Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	Basis of Presentation and Responsibility for interim Financial Statements We prepared the accompanying unaudited condensed consolidated financial statements of Luxfer Holdings PLC and all wholly-owned, majority owned or otherwise controlled subsidiaries on the same basis as our annual audited financial statements. We condensed or omitted certain information and footnote disclosures normally included in our annual audited financial statements, which we prepared in accordance with U.S. Generally Accepted Accounting Principles (GAAP). Our quarterly financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2022. As used in this report, the terms "we," "us," "our," "Luxfer" and "the Company" mean Luxfer Holdings PLC and its subsidiaries, unless the context indicates another meaning. In the opinion of management, our financial statements reflect all adjustments, which are only of a normal recurring nature, necessary for the fair statement of financial statements for interim periods in accordance with U.S. GAAP and with the instructions to Form 10-Q in Article 10 of Securities and Exchange Commission (SEC) Regulation S-X. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of our financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates, and any such differences may be material to our financial statements.
Fiscal year	Our fiscal year ends on December 31. We report our interim quarterly periods on a 13-week quarter basis, ending on a Sunday. The Second Quarter 2023, ended on July 2, 2023, and the Second Quarter 2022, ended on June 26, 2022.
Accounting standards issued but not yet effective	Accounting standards issued but not yet effective None that will be material to the Company.
