means they must prove to a judge that they tried everything to help you before asking for a possession order.

The 12-Month Rule: Major UK lenders have agreed not to start repossession proceedings until at least 12 months have passed since your first missed payment, as long as you are trying to find a solution.

If you realize you simply cannot afford the house anymore, it is often better to sell the property yourself. A forced auction by a bank usually sells the house for 20-30% less than its market value, leaving you with no cash and a ruined credit history.

Step 5

Mental Health and Debt

Financial stress is a leading cause of mental health issues. If you are struggling with depression or anxiety due to arrears, you are entitled to extra protection. Under the 'Breathing Space' scheme, you can get 60 days of legal protection from creditors to sort out your mental health and finances without being hounded by calls.
