Exhibit 99.1

28 November 2024

National Grid plc ('National Grid' or the 'Company')

Scrip Dividend for 2024/25 Interim Dividend

National Grid today announces the scrip dividend reference price for the 2024/25 interim dividend. A timetable is provided below.

For ordinary shareholders, the scrip dividend reference price for the 2024/25 interim dividend is 984.16 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 2024/25 interim dividend is US$61.9430. This is calculated by multiplying the scrip dividend reference price above by five (as there are five ordinary shares underlying each ADR) and by the average US$ rate for the equivalent dates.

The current terms and conditions of the scrip dividend scheme are available in the Investors section on the Company's website and from the Company's Registrar, Equiniti (0800 169 7775).

2024/25 interim dividend timetable:


7 November 2024	2024/25 half-year results and interim dividend amount declared - 15.840 pence per ordinary share; $1.0196 per ADR*
