MPs Criticise Sizewell C Financing as Bad Deal for Taxpayers

Public Accounts Committee Warns of Escalating Nuclear Costs

Parliament’s Public Accounts Committee (PAC) has issued a critical assessment of the funding arrangements for the Sizewell C nuclear power station, describing the current financial model as a "terrible deal for the UK taxpayer." In a report published on 28 October, MPs demanded rigorous oversight of the project, including mandatory six-monthly updates covering construction progress, total expenditure, and projected returns for private investors.

The parliamentary watchdog expressed serious concern that the risk profile heavily favours private financiers while leaving the British public exposed to potential cost overruns. Sizewell C, planned for the Suffolk coast, is central to the UK government's long-term energy security strategy, but its complex Regulated Asset Base (RAB) model has drawn sharp criticism for adding charges to consumer energy bills before the plant generates electricity.

Broader Impact on Infrastructure and Construction Resources

Large-scale infrastructure projects of this magnitude place immense pressure on the UK's broader construction supply chain. The call for tighter financial controls reflects growing anxiety over major civil engineering mega-projects, where shifting budgets and delayed timelines risk cannibalising skilled labour and raw materials from regional residential and commercial sectors.

If cost controls fail, public funding diverted to stabilize infrastructure guarantees cannot be deployed into regional development or localized trade training programmes, putting additional strain on a industry already facing severe skills shortages.

What This Means for Tradespeople and Builders

What does this mean for a UK tradesperson or DIYer actually buying this kit — does it change what they should pay, buy, or watch out for?

While this parliamentary warning does not directly alter the over-the-counter price of timber, fixings, or power tools at trade counters today, it highlights long-term pressures on the wider trade ecosystem. Mega-projects like Sizewell C absorb huge volumes of heavy building materials and skilled civil contracting workforce. Increased scrutiny may lead to budget recalibrations, but contractors operating in the supply chain should anticipate continued tight competition for specialist labor and potential spillover effects on utility-driven energy costs for businesses.
