Published: September 2026 | Industry Policy Update
1. Policy Overview
Starting from 1 April 2026, the UK government officially eliminated import tariffs on 33 categories of offshore wind equipment, including offshore wind power cables, substation auxiliary cables, and wind turbine electrical systems. Previously subject to a 2% import duty, these critical cable products now qualify for zero tariffs under the new authorised-use policy released by the UK Department for Business and Trade.
The new tariff exemption is part of the UK’s Clean Energy Superpower strategy, supporting the record-breaking 8.4 GW / £22 billion offshore wind pipeline confirmed in the UK’s 7th Contracts for Difference (AR7) auction. The policy aims to lower renewable energy project costs, accelerate offshore wind deployment, and strengthen Britain’s energy independence before the 2030 50GW offshore wind target.
2. Which Cable Products Qualify for Zero Tariff?
Based on the official UK tariff amendment document (UKSI 2026/253), the zero-tariff policy applies only to offshore wind-specific cables under HS code 8544 series and related substation electrical components.
Eligible products include:
- Offshore wind farm power transmission cables
- Substation low-voltage auxiliary cables for offshore & onshore wind stations
- Wind turbine supporting electrical wiring systems
Important clarification: General construction cables, ordinary power distribution cables, and onshore wind cablesdo not qualify for tariff exemption.
3. Core Rule: Authorised-Use Tariff Relief
The UK adopts an Authorised Use mechanism for this zero-tariff benefit. The duty-free privilege is conditional:
- Imported cables must be exclusively used for UK offshore wind projects
- UK importers must declare the end usage to HMRC
- Misuse for general construction will trigger back-duty charges and penalties
For international cable suppliers, this means providing clear project usage documentation to support UK buyers’ customs declarations.
4. What This Means for Global Wind Cable Buyers
The tariff removal directly reduces overall project costs for UK offshore wind developers. With 2% import duty eliminated on core wind cable products, overseas qualified cable manufacturers can deliver more competitive pricing for UK wind farm tenders and EPC projects.
As the UK scales up massive North Sea wind projects (including the landmark Berwick Bank offshore wind farm), demand for high-quality offshore wind cables, durable substation cables, and low-smoke fire-resistant wiring will continue rising throughout 2026–2028.
5. Combined EU CBAM Carbon Border Adjustment Trend
While the UK cuts wind cable tariffs, the EU CBAM (Carbon Border Adjustment Mechanism) is reshaping European cable import standards. Starting from 2028, power cables will be fully included in the CBAM carbon verification scope. European buyers are now proactively requiringproduct carbon footprint reports and full supply chain emission data from cable suppliers.
This creates a new industry threshold: future European & UK wind cable orders will require both cost competitiveness and carbon compliance capability.
