IN Brief:
- Group revenue increased to £5.563bn and underlying profit from operations rose to £119m in the first half of 2026.
- Support Services profit increased to £66m, with strong growth in UK power transmission contributing to the improvement.
- Balfour Beatty raised several full-year guidance measures while its order book increased to £22.9bn.
Balfour Beatty has raised several full-year guidance measures after stronger first-half earnings, with UK power transmission contributing to a marked improvement in its Support Services operation.
Group revenue for the half year reached £5.563bn, up from £5.150bn in the corresponding period of 2025. Underlying profit from operations increased to £119m from £77m, while profit from the earnings-based businesses rose to £153m from £108m.
The company’s order book stood at £22.9bn at the end of the period, compared with £22.7bn at the end of 2025 and £19.5bn a year earlier. That provides a substantial pipeline across the group’s UK, US, and Asian construction and infrastructure operations, although the composition varies between secured contracts and expected work under frameworks.
Support Services produced one of the clearest movements in the half-year figures. Revenue increased from £662m to £727m, while underlying profit from operations rose from £46m to £66m, giving the division a 9.1% margin.
Balfour Beatty attributed the improvement to strong growth in power transmission, where investment in the UK electricity network is creating longer-duration programmes for civil engineering, substations, overhead lines, underground cable systems, and associated specialist services.
Transmission work differs materially from shorter-cycle commercial construction. Projects frequently extend over several years, pass through staged regulatory and procurement processes, and require large quantities of specialist labour and engineering capability before physical construction reaches its peak.
For major contractors, that can provide better workload visibility but also creates a resource-planning problem. The same engineers, project managers, designers, plant, temporary works specialists, and supply chain businesses may be required across electricity, rail, roads, water, nuclear, and other nationally significant programmes at the same time.
Balfour Beatty’s UK Construction division was comparatively stable during the period. Revenue was £1.569bn against £1.563bn a year earlier, while underlying profit from operations was £54m and the margin stood at 3.4%.
The prior-year comparison included a £10m one-off credit, making the movement in reported divisional profit less informative than the underlying operating trend. Construction margins at this scale remain narrow enough that the commercial performance of a relatively small number of large projects can materially affect group results.
That is one reason the quality of the order book matters alongside its absolute size. A large backlog does not protect a contractor from poorly allocated risk, inflation exposure, design changes, programme delay, or subcontractor failure if the work was secured on inadequate commercial terms.
Balfour Beatty’s current strategy has emphasised growth markets in which long-term infrastructure demand is relatively visible. UK energy is one of those markets, supported by transmission investment associated with generation connections, electrification, network reinforcement, and the replacement of ageing assets.
The construction consequences extend beyond grid specialists. New transmission capacity can determine whether data centres, industrial sites, housing, renewable generation, and other developments obtain the connections required to operate, making electricity infrastructure increasingly intertwined with the programme risk of projects that would once have treated power as a later-stage utility issue.
Cash performance also strengthened during the half. Average recourse net cash increased to £1.616bn from £1.212bn at the end of 2025, prompting Balfour Beatty to raise its full-year average net cash guidance by £200m to between £1.5bn and £1.7bn.
The half-year dividend increased by 12% to 4.7p per share, while the company reported £102m of share buybacks completed during the period. Those shareholder returns sit alongside continued investment requirements across a business carrying almost £23bn of future work.
Full-year guidance for underlying profit from the earnings-based businesses has also been increased from high single-digit percentage growth to low double-digit percentage growth. Net finance income guidance moved upwards to between £35m and £40m.
Those revisions reflect a first half in which the strongest improvement was not spread evenly across every construction market. UK Construction revenue was broadly flat, while Support Services benefited directly from expanding power transmission activity and US Buildings contributed to growth elsewhere in the group.
The split is useful when assessing the wider contracting market. Large infrastructure businesses can post rising group revenue and profit while individual construction sectors remain subdued, because regulated energy, maintenance, and long-duration infrastructure programmes operate on different cycles from commercial development or housebuilding.
Balfour Beatty enters the second half with more secured and framework workload than it carried a year ago and stronger cash guidance, but delivery now has to absorb the increased volume without giving back the margin improvement through resource pressure or project execution.
The power transmission pipeline is already contributing to reported profit. As more network programmes move into full construction, the constraint is likely to become less about whether work exists and more about how much qualified delivery capacity can be mobilised without weakening commercial discipline.
