Use a Deposit Boost to build a deposit from a loved one's home

Add to your savings or create a house deposit from scratch with help from a loved one. They’ll unlock money from their property to gift to you as a deposit.

How does it work?

A Deposit Boost involves two separate mortgages. The first is taken out by a loved one against their own property in order to unlock some money. This can be done using an interest- only retirement mortgage, so monthly payments are kept low, or through a standard remortgage.

The proceeds are given to you as a gifted deposit, and we’ll arrange your mortgage. With a larger deposit you could increase your budget, and also access lower interest rates. On average our Deposit Boost customers will save £17,000 in interest alone over a 5-year period.

Things to consider

All mortgages have risks and benefits. Here are some key things you should know before applying for a Deposit Boost


What are the benefits?

Buy a home of your own sooner

On average, it takes almost 10 years to save up for a house fund. With a loved one helping to top up your deposit, you can get on the property ladder quicker.

Access lower interest rates

With a larger house deposit, lenders will typically offer you lower interest rates as you present less of a risk to them. This means over the course of your mortgage, you could pay significantly less in interest to your lender.

Your Booster can support without using cash

As the gifted deposit is unlocked from your Booster’s property, they don’t need to use cash savings, or draw down on pensions or investments.

Your Booster isn't a guarantor

As the two mortgages are separate, there’s no link between you and your Booster financially. They are responsible for their mortgage, and you yours. If either of you missed repayments, the other party is not liable.

Your Booster may reduce their IHT liability

Because your Booster is releasing money from their estate to gift to you earlier in your life, your Booster’s future inheritance tax liability could be reduced.

Risks and considerations

Debt against the Booster's home

As with any mortgage, there is a risk of repossession if the Booster’s monthly repayments are missed. We carefully assess affordability to mitigate this risk.

Your Booster must own at least 50% of their home

Boosters with an existing mortgage have fewer choices available to them, particularly if they are close to retirement. As a minimum, they will need to have paid off at least 50% of their mortgage.

Your Booster will need to prove affordability

As the Deposit Boost is a mortgage product, Boosters will need to pass a credit check and prove affordability. If they are overcommitted with existing borrowing and outgoings, or their income isn't sufficient, they may not be eligible.

Your Booster will have no legal rights to the property

As a Deposit Boost involves two separate mortgages, your Booster will not be a co-owner of the property. If your loved ones are interested in contributing to your house deposit in return for equity in the home, explore Deposit Loan instead.
