Disclosure of defined benefit plans [abstract]  
Retirement benefit schemes The Group’s subsidiary undertakings operate various funded and unfunded defined benefit schemes, including pension and post-
retirement healthcare schemes, and defined contribution schemes in various jurisdictions, with its most significant
arrangements being in the U.S., the UK, Canada, Germany, Switzerland and the Netherlands. Together, schemes in these
territories account for over 90% of the total underlying obligations of the Group’s defined benefit arrangements and over 60% of
the current service cost.  Benefits provided through defined contribution schemes are charged as an expense as payments fall
due. The liabilities arising in respect of defined benefit schemes are determined in accordance with the advice of independent,
professionally qualified actuaries, using the projected unit credit method. It is Group policy that all schemes are formally valued at
least every three years. The overall net asset for all pension and healthcare schemes in Group subsidiaries amounted to £72
million at 30 June 2025, compared to a net asset of £117 million at 31 December 2024 (30 June 2024: £88 million).
The Group continues to explore opportunities for risk management exercises in relation to retirement benefit arrangements and,
in May 2025, de-risked certain liabilities of its arrangements in the Netherlands through a buy-in contract fully funded by the
assets of the relevant scheme.
