Meet the inspiration behind your Quantity Surveying, Commercial and Contracts Team
We are people!
When Simon laid the foundations of ERConsult in 2012, the mission was simple: make expert quantity surveying, contract administration, and dispute resolution accessible to businesses of all sizes—not just those able to absorb the cost of full-time hires.
Having seen firsthand the positive impact these skills can have, Simon built ERConsult on a different approach—commercially collaborative, technically sharp, and focused on outcomes, not conflict. That principle still drives everything we do today.
Win Better Work
Review contracts before you sign so risk is understood , pushed back on and priced properly.
Protect Your Margins
Strengthen notices, variations, applications, and records before value slips out of the job.
Specialist Resource
Access senior commercial support when you need it, without the cost and commitment of a full-time hire.

Contracts don't have to become a dispute
Our Playbook
ER supports SMEs in all things contracts.
We are not aggressive, and we do not believe in “contract avoidance.” Our approach is simple: clear advice, strong communication, and complete commercial understanding.
We focus on one thing — protecting and delivering your margin. That means being honest about where projects are working, and where they are not.
That is what drives protected growth.
Our model is built on a deep understanding of how contracts succeed and fail, giving our clients access to specialist commercial support they would not typically have.
Focus it
Depth over distraction — contracts, margin, commercial control.
Say it
We say what others won’t — clear advice, straight answers, no noise
Own it
We stand with our clients — accountable, proactive, outcome-driven.
