Homeowners on Pension Credit can get help with two quite different kinds of housing cost. One is a loan that the family will eventually repay. The other is simply part of the benefit.
Support for Mortgage Interest is a loan
Help with mortgage interest stopped being a benefit in April 2018. The regulations now provide for the Secretary of State to make loan payments to claimants of state pension credit and other benefits, in respect of owner-occupier payments, principally mortgage interest (Loans for Mortgage Interest Regulations 2017, checked 14 September 2026).
The distinction matters for the family as much as for the claimant. A loan accumulates, and it is repaid out of the home. It can still be the right choice for somebody who would otherwise struggle with the mortgage, but it should be understood before accepting it.
No waiting period on Pension Credit
Pension-age claimants are treated more generously than working-age ones on timing. GOV.UK says that if you get Pension Credit, payments can start from the date you start getting Pension Credit (GOV.UK, Support for Mortgage Interest (SMI), checked 1 November 2026). There is no qualifying period to sit through first.
That makes Pension Credit itself the gateway. Somebody who has not claimed it because they assume their home rules them out should check, because owning a home does not count against Pension Credit, and the claim can bring mortgage help with it. Our Pension Credit guide covers eligibility.
How much it covers
The loan pays towards the interest, not the capital, and the capital it is worked out on is capped. The regulations set the capital limit at £100,000 in most cases (Loans for Mortgage Interest Regulations 2017, regulation 11, checked 1 November 2026). GOV.UK confirms the £100,000 limit for people getting Pension Credit.
The rate used is not your lender’s rate. The regulations tie it to the average mortgage rate published by the Bank of England, varied when that average moves by 0.5 percentage points or more (regulation 13, checked 1 November 2026). GOV.UK’s page gives the rate in use at any time. The payment usually goes straight to the lender.
Repaying it
The loan is secured on the home: in England and Wales by a legal mortgage from each legal owner if all are in the benefit unit, otherwise an equitable charge, and in Scotland a standard security (regulation 5, checked 1 November 2026). It sits behind the main mortgage, and interest is charged on the balance until it is repaid.
It falls due on specific events. The outstanding amount becomes immediately due and payable where the home is sold, or on the death of a claimant who has no partner (regulation 16, checked 1 November 2026). For a couple, that usually means when the survivor dies, so it becomes a debt the executors settle from the estate.
Applying, and when payments stop or go missing
The application runs through your lender. GOV.UK says that when you claim a qualifying benefit you are asked about housing costs, and to apply you fill in and sign a form, then send it to your lender, which completes it and sends it to the office that pays your benefit (GOV.UK, Support for Mortgage Interest (SMI): how to apply, checked 1 November 2026).
If you qualify, you are offered the loan and can accept or decline it. GOV.UK says that if you turn it down at first you can still accept later while you are eligible, and payments to your lender can be backdated to when you were first entitled. There is no fee to apply and no credit check (GOV.UK, Support for Mortgage Interest (SMI): eligibility, checked 1 November 2026).
Payments normally go straight to the lender, which is why a gap shows up on the mortgage statement first. If the lender says nothing has arrived, contact the office that pays your benefit, the Pension Service for Pension Credit, and check that the benefit itself has not stopped, because the loan depends on it. GOV.UK says SMI restarts straight away if you stopped getting Pension Credit and were moved to Universal Credit; otherwise the normal waiting rules apply again.
When the owner dies, the loan does not always have to be repaid at once. GOV.UK says a partner you lived with will usually be able to inherit the loan with the home, while anyone else who inherits it must repay immediately, and that if the home is sold some of the loan may be written off (GOV.UK, Support for Mortgage Interest (SMI): repaying your loan, checked 1 November 2026).
Ground rent and service charges are not a loan
Leaseholders get a different kind of help, and it is easy to miss. Ground rent on a long tenancy and service charges are met as housing costs under Pension Credit (State Pension Credit Regulations 2002, Schedule II, paragraph 13, checked 1 November 2026). They are added to the award, not lent.
GOV.UK lists them among the housing costs you could get an extra amount for, naming ground rent if your property is leasehold and some service charges (GOV.UK, Pension Credit: what you'll get, checked 1 November 2026). That is significant in retirement developments, where service charges can run to thousands of pounds a year.
Which service charges count
Not every line on a service charge bill is eligible. The same paragraph excludes amounts for fuel, and service charges that are ineligible under the Housing Benefit rules it cross-refers to, along with amounts for repairs and improvements (Schedule II, paragraph 13, checked 1 November 2026).
In practice, send the Pension Service the full service charge demand with its breakdown and let it decide what qualifies, rather than guessing. Charges for communal cleaning, lighting and maintenance of shared areas are the kind families should ask about; heating and personal care are the kind that are excluded.
Both forms of help come through the Pension Credit claim. If you already get Pension Credit and have never been asked about your mortgage or service charge, tell the Pension Service, because housing costs are not added automatically.
