There is no single data source that comprehensively measures all business start-ups within the UK. However, ONS has published statistics showing that there were 2,770 businesses newly registered for VAT or PAYE in the Wealden constituency between 2010 and 2014. Some newly registered businesses will have been trading for a number of years and other active businesses will not be covered because they are operating below the VAT and PAYE registration thresholds.
