Two billionaire brothers have bought the London Heliport in Battersea for an estimated £25m.

David and Simon Reuben purchased Battersea's heliport, the only licensed commercial helipad in the capital, from Andrew Davis, former chief executive of the Von Essen hotels group which has collapsed into administration.

The sale was helped because the heliport has an exemption from the no-fly zone during the Olympics "meaning a large number of dignitaries and other VIPs will be able to use it as an easy access route to the 2012 Games", the Reuben Brothers said in a statement.

However, residents should not have to worry about increased helicopter noise as the Civil Aviation Authority (CAA) has powers to limit the number of flights per day.

A London Assembly report from last year confirmed the capital is limited to 12,000 commercial helicopter flights per year or 1,000 per month, which on average is about 30 per day.

Mr Davis bought the heliport, which opened in 1959 through the separate Von Essen Aviation company for £50m in 2007.

The Reuben brothers, who amassed a £6bn fortune through property and internet interests, already own Oxford Airport and fought off bidders including Joe Bamford, owner of the digger manufacturing giant JCB, and Mohammed Al Fayed, former owner of Harrods.
