We have experience of this. We have a separate process for discharging conditions, as do most authorities. They can therefore apply to have each condition discharged individually, or in bulk. They then have a decision notice from the council that confirms full or partial compliance (for example landscape details to be submitted and then implemented can only be fully discharged once implemented).
I am aware that some councils take the fee but add the paperwork to the original application. For various reasons, we decided that a discharge of condition application was a separate entry in our computer system and as such gets its own number and decision notice. This allows us to monitor progress and ensure none are lost.
If the RP wants a "certificate" to prove discharge of conditions... get them to submit a discon for all the conditions and then process.
If they want a certificate to say it was done by certain dates to show pre-commencement, that I would say is a certificate of lawfulness. Be careful not to re-invent the wheel, because you may inadvertently provide a document which purports to be a letter of comfort, but is construed as a certificate of lawfulness. Get them to submit dates and evidence and give them the certificate which they can rely on...
