London, June 10, 2026, 14:10 (BST)
- National Grid traded around 1,195p in afternoon London dealing, down 0.38%, as investors weighed funding costs behind its major grid expansion plan.
- A June 9 SEC filing showed the company issued $750 million of 5.405% notes due 2036.
- Fresh UK grid-connection reforms support the growth story, but analysts are watching valuation, debt and political risk.
National Grid plc shares edged lower on Wednesday as a fresh U.S. debt filing pulled attention back to the central question for investors: how the utility funds one of the biggest grid spending programmes in Europe without letting borrowing costs eat into returns. The London-listed stock was quoted at 1,195p at 14:02 BST, down 0.38% on the day, after opening at 1,198p and touching an intraday high of 1,201p.
The immediate change from yesterday is on the financing side. In a June 9 Form 6-K, National Grid said it had issued $750 million of 5.405% notes due 2036 and filed the underwriting agreement and supplemental indenture tied to the deal. Notes are bonds: investors lend the company money and receive interest until the debt matures.
The prospectus says the notes are “senior unsecured” obligations, meaning they rank ahead of lower-priority debt but are not backed by specific pledged assets. The filing also showed expected proceeds before expenses of $747 million, with delivery to purchasers on or about June 9. SEC
That matters because National Grid is no longer being valued only as a slow-moving dividend utility. In its May full-year results, the company said it plans at least £70 billion of cumulative capital investment from 2026/27 to 2030/31, targeting asset growth of around 10% and underlying earnings-per-share growth of 8% to 10% from a 78p baseline. Chief Executive Zoë Yujnovich called it the “largest investment programme in our history.” National Grid
The growth case is real. National Grid reported record capital investment of £11.6 billion for the year to March 31, 2026, up 18% at actual exchange rates, while underlying EPS rose to 78p. But the same results also showed net debt at £44.2 billion, up £2.8 billion from the prior year, largely because of higher capital spending.
Wednesday’s UK energy news gave bulls something to point to. Britain’s National Energy System Operator said offers had been made to 713 of 1,223 projects in the 2030 grid-connection pipeline, covering 37 gigawatts of offshore wind, onshore wind, solar, battery storage, gas and hydro projects. Reuters reported that the offers set out when and where projects can connect and what network upgrades are needed.
The link to National Grid is indirect but important. NESO runs and plans the system; National Grid owns and operates major electricity transmission infrastructure in England and Wales, according to AJ Bell’s company profile. More connections mean more need for wires, substations and cables, the assets that drive regulated returns for a network owner.
Still, the market reaction was muted because connection reform also highlights the scale of delivery risk. Reuters said the process could help unlock up to £40 billion of annual clean-energy investment, but it also noted that thousands of kilometres of new electricity lines and cables are required. That is the opportunity and the headache in the same sentence.
Analysts have become more cautious on that trade-off. Deutsche Bank Research cut National Grid to “hold” from “buy” on Monday and lowered its price target to 1,250p from 1,370p, according to Morningstar’s Alliance News feed. Morningstar Investing.com reported that Deutsche analyst James Brand cited valuation and policy uncertainty, saying the stock trades at a “significant premium” after adjusting for extra “fast money” allowances.

The caution was not limited to National Grid. Deutsche also cut target prices for SSE, Severn Trent and United Utilities, while keeping buy ratings on SSE and United Utilities and a hold rating on Severn Trent, Sharecast reported. That makes the pressure look more like a sector valuation and politics issue than a sudden deterioration in National Grid’s operations.
Income investors still have a near-term date on the calendar. National Grid’s final dividend for 2025/26 is 32.14p per ordinary share, payable on July 23 to qualifying shareholders, and the ordinary-share scrip election deadline is June 18. A scrip dividend lets investors take new shares instead of cash, which can preserve company cash but may increase the share count.
The risk is that the same forces supporting the investment case also strain it. If interest costs stay high, UK policy becomes less friendly, regulators limit allowed returns, or new grid projects face planning and supply-chain delays, the £70 billion programme could weigh on valuation before it lifts earnings. The next test is whether National Grid can turn the latest connection momentum into funded projects that earn acceptable regulated returns without pushing debt, dilution or politics back to the front of the story.
