About us

We have decades of environment and engineering experience.

Our Story

GDP was formed in 2015 by Gareth Pickles who after over 20 years in corporate life decided to move away from growing a ‘more of the same’ business and create something much more engaging. Gareth was joined by Jay Fox in 2016 as co-owner and director. Jay also has over 20 years in industry including some of the worlds largest consultancy groups.

Our offer is to work as part of the client team with like minded friendly people across the real estate sector to deliver tangible value and enhanced profitability on every scheme. Having advised on many thousands of sites in the most technically and commercially challenging circumstances we can often see commercial opportunity where others see risk and cost.

Located centrally in the UK near Newark on Trent in the East Midlands, GDP works throughout the country supporting board level decision making through to practical project implementation, whatever the size of the scheme.

  • "GDP's attention to detail throughout the process was second to none and kept us fully appraised during monitoring. GDP provided Mayberry with a full comprehensive report which in turn allowed for the planners to be able to clear the conditions within a matter of days with no subsequent detail being required. A truly professional service from start to finish and we at Mayberry look forward to working with GDP on future projects."
