The most common uses are home improvements, helping a family member with a deposit for their own home, paying off higher-rate unsecured debt, funding major life events, or building up savings. Lenders do not restrict what you do with the money, though they may ask about the purpose during the application.
Home improvements are popular because they can add value to the same property you are borrowing against. A well-planned kitchen, loft conversion, or extension can push the value up further. Our remortgage for home improvements page covers this in more detail.
If consolidating debts is your goal, it is worth understanding that you are turning unsecured debt into secured debt. This typically gives you a lower interest rate and a single payment, but the debt is now tied to your home. If you fall behind on mortgage payments, your home is at risk. We make sure you understand this fully before we recommend any consolidation remortgage.
