If you have 've replaced windows and/or doors in multiple flats within one building, you will need to register each individual flat so they get a FENSA Certificate of their own.
When you register an installation select the Bulk Upload option in the FENSA Installer Portal. Here you will find templates for you to use and a guide that will help you understand how to use the template.
TIP - If this type of installation was for a Housing Association or Local Council, check that you have the correct "Installer Type" noted with us.
See here for the different Installer Types
Contact us if you feel we need to make a change on your record.
NOTE: YOU CANNOT REGISTER THESE INSTALLATIONS IF THE BUILDING YOU INSTALLED IN IS MORE THAN 18mtrs IN HEIGHT. (this is still the case even if you installed only on the ground floor)
