The investment that funds the next five years also re-prices what you must prove.
On 4 December 2025 Ofgem’s RIIO-3 Final Determinations confirmed £28bn of network investment funding for 2026–2031 — the opening tranche of what Ofgem estimates as a ~£90bn grid programme by 2031. The money is real — but so is the bar that comes with it. Below: the nine dated changes already in the record, newest first, and the specific exposure each one puts on you. Not a forecast — what has already happened.
Nine dated changes. Each one puts something specific at risk.
On 10 February 2026 DESNZ published the Allocation Round 7a results — Solar PV 4,905.01 MW, Onshore Wind 1,306.18 MW and Tidal Stream 20.90 MW — the second part of Contracts for Difference Allocation Round 7, after the offshore-wind result of 14 January. Each awarded project gains a 15-year indexed strike-price contract; whether yours cleared decides if you hold a route to market or wait for AR8.
On 14 January 2026 the government announced 8,245.00 MW of offshore wind plus 192.50 MW of floating offshore wind, at clearing strike prices of £91.20/MWh (England) and £89.49/MWh (Scotland) in 2024 prices. The order book is real; built capacity still depends on each named project reaching final investment decision, and on proving deliverability at a sub-£92/MWh price.
On 8 December 2025 NESO confirmed its reformed pipeline under the Ofgem-approved “first ready, first connected” rules (approved 15 April 2025), clearing a queue of more than 700 GW and prioritising 283 GW of generation and storage plus 99 GW of transmission-connected demand — while more than 300 GW does not move forward. Your place in the queue, and your connection date, now turn on Gate 2 readiness criteria.
On 12 November 2025 the government introduced the Cyber Security and Resilience Bill to Parliament, reforming the 2018 NIS Regulations to bring managed service providers, data centres, large load controllers and “critical suppliers” into scope and toughen duties on essential energy services. The Bill is before Parliament; its duties take effect only on enactment — but a “critical supplier” designation will reach subcontractors your contracts may not yet cover. The EU’s NIS2 and CER Directives already bind energy operators from October 2024.
On 7 November 2025 China’s MOFCOM and Customs suspended Announcement No. 61’s heavy-rare-earth and permanent-magnet export-licence controls — which bite wherever Chinese-origin rare earths reach 0.1% of an item’s value — until 10 November 2026. Under Chinese administrative law the rule stays legally intact and can be switched back on without new legislation. The dependency in your wind-generator magnets never left; only its enforcement is paused.
The fourth National Security and Investment Act annual report (1 April 2024 – 31 March 2025) records Energy as one of the 17 mandatory-notification sectors and the third most common sector for a final order — five of the 17 made — across 1,143 notifications and 56 call-ins. A change of control over an energy asset is among those most likely to be screened, conditioned or unwound.
The Great British Energy Act received Royal Assent on 15 May 2025, establishing a publicly-owned clean-energy company backed by a committed £8.3bn of new capital over this Parliament (confirmed at the June 2025 Spending Review, with about £2.5bn ring-fenced for nuclear). It is a forward commitment, not money yet drawn — but it sharpens the contest for sites, supply chain and offtake in offshore wind, grid and SMR.
On 25 February 2025 the IEA reported, on its early-2025 industry survey, that large power transformers now take up to four years to secure and HVDC cables beyond five, with lead times for both almost doubled since 2021 and transformer prices up around 75%. The supply of certain grid components is concentrated among a few top-tier suppliers — your energised date is hostage to an order book you cannot bypass.
On 13 December 2024 DESNZ published the Clean Power 2030 Action Plan, setting out the government’s own estimate of around £40bn of investment a year between 2025 and 2030 — roughly £30bn in generation and £10bn in transmission annually, much of it expected to be private — building on NESO advice of 5 November 2024. If your project is not lined up against the 2030 plan, you are competing for capital and queue position it has already pointed elsewhere.
