Today, more tall buildings are being planned and constructed than ever before, with 436 towers – defined as those with more than 20 floors – proposed, in planning, approved, or under construction in London, according to research by New London Architecture1. As the number of tall buildings under construction in the UK increases, greater focus needs to be placed on mitigating the associated risks, which can lead to project delays and significant reinstatement costs. While recent developments, such as the recent UK vote to leave the European Union, could impact planned projects moving forward, we expect to see this trend continue over the long-term. This paper has been designed to highlight and bring greater awareness to the various risks and insurance challenges associated with tall tower construction in the UK. Sky-high Risk: The Impact of Increasing Tall Buildings in the UK 3 MARSH REPORT July 2016 FIGURE 1 London’s tallest buildings, completed and planned Source: Skyscraper Center The graphic below (FIGURE 1) shows a selection of the tallest completed, under construction, and proposed buildings in London. Out of these buildings, 13 are proposed or under construction demonstrating how London’s skyline is set to be transformed over the next decade and the growing trend towards tall tower construction. The height of London’s skyline remained largely unchanged during the 1980s and 1990s, with only Tower 42, One Canada Square, and the Panoramic being completed at a height of more than 20 floors. In contrast, since 2000, 50 buildings with more than 20 floors have been built in London, with a further 25 under construction and due for completion over the next three years. The Shard is currently London’s tallest building standing at around 306 metres, followed by One Canada Square and 110 Bishopsgate. 22 Bishopsgate, which is currently under construction, will surpass all but the Shard when completed.

However, new construction opportunities available to build higher than ever puts greater focus on the need to mitigate the associated risks as the UK plans its high-rise revolution.* * Note: Listed data for proposed or under construction buildings is based on information currently available.

This year’s pipeline has seen an increase of 119 tall buildings compared to 2014, bringing the current number of those proposed, approved, and under construction to 436, according to New London Architecture (see FIGURE 3). 6 Marsh MARSH REPORT July 2016 FIGURE 3 Comparison of London tall buildings pipeline 2014-2016 It is not just Source: New London Architecture the number of 500 these projects 400 that needs to be taken into 300 consideration, 200 but also the 100 fact that the height of the 0 2014 2015 2016 individual Proposed (pre- and post-formal submission) Refused (since last review) buildings Approved seems to be Under construction Completed Status unknown rising.
