The research is based on a survey of more than 120 Data Centre providers in the UK market, with 250 facilities. TCL has also created a forecast breakdown of the key UK Data Centre customer segments - from a sample of 25 UK Data Centre providers.

TCL has used its database to calculate the UK Data Centre market size by space (m2) and by total customer power (MW) – referred to as DCCP (Data Centre Customer Power). TCL has broken down the total overall space and power by the main regional Data Centre clusters around the UK (including London, outside the M25 ring-road area and selected cities such as Manchester).
