This sits in the lower-middle of the Engineering & Architecture band — a mid-scale opportunity. Based on 33,646 valued Engineering & Architecture tenders in our corpus.
Trinity House has published 13 Engineering & Architecture notices, about every 3 months. On that rhythm the next one is expected around November 2026.
41% of Trinity House’s awards go to a supplier it has used before.
Which is the argument for getting on the list rather than winning this one. The incumbent is rarely the last winner — it is the roster. See the retention odds by category →
Trinity House (TH) holds the operation and maintenance responsibility for over 60 lighthouses around England, Wales, the Channel Islands and Gibraltar.
These critical aids-to-navigation (AtoNs) include several Rock Tower lighthouses that require regular modernisation and ongoing maintenance.
Accordingly, Trinity House would like to investigate the feasibility of utilising jack-up and floating assets to avoid repeated journeys to these remote locations by helicopter to mobilise personnel, equipment and tools.
To support this investigation, it is important to have accurate bathymetric and topographic surveys of the surrounding area.
