Do You Need to Be a CHAS Accredited Contractor?

If you’re self-employed or running a small construction business, a common question is:

“Do I actually need CHAS accreditation to work?”

The honest answer is: it depends on the type of work you do and who you work for.

Quick Answer

• Domestic work only? → No, not strictly required
• Working for contractors, councils, or commercial clients? → Yes, almost always required
• Want to win more contracts? → CHAS or SSIP is essential
• If you’re not accredited yet, start with our CHAS accreditation step-by-step guide.

Domestic Market

If you only work directly for homeowners:

• You are not legally required to have CHAS accreditation
• Most domestic clients won’t ask for it

However, don’t mistake this for no responsibility.

Under UK health and safety law, you still have a duty of care to:

• Yourself
• Anyone working with you
• Members of the public

If something goes wrong (accident, injury, unsafe work), you are still liable, with or without CHAS.

Bottom line: You can operate without CHAS in domestic work, but you still need proper safety systems in place.

Construction & Commercial Market

If you want to work in the wider construction industry:

CHAS (or equivalent) becomes essential.

Main contractors, developers, housing providers, and local authorities will almost always require:

• Proof of health & safety compliance
• A recognised accreditation standard
• Evidence before allowing you on-site

The most widely recognised scheme is:

• CHAS

But it’s part of a wider system called:

• Safety Schemes in Procurement

All SSIP schemes assess the same core criteria, including:

• Constructionline
• SMAS Worksafe
• SafeContractor

This means:

You don’t have to choose CHAS, but you must have an SSIP accreditation to compete.

Does Business Size Matter?

Yes, especially when it comes to compliance requirements.

Sole traders & businesses under 5 employees

• You still need health & safety systems
• You can get CHAS / SSIP accreditation
• You don’t legally need a full-time safety advisor

Businesses with 5+ employees (including subcontractors)

• You must have access to a competent health & safety advisor
• This is a legal requirement under:
  • Management of Health and Safety at Work Regulations 1999

Most small contractors meet this by using a retained (outsourced) competent person service

What Does CHAS Actually Assess?

CHAS (and all SSIP schemes) measure your business against core health & safety standards.

These include:

• Health & Safety Policy
• Access to Competent Advice
• Training and Competence
• Risk Assessments & Method Statements (RAMS)
• Monitoring, Audit & Review
• Workforce Engagement
• Accident Reporting & History
• Subcontractor Management
• Cooperation & Communication
• Welfare Provision
• Hazard Identification & Control

In simple terms, CHAS proves your business can work safely and professionally on construction projects.

Why Most Contractors Choose CHAS Anyway

Even if it’s not mandatory for your current work, many contractors get accredited because it:

• Opens doors to higher-value contracts
• Helps you pass pre-qualification questionnaires (PQQs)
• Builds trust with clients instantly
• Reduces repeated compliance checks

Final Verdict

• Domestic-only work? CHAS is optional, but safety compliance is not
• Construction or commercial work? CHAS or SSIP is effectively required
• Want to grow your business? Accreditation becomes a competitive advantage
• To stay compliant, it’s important to understand CHAS renewal requirements each year.

Simple Rule to Remember

No CHAS = limited opportunities
CHAS (or SSIP) = access to the real construction market

Frequently asked questions

Do I need to be a CHAS accredited contractor?

You do not normally need CHAS accreditation if you only work directly for domestic homeowners. However, if you want to work for main contractors, commercial clients, housing providers, developers or local authorities, CHAS or another SSIP accreditation is often required before you can start work.

Is CHAS a legal requirement?

CHAS accreditation itself is not a legal requirement. However, UK contractors still have legal duties to manage health and safety. CHAS helps demonstrate that your business has suitable health and safety arrangements in place.

Do domestic contractors need CHAS accreditation?

Domestic contractors are rarely asked by private homeowners for CHAS accreditation. However, they still have a duty of care to protect themselves, workers, subcontractors and members of the public from harm.

Do small contractors need CHAS accreditation?

Small contractors often need CHAS accreditation to work in the commercial construction market. Main contractors, local authorities and larger clients commonly require CHAS or another SSIP certificate before allowing subcontractors onto the site.

Can I use another SSIP scheme instead of CHAS?

Yes. CHAS is one SSIP accreditation provider, but other schemes, such as Constructionline, SafeContractor, SMAS, CQMS, and PQS, can also assess contractors against the same SSIP core criteria. The right choice depends on what your client or tender requires.

Do I need a competent health and safety advisor for CHAS?

If you employ five or more people, including subcontractors or self-employed workers under your control, you must have access to competent health and safety advice. Many small contractors meet this requirement by using an outsourced competent person service.

What does CHAS check?

CHAS checks whether your business has suitable health and safety arrangements. This includes your health and safety policy, competent advice, training records, risk assessments, method statements, accident reporting, workforce involvement, subcontractor management and welfare arrangements. Review the CHAS assessment criteria.

Why do main contractors ask for CHAS?

Main contractors use CHAS because they must control health and safety risks across their supply chains. CHAS gives them evidence that a subcontractor has been assessed against recognised SSIP health and safety standards.

SSIP Accreditation and CHAS: What UK Contractors Need to Know (2026 Guide)

If you’re a contractor trying to win work in the UK construction sector, you’ve likely come across SSIP accreditation and CHAS.

SSIP is the system. CHAS is one of the most recognised schemes within it.

If you want to work for main contractors, councils, or commercial clients, you’ll almost always need one of them.

If you’re applying through CHAS, follow our CHAS accreditation step-by-step guide.

What Is SSIP Accreditation?

Safety Schemes in Procurement (SSIP) is an umbrella organisation that:

• Standardises health & safety assessments
• Reduces duplication across multiple schemes
• Ensures all member schemes assess the same core criteria

In simple terms: SSIP means “one standard, recognised everywhere.”

What Is CHAS?

CHAS (The Contractors Health and Safety Assessment Scheme) is:

• One of the most widely recognised SSIP schemes
• Used by main contractors, developers, and local authorities
• A fast way to prove your business meets health & safety requirements
• How to get CHAS accreditation step-by-step

Quick Comparison

What Do SSIP & CHAS Actually Assess?

All SSIP schemes (including CHAS) assess the same core areas:

• Health & Safety Policy
• Competent Advice
• Training & Competence
• Risk Assessments & RAMS
• Accident Reporting
• Workforce Involvement
• Monitoring & Review
• Subcontractor Management
• Welfare & Communication

This is why: If you pass CHAS, you meet the SSIP standard.

Do You Need SSIP or CHAS?

You DO need it if you want to:

• Work for main contractors
• Bid for local authority or public sector work
• Access construction frameworks
• Get onto approved supplier lists
• Do you need CHAS accreditation as a UK contractor?

You may not need it if:

• You only work for domestic homeowners
• You don’t plan to enter commercial construction

But realistically, No SSIP = limited growth in construction

CHAS vs Other SSIP Schemes

CHAS is not the only option. Other SSIP schemes include:

• Constructionline
• PQS
• SMAS Worksafe
• SafeContractor

All assess the same standards, but:

• Some clients specify CHAS by name
• Others accept any SSIP-accredited scheme
• You may also benefit from CHAS Deem to Satisfy if you already hold SSIP certification.

Choosing the right one depends on:

• Your target clients
• Tender requirements
• Budget

How Much Does SSIP / CHAS Cost?

Typical entry-level costs:

• CHAS: from ~£429 + VAT
• PQS – £49 + VAT
• SMAS: from ~£317 + VAT
• SafeContractor: from ~£419 + VAT
• Constructionline Bronze: from ~£498 + VAT
• To compare options, see our CHAS vs Constructionline guide.

Important: The highest cost is often getting your documents compliant, not the scheme fee.

Why Contractors Fail SSIP / CHAS

Common mistakes include:

• Outdated health & safety policy
• Missing RAMS
• No competent safety advisor
• Weak or generic documents
• Expired insurance
• No training evidence

Fix these early, and approval becomes straightforward. Common reasons CHAS applications fail and how to avoid them

Benefits of CHAS / SSIP Accreditation

• Win more contracts
• Meet pre-qualification requirements
• Build trust with clients
• Reduce repeated assessments
• Improve your safety systems

Final Verdict

• SSIP = the standard
• CHAS = one of the best-known ways to meet it

If you want to grow in construction, SSIP accreditation isn’t optional; it’s expected.
