Building Society Mortgage Arrears: What to Do When You Cannot Afford Your Payments
If you have missed a mortgage payment to your building society, or know you will struggle with the next one, contact your lender’s mortgage payment support team as soon as possible. You do not need to wait until you are several months behind.
UK building societies can consider different forms of support, including temporary payment reductions, interest-only arrangements, longer mortgage terms and affordable arrears repayment plans. What is suitable depends on your finances and the type of mortgage you have.
This guide explains your next steps, what lenders must consider, how the 2026 Mortgage Charter works, where to get free debt advice and what to do if repossession proceedings have started.

Mortgage Arrears Help: Quick Answers
What to Do Immediately if You Cannot Pay Your Mortgage
If the next payment is unaffordable, the objective is to contact the lender, understand the shortfall and agree a realistic next step. You can start this process before any payment is missed.
- Contact the building society. Ask for its mortgage payment difficulties or arrears team. Use the telephone number shown on the lender’s official website or your mortgage statement.
- Explain what has changed. Mention reduced working hours, job loss, illness, relationship breakdown, increased household costs or another relevant change.
- Ask for the exact amount owed. Request the normal monthly payment, missed amounts, total arrears, charges and next payment date.
- Prepare a realistic household budget. Work out income, essential spending and what you can sustainably put towards the mortgage.
- Discuss support arrangements. Ask whether temporary payment reductions, changes to the mortgage term or another suitable option could help.
- Request written confirmation. Check the start and end dates, payment amount, arrears treatment, interest consequences and potential credit-file reporting.
- Contact a free debt adviser. This can help if other debts, council tax, energy bills or essential expenses are also becoming unmanageable.
- Review the arrangement. Inform the lender promptly if your circumstances change or you cannot keep to the agreed plan.

What Counts as Mortgage Arrears?
Mortgage arrears arise when you have not paid an amount due under your mortgage agreement. This may involve a completely missed payment or a payment that is less than the amount required.
For example, if your contractual mortgage payment is £950 and you pay only £600 without an agreed arrangement, you may have a £350 payment shortfall.
Example: Two Missed Mortgage Payments
This example excludes any interest or charges that might apply. The lender’s account statement is the correct source for your actual balance.
What Happens After the First Missed Payment?
Your building society will usually attempt to contact you and establish why the payment was missed. It should provide relevant arrears information and consider whether an appropriate repayment arrangement can be agreed.
Under FCA MCOB 13 rules, regulated mortgage lenders have specific obligations to provide information about payment shortfalls, outstanding debt and charges. They must also treat customers experiencing or approaching payment difficulties fairly.
What to Prepare Before Calling the Building Society
You do not need a perfect budget before making first contact. However, a few details can help the adviser understand the problem and suggest an affordable arrangement.
“I’m concerned that I won’t be able to meet my next mortgage payment. My circumstances have changed, and I want to discuss what support might be available before I fall further behind. I can explain my income and essential costs and would like to agree a payment arrangement I can afford.”
If you have already missed a payment, say so and ask for an up-to-date arrears statement. If you need an interpreter, accessible communication, longer appointment or help from a trusted representative, tell the lender.
What Mortgage Payment Support Can Building Societies Offer?
Under the FCA’s mortgage payment-difficulties rules, lenders must consider a range of appropriate support options. The exact arrangement depends on your circumstances, mortgage terms and affordability.

2026 Mortgage Charter: What Support Does It Provide?
The UK government published an updated Mortgage Charter on 26 March 2026. It sets out additional commitments by participating lenders to support mortgage borrowers facing higher payments.
One important distinction is whether you are still up to date with your mortgage or have already fallen into arrears.
Eligible borrowers with participating lenders may request a one-off six-month switch to interest-only payments or extend the mortgage term to reduce monthly payments.
Qualifying borrowers can ask to return to their original mortgage term within six months, subject to the Charter’s conditions.
The streamlined Charter options for customers up to date with payments are not automatically available. You should instead work directly with the lender’s specialist payment-support team.
Participating lenders commit not to force borrowers to leave their home within 12 months of the first missed payment unless exceptional circumstances apply.
Does the Charter Affect Your Credit Score?
Under the Charter, eligible borrowers who are up to date with payments can use the specified temporary support options without a new affordability assessment or an adverse credit-score impact from taking those options as described.
This protection should not be confused with missed payments, arrears or other tailored arrangements, which can have different credit consequences.

How to Agree an Affordable Mortgage Arrears Repayment Plan
A repayment plan normally covers your ongoing contractual payment and an additional amount towards arrears. The lender should consider whether your proposal is realistic.
Example: Repaying £1,200 of Mortgage Arrears
If you could afford your normal £900 payment plus an additional £100 each month, the £1,200 shortfall could be repaid in approximately 12 months, assuming no further arrears, additional interest or charges.
The essential question is whether £1,000 per month is genuinely sustainable. If it leaves insufficient money for food, energy, travel to work or other essential costs, the proposal may fail.
These amounts are illustrative and do not constitute a recommended repayment plan. Your lender must assess your actual account and circumstances.
Questions to Ask Before Agreeing
Will Mortgage Arrears Affect Your Credit File or Add Charges?
Mortgage payment history can be reported to credit reference agencies. Missed payments may make future borrowing more difficult, even if you later clear the shortfall.
Some formal payment arrangements may also be reflected on your credit file. The reporting depends on the specific arrangement and the lender’s obligations.
Contacting the lender to discuss possible support does not itself mean a mortgage payment has been missed.
The shortfall may be reported according to the lender’s credit-reporting practices.
Ask how payments and the arrangement will be reported before accepting the proposed terms.
Request a breakdown of charges. FCA rules restrict inappropriate arrears charges, and charges should reflect the relevant permitted costs.
Government Help With Mortgage Payments: Support for Mortgage Interest
Some UK homeowners receiving qualifying benefits may be eligible for Support for Mortgage Interest, usually called SMI.
SMI is a loan that helps towards eligible mortgage interest. It is not a grant and does not normally cover mortgage capital repayments or existing arrears.
Current eligibility can include Universal Credit, Pension Credit and certain qualifying income-related Employment and Support Allowance circumstances.
SMI is calculated using government rules and a standard interest rate, which can differ from the rate on your actual mortgage.
The SMI loan is normally repaid with interest when you sell or transfer ownership of the property, subject to the applicable rules.
SMI does not clear existing missed payments. You must still agree suitable arrears arrangements with the mortgage lender.
Official UK governmentGOV.UK: Support for Mortgage Interest
After opening this link:
- Read the overview to understand that SMI is a repayable loan.
- Select “Eligibility” and check whether your qualifying benefit and mortgage meet the rules.
- Open “What you’ll get” to check the calculation and amount of interest potentially supported.
- Read “How to apply” for the current application procedure.
- Check “Repaying your loan” before accepting an SMI offer.
- Tell your lender if you apply, especially if the application is still being processed.
What if You Have Mortgage Payment Protection Insurance?
Check whether you have an income protection policy, mortgage payment protection policy or another insurance arrangement that may apply after unemployment, illness or incapacity.
Read the eligibility conditions, exclusions, waiting periods and claim deadlines. Tell the insurer promptly if you may have a valid claim.

Can a Building Society Repossess Your Home for Mortgage Arrears?
Repossession is a serious possible consequence of unresolved mortgage arrears, but it should be a last resort.
FCA rules require regulated mortgage lenders to make reasonable efforts to resolve payment difficulties and consider appropriate alternatives before taking possession.
How Mortgage Repossession Can Develop
- Missed payments: the borrower falls behind with contractual mortgage payments.
- Lender contact: the building society contacts the borrower and seeks information about their financial circumstances.
- Support discussions: appropriate options such as payment arrangements or other mortgage changes are considered.
- Formal notice and court action: if the problem remains unresolved, the lender may begin the relevant possession process.
- Court paperwork: the borrower receives documents explaining the claim and any hearing arrangements.
- Possession hearing: the court considers the case and what order, if any, should be made.
- Further enforcement: if legal conditions are met, possession may eventually be enforced.
What Does the 12-Month Mortgage Charter Commitment Mean?
Participating lenders have committed not to force a borrower to leave their home without consent within 12 months of the first missed mortgage payment except in exceptional circumstances.
This does not remove the mortgage debt, prevent interest or arrears from accumulating, or mean borrowers should ignore court correspondence.

Mortgage Arrears Rules Across England, Wales, Scotland and Northern Ireland
FCA mortgage regulation covers relevant regulated lending across the UK. However, court processes, debt protections, housing support and repossession procedures are not identical in every UK nation.
What if Your Building Society Refuses to Help or Handles Arrears Unfairly?
If you believe your lender has ignored relevant information, charged inappropriate fees, failed to explain an arrangement or treated you unfairly, you can make a formal complaint.
Explain what happened, what help you requested, what response you received and why you believe the lender’s actions were unreasonable.
- Ask for clarification. Request the reason why a proposed arrangement was rejected.
- Make a formal complaint. Use the building society’s official complaints process.
- Provide evidence. Include statements, budgets, correspondence and dates of discussions.
- Explain the requested remedy. For example, reconsideration of an affordable proposal, correction of an account error or review of a charge.
- Consider external escalation. If the matter remains unresolved or the applicable response period has expired, check whether the Financial Ombudsman Service can consider it.

Common Mortgage Arrears Mistakes to Avoid
Support can be easier to arrange when you first recognise the difficulty rather than after several payments have been missed.
An unrealistic plan can fail quickly. Use an honest budget and ask for an arrangement you can maintain.
Mortgage arrears can exist alongside council tax, energy and other urgent household liabilities. Free debt advice can help prioritise them appropriately.
Temporary payment relief must be agreed under the relevant lender rules. Skipping a payment without agreement can create arrears.
Support for Mortgage Interest helps with eligible interest as a repayable loan; it does not simply cancel existing missed mortgage payments.
Failure to respond or attend can seriously harm your position. Seek legal or housing advice as soon as legal action begins.

Building Society Mortgage Arrears FAQs
1. What should I do if I miss a building society mortgage payment?
Contact your building society’s mortgage arrears team as soon as possible. Ask for your current arrears balance, explain why the payment was missed and discuss an affordable repayment arrangement or other appropriate support. You can also obtain free independent debt advice.
2. Can my building society reduce my mortgage payments temporarily?
Possibly. Depending on your circumstances and mortgage terms, the lender may consider reduced payments, a temporary interest-only arrangement, term extension or another suitable form of support. The long-term interest cost and credit-file consequences should be explained before you agree.
3. Can I get an interest-only period if I am already in arrears?
A lender may consider temporary interest-only payments as part of tailored arrears support, but approval is not automatic. The streamlined Mortgage Charter option is intended for eligible borrowers who are up to date with payments. Borrowers already in arrears should contact the lender’s specialist support team.
4. Does the Mortgage Charter stop repossession for 12 months?
Participating lenders commit not to force borrowers to leave their home within 12 months of the first missed payment except in exceptional circumstances. This does not cancel mortgage payments, prevent arrears from growing or automatically stop all court proceedings.
5. Will missed mortgage payments affect my credit score?
Missed mortgage payments can be reported to credit reference agencies and may affect future borrowing. The credit impact of an agreed support arrangement depends on the type of arrangement and how it is reported. Ask the lender for an explanation before accepting revised payment terms.
6. Can my building society add arrears to the mortgage balance?
It may consider capitalising arrears where appropriate. This means adding the shortfall to the mortgage debt rather than requiring separate immediate repayment. The arrangement can increase the balance owed and future interest, so the lender should explain the consequences.
7. Can I get government help to pay mortgage arrears?
Eligible homeowners receiving qualifying benefits may be able to obtain a Support for Mortgage Interest loan towards eligible mortgage interest. SMI is repayable with interest and does not directly clear existing mortgage arrears. Discuss missed payments separately with your lender.
8. Where can I get free mortgage arrears advice in the UK?
MoneyHelper, StepChange, National Debtline, Citizens Advice and specialist housing organisations can provide free guidance or debt advice. If repossession proceedings have started, seek housing legal advice appropriate to your UK nation.
9. Can I complain if my building society refuses an affordable repayment plan?
Yes. Ask the lender to explain its decision and use its formal complaints process if you believe you have been treated unfairly. You may be able to refer the matter to the Financial Ombudsman Service if eligible. A complaint does not automatically pause mortgage payments or legal proceedings.
10. Can I lose my home after one missed mortgage payment?
One missed payment does not normally lead directly to immediate repossession. Regulated lenders must consider appropriate support and treat repossession as a last resort. However, mortgage arrears are serious, and you should contact the lender promptly rather than assuming a particular period of protection guarantees your home is safe.
