WRAS have updated the F2 application form.
CHANGE 1:
Appendix D has been added and includes check boxes to identify if the application is submitted via a laboratory or if it is submitted directly to WRAS. WRAS require the section to be completed in full for all applications submitted directly to WRAS.
CHANGE 2:
Section H has also been updated to include a column that requires applicants to name the inlet and outlet connection sizes of each model.
The guidance document has been updated to cover these changes.
The F2 and the guidance form can both be downloaded from here
