National Grid plc Stock (NG.L): Share Price, RIIO‑T3 Decision, Sea Link Contracts and Analyst Forecasts as of 20 December 2025
National Grid plc stock is heading into the end of 2025 with investors focused on a single, very modern problem: electrification is accelerating faster than grid infrastructure can comfortably keep up. For a regulated utility, that can be a gift (predictable, funded growth) or a headache (political scrutiny, bill impacts, execution risk). Right now, the market is weighing both. As of the latest available close (19 December 2025), National Grid shares (LSE: NG.) were trading around 1,142p, giving the group a market capitalisation of roughly £56.6 billion and a trailing dividend yield around 4.1% (based on broker-screen pricing).
