Before You Decide
Is FENSA Registration Important?
Yes. FENSA registration means your installation is self-certified for building regulations compliance. Without it, you'd need separate building control approval which costs extra and takes longer.
Will Compliance Add to the Cost?
No. All our products meet relevant standards as standard. Compliance isn't an add-on — it's built into everything we supply and install.
What Documentation Will I Receive?
FENSA certificate, manufacturer warranties, and relevant test certificates (PAS 24, Part L compliance, Secured by Design where applicable).
Do I Really Need Certified Products?
For new builds and replacement windows/doors, building regulations require specific thermal and security standards. FENSA-registered installation is also legally required unless you go through building control separately.
