Scrip Dividend for 2018/19 Interim Dividend

The optional scrip dividend, allowing shareholders to receive new fully paid ordinary shares in the Company, instead of a cash dividend, is available to ordinary shareholders on the register on 23 November 2018, the dividend record date. A timetable is provided below.

For ordinary shareholders, the scrip dividend reference price for the 2018/19 interim dividend is 829.86 pence. This is calculated as the average closing mid-market price of an ordinary share for the five dealing days commencing with, and including, the ordinary share ex-dividend date.

For American Depositary Receipt (ADR) holders, the scrip ADR reference price for the 2018/19 interim dividend is US$53.1484*. This is calculated by multiplying the scrip dividend reference price above by five (as there are five ordinary shares underlying each ADR) and by the average US$ rate for the equivalent dates.

The current terms and conditions of the scrip dividend scheme are available on the Company's website at www.nationalgrid.comin the Investors section, from Link Asset Services (0371 402 3344, [e-mail]) and are also set out in full in the announcement released by the Company on 7 June 2018, which is available on the National Storage Mechanism.
