When do you need a FENSA certificate?

We often get asked by our customers if we can supply a FENSA certificate when installing our roof light products as there seems to be confusion over what FENSA actually is and how it is applied to works being carried out in your home. Even a cursory glance at the FENSA website states that FENSA is a government authorised Competent Persons Scheme for the replacement of windows, doors and roof lights in England and Wales. This post will aim to clear up any confusion and enable those purchasing a glass rooflight to understand when a FENSA certificate is required. So let’s start with what a FENSA actually is… FENSA stands for the ‘Fenestration Self-Assessment scheme’ which has been set up by the Glass and Glazing Federation (GGF) as a means to self-certify compliance under Building Regulations without the need for a separate assessment from Building Control. If your installer is not registered with FENSA any works that include replacing windows, doors and roof lights will require you to get a certificate from Local Authority Building Control instead. When does FENSA apply to glass rooflights? FENSA certification can only apply if you are replacing an existing skylight window; installation of a new skylight will require certification from Building Control to ensure that any structural changes and thermal performance meet current regulations. FENSA does not apply to conservatories, porches, commercial premises, new build properties or extensions. In all of these instances you are required to go through the Local Authority Building Control process. Summary If the rooflight is a new addition to your property, or the building itself forms part of an extension or is a complete new build, then FENSA does not apply and you will require approval from Building Control. If you are replacing an existing rooflight, you can use a FENSA approved installer or alternatively apply for full Local Authority Building Control approval. Please note that the homeowner is ultimately responsible for ensuring that their rooflight installation complies with these standards and regulations.
