The Port of Dover and Eurostar have both said they are ready for the phased start.
At Dover, coach passengers will start using the new system on 12 October, followed by other tourist traffic on 1 November.
At Eurostar, a small number of business travellers will be invited to use the new system from October.
Eurostar has installed 49 EES kiosks in three areas around its London St Pancras terminal.
In the six months before full implementation, all operators will be able to ask for checks to be suspended to allow French border control officers to revert to the manual stamping of passports.
The UK government recently launched a publicity campaign to alert passengers to the incoming changes.
