PES Practice Invoice and Payment Timescales


This article provides information on the timescales associated with invoices and payments for services commissioned via Primary Eyecare Services (PES).


Activity completed by your practice for a particular service in a month will be compiled and an invoice generated in the second week after month-end. With the overarching invoice from Primary Eyecare Services (PES) and associated supporting data submitted to commissioners thereafter along with associated backing data that commissioners ask for. 

This process requires no action by practices as is carried out by PES with the support of Opera and other associated systems. 


You must close/complete (and appear marked Green on Opera) an episode in order for it to be charged. If you need to close an open episode you can follow the instructional guide linked here to enable you to do so. If you need support when closing a patient episode, please contact us for support via the help function on Opera.

Please remember that episodes should be completed and closed on Opera ideally on the same day of the patient interaction took place (as a minimum for those being referred) but within 2 working days as a standard minimum. This is important for patient safety, communications with GP, contractual requirements, etc. - including invoicing and payment!      

Raising issues with your invoices

All queries should be raised via the blue bubble on Opera or emailing We expect there will be very few of these. Where adjustments are required these will be made to your next month's invoices for that commissioner.  

Please provide your practice name, ODS code, and OPR numbers for episodes that you need assistance with.


The commissioner invoice is due for payment to PES 30 days after submission (approximately 6weeks after month-end) and disbursement to practices will take place within 7-10 working days to optical practices after PES has received the monies. This will be paid to the bank account you uploaded details for onto Opera as part of the onboarding process. 


An invoice becomes overdue for payment to PES approximately 6 weeks after month-end and to practices 8 weeks after month-end.

It is expected that regular monthly payments should be made to practices albeit they will be for 1-2 months in arrears due to the above process with NHS commissioners. (current timescales may be longer). 

Inevitably there will be cases where some are delayed payments from commissioners and thus the above process is delayed and extended. Please note there are often some delays in the early stages of a new service prior to the regularisation of payments.  

In all cases, PES will actively chase commissioners for overdue monies and pay practices as promptly as possible.   

[Please Note: As per the subcontract that practices have with PES - payments can only be made to practices after PES has received monies from NHS commissioners. PES does not retain large reserves as it supports the sector by maximising fees paid to practices and as such we are dependent on timely payment from commissioners to ensure timely payment to practices]
