If you are a homeowner on benefits and are struggling to pay your mortgage, you may be eligible for a **Support for Mortgage Interest (SMI)** loan. Unlike Housing Benefit, which covers rent, SMI is a government loan that helps cover the interest on your mortgage.
1. The 'Loan, Not Grant' Structure
Since 2018, SMI has been a loan. You must pay it back with interest, but only when you sell your home, transfer ownership, or die.
Technical Rule: The interest rate on the SMI loan is usually linked to the BoE base rate but is currently capped at a specific government calculation. In 2026, the current SMI interest rate is 3.75% (subject to quarterly reviews).
🚀 The Hustler's Strategy: The '3-Month Bridge'
The biggest trap in SMI is the waiting period.
Keyword Strategy: You usually have to wait **3 consecutive assessment periods** (roughly 3 months) on Universal Credit before you can get SMI. Strategic Move: As soon as you apply for UC, contact your mortgage lender and request a "Payment Holiday" or a switch to "Interest-Only" payments for 3 months. Tell them you have applied for SMI. Most lenders are familiar with the DWP's 3-month wait and will agree to temporary measures to prevent arrears.
2. What Can SMI Pay For?
SMI can help pay the interest on:
- A mortgage on the home you live in.
- Loans for home repairs or improvements that are "essential" (e.g. roof repairs).
Note: SMI will NOT pay for the capital repayment of your mortgage, your house insurance, or your council tax.
3. The £200,000 Limit
The DWP will only pay interest on up to **£200,000** of your mortgage (or £100,000 if you are on Pension Credit). If your mortgage is higher than this, you must cover the remaining interest yourself.
SMI FAQs
Can I get SMI if I have a job?
No. If you have any earnings from work (even £1), your SMI will stop. It is only for those with zero earned income on Universal Credit (or those on Pension Credit/Legacy Benefits).
Can I pay the loan back early?
Yes. You can make voluntary repayments of £100 or more at any time to reduce the amount of interest you will owe when you eventually sell your home.
