Know when The Decommissioning Alliance's contracts come up for renewal

Business predicts when each of these contracts is due to be re-tendered, follows The Decommissioning Alliance for you, and alerts you the moment a renewal goes live, so you can bid before the incumbent locks it in again.

Why track The Decommissioning Alliance?

The Decommissioning Alliance is an active supplier to UK public sector buyers. Their contract history is one of the clearest guides to where the work is: which authorities they serve, what those contracts are worth, and, most usefully, when each contract is due to end. A contract nearing its end date is an opportunity, because the buyer will usually run the work again.

How renewal tracking works

We aggregate The Decommissioning Alliance's award notices from 600+ UK and Irish sources and read the end date on each contract. From those dates, Business predicts when each contract is likely to be re-tendered and, if you follow the supplier, alerts you the moment a matching tender goes live. That head start lets you speak to the buyer and prepare a bid before the incumbent is confirmed again.

What you can do here

  • Review the full history. Every contract The Decommissioning Alliance has won, with the buyer, value and dates for each.
  • Spot upcoming renewals. Contracts approaching their end date are the ones most likely to reopen.
  • Track and get alerted. Follow The Decommissioning Alliance and be notified when their contracts come up again (Business).
  • Benchmark and target. See which buyers rely on them and at what value, then focus where you can win.
