The board of directors of United Utilities Group PLC (the board) is provided with information on a single segment basis for the purposes of assessing performance and allocating resources. The board reviews revenue, underlying operating profit (see Our performance), operating profit, assets and liabilities, regulatory capital expenditure and regulatory capital value (RCV) gearing at a consolidated level. In light of this, the group has a single segment for financial reporting purposes and therefore no further detailed segmental information is provided in this note.
The group's revenue predominantly arises from the provision of services within the United Kingdom, with less than one per cent of external revenue and non-current assets being overseas.
The group has a large and diverse customer base and there is no significant reliance on any single customer.
