- Ernst & Young LLP
- Audit opinion
- Unqualified (clean)
- Going concern
- Affirmed
“The Company utilises treasury facilities provided to it by financing entities, which are subsidiaries of Solvay S.A.. As the Company is reliant on these group funding arrangements, a letter of support from Solvay S.A. has been obtained, confirming they will provide this support for a period to 31 December 2026. In satisfying themselves that Solvay S.A. has the means and ability to provide such financial support if required, the directors have held discussions with group directors, have understood the available facilities and cash reserves of the parent undertaking, have reviewed group cash flow forecasts, including sensitivities and challenged the assumptions within and are satisfied there is sufficient available headroom on available facilities including covenant requirements. Thus, with the letter of support in place, the directors continue to adopt the going concern basis of accounting in preparing the annual financial statements for a period to 31 December 2026.”
Significant events
- “Solvay Interox stopped the Hydrogen Peroxides production at Warrington site at the end of March 2024.”
- “As at 31 December 2024, the Company recognised restructuring provisions of £7.2m related to the cessation of the hydrogen peroxide production.”
- “There have been no significant events affecting the Company since the year end.”

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
