Order by the date shown and there is time to do it well. The dates count back UK working days from the deadline to take part (England and Wales bank holidays left out). Paid in full before work starts; a full refund if you cancel before kick-off, the working day after you pay. No win guarantee and no success fee.

This deadline is for the first stage, the request to take part. A Lite pack covers a selection questionnaire; the full tender comes later, for the suppliers invited.

One pack covers one submission. Separate answers for several lots may need a larger pack; you are told before kick-off and can have a full refund.

The order page sets out the full timeline, what you supply and the terms. I confirm within one UK working day that I can take this tender, and if I cannot, you get a full refund. If I miss a delivery date for a reason in my control, and your inputs arrived on time, you choose a full refund or late delivery.
