Private housing leads the quarterly decline, as monthly output and new orders rise in September to signal fragile recovery
Construction output in Great Britain fell by 0.7% in the third quarter of 2026 compared with the second quarter, according to Office for National Statistics (ONS) figures. This marks a reversal after the modest quarterly growth recorded earlier in the year.
New work bore the brunt of the contraction, falling by 1.6% over the quarter, while repair and maintenance offered a partial offset with growth of 0.5%. Five of the nine tracked sectors recorded declines in Q3, with private new housing the single largest drag on output, falling by 4.7%.
September provides a late-quarter lift
Despite the quarterly contraction, the monthly picture for September was more encouraging. Construction output rose by 0.8% in September, ending a run of four consecutive monthly decreases — including a revised fall of 0.5% in August and a revised decline of 0.2% in July.
Both new work and repair and maintenance contributed to September's improvement, rising by 0.9% and 0.6% respectively. Infrastructure new work was the standout performer within the month, growing by 3.3% and providing the main contribution to the increase in new work.
The figures offer some reassurance to brokers and lenders active in development finance, though the broader quarterly trend highlights the fragility of conditions on the ground.
New orders recover, but price pressure mounts
Total construction new orders grew by 1.2% — equivalent to £107 million — in Q3 compared with Q2, according to the ONS. The increase was driven primarily by public other new work and private commercial new work, representing a turnaround from the sharp 11.8% contraction recorded in Q2.
That said, pricing pressures in the sector are intensifying. The annual rate of construction output price growth reached 3.2% in the 12 months to September, up from 1.9% in the 12 months to June — a trend that could weigh on scheme viability and affect the development finance products brokers are placing on behalf of clients.
Housing supply implications
The 4.7% fall in private new housing output during Q3 adds to mounting concern about the government's ability to deliver on its housebuilding commitments. The decline follows a prolonged period in which planning uncertainty and weak developer confidence have combined to suppress starts, as recent GDP data has also made clear.
For Neil Leitch, managing director of development finance at Hampshire Trust Bank, the data signals something more troubling than a single quarter's decline. "A fall in private housebuilding output is another reminder of the difficult conditions facing developers," Leitch said. "The concern isn't simply that fewer homes are being built today, but that the pressures behind these figures are also making it harder for housebuilders to commit to their next projects, particularly SME developers who are being squeezed on several fronts."
The ONS released its GDP monthly estimate for September alongside this bulletin, with construction forming a key component of overall economic output.
Leitch was clear that the data carries a broader policy warning. He said: "These figures should be a warning that housing delivery cannot improve sustainably without addressing the conditions developers face. The test of planning reform isn't how many applications enter the system, but how many viable schemes secure consent within the statutory timescales and can actually get built. That means reform must be matched by the people and resources needed to turn applications into timely decisions. Otherwise, we risk losing more SME development capacity at precisely the time the country needs it most."
