Paying for Your Annexe

An annexe is a significant cost, but there are several practical ways to fund it. Here are the options our customers typically use.

Ways to Fund Your Annexe

Every family's situation is different. These are the most common approaches.

Savings & Cash

Many families fund their annexe from savings, often combining resources from multiple family members. This avoids interest costs and keeps things simple.

  • No interest payments
  • Straightforward process
  • Often combined family contributions

Equity Release

If your parent is selling their home to move into the annexe, the sale proceeds can fund the build with plenty left over for retirement.

  • Average UK home sale: £280,000+
  • Covers annexe cost with surplus
  • Extra funds for care or enjoyment

Remortgage

If you have equity in your home, remortgaging can release funds for the annexe. The annexe then adds value back to your property.

  • Access home equity at low rates
  • Annexe adds 15-30% property value
  • Spread cost over mortgage term

Family Contributions

Many families share the cost between generations. The whole family benefits, so the whole family contributes.

  • Parents contribute from savings
  • Siblings share the cost
  • Fair reflection of shared benefit
