As a Sheffield-based firm, we’re proud to work with engineers and manufacturers

“I engaged Knowles Warwick in February 2017 to provide financial and commercial due diligence for my acquisition of a group of engineering companies with a transaction value of £1.1M. Knowles Warwick demonstrated their local experience, were easy to work with and communicated very well. They have provided a comprehensive report that allowed me to recognise potential liabilities and resulted in a renegotiated deal in my favour.”
