Why We Exist
Every construction project runs on numbers before it runs on bricks and mortar. Get the numbers wrong at the outset — underestimate a trade, miss a preliminary cost, misjudge a tender price — and the consequences follow the project all the way to completion: budgets blown, tenders lost, and margins eaten alive by costs nobody accounted for.
Bidders Support exists to make sure that doesn't happen. We are a dedicated UK-based team of qualified Quantity Surveyors providing detailed, accurate cost estimates and tender pricing across the full scope of construction work — from initial architectural concept and planning approvals through to structural steel, MEP, and decoration on site.
Whether you're a self-builder pricing a single home extension, a main contractor pricing a competitive £500k tender, or a developer costing a multi-unit residential scheme, we give you numbers prepared the way a senior surveyor would prepare them — comprehensive, defensible, and fully itemised.
Our Mission
To give every UK builder, contractor, and client access to the exact same high standard of quantity surveying and estimating expertise that top-tier firms enjoy, delivered quickly, transparently, and at accessible fixed prices.
Our Vision
To be the premier independent estimating partner for anyone in the UK construction industry who needs to know, with absolute confidence, what a project will cost before committing capital.
Our 6 Core Principles
The standards that govern every estimate, bill of quantities, and tender document we deliver.
1. Accuracy Above All
An estimate is only valuable if you can rely on it. We double-check every quantity take-off, labor rate, and specification note before release.
2. Speed Without Shortcuts
Deadlines make or break tender opportunities. Our 5-day standard delivery and express turnaround options ensure you never miss a submission.
3. Total Transparency
Fixed-price quotes upfront from £75. No hidden percentage charges, no surprise fees — just crystal-clear professional pricing.
4. Strict Confidentiality
Your project plans, confidential tender strategies, client names, and subbie rates are strictly protected and never shared.
5. Direct Surveyor Access
You get direct phone and email access to the specific Quantity Surveyor who priced your project to answer questions and adjust scope.
6. UK-Wide Coverage
Our live regional pricing database reflects true material, labour, and plant rates across London, the Midlands, the North, Scotland, and Wales.
