Frequently Asked Questions
How much does a BOQ cost?
Pricing depends on project size and drawing detail. Contact us for a tailored quote.
Do I need a BOQ for a residential extension?
A BOQ is highly recommended for extensions to ensure accurate contractor pricing and reduce cost disputes.
How long does it take to prepare a BOQ?
The timeframe for Bill of Quantities (BOQ) preparation depends on the size and complexity of the project.
For smaller residential construction projects such as extensions or loft conversions, a detailed BOQ can typically be completed within 3–7 working days after receiving the full drawing package.
Larger new builds or more complex projects may require additional time. We always confirm a clear delivery schedule before starting your BOQ preparation.
What drawings do you need?
To prepare an accurate Bill of Quantities in the UK, we usually require:
- Architectural floor plans, elevations and sections
- Construction details and written specifications
- Structural drawings (if applicable)
- Schedules for doors, windows and finishes
If you are unsure whether your drawings are suitable for quantity take-off and BOQ preparation, simply send what you have and we will review it before confirming.
Can you prepare a BOQ for tender submission?
Yes.
Yes, we regularly prepare BOQs for tender submission and contractor pricing. You may also require structured tender pricing support.
Each BOQ is formatted clearly, with measured quantities and defined work descriptions to allow contractors to provide accurate and comparable quotations.
Our BOQ preparation services support residential tenders and construction pricing exercises across the UK.
Is a BOQ required for small residential projects?
A Bill of Quantities is not always mandatory for small residential construction projects, but it is strongly recommended.
Even for modest extensions or refurbishments, a professionally prepared BOQ helps:
- Improve cost transparency
- Reduce pricing variations between contractors
- Support better construction cost planning
- Minimise disputes during the build
For homeowners and developers seeking clear construction cost estimates in the UK, a BOQ provides structure, control and confidence before work begins. For smaller projects, a residential cost estimate may sometimes be more appropriate.
