National Grid PLC filings document foreign-issuer disclosures for a U.K.-incorporated utility whose ADRs trade under NGG. The company's Form 6-K reports furnish London Stock Exchange announcements covering total voting rights, treasury shares, Director/PDMR shareholding notifications, scrip dividend mechanics, and ADR-related dividend issuance.
The filing record also includes operating and regulatory updates for National Grid's electricity transmission and distribution businesses, including financial framework disclosures, RIIO-T3 matters, pre-close results updates, and debt-market documents such as supplementary prospectuses for the Euro Medium Term Note Programme involving National Grid plc and National Grid Electricity Transmission plc.
National Grid plc furnished a Form 6-K updating its share capital and voting rights and disclosing routine PDMR share purchases. As of 30 September 2025, registered capital was 5,191,884,002 ordinary shares, including 230,434,106 held in treasury, leaving 4,961,449,896 shares with voting rights for disclosure calculations.

National Grid plc filed a 6-K attaching three London Stock Exchange announcements: a Voting Rights update, a Notification of PDMR transactions and publication of a Prospectus. The Voting Rights notice states the company had 5,191,884,002 ordinary shares as of 31 July 2025, of which 230,653,898 were treasury shares, leaving 4,961,230,104 shares with voting rights to be used as the denominator for FCA disclosure calculations. The Prospectus relates to a €20,000,000,000 Euro Medium Term Note Programme and has been submitted to the National Storage Mechanism; a link to the published PDF is provided.
National Grid plc has submitted its response to Ofgem's RIIO-ET3 Draft Determination, welcoming the regulator's commitment to an £80 billion electricity transmission investment plan and changes to the financial package since the Sector Specific Methodology Decision. The company says the Draft Determination does not fully recognise the practical challenges of delivering a two-and-a-half-fold increase in transmission investment and has proposed changes to ensure the final framework is investable—by improving baseline returns and incentives—and workable—by simplifying funding mechanisms and reopener decision-making. National Grid will continue engagement with Ofgem ahead of the Final Determination in December and points to an executive summary of detailed responses on its RIIO-T3 homepage. The announcement includes a standard cautionary statement about forward-looking statements and risks.
National Grid has agreed to sell its Grain LNG business to a consortium including Centrica plc and Energy Capital Partners (part of Bridgepoint). The terms comprise total proceeds of approximately £1.66 billion, including a pre-completion dividend, with the final consideration subject to customary completion adjustments.
The company says the sale advances its previously communicated strategy to streamline the business and focus on networks. Grain LNG, held through two wholly owned subsidiaries, owns and operates the UK’s largest LNG importation terminal under long-term take-or-pay contracts and is described as playing an important role in securing UK gas supply. Completion is subject to customary government and regulatory approvals and, subject to clearances, is expected to occur later this year.
National Grid plc (NGG) has filed a Form 6-K outlining the share issuance connected to its FY 2024/25 final dividend scrip alternative. The company has applied to the FCA and the London Stock Exchange for 59,266,294 new ordinary shares to be admitted to the Official List and to trading. Dealings and dividend payment are scheduled for 17 July 2025 and the new stock will rank pari passu with existing shares.
Under the Scrip Dividend Scheme, 58,457,054 ordinary shares will be allotted at 1,040.40 p per share, while 161,848 American Depositary Receipts—equivalent to 809,240 ordinary shares—will be issued to US holders at US$70.3102 per ADR. The programme allows shareholders to receive equity in lieu of cash, supporting the company’s liquidity but increasing the overall share count. No earnings, cash-flow data, or forward guidance accompanies the filing.
National Grid plc (NGG) has filed a Form 6-K disclosing Ofgem’s Draft Determination for the RIIO-ET3 price-control period covering April 2026–March 2031. The draft relates to National Grid Electricity Transmission (NGET) and follows the company’s final business plan submission in December 2024. Ofgem continues to acknowledge the need for "significant levels of investment" in the UK transmission network and has proposed allowance decisions for a subset of projects; the remainder will be assessed through in-period mechanisms.
National Grid reiterates its intention to deploy around £60 billion of group-wide capital expenditure between now and March 2029, underscoring the scale of network expansion required to meet rising electrification and decarbonisation targets. Management will scrutinise the draft package to determine whether it offers an "investable" financial framework, highlighting that further progress on incentive mechanisms is still required to balance consumer value with shareholder returns.
The company will engage with Ofgem through the consultation phase leading to a Final Determination expected in December 2025. Securing an attractive allowed return, incentive upside and timely cost recovery will be critical to funding the planned investments while preserving credit metrics and dividend capacity. The filing contains extensive forward-looking-statement disclaimers but no new earnings guidance.
