About us

As a business development consultancy, we are passionate about helping our clients develop processes, skills and behaviours that will result in increased sales and improved margins.

Who we work with

Since 2011 Questas has been helping professional and engineering services firms grow. We have developed a deep understanding of the challenges faced by our clients operating in the built and natural environment.

The people Questas work with are generally technical experts who need to develop their client relationship and business development skills. They range from junior to senior, groups to individuals. One day we’re introducing BD concepts to graduates, the next we’re coaching senior directors and partners on specific client or market issues.

Questas Quote Marks CircleQuestas help us with our key account management programme and we have implemented their ‘toolkit’. We find the simple and effective approach works very well for us. In terms of the impact of the programme, we are becoming more proactive, finding more opportunities and working together in a more consistent and effective way.”

the questas difference

The training programmes we develop with our clients are designed to deliver long-term sustainable changes in the way their business grows. We don’t believe that a single training course without follow up and work-based practice works.

practical theory

Whilst we teach theory where necessary, our workshops and one-to-one sessions are highly practical and designed to be relevant to the audience so that they can use their new-found skills and ideas in the workplace straight away.
