Overview of the BCA Directory (Answer the main question early)
The bca directory is the official online listing maintained by Singapore’s Building and Construction Authority for licensed builders, registered contractors, suppliers and other firms in the built environment. You can use the online BCA directory to verify whether your builder or contractor is properly registered and allowed to carry out works in singapore before you hire them.
This guide explains how homeowners, business owners and government officials can check the BCA registered directory step by step. The directory helps support a safe, quality and sustainable built environment by making registration information available for public access online.

What Is the BCA Directory and Why It Matters
The bca directory generally refers to the Building and Construction Authority’s online e-Directory of registered contractors, licensed builders, suppliers and related firms. It is a centralized database for verifying firms in Singapore’s built environment, and the BCA Directory is maintained by the Building and Construction Authority of Singapore.
BCA is Singapore’s national construction authority. As a singapore government agency, it oversees building safety, sustainability, contractor registration and licensing for the built environment. The directory matters because it helps developers and government agencies confirm a builder’s legal registration before hiring.
The directory complements systems such as the Contractors Registration System and the Licensed Builders registry. CRS is Singapore’s registry for construction firms, and the Contractors Registration System is required for public sector construction project tenders. Businesses must obtain a license under the Builders Licensing Scheme for general building works.
You can refer to BCA’s official information on the Contractors Registration System for current requirements, workheads and registration conditions.
Types of Firms Listed in the BCA e‑Directory
The online bca directory is divided into registries based on business type and service offered. The database is organised by registry category, workhead and registration details so users can search for firms that match the nature of the work.
Registered Contractors are the largest group. The BCA directory lists registered contractors in Singapore, including firms involved in general building, civil engineering, mechanical and electrical work, and specialised construction trades. There are about 50 types of workheads in CRS, and companies in the directory are classified by specific Workheads to indicate their authorized work.
Licensed Builders are firms licensed to undertake building works under the Building Control Act. This includes general builders, commonly associated with GB1 and GB2 classes, as well as specialist builders for works such as piling, precast concrete and ground support. The directory includes licensed builders and contractors, so it is useful for checking both licensing and registration details in one place.
Suppliers Registry entries cover companies providing construction materials, equipment and building products used by contractors. These suppliers may be relevant when a project owner needs to verify whether a company is recognised for supplying specific built environment products or services.
Facilities Management Registry entries cover firms involved in building operations and upkeep. The Facilities Management Registry includes firms providing maintenance and cleaning services, as well as related services such as housekeeping, landscaping and pest control.
Each listing typically shows the company name, registration or licence type, workhead codes, grades and validity dates. The directory displays the expiry date of registrations to prevent hiring non-compliant firms.
Step‑by‑Step: How to Check the BCA Registered Directory for Your Builder
This is the main practical section on how to check the BCA registered directory for your registered builder.
Step 1: Go to the official BCA website.
Start from an official BCA page, such as the list of firms registered in BCA registries. Use official sg websites whenever possible. As an added precaution, notice whether the page uses https, shows a lock symbol in the browser, and belongs to a gov domain. Official Singapore Government websites often display the sg crest, and secure websites help protect users from a scam.
Step 2: Open the e‑Directory or search page.
Navigate to the relevant search function, such as “Search for Registered Contractors” or “Search for Licensed Builders.” The directory is available for public access online, so you do not need special access just to view listed firms.
Step 3: Search by company name.
Type the builder’s full or partial legal name into the search field. If your quote shows a trading name, ask the contractor for the registered legal entity name as stated in ACRA or the contract. This avoids selecting the wrong company when several contractors have similar names.
Step 4: Search by UEN or registration number if available.
If the quotation, invoice, business profile or contract includes a UEN, use that data to narrow the search. Searching by UEN is often more reliable than searching by name because it identifies the exact legal entity.
Step 5: Apply registry and workhead filters.
Use filters such as “Registered Contractors,” “Licensed Builders,” or the relevant workhead. For example, CW01 refers to General Building, CW02 refers to Civil Engineering, ME05 refers to Electrical Engineering, and FM01 refers to Facilities Management. These filters help you find contractors authorised for the specific type of work you need.
Step 6: Check the listing details carefully.
Look at the company name, registered office address, workheads, grades, licence or registration status, and expiry date. Active status and registration validity can be checked through the directory. The BCA Directory can be used to verify a contractor’s credentials before hiring, but you still need to confirm that the scope of registration matches your project.
Step 7: Confirm the status and project fit.
The status should be active, and the registration should be valid beyond the date you plan to appoint the firm. The workhead and grade should also match the type and scale of the project. Registered contractors receive grades that determine their maximum project bidding value, so grade is not just a label.
You do not need bank log in details, Singpass credentials or any request to transfer money just to view the public directory. If a website or message asks you to share sensitive information for a simple directory check, stop and verify the source through official channels. BCA and other sg government agencies communicate through official contact points, not by asking the public for private banking information through suspicious links. If you receive a message where links end in an unfamiliar domain, treat it with caution.
Verifying a Builder for Home Renovation or Small Projects
For a home renovation, do not only ask whether the contractor is “BCA registered.” Check whether the builder is listed under a workhead that fits the actual job. A small apartment renovation may involve general building, interior finishing, electrical works or air-conditioning works rather than a large civil engineering category.
For example, a contractor handling interior fit-out should have a relevant construction-related workhead, while electrical work may require an appropriate mechanical and electrical workhead such as ME05. If the contractor is doing structural or general building works, check whether the listing reflects the right building registration or builder licence.
Compare the legal entity name in the bca directory with the name on the quotation, contract and invoice. If “ABC Renovation” appears on a name card but the contract is issued by a different company, search the legal entity and UEN before signing. This simple check can prevent confusion with similarly named firms.
Before paying a deposit, take a screenshot or print the directory entry as a reference. Keep it together with your contract, payment records and correspondence. This gives you a dated record of what you checked before hiring.
Verifying a Contractor for Public Sector or Large Projects
For public sector and large projects, the directory check is more than a basic background check. Firms bidding for public sector projects must be appropriately registered in the CRS and/or Licensed Builders registry as reflected in the bca directory.
Project owners and consultants should check the contractor’s workhead and grade against the tender requirements. Developers and property owners use the registry to ensure compliance with technical and financial requirements. The grade helps confirm whether the firm is suitable for the expected contract value and whether it has met BCA’s financial, personnel and track record criteria for that category.
Government officials and public agencies commonly rely on the directory to verify that contractors meet minimum financial, technical and safety criteria. It is also important to check the expiry date. A contractor whose registration expires soon may be valid at submission but unsuitable if the registration will lapse before or during the expected project period.
Since 1 June 2025, all firms must register with CRS to meet the new CRS requirement where it applies, including public sector tender participation and foreign construction worker hiring. Registration with CRS is mandatory for hiring foreign workers, including relevant Work Permit or S Pass construction workers.
Understanding Workheads, Grades and Registration Status
BCA workheads are codes that classify the type of construction, supply or facilities management activity a firm is approved to carry out. They make the bca directory easier to search because you can match a company to the work you actually need.
Common examples include CW01 for General Building, CW02 for Civil Engineering, ME01 for Air-Conditioning, ME05 for Electrical Engineering, FM01 for Facilities Management and FM02 for Housekeeping. A firm can appear under more than one workhead if it has obtained approval for more than one category. Firms can apply for new or additional workheads in CRS when they expand their services or meet the relevant requirements.
Grades show the scale at which a firm is registered. In simple terms, grades are tied to tendering limits or project value limits, based on factors such as financial capacity, track record and technical personnel. For example, higher grades usually allow a contractor to bid for larger projects, while lower grades are intended for smaller contract values.
The status field is equally important. An active status means the registration is currently valid. An expired status means the firm’s registration has lapsed. A suspended status indicates that the firm should not be treated as fully valid for the affected registration. A deregistered status means the firm is no longer registered for that category.
Choosing a builder with the correct workhead and adequate grade is essential. A high grade does not automatically mean better workmanship, and a valid listing does not replace checks on pricing, quality, safety record and client references. Still, the directory is the first table of facts you should review before shortlisting a contractor.
Safety, Compliance and the Role of the Building and Construction Authority
The Building and Construction Authority plays a central role in maintaining building safety and regulatory standards across Singapore. Its oversight extends across the built environment, including building works, regulated systems and areas that affect public safety.
The directory supports enforcement by making it easier for the public to distinguish properly registered contractors from unregistered operators. When users can search for official records, it becomes harder for unregistered firms to misrepresent their status.
Registered contractors must comply with applicable codes of practice, safety regulations and quality standards set by the Building and Construction Authority. This matters because proper registration is linked to safer outcomes, such as structural safety, code-compliant installations and responsible site management.
A liveable built environment depends on more than attractive buildings. It depends on safe design, competent construction, reliable maintenance and clear accountability in a dynamic industry.
Common Mistakes When Checking the BCA Directory (and How to Avoid Them)
A common mistake is searching by a trade name instead of the legal entity name. If you cannot find the firm, ask for its UEN and search again using the legal name stated on the contract.
Another mistake is relying on old certificates or screenshots. Always check the updated listing in the bca directory because registration status and expiry dates can change.
Some users stop after finding a similar company name. Do not do that. Cross-check the UEN, office address, phone number where available, workheads and grades to confirm you have the right company.
Another error is assuming that any BCA listing is enough. The workhead must match the work. A firm registered for one trade may not be the right contractor for a different type of building work.
Finally, do not treat directory registration as a workmanship guarantee. It confirms regulatory registration, not whether the firm is the best value, most reliable or most experienced for your project. Ask for references, review past projects and read the contract terms before you commit money.
When to Contact BCA or Relevant Authorities
Contact BCA if you cannot find a contractor in the directory but the firm claims to be registered or licensed for building works. You can also approach BCA if you need clarification on workhead scope, registration categories or how to interpret directory information for a specific project type.
Suspected misuse of registration details, misrepresentation of status or unsafe building practices should be reported to the appropriate BCA department. For general enquiries, BCA’s main service centre is located at 52 Jurong Gateway Road, #11‑01, Singapore 608550. Official contact channels, including the general hotline and online enquiry routes, are available through BCA’s website.
When in doubt, verify through official sources before signing a contract or making payment. A few minutes of checking can prevent serious compliance, safety and financial problems later.
Summary: Using the BCA Directory Before You Hire
Always check the BCA registered directory before engaging any builder, contractor or supplier for construction-related works. Access the official BCA e-Directory, search by company name or UEN, confirm workheads, grades and status, and ensure the registration is active and appropriate for your project. Making the bca directory part of your contractor selection process helps homeowners, businesses and public agencies support safer, compliant building works across Singapore’s built environment.
