UK7 - Contract Details Notice
Summary of the contracting process

The National Oceanography Centre procured replacement mechanical plant and associated building services works for its Energy Centre in Southampton. The scope covered removal, supply, installation, testing and commissioning of three critical assets: a low-temperature hot-water deaerator, a chilled-water-system pressurisation unit with expansion vessel, and a seawater boll filter. The purpose is to maintain reliable, efficient and resilient heating, cooling and seawater systems after existing equipment reached or approached the end of its economic and operational life. The contractor also had to complete the mechanical, electrical and controls integration needed to make the replacement plant fully operational. This is a works requirement involving heating-plant maintenance, repair and purification-plant equipment.

The procurement is complete and the contract was awarded to MKG Building Services Ltd through a below-threshold limited competition. The contract was signed on 17 September 2026, with delivery scheduled from 12 October 2026 to 6 November 2026. Its value is £38,390.89 excluding VAT and £46,069.07 including VAT. One completed lot covered the full requirement. The award is active and the contract is active. The works were evaluated through the limited competition route; the published information does not set out a separate weighting or scoring basis. The buying organisation is the National Oceanography Centre, and the contract covers plant replacement and integration at its Southampton site.

This requirement indicates demand for specialist building-services contractors able to manage plant replacement in a live or operational energy-centre environment. A credible competitor would need practical expertise in low-temperature hot-water systems, chilled-water pressurisation and expansion vessels, seawater filtration, and the associated mechanical, electrical and building-controls interfaces. The work also calls for end-to-end delivery: removal of obsolete equipment, supply of replacement assets, installation, testing, commissioning and handover of a functioning integrated system. Contractors with experience maintaining heating, cooling and seawater infrastructure, coordinating multiple engineering disciplines, and demonstrating reliable delivery of technically sensitive works would be well placed when comparable requirements from this buyer return to market. The awarded supplier was an SME, indicating a scale accessible to capable smaller building-services businesses.
