The UK Government has announced a new tariff measure that will remove offshore wind tariffs on 33 industrial goods beginning 1st April 2026. This move is meant to lower costs for manufacturers and strengthen the country’s clean energy supply chain. By eliminating these offshore wind tariffs, the government expects offshore wind energy manufacturers to save millions of pounds annually while boosting domestic production capacity. The measure is designed to allow British manufacturers to produce key components more cost-effectively, enabling companies to reinvest in growth across the clean energy sector. Officials said the decision forms part of broader efforts to support the UK’s Clean Energy Superpower mission and accelerate the expansion of renewable energy infrastructure.
According to the government, reducing offshore wind tariffs will support the development of the UK’s largest source of renewable energy while helping to address climate challenges and enhance national energy security. Offshore wind generation is already a major contributor to the country’s energy mix and is significantly more cost-effective compared with alternative options. Based on the Levelised Cost of Energy (LCOE) industry metric, offshore wind is around 40% cheaper to produce and maintain than new gas projects. The tariff policy follows a strong wave of investment in the sector, highlighted by the January 2026 Contracts for Difference Allocation Round 7, which secured a record 8.4GW of offshore wind capacity and £22bn in investment. That level of development is expected to generate enough clean energy to power the equivalent of more than 12 million homes. The projects awarded include Berwick Bank in the North Sea, the first new Scottish project since 2022 and one of the largest planned offshore wind developments worldwide.
The announcement reflects the UK Government’s intention to align industrial and trade policy with long-term clean energy objectives. By removing offshore wind tariffs, policymakers aim to demonstrate how trade tools can be used strategically to support domestic industries while driving economic growth. The initiative also supports commitments outlined in the Trade Strategy, which seeks to ensure international trade policy works alongside environmental goals. The strategy prioritizes securing access to the goods, services, and technologies necessary to accelerate the clean energy transition.
Under the new framework, an authorised use measure will conditionally reduce the import tariff on qualifying goods to zero at the border. The government said this approach ensures that tariff reductions benefit the renewable energy supply chain while still protecting UK manufacturers from competition from low-cost imports in other sectors that may use similar materials. Through the Authorised Use procedure, UK-based traders can access reduced or zero customs duty rates on imported goods provided the products are used for a specified purpose and processed within a defined timeframe. Eligible imports include items used in manufacturing cables, rotors, rotor blades, and auxiliary and low-voltage systems required for both onshore and offshore substations or wind turbines, as outlined under the Authorised Use procedure.
