- WHAT WE DO
Commercial support at every stage
From pricing the tender to getting paid on site — we cover the commercial side of your business so nothing slips through the cracks.
01 — Tendering & Estimating
Price every job accurately, fast
We produce fully costed tender packages — labour, materials, margin, marked-up drawings and a client-ready quote letter. Priced to win, structured to protect you.
From £180 + VAT
02 — TENDER NEGOTIATION
Hold you position under pressure
When the main contractor pushes back on your price, we handle the negotiation on your behalf — professionally, with your margin protected.
Fee agreed on enquiry
03 — VALUATIONS & APPLICATIONS
Get paid what you're owed, on time
Regular payment applications submitted to your programme. Variation management, pay less notice responses, and ongoing contract position reviews.
Standalone or retained
04 — Ongoing Commercial Support
Get paid what you're owed, on time
Contract reviews, material uplift applications, variation pricing, ad-hoc commercial advice — available when you need us, without the cost of a full-time QS.
- WHO WE WORK WITH
Built for subcontractors
Most QS firms work for developers and main contractors. We work exclusively for subcontractors — which means we understand your contracts, your relationship with the main contractor, and what it takes to win work and protect your margin.
Whether you're a growing masonry firm pricing for a PLC housebuilder for the first time, or an established carpentry contractor drowning in paperwork — we can step in and handle it.
No long-term contracts required. Start with a single tender and see the difference.
