Westminster has approved a non‑material change to the Norfolk Boreas Offshore Wind Farm Order 2021. Signed on 18 December 2025 and effective from 19 December 2025, the measure refreshes the project’s environmental compensation rules in the Haisborough, Hammond and Winterton (HHW) Special Area of Conservation. The Department for Energy Security and Net Zero published the order on legislation.gov.uk.

The headline change is a new backstop. If the required area of marine debris cannot be cleared to compensate for cable installation and protection within the HHW SAC, the undertaker may apply to make a payment into the Marine Recovery Fund established under section 292 of the Energy Act 2023. Any payment substitutes only for the shortfall in debris removal; this is not a licence to skip the programme entirely.

Using the fund comes with checks. The Secretary of State must judge the approach acceptable in principle and, where the cable corridor impact is shared with Norfolk Vanguard, determine the proportion that relates to Boreas. Defra, or the body operating the fund, must confirm it can take the contribution and quantify the amount due. Only after those confirmations can substitution be approved.

Once approved, cable installation inside the HHW SAC cannot proceed until an implementation and monitoring plan is signed off by the Secretary of State. The undertaker is discharged from further on‑site compensation duties when one of three things happens: the completion report is approved; the full Marine Recovery Fund sum is paid and confirmed; or a contract to pay by instalments is in place and the first instalment is made. If instalments are used, the payment schedule must still be honoured.

The order also removes the previous hard pre‑condition that at least 8.3 hectares of marine debris must be cleared before cable works begin in the HHW SAC. In its place sits a clearer monitoring loop: results must be filed at least annually with the Secretary of State, the Marine Management Organisation and the relevant nature conservation body, with remedial steps implemented once approved if measures prove ineffective.

Governance and drafting are tidied up. ‘Defra’ is now defined, the ‘undertaker’ is confirmed as Norfolk Boreas Limited (Company No. 03722058), and several latitude and longitude points are corrected within the authorised project parameters. Definitions for the Benthic Implementation and Monitoring Plan (BIMP) and the Benthic Steering Group (BSG) are added, pointing to a more formalised approach to evidencing delivery.

For project finance teams, this matters because it converts an uncertain field task into a cash obligation that can be priced, scheduled and insured against. The amount is not set in the order-it must be agreed with Defra-so budgets should carry sensitivity for the eventual quantum. The approvals chain adds timing risk of its own: Secretary of State sign‑off and fund operator confirmation move onto the critical path.

Developers and EPCs should expect closer scrutiny of the BIMP and monitoring evidence, given the substitution can only cover the part of the programme that falls short. For lenders, a signed approval and payment schedule can be easier to diligence and covenant than open‑ended remedial works offshore, potentially reducing drawdown friction.

There is also a coordination point with Norfolk Vanguard because both schemes share a cable corridor. Any application must set out the proportion of debris‑removal responsibility attributed to Boreas once shared impacts are accounted for, which in turn drives how costs are split between the projects.

Our read: this is a pragmatic backstop that aims to preserve environmental outcomes while reducing schedule friction for a nationally significant project. The figure to watch in early 2026 is how Defra prices comparable contributions-those decisions will set reference points for budgets across the UK offshore wind pipeline.
