UK ministers have unveiled plans to cut steel import quotas by 60% from July and introduce a 50% tariff on volumes exceeding those limits — a move designed to protect domestic producers but likely to have knock-on effects across the construction supply chain.
The strategy also sets a target for UK steel to meet up to 50% of domestic demand, up from around 30% כיום, supported by up to £2.5bn in investment funding.
While the policy is being framed as essential for national security and infrastructure resilience, industry leaders have warned it could significantly increase costs for contractors and fabricators.
Jonathan Clemens, chief executive of the British Constructional Steelwork Association, said the measures risk making key materials more expensive for businesses further down the supply chain.
“For all the rhetoric about sovereign capability and backing British industry, this strategy will make essential products more expensive for the downstream businesses that actually turn steel into buildings, bridges and infrastructure,” he said.
“The result will be higher costs across construction, including projects commissioned by the government itself.”
The warning comes as contractors are already contending with tight margins and ongoing volatility in material prices.
The government maintains that imports will continue and that quota levels have been calibrated to preserve supply. However, the scale of the reduction — combined with steep tariffs — is expected to tighten availability and push prices higher, particularly for specialist steel products that are not widely produced within the UK.
The strategy also confirms that electric arc furnaces will play a central role in the future of UK steelmaking, accelerating the transition toward recycled, lower-carbon production methods.
