Rolls-Royce’s small modular reactor (SMR) division posted a £115 million loss in 2024, widening from the previous year’s £78 million shortfall. The subsidiary, which is still pre-revenue, reported a rise in government grant income from £65.4 million to £86.9 million, according to recent Companies House filings.
The division continued to grow its workforce, increasing headcount from 590 to 714 employees during the period. Rolls-Royce has previously indicated that the SMR business is expected to move towards profitability and positive free cash flow by the end of the decade.
The ongoing investment reflects the company’s strategic commitment to developing small modular reactor technology as part of the UK’s long-term clean energy ambitions.
