Description
The Framework Agreement will operate on a multi-supplier basis. Yorkshire Water will award call-off contracts in accordance with the Framework Agreement and the procedure applicable to the relevant Lot and requirement.

RISKS AND UNKNOWNS
Points requiring attention
Value inconsistency
100% confidence
The stated framework maximum value (£14,250,000) does not equal the sum of the four stated lot values (£12,934,000), a difference of £1,316,000. The supplied data does not explain the difference.
View supporting evidence
Process value_max is 14250000 GBP; lot values are 8600000, 810000, 2440000 and 1084000 GBP.
Publication-date inconsistency
100% confidence
The process published date (26 August 2026) predates the supplied tender-notice document publication date (13 October 2026). The supplied data does not explain whether these represent different notice events.
No submission deadline is supplied at process or lot level despite the opportunity being marked open.
View supporting evidence
