Summary of the contracting process

Natural Resources Wales is currently in the tender update stage for their Diving Services Open Framework 2026. The framework aims to support scientific divers in monitoring subtidal reef features under the Habitats Directive within Welsh Special Areas of Conservation (SACs). The framework agreement, involving a budget of £700,000, will be divided into three phases over eight years, reopening in 2029 and 2032. The process follows an open procedure, and businesses can express interest via the eTendering portal by the deadline of 10 April 2026. The project, based primarily in Wales, spans multiple marine locations and involves a comprehensive range of diving services within the UKL region.

This tender presents notable opportunities for businesses specialising in marine diving services, particularly those with expertise in scientific diving and marine ecology. Small and medium-sized enterprises (SMEs) with experience in taxonomic identification, diving supervision, and various marine surveying techniques are well-suited to apply. The framework includes the provision of specific roles such as Sponge Taxonomist and Survey Coordinator, enabling businesses to broaden their capabilities. Furthermore, the long-term nature of this framework allows companies to build partnerships and strengthen their market presence within the ecological monitoring sector. With high weightage given to technical quality over price, firms focused on delivering high standards and innovative methodologies may find this tender advantageous for growth.
