(a)The remuneration payable to KPMG, the Group auditors, is approved by the Audit and Risk Committee. The Committee sets the policy for the award of non-audit work to the auditors and

approves the nature and extent of such work, and the amount of the related fees, to ensure that independence is maintained. The fees disclosed above consolidate all payments, including

overruns, made to member firms of KPMG by the companies and their subsidiaries, along with fees in respect of joint operations paid for by the Group. Non-audit services arise largely from

assurance and regulation related work.

(b)Other assurance services relates to the review of non-statutory financial information including sustainability reporting.
