Support for Mortgage Interest: Waiting Period and Limits

If you are a homeowner on certain benefits and struggling with your mortgage, Support for Mortgage Interest can pay some of the interest for you. It is a loan, not a benefit, so it has to be paid back with interest when you sell or transfer your home. Here is who qualifies, how long you wait, and what it covers.

Support for Mortgage Interest: Waiting Period and Limits
Short answer

If you are a homeowner on a low income and struggling to keep up with your mortgage, Support for Mortgage Interest (SMI) can pay some of the interest for you. It is not a benefit. It is a loan secured on your home, and it has to be repaid with interest when you sell, transfer ownership, or die1.

If you are a homeowner on a low income and struggling to keep up with your mortgage, Support for Mortgage Interest (SMI) can pay some of the interest for you. It is not a benefit. It is a loan secured on your home, and it has to be repaid with interest when you sell, transfer ownership, or die1.

SMI only pays the interest on your mortgage. It generally cannot be used to pay off the amount you borrowed, which is the capital2. It is usually paid directly to your lender3. The waiting period depends on which benefit you get: Pension Credit claimants can get SMI immediately, while Universal Credit claimants wait three months4.

The amount of mortgage interest that can be covered is capped. For most people the limit is £200,000, but for Pension Credit claimants and those who started claiming another qualifying benefit before January 2009, the limit is £100,0003. The loan is secured by a charge over your property, and interest continues to build up until it is repaid3.

SMI is a loan secured on your home, not a benefit

Support for Mortgage Interest is a government loan scheme that helps with the interest costs of mortgages and certain home loans4. It is offered as a repayable loan, and the loan is secured against your property7. Where the loan needs to be secured, the Department for Work and Pensions will place a charge, or in some cases a mortgage, over your property3.

This matters because it changes what happens when you sell. You will need to repay the loan as a lump sum with interest if you sell or transfer ownership of your home8. If you finish paying your mortgage, you will not need to repay your SMI loan unless you sell or transfer ownership3.

SMI can help towards mortgage interest payments for a mortgage, a loan to buy your home, or a loan to improve your home3. You may also be able to get payments towards the interest on loans you took out for essential repairs or improvements, or buying your ex-partner's share in your home if you have separated2. It cannot be used to pay mortgage arrears9.

Who can get SMI: the qualifying benefits

You may be eligible for SMI if you are a homeowner and get one of the qualifying income-related benefits3. These are Universal Credit, Income Support, income-based Jobseeker's Allowance, income-related Employment and Support Allowance, and Pension Credit1.

If you are a joint or sole owner and are claiming Income Support, income-based Jobseeker's Allowance, or Pension Credit, you may qualify7. You might still be able to get SMI if you apply for one of the qualifying benefits but cannot get it because your income is too high, and you will be treated as getting the benefit you applied for3.

There are exclusions. You cannot get Support for Mortgage Interest if you also receive Statutory Sick Pay, Statutory Maternity Pay, Statutory Paternity Pay, Statutory Adoption Pay, Statutory Shared Parental Pay, earnings from employment or self-employment, or a tax refund10. This means that if you are working or receiving statutory pay, SMI will usually not be available.

Waiting period: from Pension Credit start to 3 months on Universal Credit

The waiting period for SMI depends on which benefit you receive. Pension Credit claimants can get SMI immediately, from the date you start getting Pension Credit4. For Universal Credit claimants, the wait is longer.

You will get help after you have been getting Universal Credit for three consecutive months3. This is described as receiving Universal Credit continuously for three assessment periods, which is three months11. One source notes that you may have to wait up to 9 months before payments can be made if you receive Universal Credit, which reflects the time it can take for the claim to be processed and for payments to start7.

If you stopped getting income-related ESA and applied for Universal Credit within a month, SMI restarts straight away3. This is a specific rule for people moving between benefits.

Limits: interest on up to £200,000, or £100,000 in some cases

The amount of mortgage interest that SMI will cover is capped. If you are eligible, you will get help paying the interest on up to £200,000 of your loan or mortgage3. This is the standard limit for most claimants9.

There is a lower limit for some people. The figure is £100,000 if you get Pension Credit, or if you started claiming another qualifying benefit before January 20093. This means that Pension Credit claimants have a lower cap on the mortgage interest that can be covered16.

The maximum mortgage amount is given as £200,000 by one independent guidance source and £100,000 by another, and this conflict is not ruled on9. The official guidance is clear that the £100,000 limit applies to Pension Credit claimants and those who started claiming another qualifying benefit before January 20093.

CircumstanceMaximum mortgage interest covered
Most eligible claimants£200,0003
Pension Credit claimants£100,0003
Started another qualifying benefit before January 2009£100,0003

How to apply and how payments reach your lender

Support for Mortgage Interest is usually paid directly to your lender3. This means the money does not come to you and then go to the mortgage company; it goes straight to the lender to reduce the interest you owe.

The scheme has been in its current form since April 2018, when help with mortgage interest changed to a loan rather than a benefit17. If you are a homeowner and getting certain benefits, you could get help towards interest payments on your mortgage18. Homeowners on certain benefits may be able to get help towards mortgage interest payments called Support for Mortgage Interest17.

You may be able to get a Support for Mortgage Interest loan to help pay towards the interest on your mortgage repayments, and towards interest repayments on repairs or improvements you have made to your home19. If you claim Income Support, Pension Credit, income-related Employment and Support Allowance, or income-based Jobseeker's Allowance, you may be eligible20.

To apply, you will need to contact the Department for Work and Pensions. The loan is administered through the DWP, and payments are made directly to your lender3. If you are in Northern Ireland, the scheme is administered by the Northern Ireland Housing Executive, and there is separate guidance on repaying your mortgage interest on a low income3.

Paying the loan back: sale, transfer or death

You will need to pay this money back, with interest, when you sell or transfer ownership of your property21. The loan would need to be repaid with interest when you sell your home or transfer ownership22. You must pay the loan back when you sell your home or transfer it to someone else23.

You will be asked to repay the loan if you sell your home, if the title for your property is transferred, assigned or otherwise disposed of, or if you die24. SMI loans are repayable with interest when the property is sold, ownership is transferred, when the claimant dies, or on a voluntary basis4.

If you finish paying your mortgage, you will not need to repay your SMI loan unless you sell or transfer ownership of your home3. This means that if you pay off your mortgage but stay in your home, the SMI loan remains outstanding but does not need to be repaid at that point.

Interest continues to be charged at a daily rate if you stop receiving the loan or choose to stop it5. This means that even if you stop getting SMI, the interest on the loan you have already received will continue to build up until it is repaid.

When a claimant moves to a new property, they can transfer their SMI loan to the new property without repaying; the outstanding balance is transferred to the new property25. You may be able to move Support for Mortgage Interest to another property by contacting the DWP loan management team10.

Frequently asked questions

Does SMI cover the capital part of my repayment mortgage?

No. Support for Mortgage Interest only pays the interest on your mortgage. It generally cannot be used to pay off the amount you borrowed, which is the capital. That means even if you receive SMI, your mortgage balance will not go down, and you will still owe the original amount you borrowed. You may also get help towards interest on loans taken out for essential repairs or improvements, or to buy an ex-partner's share of your home after separation.

What interest rate is charged on an SMI loan?

A specific rate is not published here. What is clear is that the loan is repayable with interest, and interest continues to be charged at a daily rate if you stop receiving the loan or choose to stop it. The rate is set by the government and can change. Because the loan is secured on your property, the interest builds up until you sell, transfer ownership, or die.

Can I move my SMI loan to a new home?

Yes, in some cases. When you move to a new property, you can transfer your SMI loan to the new property without repaying it, and the outstanding balance is transferred. You will need to contact the DWP loan management team to arrange this. If you sell or transfer ownership without moving the loan, you will need to repay it as a lump sum with interest.

Can I get SMI if I am working or getting Statutory Sick Pay?

No. You cannot get Support for Mortgage Interest if you also receive Statutory Sick Pay, Statutory Maternity Pay, Statutory Paternity Pay, Statutory Adoption Pay, Statutory Shared Parental Pay, earnings from employment or self-employment, or a tax refund. SMI is only available to homeowners getting certain income-related benefits, so any earnings or statutory pay will usually stop it.

Can I make voluntary repayments on an SMI loan?

Yes. SMI loans are repayable with interest when the property is sold, ownership is transferred, or the claimant dies, but you can also repay on a voluntary basis at any time. Making voluntary repayments reduces the balance and the interest that builds up. If you finish paying your mortgage, you will not need to repay your SMI loan unless you sell or transfer ownership of your home.

Does SMI work the same way in Scotland and Northern Ireland?

Support for Mortgage Interest is a UK-wide scheme, but the guidance and support available differ. In Northern Ireland, SMI is administered by the Northern Ireland Housing Executive, and there is separate guidance on repaying your mortgage interest on a low income. In Scotland, help with mortgage interest is also available, but the advice and support routes differ. The core rules on eligibility, waiting periods and limits are broadly similar across the UK.

Does SMI stop if I go into hospital?

No specific rule for hospital stays is published here. What is clear is that if your benefits stop because you start full-time work or earn more, your SMI will also stop, but you may qualify for Mortgage Interest Run On payments for the next 4 weeks. If you stopped getting income-related ESA and applied for Universal Credit within a month, SMI restarts straight away.
