Crystal's Approved Installers - making selling easy!


Join the Crystal Approved Installer UK Network

Crystal are the authorised and approved supplier of PVC-U and aluminium windows, doors and conservatories to Builders Merchants across the UK. These include the vast majority of all independent merchants, as well as Blue Chip PLC’s like Buildbase and B&Q TradePoint.

Our Builders Merchant customers, can also require installation of our products, via our Crystal Approved Installer Network. The majority of installation companies spend a vast amount of their time converting leads to sales, which then need to be surveyed as ‘part of the job price’. Often, as competition is always an issue, companies have to take on work  further afield than they would like, increasing costs and further reducing profits. Even then assuming all goes well, installers very often have to wait for one reason or another to be paid – not anymore!

Crystal Approved Installers only receive pre-priced and sold jobs, so no time wasting and what’s more, Crystal Approved installers get paid for every survey! Installation works are paid 50% in advance and balance on completion of works – there are no retention payments, no JCT contracts or anything similar.

Crystal Approved installers choose which postcode area they want work in, so no more excessive traveling for work!  Interested in joining the Crystal Approved Installer UK Network?  Call us on 01462 489900 or email
