Got this email from builder

Just received an email.
They have specified this boiler and controls to get the sap points. It's got no flue gas heat recovery, so surely I can just fit a vaillant as I quoted with weather compensation??

Here is the mail

Hi Paul
This is what they put in as long as it is equivalent it wont matter

Worcester Greenstar 30 si Compact


Heating controls have been entered as time and temperature control zone (Control code CBI).
Delayed start & boiler interlock added
Compensator
