Customers recommend Ecostar’s world class product and service


At Ecostar, customer satisfaction is the cornerstone of our business.

A great deal of our new business is driven by recommendations from our valued Ecostar customers, and we implemented our ‘anchor client’ program and referral bonus scheme to reward them for their loyalty.

We invest heavily in maintaining our reputation for world-class double glazing products and service, employing highly-trained surveyors and in-house installation teams (rather than external contractors) who treat your home as if it was their own during the double glazing installation process, and offering an industry-leading unconditional 10 year guarantee.

So, we were delighted to receive affirmation of our commitment to customer service in a survey* of nearly 200 customers who have purchased uPVC double glazed windows and doors from Ecostar Double Glazing over the past 12 months.

When surveyed, 93% of our customers told us they would “definitely” recommend Ecostar to friends, family and colleagues looking to upgrade their homes with new windows and doors. Meanwhile, eight out of 10 of our customers rated their Ecostar uPVC double glazing installation experience ‘very good’ – the highest possible rating in our survey.

At Ecostar Double Glazing we’re proud of the customer relationships we’ve built over 40 years of installing European high-specification uPVC double glazing, and we’re constantly looking for ways to enhance our product range and service. Stay tuned on our website an social media for some exciting initiatives coming in 2019.
