FENSA (Fenestration Self-Assessment Scheme) is a government-authorised scheme that monitors building regulation compliance for replacement windows and doors. The scheme is designed to ensure that all new installations are energy efficient, secure, and comply with current UK building regulations. FENSA is the most well-known competent person scheme in the UK and is integral in the double glazing industry, providing standardized guidelines that installers must follow.

Significance of FENSA Accreditation

FENSA Accreditation for ETC Windows indicates a benchmark of excellence and compliance in the installation of windows, doors, and glazed extensions. This accreditation involves several key aspects:

  • Regulatory Compliance: ETC Windows is regularly assessed to ensure that their installation work complies with building regulations, which is crucial for both safety and performance standards.
  • High Standards: To maintain FENSA accreditation, ETC Windows must consistently demonstrate adherence to strict standards in installation techniques and product quality.
  • Professional Certification: Every installation by ETC Windows that falls under the FENSA remit comes with a certificate, which homeowners can use as evidence of compliance should they choose to sell their home.
