Published requirement description

This Heating and Water Repairs and Maintenance Services contracts procurement is segregated into (5) lots:

Lot 1 Individual Heating

Lot 2 Communal Heating

Lot 3 Water Hygiene

Lot 4 Building Energy Management Systems (BEMS)

Lot 5 Temporary Boilers

Lot 1, Lot 2 and Lot 3 are further segregated into two geographic areas and therefore two contracts. For these Lots, Suppliers will be required to submit only one bid but will be automatically eligible for award in either of the two regions and are therefore not required to indicate a preferred region.

  • The authority expects to re-tender this requirement around 30 Apr 2036, 23:59 BST.
  • How the procedure runs: This is a two stage procedure comprising a Selection Phase containing Procurement Specific Questionnaire (PSQ) documentation followed by a Tender Phase evaluating Quality and Price. Following assessment of responses to the PSQ, a short list of the top five highest scoring potential suppliers will be drawn up per lot. The shortlisted suppliers will be selected to participate in the Invitation to Tender (ITT) phase. Suppliers are therefore only to complete the PSQ Stage documentation by the set deadline.
