Private Island Cost

Many of us working a standard nine-to-five job wonder and wish at the prospect of being incomprehensibly rich. To own a super flashy car, the finest clothes you could ask for, perhaps even your own private island.

An island in the Bahamas, off the US coast or even a Greek island would be absolutely dreamy. However, surely, when many people can’t afford to save for a home of their own, it would be unthinkable to own an entire island. Right?

Well, wonder not, as our experts at Slingo, one of the UK’s leading bingo sites, have analysed the prices of the private islands currently available for purchase. This allowed us to see where in the world it is the most affordable for you to buy a private island of your own. Additionally, we have looked at the average cost of a private island against the cost of a UK home, calculated per square metre.

The Average Cost of a Private Island vs the Cost of a UK House

Private Island Cost vs UK House Cost

The comparison between the cost of a private island against the cost of a UK home, per metre squared, is quite stark. The overall average cost of a UK home is currently around £278,108, which is far less than the average cost of a private island, of course, at more than £5.3 million.

However, when you calculate the average cost per metre squared, it begins to look quite different. On average, per metre squared, a private island would cost just £78. When you compare this to the cost of a house in the UK, it is 3,886% more expensive to buy a home in the UK, when calculated per square metre. According to figures as of April 2023, it would cost an average of £3,090, per square metre, to buy a 90 square metre home in the UK. 

While many of these private islands have electricity and water, not all have those by default, they’re mostly undeveloped land masses without any buildings you might reside in. Whereas, a home in the UK, is guaranteed to have electric, water, plumbing and many other features, which reflects their higher value to an extent, there is also a higher demand for homes, another contributing factor. 


To begin, we started by taking down the acre, price, region and name of each available private island on Private Islands Online. This was completed on (27/06/2023). We only included private islands with listed prices.

We then calculated the average price of each island (in GBP, which was converted from USD using Google Finance on 28/06/2023 at 11:20 am BST). We then calculated the average size of the islands as metres squared. This allowed us to find out which regions with at least two available private islands had the least and most affordable private island prices. For this section, we did not include regions with fewer than two private islands.

We then used the UK House Price Index: data downloads April 2023, to get the average price of a house in the UK. And then an ONS resource: House prices: how much does one square metre cost in your area? to get the average UK house size in metres squared (90). This allowed us to calculate both the average cost of a private island and a UK house per metre squared, and then calculate the price difference between the two.
