Preliminary Market Engagement for Thermal Improvement Works
Framework ceiling £30,000,000 — the most the agreement may spend across all suppliers and call-offs, not a contract value
Trivallis has published 3 Construction Materials & Structures notices, about every 29 months. On that rhythm the next one is expected around September 2028.
30% of Trivallis’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 →
