The UK government has officially launched Allocation Round 8 (AR8) of its Contracts for Difference (CfD) scheme, marking the next stage in one of the country’s most important mechanisms for supporting renewable electricity generation.
The annual auction gives developers of renewable energy projects the opportunity to secure long-term revenue certainty, helping unlock private investment in technologies including offshore wind, onshore wind and solar. For AR8, offshore wind alone could attract between £20 billion and £30 billion of investment.
Alongside the latest auction, the government has introduced several changes designed to improve value for money, increase confidence that successful projects will be delivered and support progress towards its Clean Power 2030 ambition.
What is a Contract for Difference?
The Contracts for Difference (CfD) scheme is the government’s mechanism for supporting investment in renewable electricity generation.
It gives developers greater certainty over future revenues by agreeing a fixed “strike price” for the electricity they generate. If wholesale electricity prices fall below that level, the scheme tops up the difference. If prices rise above it, generators pay the difference back, helping protect consumers from volatile energy prices.
By reducing financial risk, the scheme makes it easier for developers to secure investment in large renewable energy projects such as offshore wind and solar.

What’s new in Allocation Round 8?
While the overall structure of the Contracts for Difference scheme remains the same, Allocation Round 8 introduces several changes intended to improve value for money, increase project delivery and support emerging renewable technologies.
For the first time, ministers will be able to set the final budget for solar, onshore wind and fixed-bottom offshore wind after reviewing confidential bid information. This allows the government to better match procurement with market conditions and secure greater value for consumers.
The auction also introduces greater flexibility around clearing prices, allowing different prices to be awarded based on factors such as project technology, location or size where this improves overall outcomes.
To improve confidence that successful projects will be delivered, only schemes with advanced Gate 2 grid connection status will be eligible to participate.
Emerging technologies also receive additional support. Floating offshore wind projects will benefit from extended delivery times to reflect their longer construction periods, while a new technology category has been introduced for deepwater offshore wind developments.
The government has also chosen to maintain the Administrative Strike Prices introduced in Allocation Round 7, providing greater consistency between auction rounds while continuing to encourage competitive bidding.
Why AR8 matters
Allocation Round 8 is widely expected to be one of the most important CfD auctions to date.
Given the long lead times involved in developing renewable energy infrastructure, it represents one of the final major opportunities to secure projects capable of contributing towards the government’s Clean Power 2030 target.
The results will also provide an indication of investor confidence in the UK energy market and reveal how competitively different renewable technologies can continue to deliver new generation capacity.
With offshore wind alone expected to unlock up to £30 billion of private investment, the auction is likely to play a significant role in shaping the UK’s renewable energy pipeline for the remainder of the decade.
Key dates for CfD Allocation Round 8
Applications for Allocation Round 8 will open on 20 July and close on 7 August 2026.
Following eligibility checks, the auction will take place later this year, with successful projects expected to be announced between November 2026 and February 2027.
Unlike the previous allocation round, results across all eligible technologies are expected to be published at the same time.
