Mortgage payment holidays are in place for people who are struggling with their repayments. You can apply for one if you've kept up-to-date with your payments. You don't need to provide proof of how your finances have been affected by COVID-19.
There are other ways your lender may be able to help you, such as allowing you to reduce payments.
You can request payment breaks even if coronavirus hasn't affected you. Find out more about dealing with mortgage arrears.
