Which double glazing trader should you choose?

To assist householders and give them greater peace of mind when appointing an installation company, consumer champions Which? established an endorsement scheme labelled ‘Which? Trusted Traders’.

Back in 2014 the region’s largest independent double glazing manufacturers and installers, Hazlemere Window Company, joined this prestigious scheme after they passed an intense assessment process, proving that they met the strict requirements set out by Which? and satisfy the high standards they expect of a local and reliable trader.

To be recognised in this way is an extremely prestigious achievement’ for any supplier, particularly as 25% of traders fail during the assessment stage.

It demonstrates to customers that those who achieve Which Trusted Trader status have proven themselves as having been trustworthy up to that point, and that they are firmly committed to offering complete fairness and transparency at all times. Having such status enables us to display the Which? Trusted Traders logo on all marketing materials which will give customers added confidence when choosing a double glazing supplier ahead of any other local installation company.
