FENSA, a government-authorised scheme, plays a vital role in ensuring building

regulation compliance for replacement windows and doors in the UK. As a reputable

accreditation body, FENSA monitors and assesses each FENSA Approved Installer,

irrespective of size, from large national brands to small local companies, on a regular

basis.

This diligent assessment process ensures that all FENSA Approved Installers,

including TF Energy, consistently adhere to building regulations, delivering high-

quality and compliant installations for windows and doors.
