The possible offer was announced on the London Stock Exchange.
Marsh must announce either a firm intention to make an offer, or that it does not intend to make an offer on Jelf, by 5.00pm on 16 September 2015.
The statement published on the London Stock Exchange this morning said: "The Board of Jelf notes the recent press speculation and confirms that it is in discussions with Marsh Ltd ("Marsh") in relation to a possible cash offer by Marsh for the entire issued and to be issued ordinary share capital of Jelf.
