Support for Mortgage Interest in Northern Ireland

The short answerIf you own your home and get Universal Credit, Pension Credit or income-related ESA, Support for Mortgage Interest pays towards the interest on your mortgage, straight to your lender. It covers interest on up to £200,000. It is a loan, repaid from what is left when the home is sold or changes hands.

It is not free money, and it does not pay off what you borrowed. But it can keep a home safe through a hard spell, with no credit check and no fees.

What it is

The Department for Communities makes regular payments towards the interest on your mortgage, usually straight to your lender. There is no lump sum, no credit check and no set-up fee.

It does not pay off what you borrowed, insurance, or arrears. The amount you owe grows with each payment.

Who can get it, and when

You must own your home and get Universal Credit, Pension Credit or income-related ESA. The help can start:

How much it covers

It covers the interest on up to £200,000 of your loan or mortgage. For people on Pension Credit the limit is lower, £100,000. If you already get it and move to Pension Credit within 12 weeks of your other benefits stopping, the £200,000 limit stays.

Paying it back

The loan is usually secured on your home. When you sell or ownership passes, you pay the Department back from any equity left after your mortgage is repaid.

Common questions

Is Support for Mortgage Interest a loan?

Yes. You repay it from the equity in your home when it is sold or passes to someone else.

How much mortgage does SMI cover?

The interest on up to £200,000, or £100,000 for most people on Pension Credit.

How long do I wait for SMI on Universal Credit?

Three consecutive months on Universal Credit.

No. It only helps with the interest.
