Tarmac has teamed up with Associated British Ports (ABP) and Brett to form a logistics partnership supplying construction materials to the Sizewell C nuclear power station project via the Port of Ipswich.

The partnership will use ABP’s West Bank terminal to provide a single logistics operation combining sea, rail and road distribution for aggregates and other construction materials destined for the Suffolk site.

The arrangement is designed to support Sizewell C’s target of transporting at least 60% of construction materials by rail or sea rather than by road.

Tarmac will supply construction materials and provide technical support, drawing on its experience of supplying major infrastructure projects and the nuclear sector.

ABP will manage port operations, including vessel handling, discharge and storage, while Brett will use its existing aggregates operation at the Port of Ipswich to receive imported materials.

According to the partners, the existing infrastructure at Ipswich has capacity for vessel movements, rail operations, bulk storage and onward distribution to the Sizewell C site.

The companies said the partnership would build on existing operations in Suffolk rather than requiring new logistics infrastructure.

Will Pearson, Tarmac nuclear commercial director, said: “Our focus is on ensuring consistency and certainty in supply as the project progresses.

“By combining our materials expertise with established rail capability, we can help maintain momentum on site while supporting more efficient, lower-impact delivery at scale.”

Paul Ager, ABP divisional port manager, said: “We believe this partnership gives Sizewell C a practical solution with strong marine and rail capacity at its core.

“Ipswich gives the scale, the storage capacity, quayside strength to support large volumes and the connectivity needed for reliable delivery.

“This is a solution that works with the local community and reduces pressure on local roads.”

Oliver Brown, Brett development director, said: “The Brett site in Ipswich has been operating since the 1980s and this partnership builds on that local strength.

“Our site at the West Bank is already a key part of the region’s aggregate supply and our ability to import aggregates by vessel and links to the rail network give us a strong base for supporting Sizewell C.

“This collaboration supports reliable delivery, efficient movement of material and lower impact on the environment.”
