Partnering with Businesses to Achieve Sustainable Growth.
About Green Platypus.
Built by Veterans. Backed by Experience.

We now help organisations of every size reduce costs, streamline operations, and meet their sustainability goals.
We’re proud to donate 10% of profits to UK charities, employ veterans wherever possible, and reinvest in the communities that supported us.
