When the tender is published

  • Register on the buyer's e-tendering portal and download every document.
  • Confirm your Central Digital Platform registration and supplier information are current.
  • Record the submission deadline, clarification deadline and any site visit dates.
  • Build a compliance matrix: every requirement, question, word limit, format and attachment.
  • Make a documented bid/no-bid decision.

Planning

  • Assign an owner for every question and attachment.
  • Agree win themes and the evidence you will use.
  • Plan internal deadlines: first drafts, review, pricing sign-off and final sign-off, with upload at least 24 hours early.
  • Submit clarification questions before the clarification deadline.

Writing

  • Answer every sub-question in the order asked.
  • Follow the scoring descriptors for the top mark.
  • Evidence every claim with data, case studies or named processes.
  • Respect every word, character and page limit and the formatting rules.
  • Keep commitments consistent across quality answers and pricing.

Documents

  • Policies signed, dated within 12 months and in the right company name.
  • Insurance certificates at the required levels, or confirmation you will obtain them by award.
  • Accreditations and certificates in date.
  • Case studies and referee details confirmed.
  • Pricing schedule complete, with no altered formulas and no blank cells.
  • Declarations, forms of tender and any Carbon Reduction Plan signed.

Before upload

  • Independent review against the scoring scheme.
  • Proofread names, numbers and buyer references; remove other buyers' names.
  • Check file names, formats and size limits.
  • Upload early, confirm every section shows as complete, and save the submission receipt.

Frequently asked questions

How early should we submit?

Aim to upload at least 24 hours before the deadline. Portals can be slow near the deadline and late submissions are usually rejected.
