The North Yorkshire-based supplier has also been expanding, with its headcount now at 77 employees, 31 of which are in sales. It aims to reach a £20m turnover by the end of the decade.
The results come as Green-tech marks two years at its purpose-built premises, Rabbit Hill Park, just of the A1 in North Yorkshire. The head office, warehouse and distribution premises, which the company invested more than £3 million in are home to Green-tech’s head office, warehouse and distribution facility and customer collection store.
Earlier this year Green-tech bought Flexible Lining Products (FLP), the specialist online distributor of Terram, pond and lake liners, erosion control products and porous paving systems.
Chairman Richard Kay said: "It has been a tremendous year for Green-tech, I am delighted that our hard work and commitment to the industry and our clients has paid off and we have increased our turnover by 23% from 2016. We are aiming to reach £20 million turnover milestone so you can expect more acquisitions and new product development from Green-tech."
Green-tech is the headline sponsor of the BALI National Landscape Awards. The company is also a winner in this year’s awards in the ‘Affiliate Exceptional Service category.
