Postcode Lead times is available on your My availability page. This feature will enable you to select specific Postcodes where you can pickup at short notice, regardless of your account's overall notice period.
So for example, you may want to cover all postcodes within 3 miles of your office within a 30 minute notice. This setting is ideally for areas where you have drivers stationed. You can be as flexible as you like - adding and removing these postcodes as and when you need to do so.
Please note that pickups in those postcode areas where Postcode Lead times are applied will override your account's notice period which is active for all other pickups.
