In brief

Thames Water Utilities Limited has announced plans to buy construction and building maintenance work. This is an early notice: there is nothing to bid on yet, but it tells you a tender may follow.

It is a framework worth up to £175,040,000 including VAT: the most the buyer expects to spend across all suppliers, not one contract.

The contract runs for 5 years, up to 8 years with extensions, starting 1 April 2026.

It is split into 7 lots, so a supplier can bid for part of the work.

Built from the notice's own fields. Always check the official notice before you bid.

Competition

Typical: a median of 5 bids per contract for construction contracts in this region (from 423 awards in the last 12 months).

Framework

Winning puts you on a list of suppliers the buyer can call on; it does not guarantee work. The £175,040,000 is the most the buyer expects to spend across all suppliers over the framework's life, not one contract.

The buyer expects to buy this again around April 2033.
