What is Deposit Unlock?

Deposit Unlock allows you to buy a new-build home from participating home builders with just a 5% deposit.

It’s been developed by the Home Builders Federation, with lenders and the house building industry.

Why choose Nationwide?

Helping each other to buy homes of our own was one of Nationwide’s founding principles.

This is why we’re proud to participate in Deposit Unlock, to make buying a new-build home more affordable.

With a Nationwide mortgage and using Deposit Unlock, you could:

  • Buy a new-build home with at least a 5% deposit

  • Borrow between 90.01% and 95% of the property (Loan to Value)

  • Borrow up to £750,000

  • Borrow for up to 40 years. Remember, a longer-term mortgage means you'll be paying more in interest over the length of your chosen period.

To be eligible for Deposit Unlock you need to:

  • be a first-time buyer or moving home
  • have at least a 5% deposit
  • buy an eligible new-build home, not a pre-owned property
  • buy the property from a builder using Deposit Unlock.

To apply for a Nationwide mortgage using Deposit Unlock you, or anyone you’re applying with, cannot also use an affordable home ownership scheme. For example, shared ownership.

Other ways we can help you buy a home

If Deposit Unlock isn’t right for you, there are other ways we could help you buy your first home or move house.

These include the Helping Hand mortgage, 95% mortgages and affordable home ownership schemes.
