Timber - PVC - Aluminium - Windows, Doors & Conservatories in Dorset



FENSA was set up by the Glass and Glazing Federation (GGF) at the request of the the Department for Communities and Local Government (DCLG)  to allow registered companies to self-certify that their installations comply with current Building Regulations. FENSA does not apply to commercial premises or New Build properties. In both of these instances you are required to go through the Local Authority Building Control process. FENSA Registration is also not applicable to the Installation of Conservatories or Porches by a FENSA Registered Business. This also means that if you had windows and door installed as an extension that required building regulations, the installation will have been covered under the Building Regulation notice for that project.

If you are selling a property that has had replacement windows or doors (with less than 50% glass) installed since July 2002, you will need to provide the purchaser with a FENSA certificate. Not having this important document can hold up the sale of the property, so do please make sure that if you have had (or are planning to have) any replacement windows or doors installed in your home that you receive a FENSA certificate within 6-8 weeks after the work is carried out. You can check online at www.fensa.org.uk that your installer did register the work they carried out on your property with FENSA.
