How does it work?

Lenders typically don’t offer 95% mortgages on new-builds, as they are viewed as more risky. This scheme allows you to buy one with just a 5% deposit. That’s because the housebuilder reduces the lender’s risk by insuring the mortgage.

Deposit Unlock is a relatively new scheme, and is only available through a few lenders. Plus, it can only be used with participating housebuilders and on eligible developments or properties.

Things to consider

All mortgages have risks and benefits. Here are some key factors you should know before applying for the Deposit Unlock scheme.


What are the benefits?

Buy a new build with a small upfront deposit

Lenders typically require a 15%-25% deposit on new-build properties. With Deposit Unlock, you could buy a new build home with just a 5% deposit, meaning that you might be able to buy sooner, or buy a more expensive property.

Access to a wide range of house builders

There are 31 house builders offering the Deposit Unlock scheme - so you’ll have a range of choices when looking for a suitable home. However, not every house they build will be eligible for the scheme.

Buy a brand new home

There are many benefits of buying a new-build. You’ll typically have warranty on all white goods, and you can make significant savings due to excellent energy efficiency.

Risks and considerations

Limited choice of mortgage lenders

There are only three lenders that currently support the Deposit Unlock scheme. This means you’ll have limited choice when choosing a suitable mortgage, and you might not have access to the best interest rates.

The mortgage amount is capped at £750,000

You cannot buy a home that requires a mortgage larger than £750,000, which might be limiting in areas like London or the South West.

Be wary of the new build premium

As the property is no longer ‘brand new’ once you’re in it, the value of a new build can initially fall. If you don’t plan to live in the home for a long time, this means you might end up selling the home for less than you bought it for.
