But we are also aware there is always room for improvement so we take all customer feedback extremely seriously. After every installation we ask our customers to fill in a questionnaire for us. The questionnaire asks about first impressions, interaction with the company, product choice and quality, value for money and overall satisfaction.

98% of our customers were very happy and 2% were happy with our overall services and 100% of our customers stated that they would recommend us to family and friends

In 2015, 90% of our customers were very happy, 9% were happy and 1% were satisfied with our Overall services. 98% of our customers stated that they would recommend us to family and friends.
That’s a fantastic 8% increase in customers that are very happy with our services & 2% increase in customers who would recommend us to family and friends.
