The keys are expected to land somewhere in the UK and will contribute to the purchase of a home, with the average property in the UK currently worth £276,091, according to the Halifax HPI.

In the UK, 55% of all homes are owned by people aged 55-plus, and 47% find it impossible to save for a deposit on their own, with the majority (27%) taking between five and 10 years to save.

Nima Ghasri, director at Good Move, said: “We know that the property market is especially volatile right now, and many Brits struggle to get their foot on the property ladder and buy their dream home.

“We really wanted to help anyone in this situation in this campaign in a fun and exciting way – so if you can find our keys after they’ve landed from space then we’ll supply £10,000 towards a deposit.

“We really hope this money can brighten up someone’s January and can’t wait to see our keys’ journey into space!”
