As from 1st October 2015 all qualifying new Windows and Doors installed into new Dwellings will be required to meet PAS 24:2012 or other standards that exceed or meet this standard.
Compliance is the responsibility of the installer so we must be informed of any windows or doors that fall under these new requirements to ensure that the correct system, glass and hardware is used. Upgrading to PAS 24:2012 may affect your quote.
