6% domestic today, a 30% target by 2035, a 34-mineral critical list.
The Vision 2035 Critical Minerals Strategy targets lifting the UK’s domestic share of critical-mineral needs from approximately 6% today to 30% by 2035 — a fivefold expansion of domestic mining and recycling against a denominator that is itself rising sharply.
The Strategy introduces binding targets: 10% domestic production, 20% recycling, and a maximum 60% reliance on any single foreign supplier for each mineral — supported by up to £50 million of funding for UK extraction, refining, processing and recycling.
By 2035, annual UK demand for copper will approximately double and demand for lithium will rise by approximately 1,100% (a 12-fold increase). The Eastern Green Link programme illustrates the materials concentration: EGL1 alone awarded £1.8 billion of contracts, with raw materials 70–80% of overhead-cable cost.
Domestic production, recycling and procurement diplomacy — three legs of one Strategy.
The 30% target splits into 10% domestic production + 20% recycling, with a 60% single-supplier cap as the third leg. Recycling is the larger and more tractable half — battery recycling (lithium, cobalt, nickel, graphite) is at industrial scale globally and being established in the UK. Domestic production (Cornish Lithium, British Lithium, Pensana) is emerging but small against the requirement.
The HVDC supply chain — cables, converter stations, transformers — is concentrated in approximately 5–6 manufacturers globally (Prysmian, Nexans, NKT, Hitachi Energy, Siemens Energy, GE Vernova). UK domestic capacity is modest; the GBE Supply Chain Fund (£300m, Gap 24) is one lever to build it.
The volume's argument
UK Clean Power 2030 and 2035 delivery depends on a critical-minerals supply chain that has been historically import-dependent. The Critical Minerals Strategy is necessary but not sufficient; matching industrial policy, public-finance support and international procurement diplomacy are operationally complementary. The policy response is in place; the execution discipline matters.
The shape of this volume. Section 1 sets out the headline figures. Section 2 develops twelve findings, each confidence-annotated. A chapter-weight pull at p. 14 anchors the argument. Section 3 sets out the Vision 2035 Strategy and the BGS list. Section 4 develops the demand trajectories and the HVDC supply chain. Section 5 isolates the domestic build-out and the forward outlook. Section 6 makes recommendations, with a one-page tear-out at p. 25.

Vision 2035 reframes UK critical minerals from market matter to security matter.
The 2025 refresh of the UK Critical Minerals Strategy — published as Vision 2035 — is a substantial change from the 2022 Resilience for the Future foundational document. The foundational Strategy framed critical minerals as a market and supply-chain matter; the 2025 refresh frames them as a national-security and industrial-strategy matter, with binding numerical targets and reciprocal trade and procurement consequences. Three changes are material: binding numerical targets (30% UK supply, 10% production, 20% recycling, 60% max single-supplier reliance); the expanded 34-mineral list; and an explicit "supply chain stack" — investment, regulation, trade and procurement working in coordination, not market-driven solutions alone. For grid and energy developers, material supply-chain risk is now UK Government policy as well as commercial procurement.

Finding 02 · HIGH
The 6%-to-30% transition is the operative quantification.
The single most operative quantification in the Strategy is the move from approximately 6% UK domestic share of critical-mineral needs today to 30% by 2035 — a fivefold expansion of domestic mining and recycling in roughly ten years. The arithmetic is challenging: UK demand is itself rising sharply, driven by Clean Power 2030, EV manufacturing, electronics and defence, so the 30% share applies to a denominator that is itself increasing. Achieving 30% of an expanded base requires substantially more than 5× growth in domestic supply in absolute terms. The Strategy frames the 10% production + 20% recycling split as the route, with recycling the larger share — reflecting both the maturity of recycling for lithium, cobalt and nickel and the relative ease of scaling recycling versus opening new mines.
