Do I have to spend the whole eCertificate amount?
You do not have to spend the full value of your eCertificate but this is not advised as your overall package price and monthly Hire Agreement costs will not be reduced if you underspend.
Cyclescheme recommends that all participants redeem the full value of their eCertificates at the point of redemption, as it's essentially a 'use it or lose it' scenario.
If you feel that you've requested the wrong amount and would like to request a lower amount, you will need to request to cancel your request with your employer and reapply. This can be administratively clunky and take a little time, so do consider this before pursuing a cancellation to lower the price of your package. You may just want to retain your current eCertificate and use the additional funds to get accessories.
