Deposit Unlock

How does it work?

Buy your new home with just 5% deposit

Deposit Unlock is a new scheme developed by the Home Builders Federation and mortgage lenders meaning you can buy a new Sigma home with just a 5% deposit. This is an insurance-backed guarantee scheme meaning that you will have access to competitive mortgage rates, whether you are purchasing your first home, or looking to move home.

Who is it for?

Deposit Unlock can be used by both first-time buyers and home movers alike, and there is no upper limit on household income.

Which properties can the scheme be used on?

Deposit Unlock can be used on any of our new homes - houses and apartments, up to a value of £833,250*, subject to the lender's approval. There are no restrictions on location.

Benefits of deposit unlock

Deposit Unlock allows you to access competitive mortgage rates for purchasing a Sigma home with just a 5% deposit. The scheme is available now, there is no upper limit on household income, and it can be used by both first-time buyers and home movers. With Deposit Unlock, you own 100% of your new home.

How deposit unlock works

With a normal 95% mortgage, lenders carry higher risk and usually take out their own insurance against this. These additional costs are passed on to purchasers in the form of higher interest rates. With Deposit Unlock, those costs are met by the Home Builders Federation and its members, meaning you benefit from both a smaller deposit and competitive rates.

Deposit Unlock is currently available with participating bank lenders including Nationwide Building Society, Accord Mortgages and Newcastle Building Society. **
