Ideal Glass is FENSA registered

A FENSA certificate isn’t just a nice-to-have, it’s a need-to-have. Because the certification means you’re working with a professional company that will meet two legal requirements and provide you with an important level of protection. Most people haven’t the time, knowledge or inclination to check these three things themselves. So, what are they?

A FENSA certificate is your assurance that the installer who fitted your windows or doors has complied with Building Regulations. It also means that your installation(s) will have been registered with the Local Council. These are legal requirements and proof of them is essential when selling your home.

In addition, FENSA certificates issued after 6 June, 2014 verify that the installer’s warranty is insured. Reassuring to know if anything goes wrong, and the business gets into trouble.

So remember: you’re not just asking for a FENSA certificate. You’re asking if that window or door installer you’re thinking about using is professional, will comply with Building Regs, register your installation, and offer an insured warranty.

That’s why we say the FENSA certificate is all the proof you need of a job done right.
