The market for data centres across Europe is growing. In fact, in the UK, Germany and the Netherlands, capacity is increasing faster than ever. While London and the Inner M25 area is the largest area of data centre space, with 260,000 square metres, followed by Slough at 107,000 square metres, other clusters include Cardiff, Manchester, Woking, and Farnborough. New data centre space is also emerging in Edinburgh, Leeds, and Newcastle. Portsmouth and Gloucester have opened data centre facilities within the last year. A paper by techUK argues that data centres underpin the digital economy, improving productivity and generating employment across multiple business centres.
