If you work in construction or contracting in the UK, you’ve probably heard the term “CHAS”. But what does it actually mean? And do you really need it? In this guide, we break down everything you need to know about CHAS certification, from what it is to the documents you’ll need, and whether it’s worth your time and money.
At BizGrow Holdings, we help UK businesses navigate accreditations like CHAS with ease. Let’s get into it.
CHAS Certification Meaning
CHAS stands for Contractors Health and Safety Assessment Scheme. It is a UK-based accreditation scheme that checks whether your business meets proper health and safety standards.
In simple terms, CHAS tells potential clients: “This company takes health and safety seriously.”
CHAS was set up to cut through the hassle of multiple pre-qualification checks. Instead of filling in a different form for every client, you go through one CHAS assessment. That result is then shared with over 2,500 CHAS clients across the UK.
CHAS is recognised across many industries, including:
- Construction and building trades
- Facilities management
- Manufacturing and engineering
- Transport and logistics
- Education and the public sector
If your clients are asking for proof of your health and safety compliance, CHAS is usually the fastest and most trusted way to provide it.
SSIP CHAS Certification
You may have seen the term “SSIP” alongside CHAS. SSIP stands for Safety Schemes in Procurement. It is an umbrella body that oversees several health and safety accreditation schemes in the UK, and CHAS is one of them.
Here’s why this matters:
When you get CHAS Standard or Advanced accreditation, you also receive SSIP accreditation. That means you can use your CHAS certificate to satisfy the SSIP requirements of many other clients, too. This is known as “deemed to satisfy”; it avoids you having to apply to multiple schemes separately.
In practice, this saves contractors time and money. One assessment, one fee, and you’re recognised across a wide network of SSIP-accepting clients.
Other SSIP members include SafeContractor, Constructionline, and SMAS. But CHAS is widely considered the UK’s most trusted and popular SSIP scheme.
CHAS Certification Levels
CHAS offers three levels of accreditation. Each level has different requirements, costs, and benefits. Here’s a simple breakdown:
1. CHAS Standard
This is the entry-level option. It covers health and safety assessment plus SSIP accreditation.
Good for:
- Small contractors and sole traders
- Businesses new to formal accreditation
- Those tendering for straightforward contracts
2. CHAS Advanced
CHAS Advanced builds on Standard and also covers PAS 91 requirements. You’ll need to demonstrate compliance in nine areas of risk management, including health and safety, equality and diversity, and environmental management.
Good for:
- Mid-size contractors
- Businesses tendering for larger commercial projects
- Those wanting to meet PAS 91 standards
3. CHAS Elite
CHAS Elite is the highest level. It includes everything from Standard and Advanced, plus the Common Assessment Standard (CAS). You’ll need to show compliance in 13 risk management areas.
Since June 2024, CHAS Elite (Common Assessment Standard) is now required by UK public sector bodies when pre-qualifying contractors for works contracts, in line with government Procurement Policy Note (PPN) 03/24.
Good for:
- Larger businesses and main contractors
- Those bidding for public sector work
- Companies want maximum visibility and credibility
What Documents Do I Need for CHAS?
This is the question most people ask first. The exact documents you need can vary slightly depending on your trade, the size of your business, and which CHAS level you’re applying for. But in general, here’s what you’ll need to prepare:
Core Health & Safety Documents
- Health and Safety Policy signed, dated and up to date
- Risk Assessments and Method Statements (RAMS)
- Construction Phase Plans (where relevant)
- Records of health and safety management and organisation
Insurance Documents
- Employers’ Liability Insurance certificate
- Public Liability Insurance certificate
- Professional Indemnity Insurance (if applicable)
Training & Competency Evidence
- Training certificates for you and your staff (e.g. CSCS, IOSH, NEBOSH)
- Health and safety induction records
- Toolbox Talk attendance sheets
- Details of your health and safety advisor or competent person
Operational & Maintenance Records
- PAT testing and equipment maintenance records
- Accident and incident records
- Health surveillance records (where relevant)
- Details of any subcontractors used
For CHAS Advanced and Elite, you may also need:
- Equality and diversity policy
- Environmental management policy
- Financial information (for Elite/CAS)
- Modern slavery statement
- Quality management documentation
Tip: Gather all your documents before you start the online assessment. It will save you a lot of back and forth.
How to Get a CHAS Certification
Getting CHAS certified is simpler than many people expect. Here’s how the process works:
Step 1:
Choose your level: Decide whether Standard, Advanced, or Elite is right for you based on the type of work you do and what your clients require.
Step 2:
Register on the CHAS portal: Go to chas.co.uk and create an account. You’ll complete an online questionnaire about your health and safety practices.
Step 3:
Upload your documents: Submit the required evidence through the online portal. You can do this at your own pace.
Step 4:
Assessment: A CHAS assessor will review your submission. They may come back with questions or requests for extra information.
Step 5:
Receive your certificate: Once approved, you’ll receive your CHAS accreditation certificate. This is valid for 12 months and must be renewed annually.
You can also use an accreditation support company (like BizGrow Holdings) to help you prepare your documents and complete the application correctly the first time. This reduces delays and makes the process much less stressful.
How Hard Is It to Get CHAS?
The honest answer: it depends on how organised you are.
If you already have your health and safety documents in order, signed policies, up-to-date risk assessments, and training records, then the application is fairly straightforward. Most businesses complete the assessment in a few hours to a few days.
If you’re starting from scratch with little formal documentation, it will take longer. You’ll need to write a health and safety policy, carry out risk assessments, and gather proof of training before you can apply.
Common reasons applications get rejected or delayed:
- Health and safety policy not signed or out of date
- Missing or incomplete risk assessments
- No evidence of relevant training or qualifications
- Insurance documents that are expired or insufficient
The key is preparation. Sort your documents first, then apply.
How Long Does CHAS Take?
CHAS assesses applications on a rolling basis. Most straightforward applications are assessed within a few working days once all documents have been submitted.
However, the total time depends on how quickly you can gather your paperwork. If you need to write a health and safety policy from scratch or collect training certificates from staff, this can add days or weeks to the process.
Typical timeframes:
- Documents already in order: a few days to 2 weeks
- Some documents are missing: 2 to 6 weeks
- Starting from scratch: up to 2 months
If you’re working towards a contract deadline, start early. Don’t leave it to the last minute.
Is CHAS Accreditation Worth It?
Short answer: yes, in most cases.
CHAS is used by over 2,500 clients across the UK. Many large organisations, both public and private sectors, will not consider a contractor unless they hold CHAS or an equivalent SSIP accreditation. Without it, you could be filtered out of tenders before your name is even seen.
Here’s what CHAS accreditation can do for your business:
- Open doors to bigger contracts and public sector work
- Reduce time spent on pre-qualification forms
- Build trust with clients and partners
- Show you take health and safety seriously
- Keep you compliant with UK health and safety law
- Give you a competitive edge over non-accredited competitors
For most contractors, a single extra job secured through CHAS more than covers that cost. Many CHAS members also receive member discounts on e-learning, insurance and business tools, which can offset the fee even further.
If you’re serious about growing your contracting business in the UK, CHAS is not a luxury; it’s a practical investment.
Conclusion
CHAS certification is one of the most recognised health and safety accreditations in the UK. It proves your business is compliant, competent, and safe to work with. Whether you’re a small sole trader or a growing contracting firm, there’s a CHAS level that suits your business.
The key steps to getting CHAS are simple: know which level you need, prepare your documents in advance, and submit a clean, complete application.

Frequently Asked Questions (FAQs)
1. Who needs CHAS certification?
Any contractor or business that wants to tender for work with clients who require health and safety pre-qualification. This is especially common in construction, facilities management, and the public sector. If your clients are asking for SSIP accreditation, CHAS covers that too.
3. How long is the CHAS certification valid?
CHAS accreditation is valid for 12 months. It must be renewed every year. You can begin the renewal process before your current certificate expires, so you avoid any gap in accreditation.
4. Can a sole trader get CHAS?
Yes. Sole traders and self-employed contractors can apply for CHAS. The assessment process is scaled to the size of your business, so smaller businesses are not penalised for having fewer staff or simpler operations.
5. What happens if my CHAS application is rejected?
If your application is unsuccessful, CHAS will tell you why and what you need to improve. Common issues are missing documents, outdated policies, or insufficient evidence of training. You can resubmit once you’ve made the necessary changes. Working with an accreditation support company can help you get it right the first time.
