Online Quantity Surveyor
Online Quantity Surveyor, Remote QS Services for Homeowners, Architects and Builders
PreBuild Cost brings professional quantity surveying to your project anywhere in the country. Our Online Quantity Surveyor and Remote QS Services let you access accurate cost advice and cost control without the need to appoint a local consultant.
Work digitally, save time, and keep control of your budget from concept through to tender and construction.
What an Online Quantity Surveyor does for you
Our Remote QS Services provide the same expertise you would expect from an on-site practice, delivered through secure digital channels.
We measure drawings, take account of desired specification levels and site constraints, and use live UK material and labour rates, combined with decades of real construction and QS experience. Each proposal includes realistic overheads and preliminaries such as site setup, management, welfare, and equipment - giving you a true reflection of what your project will actually cost to deliver.
How we work
Our approach is practical, collaborative, and transparent
​
1. Upload Your Drawings. Securely send us your existing and proposed plans (floor plans, elevations, sections) and any supporting information like site photos or structural drawings.
2. Confirm Scope and Payment. Once we’ve received your files, we will send you a short Fact Finder form to capture project details such as:​
-
Desired specification level (standard / mid / high)
-
Heating, electrical, kitchen and bathroom expectations
-
Site constraints, planning restrictions, or access challenges
This ensures our pricing reflects your actual intentions rather than general assumptions.
We will then confirm the fixed price for our cost proposal and charge payment before commencing the detailed quantity surveying work.
3. We Prepare Your Cost Proposal. Our team - combining 15+ years of on-site build experience with 20–30 years of Quantity Surveying expertise - analyses your files using live UK market rates. We remain completely independent to ensure our figures are neutral and accurate.
4. Receive & Review Your Report. You will receive a detailed PDF report, followed by a 1-hour Teams review with one of our estimators. We will walk you through every line, clarify assumptions, and highlight opportunities to save or reallocate your budget.
5. Use Your Report with Confidence. Your PreBuild Cost proposal is designed to be a decision-making tool, helping you move forward with clarity and control.
You can use your report to:​
-
Validate your budget before committing to final designs
-
Share with architects or engineers to refine drawings
-
Approach builders for quotations with confidence
-
Present verified cost data to banks or lenders
-
Identify potential savings before the project starts
Confidence before construction - that’s what PreBuild Cost is all about.
