Going concern

Affirmed

“The directors have considered the Company's principal risks and uncertainties and concluded that the Company will have sufficient funds available under its current resources and committed facilities to continue to meet its liabilities as they fall due for at least 12 months from the date these financial statements are approved. These financial statements have been prepared on the going concern basis, which the directors believe to be appropriate for the following reasons: • The Company is part of the E.ON SE group, one of Europe's largest energy groups, and performs key business activities including the supply of energy efficiency measures to residential and municipal customers. • The Company is a member of the UK cash pooling facility managed by E.ON SE, whereby the cash balance of the Company is swept into an inter-company bank account on a daily basis. To the extent that working capital requirements arise, these are met through access to the cash pooling facility. As at the date of approval of these financial statements, the Company had a net receivable balance from that facility. • The Company's parent, E.ON UK plc, has significant receivables from its immediate parent company, E.ON UK Holding Company Limited ("HoldCo"). HoldCo has prepared a base case financial forecast covering the E.ON UK group companies ("the UK Group"), including the Company, for at least 12 months from the date these financial statements are approved. These forecasts indicate that the UK Group will have sufficient funds available under its current resources and committed facilities to continue to meet its liabilities as they fall due. • HoldCo has also prepared a range of potential scenarios. This includes certain severe but plausible downside scenarios under which the UK Group requires the extension of committed facilities from the ultimate holding company, E.ON SE, to meet its working capital requirements. The directors consider that in these circumstances, E.ON SE would have the ability and intention to provide funding such that the UK Group will continue to meet its liabilities as they fall due E.ON SE has indicated its intention to continue to make available such funds as are needed by the UK Group and intends to renew the internal credit facilities as required during the going concern assessment period. As with any company placing reliance on other group entities for financial support, the directors acknowledge that there can be no certainty that this support will continue although, at the date of approval of these financial statements, they have no reason to believe that it will not do so. Consequently, the directors are confident that the Company will have sufficient funds to continue to meet its liabilities as they fall due for at least 12 months from the date of approval of these financial statements and therefore have prepared these financial statements on a going concern basis.”

Each % is (latest − prior) ÷ |prior| for the line item as filed. The comparison is only shown when the latest and prior accounts cover broadly equal-length periods — short or long stubs (typical around incorporation or a year-end change) are suppressed rather than misrepresented. Lines a company doesn't report are omitted. About these numbers
