At SGF Consulting, we specialise in helping construction and infrastructure subcontractors protect their position, improve profitability, and manage commercial obligations with confidence.

With over a decade of experience working for Tier 1 main contractors, including major projects under NEC and JCT contracts, we know exactly what main contractors look for — and where subcontractors often lose time and money.

That insight gives our clients a clear advantage: we help you anticipate issues before they become problems, present your commercial case effectively, and ensure you’re paid fairly for every element of your work.

Understanding Both Sides of the Contract

Founded by Stacy Deeley-Carter, a Senior Quantity Surveyor with experience working for Tier 1 contractors, SGF Consulting understands the pressures subcontractors face.

From chasing payments to managing variations and dealing with complex contract terms, subcontractors are often expected to perform commercial duties without having the time or in-house expertise to handle them properly.

That’s where SGF Consulting comes in — providing flexible, practical commercial support designed to protect your business and improve your bottom line.

Our Services for Subcontractors

1. Tendering & Pre-Contract Review

We help you review tender documents and proposed contracts to identify risks, omissions, and unfair clauses before you sign. Our goal is to protect your margins from day one and ensure you fully understand your contractual obligations.

2. Measurement & Take-Offs

We provide accurate measurement and take-off services from drawings to help you price projects correctly, avoid underestimation, and submit competitive but realistic quotations.

3. Applications for Payment

We prepare and manage applications for payment to ensure they’re compliant, properly evidenced, and submitted on time — helping you get paid faster and avoid disputes.

4. Variations & Change Management

We identify and value variations to scope, prepare supporting documentation, and negotiate with main contractors to ensure fair compensation for additional works.

5. Cash Flow Forecasting & Financial Tracking

We provide clear and accurate forecasts so you can track costs, revenue, and profit across each project, keeping your cash flow under control and avoiding unpleasant surprises.

6. Contractual Dispute Support

If commercial tensions arise, we can communicate directly with the main contractor’s QS or commercial manager on your behalf, using professional understanding of their processes to reach quick, fair resolutions.

7. Final Accounts

We prepare and agree your final account to ensure all completed works are included and that you receive the full payment you’re entitled to.

8. Commercial Mentoring

We also offer mentorship for subcontractor teams, helping you build internal commercial awareness, streamline processes, and manage paperwork more effectively in future.
