Dalkia returns to profit as nuclear and low-carbon work drives growth

Dalkia has delivered a strong financial recovery, with growth across nuclear, facilities management and low-carbon projects driving a significant uplift in performance.

The energy services and engineering specialist reported an 8% increase in turnover to £657m, while pre-tax profit rose sharply to £8.2m, up from £0.3m the previous year.

Underlying performance also improved, with EBITDA more than doubling to £18m, reflecting a stronger operational footing across the business.

Growth has been driven by increased activity in nuclear infrastructure, including work across existing power generation sites and new build projects. A major facilities management contract on EDF nuclear sites has also boosted performance, bringing in more than 1,000 additional staff.

As a result, Dalkia’s order book has grown 17% to £1.3bn, providing a strong pipeline for future work.

Facilities management was a standout performer, supported by the nuclear contract, while its systems integration division also delivered steady growth and improved margins.

However, its energy services arm — focused on large-scale decarbonisation projects in healthcare and education — faced challenges, with delays and cost pressures impacting profitability on complex retrofit schemes.

Despite this, the company has strengthened its financial position, with cash reserves more than doubling to £44m.

Dalkia is now targeting further growth beyond £750m in revenue, supported by acquisitions and expansion into international markets.
