 - 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.
