Low‑Carbon Concrete Becomes Standard: Driving Net‑Zero in UK Construction

Welcome to Net Zero News, your daily briefing on the UK’s transition to a low‑carbon future.

The construction industry is making significant strides in reducing its carbon footprint, as evidenced by a growing number of net‑zero and low‑carbon commitments across projects. A notable development emerged in December 2025 when Laing O’Rourke mandated the exclusive use of low‑carbon concrete on all new UK projects starting from April 1, 2023, aimed at accelerating its progress towards net‑zero targets and helping clients meet sustainability goals. This initiative signals a meaningful shift toward decarbonising embodied carbon in construction materials and could set a new industry standard.

Meanwhile, refurbishment projects are also transforming the built environment. In Birmingham, Willmott Dixon Interiors completed a 139,000 sq ft back‑to‑frame office redevelopment in city centre that meets net‑zero carbon standards across seven floors. The office space is BREEAM Excellent, EPC A rated, aims for a top-tier NABERS target rating, and is pursuing WELL Gold certification representing a holistic approach to sustainable retrofit that also focuses on occupant wellbeing. The project generated social value by directing significant spend to local suppliers and creating job, training and apprenticeship opportunities.

Education buildings are increasingly becoming exemplars of net‑zero design. In Wales, Willmott Dixon secured a contract to build a new primary school serving Cefn and Craig yr Hesg, aiming to deliver Passivhaus certification, Building With Nature accreditation, and WELL Building Standard recognition. The development will incorporate rain gardens and nature‑based surface water management, emphasising both environmental performance and community health.

Scotland is also embracing low‑energy school construction. In Edinburgh, the Currie Community High School is set to open in early 2025 and will be the first secondary school in the city built to Passivhaus standards. The school’s design incorporates Armatherm 500 thermal breaks and other products to eliminate thermal bridging, substantially reducing energy loss. This supports the Scottish Government’s broader push for building standards equivalent to Passivhaus in new construction.

In strategic project planning, the West Midlands is witnessing the early stages of a net‑zero aligned logistics hub. Construction has begun on a new depot for Carlsberg Britvic, designed for energy efficiency and targeting BREEAM Excellent certification. The building is aligned with the pilot UK Net Zero Carbon Building Standard and will feature PV‑optimised roofing a forward‑thinking approach to low‑carbon infrastructure in the logistics sector.

Looking ahead, Oxfordshire County Council has embarked on a sustainable housing transformation by commissioning Willmott Dixon to create a ‘net‑zero in operation’ headquarters at Speedwell House. The redeveloped office is slated for completion following design finalisation in 2025, supporting both public sector decarbonisation and urban regeneration objectives.

Taken together, these projects illustrate a UK construction landscape increasingly shaped by low‑carbon materials, energy‑efficient design, retrofit excellence, and integration of nature into building fabric. The commitment to low‑carbon concrete, Passivhaus standards, smart certifications and nature‑rich features signals a pivotal era of sustainable building practice.

What this means:
This wave of innovation demonstrates the sector’s readiness to mainstream net‑zero principles from material selection to operational performance and occupant health. Low‑carbon concrete offers a path to reducing embodied emissions, while retrofit and new‑build projects with rigorous sustainability metrics highlight a growing demand for performance‑led delivery. Schools, offices and logistics facilities acting as exemplars will pave the way for wider adoption and help align the built environment with the UK’s net‑zero targets.
