There are two options when it comes to installation. You could use a Quickslide stockist registered with a competent person scheme such as Fensa or Certass who will be approved to carry out the work to comply with building regulations. Once the installation is completed they will be able to issue a certificate to prove that the work was done by a registered installer. Alternatively, you have the option of sourcing your own builder or even do the installation yourself, in which case approval can be sought from the relevant body – either your local authority or an approved inspector who will check the replacement windows and doors for compliance.
A FENSA certificate does not relate to the manufacture of the products and it is therefore not something Quickslide can issue.
