How to Register on the CCS ePortal for the CWAS 3 Framework: A Complete Step-by-Step Guide

Why Register on the CCS ePortal?

The Crown Commercial Service (CCS) manages the CWAS 3 framework, one of the largest government construction procurement agreements in the UK with an estimated value of £80 billion. To bid for a place on CWAS 3, you must first be registered on the CCS supplier portal.

Registration is free, but getting it right first time matters. Incomplete or inaccurate registrations can delay your ability to respond to framework opportunities when they open. This guide walks you through every step.

Before You Start: What You Will Need

Before beginning the registration process, gather the following documents and information:

• Company registration number (Companies House)
• DUNS number from Dun & Bradstreet (required for some frameworks)
• VAT registration number (if applicable)
• Annual accounts or financial statements for the last 2-3 years
• Insurance certificates (Public Liability, Professional Indemnity, Employers Liability)
• Health and safety policy and accreditations (SSIP, CHAS, SafeContractor, etc.)
• Environmental policy or ISO 14001 certification
• Quality management documentation or ISO 9001 certification
• Key personnel CVs demonstrating relevant experience
• Case studies of similar civil engineering or construction projects

Step 1: Create Your GOV.UK One Login Account

The CCS ePortal now uses GOV.UK One Login as the authentication gateway for all government digital services. If you already have a One Login account, you can skip this step.

1. Go to supplierregistration.cabinetoffice.gov.uk
2. Click "Create an account" or "Sign in with GOV.UK One Login"
3. Enter your work email address (use a company email, not personal)
4. You will receive a verification code by email. Enter it to confirm your identity
5. Set up two-factor authentication using either an authenticator app or SMS
6. Complete your personal profile with your full name and job title

Top tip: Use a shared company email address (e.g. bids@yourcompany.co.uk) rather than a personal email. This ensures continuity if staff change roles.

Step 2: Register Your Organisation

Once your personal account is set up, you need to register your organisation on the Central Digital Platform.

1. Select your organisation type (limited company, partnership, sole trader, etc.)
2. Enter your Companies House registration number. The system will auto-populate your company details
3. Confirm your registered office address and trading name
4. Add your DUNS number if you have one (some CCS frameworks require this)
5. Enter your VAT registration number
6. Specify your company size (micro, small, medium, large) based on employee count and turnover

The system will create a unique supplier identifier for your organisation. Save this reference number for your records.

Step 3: Complete Your Supplier Profile

Your supplier profile is what CCS and buying organisations will see. A thorough, accurate profile improves your visibility and credibility.

Company Information

• Trading name and any subsidiary details
• Primary contact person and their role
• Company website URL
• Brief description of your organisation (keep this focused on construction and civil engineering capabilities)

Financial Information

• Annual turnover for the last three financial years
• Credit rating or financial health indicators
• Details of any County Court Judgments (CCJs), insolvency proceedings, or winding-up orders

Accreditations and Certifications

• ISO 9001 (Quality Management)
• ISO 14001 (Environmental Management)
• ISO 45001 (Occupational Health and Safety)
• SSIP accreditation (CHAS, SafeContractor, Constructionline, etc.)
• CSCS card compliance
• Any sector-specific accreditations relevant to CWAS 3 lots

Step 4: Navigate to the CWAS 3 Framework Opportunity

Once registered, you need to find the CWAS 3 framework opportunity on the CCS procurement platform.

1. Log into the CCS eSourcing portal at crowncommercial.gov.uk
2. Navigate to "Current Opportunities" or "Open Frameworks"
3. Search for "CWAS 3" or "Construction Works and Associated Services"
4. The framework reference is RM6320. You can search directly by this reference number
5. Review the framework overview, lot structure, and associated documents
6. Click "Express Interest" to register your intention to bid

Important: CWAS 3 is currently in the preliminary market engagement phase, with the formal tender expected to be published later in 2026 and an estimated contract start date of 22 July 2026. Register your interest now so you are notified the moment the application window opens.

Step 5: Understanding the CWAS 3 Lot Structure

Before submitting your application, you need to understand which lots are right for your business. CWAS 3 covers four main value bands:

• Lot 1: Minor Works (up to £1.5 million) ideal for SME contractors
• Lot 2: Medium Works (£1.5m to £10 million) for established mid-tier contractors
• Lot 3: Major Works (£10m to £50 million) for large contractors
• Lot 4: Complex Projects (£50 million+) for tier one national contractors

Select the lots that match your proven capability. CCS evaluators will assess your track record against the lot requirements, so only apply for lots where you can demonstrate relevant experience at the appropriate scale.

Step 6: Prepare Your Selection Questionnaire Responses

The CWAS 3 application will include a Selection Questionnaire (SQ), formerly known as the PQQ. This typically covers:

Mandatory Exclusion Grounds

You must confirm that your organisation has not been convicted of certain offences including fraud, corruption, money laundering, or terrorism-related offences.

Discretionary Exclusion Grounds

Disclose any relevant information about tax compliance, environmental breaches, competition law infringements, or professional misconduct.

Economic and Financial Standing

Demonstrate financial stability through audited accounts, insurance cover, and credit references. Minimum turnover thresholds will apply per lot.

Technical and Professional Ability

This is where your application will be won or lost. You need to provide:

• Detailed case studies of similar projects completed within the last five years
• Evidence of technical capabilities and specialist equipment
• Details of your proposed team and their qualifications
• Your approach to health and safety, quality assurance, and environmental management
• Social value commitments and community benefit delivery plans

Step 7: Submit Your Application

When the formal application window opens:

1. Download all tender documents from the CCS eSourcing portal
2. Read every document carefully, paying particular attention to the evaluation criteria and scoring methodology
3. Complete all mandatory sections of the application form
4. Upload supporting documents in the specified formats (usually PDF)
5. Review your submission against the compliance checklist before submitting
6. Submit before the deadline. Late submissions are automatically rejected with no exceptions

Critical reminder: CCS frameworks have strict deadlines. There are no extensions. Plan to submit at least 48 hours before the closing date to allow for any technical issues with the portal.

Common Mistakes to Avoid

• Applying for the wrong lots: Only apply for lots where you can evidence relevant experience at the correct scale
• Generic case studies: Tailor every case study to the specific lot requirements
• Missing accreditations: Ensure all required accreditations are current and valid at the time of submission
• Poor social value responses: Social value weighting has increased significantly. Prepare specific, measurable commitments
• Last-minute submissions: Portal issues are common on deadline day. Submit early
• Incomplete financial information: Ensure your accounts are filed and up to date with Companies House
