30 Second Briefing
Jones Bros reported a 53% jump in group turnover to £240.5m for the year to March 2026, with its core civil engineering revenue up 55% to £232.8m and capital investment almost doubling to £20m. The contractor’s average workforce rose from 498 to 545 employees, while its carbon energy performance has improved by 22% against a 2020 baseline. Major 2025 work includes Havant Thicket Reservoir in Hampshire, Sanquhar II and North Kyle wind farms in Scotland, large BESS schemes at Uskmouth and Thorpe Marsh, and the Kinmel Bay Coastal Defence Scheme.
Technical Brief
- Capital investment in plant and machinery rose from £10.8m to £20m within one year.
- Workforce expansion of 47 staff implies additional in-house capacity for self-delivery of heavy civils packages.
- Havant Thicket Reservoir involvement positions Jones Bros on UK’s first major reservoir scheme in 30+ years.
- Delivery roles on Sanquhar II and North Kyle wind farms indicate strong exposure to Scottish onshore wind civils.
- Battery energy storage work at Uskmouth and Thorpe Marsh ties the contractor into grid-scale BESS balance-of-plant civils.
- Kinmel Bay Coastal Defence Scheme adds experience in coastal flood defence earthworks and marine interface construction.
- Continued work on the Cydnerth tidal energy project in Holyhead builds capability in tidal infrastructure and marine geotechnics.
- 22% cumulative reduction in carbon energy performance since 2020 suggests systematic fuel, plant and logistics optimisation.
Our Take
The 22% carbon and energy performance reduction against a 2020 baseline puts Jones Bros towards the leading edge of the 2,383 sustainability‑tagged pieces we track, where many UK civils operators are still reporting only early‑stage baselining or single‑digit cuts.
Having simultaneous exposure to water storage (Havant Thicket Reservoir), renewables (Sanquhar II, North Kyle, Cydnerth) and coastal defence (Kinmel Bay) positions Jones Bros squarely in the UK’s climate‑adaptation and energy‑transition workload, which in our coverage tends to offer longer, more resilient order books than pure transport‑only contractors.
