You can use the equity released through remortgaging for a variety of purposes.
Common uses include funding home improvements, such as an extension or renovation, paying off high-interest debts, or helping family members with expenses like a deposit for their own property.
Some also use it for larger purchases or investments, such as buying a car or funding a business.
Keep in mind that how you intend to use the equity can impact your mortgage application, as some lenders may have restrictions.
