• Expenditure in other first tier third party suppliers. Across the Preese Hall site, Cuadrilla has a large number of suppliers, approaching 100, for the provision of both equipment and services. These supplier contracts involve a wide range of functions and include the preparation of the initial site, site security, waste removal, sample analysis etc. Some of Cuadrilla’s suppliers spend a substantive amount of time on site and will account for a large proportion of staff on site at any point in time. Other suppliers will rarely or indeed never visit the site.
