Contract Overview
Yorkshire Water Services Limited has published a competitive tender for the renewal of water mains across the Sheffield area. The contract covers 39,818 metres of pipeline — a significant urban programme — with a total contract value of £17.2 million.
This is structured as a sole award: one contractor wins the entire programme with no lot splitting. The contract runs for one year from 1 April 2027 to 31 March 2028, with the procurement procedure running over a six-month competitive flexible timeline.
Supply chain angle: With 39,818m of mains to renew across a major urban centre and a fixed-price lump sum structure, this contract rewards contractors with strong Sheffield regional presence, established supply chains for pipe materials, and the cost certainty to price NEC Option A competitively. At £17.2m for a single winner, it is a meaningful standalone programme for a mains renewal specialist.

Why This Contract Matters
Mains renewal remains one of the highest-volume contract types in the Yorkshire Water AMP8 programme. At £17.2m for a single Sheffield programme, this sits comfortably in the range where regional civils specialists, utilities contractors, and pipe-lining firms compete directly — it is large enough to be meaningful but structured as a single award rather than a framework, which concentrates risk and reward.
The 70/30 price-quality weighting means cost competitiveness is the primary driver, but the 30% quality score gives firms with strong delivery track records and local supply chain arrangements a meaningful edge over those competing on price alone.
The NEC Option A (Fixed Price Lump Sum) structure means the winning contractor bears the risk of cost overruns — pricing discipline and site familiarity in the Sheffield area will be critical to margin.
