LONDON, April 27, 2026, 19:06 BST
- National Grid closed Monday in London down 0.11% at 1,293.60p, with trading volume hitting 6.20 million shares, according to LSEG data.
- Questions about the company’s position in the grid are swirling as the UK pushes to fast-track renewables, overhaul gas-tied power pricing, and quicken network improvements.
- National Grid is up next on May 14, set to deliver its full-year numbers. The company has already warned investors to brace for a hit—about 1p shaved off underlying earnings per share, which excludes certain one-offs.
Shares of National Grid plc slipped on Monday, taking a breather after a recent climb. Investors looked hard at the UK network operator, balancing its potential role in Britain’s fresh clean- energy drive with ongoing worries about policy shifts, interest rates, and expenses tied to the U.S.
The shift comes into sharper focus with the government’s new energy package, which pulls grids and storage further into the core investment narrative. London is looking to loosen the connection between electricity bills and gas prices, pitch fixed-rate contracts to established low-carbon producers, and push ahead with grid enhancements to carry more renewable power nationwide.
Last week’s written ministerial statement flagged the potential for public land to deliver as much as 10 gigawatts of renewable energy—roughly enough for 5 million homes. The announcement highlighted upcoming reforms on land access rules, network approval, and self-build grid connections. Renewables, of course, still need more grid infrastructure. That’s where National Grid steps in.
National Grid ended the session at 1,293.60p, slipping 1.40p. Still, the stock has climbed 1.35% in the past five days and 20.67% over one year, market data from Investors Chronicle show. The shares have tracked moves in other UK utilities, as investors juggle defensive earnings, big capex outlays, and political uncertainty.
Morningstar flagged National Grid, SSE, and Centrica on Monday as stocks caught up in the UK’s push toward renewables—each with its own angle. SSE sits closest to the action, focused heavily on wind, hydro, and solar projects. Centrica leans more on gas, supply contracts, and has a stake in nuclear. National Grid stands apart; its business is network infrastructure, so its returns hinge on regulated assets, not just electricity production.
David Harrison, who manages funds and oversees sustainability at Rathbones Asset Management, described National Grid as being well-placed for long-term capex commitments, he told Morningstar. Still, Morningstar’s energy analyst Tancrede Fulop cautioned that the investment case isn’t “a simple one-way trade” due to inflation and the impact of higher borrowing costs on capital-intensive assets.

National Grid doesn’t look like a typical generator, thanks to its regulated setup. As Reuters notes, the UK energy firm handles electricity transmission and distribution across Great Britain, with electricity and gas networks stretching into New England and New York.
The UK regulatory landscape is changing, too. Under Ofgem’s RIIO-3 regime—“Revenues = Incentives + Innovation + Outputs”—revenue and incentive levels for monopoly gas and electricity networks are locked in from April 2026 through March 2031. National Grid’s UK electricity transmission business falls within that five-year price control. Ofgem
Back in March, National Grid projected adjusted earnings per share would rise by 13% to 15% in 2027, pointing to increased allowed revenue with the fresh regulatory cycle. That outlook has put the stock in focus as investors eye bigger grid investments.
But there’s a fresh expense cloud in the numbers. In its April 13 filing, National Grid reported full-year results tracking expectations, yet flagged an estimated net impact of around 1p per share on underlying EPS. The culprit: customer refund charges from the March 19 U.S. Federal Energy Regulatory Commission decision on New England Transmission, and U.S. storm costs running higher than forecast. Lower finance costs helped cushion the blow a bit.
The risk hasn’t disappeared. UBS stuck with its Sell call on National Grid as of April 24, holding a 1,160p price target, according to MarketScreener — that’s still under where shares finished on Monday. Meanwhile, Rain Newton-Smith, who heads the CBI business group, flagged to Reuters that “clarity and confidence are paramount” in periods of wild energy-market swings, pointing out that sudden policy changes can hit investors from either direction.

Pushing into direct market intervention can backfire, Pulse Clean Energy chief executive Trevor Wills told New Energy World, warning of “unintended outcomes.” That’s the sticking point for National Grid and similar operators: the demand for new wires is clear, yet profits hinge on regulation, planning timelines, financing conditions, and the appetite among voters to shoulder the costs of the energy transition.

The calendar’s empty for now. National Grid’s results on May 14 will reveal if the company’s growth narrative holds up as it juggles rising U.S. expenses and ramps up network investment. The stock isn’t just a defensive utility play anymore—it’s become a gauge for whether Britain’s clean-energy ambitions can convert grid constraints into steady, regulated profits.
