Wylfa

Posted: 23rd August 2026

Great British Energy – Nuclear (GBE-N) has outlined plans for an early works package with an estimated contract value range of £730M to £1.1bn. A preliminary market engagement notice published on 20 August sets out the scope of the package, which covers civils, infrastructure, buildings and MEP, and earthworks. The package covers key enabling activities required to prepare the (unlisted) site for main construction. The early works package forms part of GBE-N’s Owner’s Scope, which encompasses the planning, licensing, design and construction activities necessary to enable a Technology Partner to install and commission small modular reactor (SMR) technology. SMR is a category of nuclear fission reactors that are significantly smaller in size and power output than traditional gigawatt-scale nuclear plants. GBE-N has spearheaded a competition to select preferred technologies, naming Rolls-Royce SMR as a preferred designer for projects at sites like Wylfa in North Wales (main image above). The estimated contract period is from 1 June 2028 to 1 June 2034, with a possible extension to 1 June 2037 and the work includes design from RIBA Stage 4 and delivery of ground-related enabling activities, including species relocation, remediation services, site clearance, site establishment and construction utilities.
