Buyers may have been benefiting from falling average deposits nationally, but that is not the case for London transactions where purchasers are paying almost three times more to get on the property ladder, research shows.

Data from conveyancers My Home Move has found that while the average deposit size nationally last year fell from 26.29% to 25.77%, in London this has actually gone up from 25.55% to 26.35%.

The research looked at 60,000 transactions that My Home Move worked on and compares them against Land Registry data.

The average property price in 2015 was £182,293 while the average deposit was 25.77%, or £46,986.

In comparison, in the capital the average property price in 2015 was £482,512 and with an average 26.35% deposit, buyers were paying £127,141.

This works out at 2.7 times more than the amount buyers put down nationally.

Doug Crawford, chief executive of My Home Move, said: “The London property market has always commanded greater prices than anywhere else in the UK, but our research has shown just how extreme the situation is becoming.

“London property prices have risen by 27% in the last three years and while the rest of the UK has seen a small decrease in the average deposit size, those looking for a London home are depositing 170% more than their UK counterparts.

“This situation is unsustainable and has been driven by rising house prices. For some, their deposit will come from the equity in the property they are selling. However, for many, they will still need to save tens of thousands of pounds to make the move on to and up the property ladder.”
