Balfour Beatty has upgraded its earnings and cash flow forecasts, citing "real momentum" that sets it apart from the broader challenges weighing on the UK construction sector.

The FTSE 250 infrastructure group, which partners with the government on major projects, reported a 17 per cent rise in its order book to £22.9bn for the six months ending June. Revenue climbed eight per cent to £5.6bn, bolstered by growing demand in US housebuilding and the UK power sector.

Balfour Beatty raised its earnings growth outlook from low single-digit to high double-digit growth and increased the upper bound of its net cash forecast from £1.5bn to £1.7bn. Underlying profit surged 42 per cent to £153m, while headline pre-tax profit dipped two per cent to £129m.

Chief executive Phillip Hoare said: "Balfour Beatty enters the second half with real momentum. Our strong first-half performance reflects the quality of our business, the discipline of our execution and, above all, the exceptional contribution of our people in delivering for our customers."

The company's positive trading update stands in contrast to the difficulties engulfing the wider UK construction industry, where housebuilders and materials suppliers have flagged rising costs and weakening private-sector demand.

Government-Backed Infrastructure Drives Growth

On Tuesday, housebuilder Bellway called on the government to reduce stamp duty to spur construction activity. Last month, the chief executive of property portal Rightmove described conditions for UK housebuilders as "among the most difficult experienced since the global financial crisis."

Balfour Beatty, however, pointed to robust growth in the UK's energy, defence, and transport infrastructure sectors as a principal driver of its revenue gains. These sectors have benefited from sustained public spending commitments, including the UK government's National Infrastructure and Construction Pipeline, which outlines hundreds of billions in planned investment over coming years, as well as ongoing funding tied to grid modernisation and the transition to net-zero power generation.

"These markets are supported by strong funding commitments and enduring customer demand, providing attractive growth opportunities over the near to medium term," the company told shareholders.

The strength of demand in these areas allows Balfour Beatty to be "disciplined and selective" in choosing its projects, the firm added.

Major contract wins so far this year include a £325m power transmission project in Scotland, a £315m road maintenance programme in Warwickshire, and $350m (£259m) in US data centre orders. The US data centre contracts reflect broader demand from hyperscale cloud providers and AI-driven infrastructure buildouts, while the UK's transmission investment ties directly to the national goal of decarbonising the electricity grid by 2035.

Analysts at Peel Hunt commented: "We expected a strong performance and Balfour Beatty delivered again," noting that the firm's revenue visibility "continues to drive a higher quality of growth."

Alex Pugh, an analyst at Freetrade, said the group has sidestepped the difficulties facing private-sector housebuilders by concentrating on demand "in areas where spending is hard to avoid: power networks, transport, defence and US buildings."

"This is a company in the right place at the right time. The balance sheet is doing some heavy lifting too. Strong cash generation means Balfour can fund growth and still keep investors sweet with dividends and buybacks," Pugh added.

Balfour Beatty shares rose more than eight per cent on Wednesday to 942p.
