The UK government has approved a non‑material change to the Norfolk Boreas development consent order, in force from 19 December 2025. The decision, issued by the Department for Energy Security and Net Zero (DESNZ), confirms that RWE Renewables UK can use a new compensation route if on‑the‑seabed measures prove unworkable in part.

At the centre of the change is how damage to protected seabed features inside the Haisborough, Hammond and Winterton Special Area of Conservation (HHW SAC) is compensated. The original package required a fixed amount of marine debris clearance before cable installation in the SAC. That rigid trigger has been removed and replaced with an evidence‑led fallback: when agreed works cannot be completed in full, the developer may make a Marine Recovery Fund payment instead, subject to the Secretary of State’s written approval and confirmation from Defra on sums due.

The Order also tidies definitions and coordinates, and retains strong accountability. Norfolk Boreas Limited remains the undertaker. Any switch to fund‑based compensation must be signed off by the Secretary of State, who will only do so once Defra confirms the Marine Recovery Fund can be used and has priced the contribution. This keeps the obligation to restore nature in play even when conditions at sea limit physical interventions.

The Marine Recovery Fund itself is now live in law. Regulations that commenced on 17 December 2025 enable payments to be pooled and directed to strategic habitat projects, creating a route to deliver compensation at scale when project‑by‑project measures fall short or need to be combined.

Oversight has been tightened. Results from seabed monitoring must be submitted at least annually to the Secretary of State, the Marine Management Organisation (MMO) and the relevant statutory nature conservation body. If monitoring shows that measures are not improving the HHW SAC’s condition, new proposals must be tabled and, once approved, carried out. The MMO remains the enforcing authority for deemed marine licences inside development consent orders, including post‑consent monitoring and variations.

Why this matters ecologically is clear. The HHW SAC spans sandbanks and biogenic reefs off the Norfolk coast, including reefs formed by the tube‑building ross worm Sabellaria spinulosa. These habitats support diverse seabed life and are sensitive to disturbance from trenching and cable protection. Any compensation has to genuinely improve condition, not just balance a ledger.

Recent evidence collated for Natural England underscores that placing rock or other hard material on sandbank MPAs can lock in changes to natural sediment movement and keep sites in unfavourable condition. That is why clear, measurable outcomes and adaptive management are essential when projects interact with mobile sandbanks.

Practically, Norfolk Boreas must keep delivering its benthic implementation and monitoring plan, guided by a benthic steering group, and file a completion report when activities finish. If some planned debris removal proves impossible, the Order now allows an adaptive pivot: make the agreed Marine Recovery Fund payment, secure approval, and move ahead-while continuing to meet any payment schedule set out with Defra.

For coastal communities and readers who follow this zone closely, the signal is constructive. The policy shift doesn’t lower the bar; it keeps ecological recovery deliverable when the North Sea refuses to play ball. The test now is transparency: publish monitoring data in plain English, show how compensation money is targeted, and prove that sandbanks and reefs are trending back to favourable condition under MMO and Natural England scrutiny.
