The UK Government has announced that the next Contracts for Difference (“CfD”) auction, Allocation Round (“AR”) 8, will open in July 2026, continuing the transition toward an annual auction cycle. This is in line with the UK Government’s updated energy security and decarbonisation strategy, and part of a wider package of energy interventions to boost the UK’s energy security.
The confirmation of AR8 follows a landmark previous round, the two-part AR7 (for offshore wind) and AR7a (for all other renewable technologies), the results for which were announced in early 2026.
The announcement follows the December 2025 consultation on AR8, which closed at the end of January. On 20 March 2026, Government also published a response to some of the legislative amendments proposed in that consultation, in order to improve the efficiency of the CfD scheme in certain respects.
This article considers the Government’s AR8 announcement, examines key lessons emerging from the AR7/AR7a results, and highlights potential implications for developers preparing for the next allocation round.
AR8: an auction centred on energy security
The Government has confirmed via its March 2026 update on energy security that AR8 will open in July 2026. The announcement forms part of a wider package intended to “go further and faster” in delivering domestic clean power and strengthening the UK’s long‑term energy resilience, and was accompanied by announcements relating to the widening of availability for low cost “plug-in” solar panels for households, the acceleration of devolved funding rounds for the new £15bn Warm Homes Plan announced earlier this year, and the announcement that Government will be working with the Competition and Markets Authority (CMA) to prevent price gouging by fuel suppliers (in the face of the spike in prices for heating oil and road fuel).
AR7: Fixed‑bottom and floating offshore wind
AR7 was launched in the context of industry concerns about the extent of offshore wind participation and deliverability, particularly in light of 2023’s AR5 failing to attract a single bid from an offshore wind project. In AR5, the Government was criticised that the Administrative Strike Price (“ASP”) (the maximum price per MWh permitted) had been set too low to make offshore wind projects viable. Reforms introduced ahead of AR7, including relaxed eligibility criteria, the shift to 20-year contract terms and higher ASPs for key technologies, materially strengthened investor confidence and bankability.
Published in two waves - (1) AR7 for fixed bottom and floating offshore wind, the results for which were released on 14 January 2026, followed by (2) AR7a for onshore wind, solar PV, and tidal stream released on 10 February 2026, the round in its totality saw a record-breaking 201 CfDs awarded, locking in 14.7 GW of clean energy across multiple technologies.
AR7 delivered a total of 8,437.5 MW across 12 fixed and floating offshore wind projects; 9 fixed bottom projects in England and Wales (totalling 6,865 MW, clearing at £91.20/MWh against an ASP of £113/MWh), and one project in Scotland (at 1,380 MW clearing at £89.49/MWh). The remaining two projects were floating projects totalling 192.5 MW at a clearing price of £216.49/MWh against an ASP of £271/MWh. Clearing prices were around 19 - 21% below the relevant ASPs, highlighting substantial savings and improved project economics for both developers and consumers. Full results can be found here.
Emerging technologies gained further momentum. Tidal stream cleared well below ASP, indicating that technology specific budget uplifts are achieving their intended purpose. As AR8 approaches, it is expected that the Government will refine and expand support for innovation categories in line with its wider objective of encouraging greater technology diversity.
AR7 outcomes and what they signal for AR8
AR7 demonstrated several clear takeaways for future allocation rounds. Eligibility reforms widened participation and are likely to go further, with the removal of full planning consent as a pre‑application requirement for fixed‑bottom offshore wind unlocking significant bid volumes. AR8 may refine or expand these flexibilities, particularly for projects with later delivery profiles or higher structural costs, such as large offshore wind and other capital‑intensive or grid‑constrained technologies, where targeted measures such as separate clearing prices or additional delivery years may be necessary to ensure effective competition.
At the same time, early‑stage technologies seem to be benefiting from more structured support. Although tidal stream awards under AR7 were small in capacity terms, they reflected the impact of dedicated ASP increases and bespoke pot structures, a trajectory that AR8 may strengthen depending on budget allocations and Government appetite to expand competitiveness for nascent technologies.
Finally, supply chain factors are now central to auction design. The CfD Clean Industry Bonus Scheme (introduced in AR7) means fixed and floating offshore wind applicants can obtain extra CfD revenue support if they choose to invest in more sustainable supply chains, supporting homegrown manufacturing of components like blades and cables, and targeting economic growth in coastal and industrial areas. AR8 bidders may face more compliance‑focused bid preparation requirements than in any previous round. For more information on the Clean Industry Bonus and its future implementation within the CfD scheme, see our commentary here.
As summarised in our commentary on this issue, developers should keep an eye on the potential changes for AR8 as set out in the Government’s recent consultation on a proposed package of refinements, which include:
- the permanent exclusion of surrendered CfD capacity from future rounds,
- extended commissioning windows for floating offshore wind projects (from 18 to 24 months),
- the introduction of hybrid metering arrangements allowing generators to share balancing mechanism units while recording output separately, and
- a new “Other Deepwater Offshore Wind” technology category to support innovative non-floating deep-water foundation designs.
The consultation also proposes a requirement for projects to hold a “Gate 2” (rather than “Gate 1”) connection agreement in order to qualify for AR8, which would therefore mean that they will need to have reasonably advanced land rights in order to participate – as well as potentially being “strategically aligned” with capacity limits in the Government’s strategic plan.
On 20 March 2026, Government provided initial feedback on some aspects of that consultation relating to improving the efficiency of the scheme, including confirming the following:
- NESO will receive clearer powers to fix errors and handle appeals more efficiently. This includes allowing NESO to correct its own administrative mistakes in CfD application assessments, issue revised decisions, pause the process for affected projects, and consider additional evidence at the “Tier 1” review stage, where it can help resolve minor, non‑material errors made by applicants;
- while applicants will keep their full appeal rights (under the two‑stage, Tier 1 then Tier 2, appeal system), allowing for a more flexible process under which procedures can be updated more easily between rounds; and
- clarifying “pending application” rules to avoid delays and improve fairness. The definition of a “pending application” will be expanded to include applicants still within court appeal windows, ensuring they can submit sealed bids, and several regulations will be clarified so the process runs more smoothly in future allocation rounds.
A separate Government response will be published in due course setting out decisions on the other measures proposed in the December 2025 consultation.
Looking ahead
The Government’s confirmation that AR8 will launch in July 2026 (with applications opening on 13 May 2026) signals its intent to maintain momentum in renewables deployment. This next step in the UK’s trajectory toward a fully decarbonised power sector may help to partially insulate consumers from high energy prices, as well as decoupling wholesale electricity prices from volatile natural gas costs, but also introduces new challenges for developers.
After AR7/AR7a securing a record 14.7 GW and demonstrating resurgent confidence across key renewable technologies, AR8 will open against a backdrop of strengthened competition, improving economics, and continuing policy evolution – but with the added uncertainty and supply chain pressures. With AR7 projects now extending into 2031/32, there is likely to be intensified competition for supply chain capacity with AR8 – and planning and grid bottlenecks remain significant hurdles to successful deployment.
Developers preparing for AR8 should take stock of the lessons from AR7 and AR7a and begin preparations early, as success in AR8 is unlikely to hinge just on technical excellence, but on the ability to anticipate and adapt to an evolving regulatory and market landscape. The sector now awaits the final AR8 parameters and budget, which will determine how the next phase of the UK’s clean energy ambitions unfolds.
