The UK government has announced it will effectively remove import tariffs on 33 specific industrial goods critical to offshore wind production from 1 April.
This allows UK-based manufacturers to import the designated components at zero or reduced duty rates, provided the goods are used exclusively for producing offshore wind infrastructure and processed within specified timelines.
The change is expected to save British companies millions of pounds annually, freeing up capital for reinvestment in the sector.
Overall, the 33 categories cover key inputs for producing rotor blades, rotors, cables, and auxiliary/low-voltage systems incorporated into wind turbines, onshore and offshore substations, and related infrastructure.
The government frames the decision as a strategic use of trade policy to advance its ‘Clean Energy Superpower’ mission. Offshore wind is highlighted as a cornerstone of the UK’s energy transition, already the country’s largest renewable source, and notably cheaper to produce and maintain than new gas projects, according to Levelised Cost of Energy metrics.
By lowering production costs for domestic firms, the measure aims to make UK manufacturers more competitive, encourage growth in the supply chain, and support broader goals of addressing climate change while enhancing energy security and independence from volatile fossil fuel imports.
The announcement comes on the heels of a blockbuster Contracts for Difference (CfD) Allocation Round 7 in January 2026, which secured a record 8.4 gigawatts (GW) of new offshore wind capacity and £22 billion in investments.
That haul, enough to power the equivalent of over 12 million homes, includes major projects like Berwick Bank in the North Sea, Scotland’s first new offshore wind development since 2022 and one of the world’s largest planned farms.
