Lower Thames Crossing Gets £590M — 22,000 Construction Jobs Over Six Years
What happened
The UK government has allocated £590 million to the Lower Thames Crossing as part of its 10-Year Infrastructure Strategy, with the remaining cost (total estimate: £9.2–10.2 billion) expected to come from private finance. Construction is due to begin in 2026 after development consent was granted in March 2025.
The project will stretch 14.5 miles from Tilbury in Essex to Gravesend in Kent, including 4.2km of twin-bore tunnels beneath the Thames. It's one of the largest infrastructure projects in the UK.
The numbers are significant: an estimated 22,000 jobs across a six-year build, with over 2,000 construction professionals needed on-site. The project is targeting 45% of its workforce from within 20 miles of the scheme, and will include hundreds of apprenticeship and traineeship places.
Major contractors already involved include Balfour Beatty, Murphy Group, Bouygues Construction, and AtkinsRéalis.
What this means for tradespeople
While a mega-infrastructure project like this isn't directly about domestic trades, the ripple effects hit local tradespeople in two ways.
First, the opportunity: subcontracting work for utilities, electrical installations, and fit-out will flow down the supply chain to smaller firms in Essex and Kent. If you're a sparky, plumber, or general builder within 20 miles of the route, this is worth watching.
Second, the competition squeeze: 22,000 jobs will pull skilled workers out of the domestic market. For self-employed tradespeople who stay focused on residential work, that means less competition from other tradespeople — but also harder to find subcontractors and labourers when you need them. Build your reputation now so customers come to you directly.
This sits alongside the broader UK infrastructure pipeline — the government's 10-Year Strategy commits at least £725 billion over the decade, creating sustained demand for skilled trades at every level.
