Owning a home can become financially challenging if your income suddenly falls because of unemployment, illness or retirement. If you’re worried about keeping up with your mortgage, you may have heard about Support for Mortgage Interest (SMI).
Many people assume it is a benefit that pays their mortgage. In reality, it works differently.
This guide explains exactly what Support for Mortgage Interest is, who can claim it, how much help is available, how to apply and what happens when you eventually sell your home.
All information has been reviewed against current UK Government guidance at the time of writing.
Support for Mortgage Interest (SMI) is a Government loan that helps eligible homeowners pay the interest on their mortgage or certain home improvement loans if they receive qualifying benefits.
Unlike many benefits, SMI is not free money. It is a loan secured against your property and usually has to be repaid, with interest, when your home is sold or ownership changes.
Support for Mortgage Interest helps homeowners who receive certain income related benefits meet the interest payments on their mortgage.
It is designed to reduce the risk of people losing their homes during periods of financial hardship.
SMI does not pay:
Instead, it contributes towards the interest on qualifying borrowing.

| Repayable | Yes |
| Interest charged | Yes |

If your qualifying benefit stops, your SMI payments usually stop as well.
Savings are not assessed directly for SMI itself.
However, because SMI depends upon receiving qualifying benefits, any savings that affect those benefits could also affect your eligibility for Support for Mortgage Interest.
For example:

| Savings below benefit limits | May remain eligible |
| Savings above benefit limits | Benefit may stop which could end SMI |
Always report changes in savings to the relevant benefit office.
The amount varies.
The Government calculates your payment using:
The payment is usually sent directly to your mortgage lender.
Remember:
SMI does not necessarily cover all of your mortgage interest if your lender charges a higher rate than the Government’s standard rate.
| Mortgage Interest | Government Support |
| Interest below standard rate | Usually fully covered |
| Interest above standard rate | You may need to pay the difference |
You do not usually submit a completely separate application at the beginning.

Support for Mortgage Interest provides valuable help for homeowners facing financial difficulties, but it is important to understand exactly how it works.
Unlike many other forms of financial support, SMI is a loan rather than a benefit. It can help protect your home by paying eligible mortgage interest while you receive certain qualifying benefits, but the money usually has to be repaid in the future.
Understanding the eligibility rules, application process and long term repayment obligations can help you make an informed decision about whether Support for Mortgage Interest is right for your circumstances.
If you are struggling with mortgage payments, seek advice as early as possible. Early action can often prevent more serious financial problems later.
