What Does a Bill of Quantities Cost in Nigeria in 2026?
One of the first questions Nigerian self-builders ask when they hear about a Bill of Quantities is simply: "How much will it cost me to get one?" The honest answer is that the cost varies widely — from zero for a tool-generated estimate to over ₦800,000 for a comprehensive professionally prepared document on a large project. Understanding what drives that range will help you decide how much to spend and what you should expect to receive for your money.
In 2026, the typical cost of a professionally prepared Bill of Quantities in Nigeria ranges from ₦80,000 for a small 2-bedroom residential project to ₦800,000 and above for a large commercial building. For the most common request — a 3-bedroom bungalow — expect to pay ₦150,000 to ₦380,000 from a reputable Quantity Surveyor.
The NIQS Recommended Fee Scale for Nigeria
The Nigerian Institute of Quantity Surveyors (NIQS) publishes a Scale of Professional Charges that guides fee negotiations across the profession. The recommended rate for preparing a Bill of Quantities for a residential building is 2 to 3 percent of the estimated construction value. For projects where the final construction value is not yet known, most QS professionals use their own estimate of the likely construction cost to determine their fee. Here is how that percentage translates into naira for common project sizes in 2026:
| Project Type | Estimated Construction Value | 2% Fee | 3% Fee |
|---|---|---|---|
| 2-bedroom flat (standard) | ₦12M – ₦18M | ₦80,000 | ₦200,000 |
| 3-bedroom bungalow (standard) | ₦22M – ₦35M | ₦150,000 | ₦380,000 |
| 3-bedroom bungalow (luxury) | ₦38M – ₦60M | ₦260,000 | ₦650,000 |
| 4-bedroom bungalow (standard) | ₦30M – ₦50M | ₦200,000 | ₦550,000 |
| 4-bedroom duplex (standard) | ₦55M – ₦90M | ₦380,000 | ₦800,000 |
| Block of 4 flats | ₦80M – ₦130M | ₦550,000 | ₦1,300,000 |
| Small commercial building | ₦100M – ₦250M | ₦700,000 | ₦2,000,000 |
In practice, many freelance Quantity Surveyors prefer to charge a flat fee for standard residential projects rather than a percentage. A flat fee of ₦100,000 to ₦250,000 for a 3-bedroom bungalow BoQ is common in Abuja, Ibadan, and Enugu. Lagos QS professionals tend to charge 15 to 25 percent more than rates in other cities.
QS Firm vs Freelance Quantity Surveyor — Which Costs More and Why
There are two main sources of Bill of Quantities services in Nigeria:
- Registered QS firms (corporate practice): These are partnership or limited liability firms registered with NIQS and CORBON (Council for the Regulation of Engineering in Nigeria). They have offices, multiple staff, professional indemnity insurance, and formal engagement letters. Their fees are typically 30 to 60 percent higher than freelancers for the same project. However, their BoQs carry professional liability — if there is a significant error in the document, the firm is accountable. Banks and government agencies generally insist on BoQs from registered firms.
- Freelance Quantity Surveyors: Individual QS practitioners working independently, often graduates or young professionals building their client base. They typically charge ₦80,000 to ₦200,000 for a standard residential BoQ. Quality varies significantly — some produce excellent, detailed documents while others produce thin estimates dressed up as BoQs. Always request a sample of their previous work before engaging.
What Should Be Included in the BoQ Fee?
Before agreeing any QS fee in Nigeria, confirm in writing that the scope of work includes all of the following:
- Full taking-off: Physical measurement of all quantities from architectural and structural drawings — not estimates or rule-of-thumb approximations
- Pricing with current market rates: Unit rates based on current Nigerian material and labour prices, not generic rates from a textbook or a previous project
- Complete BoQ document: A properly formatted spreadsheet or bound PDF with all 8 to 10 work sections, individual line items, section subtotals, and a summary page
- Written specification notes: A description of materials and workmanship standards for each section — so contractors know exactly what they are pricing
- One revision: The ability to update the BoQ once, free of charge, if the design changes before work starts. Subsequent revisions should be separately quoted.
Items that are usually charged separately include: tendering management (inviting and evaluating contractor bids), interim valuations during construction, variation pricing, and final account preparation. For a self-builder managing their own project, the BoQ document itself is the essential deliverable — you can manage the rest yourself.
How to Evaluate Whether a QS Quote Is Reasonable
When you receive a quotation for BoQ preparation in Nigeria, ask yourself these questions before accepting:
- Does it specify what drawings they will work from? A fee quoted without seeing your drawings is speculative. A good QS will want to review the drawings before quoting so they understand the complexity of the project.
- What format will the BoQ be delivered in? You should receive a fully editable Excel spreadsheet plus a formatted PDF. If a QS offers only a PDF, they may be protecting a template rather than doing a full take-off for your specific project.
- What is the turnaround time? For a 3-bedroom bungalow, 10 to 15 working days is standard. A 3-day turnaround for a full BoQ is a red flag — it may indicate that the QS is using a standard template rather than actually measuring your specific design.
- Are they NIQS registered? Check the NIQS website or ask to see the practitioner's membership certificate. Unregistered individuals offering BoQ services have no professional accountability if their document turns out to be inaccurate.
When Is a Professional BoQ Worth the Cost?
A professionally prepared Bill of Quantities almost always pays for itself when any of these conditions apply:
- Your project is above ₦15 million in total construction value — at this scale, even a 5 percent improvement in cost control recovers the QS fee many times over
- You are tendering to multiple contractors and need comparable bids — a BoQ makes this possible; without it, different contractors price different scopes and you cannot compare them fairly
- You are applying for a bank construction loan — Nigerian banks require a QS-prepared BoQ as part of the loan application for any project above ₦10 million
- You are building for the first time — first-time self-builders without a BoQ in Nigeria typically overspend by ₦3M to ₦10M on a 3-bedroom bungalow
- Your design is non-standard — irregular floor plans, split levels, curved walls, or complex rooflines require specialist measurement that generic cost tools cannot handle
