A Company To Trust - Mitchell Glass Has Multiple Accreditations

You’d never invite just anyone into your home, so why would you appoint just any old home improvement company to fit it with new windows? Hopefully, you wouldn’t.

It needs to be a team you can trust, but how can you establish whether a window or door specialist is trustworthy?

Checking out online reviews is a good starting point and also speaking to any family members or friends to gain their thoughts on who they would suggest you use can help too. 

Uncovering if the window and door businesses in your area have any recognised and recognisable industry accreditations is also a good way of separating the best from the rest. 

Mitchell Glass is an acknowledged member of FENSA, the GGF and TrustMark – you shouldn’t expect anything less from a company with 145 years’ experience. 

We’ll explain the significance of these high-profile accreditations.


Created by the Glass and Glazing Federation in 2002, the Fenestration Self-Assessment Scheme is the foremost Competent Person Scheme for the window and door installation industry in England and Wales. 

They have recently run a TV campaign, which if you’ve seen, tells you that choosing a FENSA member ensures you of a replacement window or door installation that complies with building regulations. 

This compliance is essential. Without it, you could experience difficulty trying to sell your home. 


Dating back to 1977, the GGF seeks to raise industry standards and promotes excellence amongst its approved members. 

Earning GGF membership certainly isn’t easy. You have to prove to their assessors that your products and services are exceptionally good to receive their endorsement. 

After securing member status, you must abide by the GGF’s Code of Good Practice. If you’re found to be falling short of the expected standard, you can be stripped of your membership. 


A Government backed scheme, formed in 2005, TrustMark aims to protect people who have work done by a TrustMark Registered Business at their home. 

As with the GGF, they stringently vet all organisations who hope to receive acceptance onto the scheme and expect nothing but good customer service, technical competence and exemplary trading practices from them.

It’s firmly in the interests of a consumer to use a TrustMark member, particularly as they offer a resolution service in the event of an unsatisfactory installation.


We love what we do and these three endorsements prove the unrelenting commitment we have to our customers. We don’t even expect you to call us – arrange a callback and we will call you.
