SSIP Accreditation: What It Is & Why It Matters for Contractors Guide

What is SSIP? Everything construction businesses need to know about the pre-qualification and winning more work.

What Is SSIP?

SSIP (Safety Schemes in Procurement) is the UK’s national umbrella organisation for health & safety assessment schemes.
Instead of completing multiple safety accreditations, SSIP allows businesses to gain recognition once and have it accepted by many different buyers.

SSIP includes well-known schemes such as:

• CHAS

• SafeContractor

• SMAS Worksafe

• Constructionline (Health & Safety section)

• Alcumus

• BM Trada

If a contractor holds a CHAS, Constructionline, or PQS-approved accreditation, clients can trust that their health & safety systems meet core standards.

Why The Accreditation Matters

SSIP is now one of the most important benchmarks for contractors, subcontractors, and trades in the UK. Here’s why:

1. Win More Work With Recognised Safety Standards

Major contractors, councils, FM companies, and developers increasingly require CHAS, Constructionline, and PQS as part of PQQ or onboarding.

2. Saves Time on Repetitive Safety Pre-Qualification

SSIP prevents businesses from having to complete multiple health & safety assessments for different clients—saving hours of admin every month.

3. Reduces Cost of Compliance

Instead of paying for several accreditations, one SSIP certificate is accepted by many buyers.

4. Demonstrates Legal Compliance

SSIP assessments align with UK safety laws including:

• Health and Safety at Work Act

• Management of Health and Safety at Work Regulations

• CDM Regulations

This reassures clients that your company operates safely and competently.

5. Strengthens Your Brand & Credibility

Displaying an SSIP badge shows customers, inspectors, and project managers that you take safety seriously.

What Do The Assessors Check?

To gain accreditation through any approved scheme, your company must provide evidence of:

Health & Safety Management

• Up-to-date H&S policy

• Competent person support

• Safety arrangements

• Toolbox talks & site inductions

Risk Management

• Recent RAMS

• COSHH assessments

• Site-specific risk controls

Training & Competence

• CSCS/CPCS evidence

• Certificates of training

• Induction process

Incident & Reporting Systems

• Accident records

• RIDDOR procedures

• Near-miss processes

Insurance

• Employer’s liability

• Public liability

• Professional indemnity (if relevant)

If applying for enhanced schemes (e.g., SafePQQ), additional checks cover environmental, quality, and social value standards.

How to Get SSIP Accreditation (Step-by-Step)

Step 1: Choose a Scheme

Decide whether CHAS, SafeContractor, SMAS, or Constructionline best matches your business needs.

Step 2: Complete the Online Assessment

Provide your company details, trade activities, and scope of works.

Step 3: Upload Documentation

Submit your health & safety policy, RAMS, training records, and insurance certificates.

Step 4: Assessment Review

An SSIP auditor reviews everything and may request additional evidence.

Step 5: Receive Your Certificate

Once approved, your business is added to the national database and can display the SSIP badge.

Accreditation lasts 12 months and must be renewed annually.

Most Common Reasons SSIP Applications Fail

Avoid these issues to secure fast approval:

❌ Outdated or missing H&S policy
❌ No recent or adequate RAMS
❌ Missing staff training certificates
❌ Incomplete accident records
❌ Insurance out of date or incorrect
❌ Competent person details missing

Fixing these in advance boosts your first-time pass rate.

SSIP vs Non-SSIP Schemes

SSIP is designed to simplify compliance across the entire supply chain.

Get Accredited and Win More Work!

Is it Worth It for Contractors?

Absolutely. The Accreditation helps you:

✔ Win more work
✔ Reduce tendering admin
✔ Get recognised by major contractors
✔ Demonstrate health & safety competence
✔ Strengthen your professional image

If you want to grow in construction, FM, engineering, or local authority supply chains, SSIP is now an essential requirement—not just a “nice to have.”

Introduction

If you are a construction client looking to check whether the contractor you intend to employ is SSIP (Safety Schemes in Procurement) registered, look no further! We will show you how to determine whether someone is SSIP-registered, giving you the peace of mind you need before starting your project.

Get Accredited and Win More Work!

Contractor

If you are a contractor looking to become SSIP registered, you will need to select an accreditation company. The accreditation companies we work with are:

CHAS
PQS
ConstructionLine
Safe contractor
SMAS
CQMA
Builders profile
Evetta
Other

The most expensive is CHAS, and the least costly is PQS. Due to the Deem to Satisfy system by SSIP, a PQS accreditation is equivalent to a CHAS accreditation, and for a small fee, you can obtain certificates for both.

The driver for selection is normally your customer; if they insist on CHAS, you can get accredited with PQS and request a certificate for CHAS within the process.

Independent Advice

Feel free to call us, and we can advise you on the best selection for your needs. We have completed thousands of applications and understand the market inside out. We don’t mind which company you select; the assessment process is the same, thanks to SSIP.

Checking if a contractor is SSIP registered is straightforward

Go to the SSIP website and click onto the SSIP Portal.

In the search section type in the contractor name and press enter. If they are registered, the SSIP website. portal will give you the registration and renewal date details.

In order to find out the details and check it is the correct company you will need:

• Company full registered
• Registered address

Contacting the company and requesting a copy of their SSIP certificate and any additional and relevant documentation is also advisable. They should be willing to provide you with this information if they are a reputable company.

If you are not happy with the work someone has done for you this would not fall under SSIP. You would need to go to trading standards if you cannot resolve the issue with the company. Trading standards website

PQS accreditation

Find out what PQS accreditation is and how it can save you money and streamline health and safety assessments.

A PQS accreditation is an approved SSIP (Safety Schemes in Procurement) accreditation.

SSIP is an umbrella organisation formed in 2009 to reduce the duplication of health and safety assessments.

SSIP does not carry out the assessments; 30 companies, including PQS, do that.

Why PQS

PQS has designed the most efficient and affordable SSIP accreditation certification process.

PQS was set up to be the most affordable and straightforward SSIP member scheme in the UK market while retaining great value and simple processes.

The deem to satisfy scheme developed by SSIP means a PQS certificate is equal to all other suppliers, for example, CHAS, Constructionline, and Safe Contractor.

While SSIP schemes save money on processes and simplify health and safety procurement for suppliers, they are priced quite differently in the UK market.

SSIP approval is recognised UK-wide, and its purpose is to save contractors time tendering for work.

PQS is approved for all SSIP Categories and/or CDM Duty holders across the United Kingdom and the Republic of Ireland.

For organisations in the United Kingdom, we can provide all the following categories:

– SSIP Approved
– SSIP Approved: Contractor
– SSIP Approved: Principal Contractor
– SSIP Approved: Designer
– SSIP Approved: Principal Designer
– SSIP Approved: IE Contractor
– SSIP Approved: IE Project Supervisor Construction Stage (PSCS)
– SSIP Approved: IE Project Supervisor Design Process (PSDP)
– SSIP Approved: IE Designer

PQS assessment criteria

The PQS assessment criteria are the same as those of all SSIP suppliers. SSIP (Safety Schemes in Procurement) is an umbrella organisation formed in 2009 to reduce the duplication of health and safety assessments.

The PQS assessment standards and requirements are listed below.

• Policy
• Arrangements
• Occupational Health
• Behavioural Management
• Enforcement Actions
• Accident Reporting and Investigation
• Fleet Operations / Management Scheme
• Competent Advice – Corporate and Construction
• Drug and Alcohol Policy
• Training and Information
• Individual Qualifications and Experience
• Monitoring, Audit and Review
• Risk Assessment Leading to a Safe System of Work
• Workforce Involvement
• Co-operation and Co-ordination
• Welfare Provision
• Subcontractors and Sub-consultants
• Contractor
• Principal Contractor
• Designer

Do I need to be a CHAS accredited contractor?

If you are self-employed or a small contractor do you need to be a CHAS accredited contractor. You may be asked to get CHAS or other SSIP certificate. Let us explain the situation to you.

Domestic Market

If you work in the domestic market and want to sail close to the wind, the answer is no, as homeowners will not insist that you work safely.

However, you have a duty of care for yourself and others under UK health and safety legislation. Even working in the domestic market, you will be in trouble if you have a terrible accident or cause harm to others.

Construction Market

The answer is yes if you work in the construction market or want to work there. You will need to have a recognised standard of health and safety.

Main contractors and clients such as local authorities insist that everyone who works for them has a standard of health and safety. They insist as it is part of their health and safety systems.

The most well-known standard is CHAS, but there are other providers of the same standard under the SSIP umbrella. SSIP (Safety Schemes in Procurement) is a organisation that manages accreditation suppliers, to ensure they work to the same standards.

The size of your business matters

If you are self-employed or a small contractor with less than 5 employees, you need CHAS or similar, SSIP but you will not be required to employ a competent person safety advisor.

You must employ a competent person safety advisor if you employ 5 or more people, including sub-contractors or other self-employed people. The easiest way to do this is to use a remote competent person safety advisor. We offer this service.

What is CHAS

The Core Criteria and the threshold standard of CHAS and all the other SSIP accreditations  is as follows:

• Health & safety policy
• Competent Advice
• Training arrangements
• Monitoring, audit and review
• Workforce involvement
• Accident reporting and enforcement action
• Subcontracting/consulting
• Risk Assessments and Safe Systems of Work
• Cooperations with others
• Welfare provision
• Hazard elimination

The Good News

We are here to support you through the process; we can prepare all the documents, complete the registration forms, and simplify the process. CHAS is expensive, but other providers are very economical. The best thing to do is chat with us and learn more; we can tell you about the costs and the time frame. Our number is 0800 031 5404, or you can complete the form below.

CHAS deem to satisfy process

The CHAS Deem to Satisfy process (DtS) scheme allows contractors to apply for CHAS Standard membership without undergoing another health and safety assessment.

All member schemes listed on the SSIP forum adhere to the SSIP Core Criteria, backed by the Health and Safety Executive.

By mutually recognising each other’s schemes, suppliers benefit from only needing to complete one assessment, while buyers enjoy more efficient procurement processes. This approach reduces costs and has saved over £68 million since 2016.

Eligibility

Contractors must have already met the requirements of an assessment through another SSIP member scheme. 

Benefits

Contractors can save time and resources by avoiding a full assessment. They can also avoid paying full price for multiple accreditations. 

Process

Contractors can: 

1. Check if they have a qualification that CHAS recognises by contacting CHAS or using the e-form. 
2. Submit their assessment, which will be reviewed within 10 working days. 
3. Respond to any requests for additional information within the 2-week deadline. 

CHAS deem to satisfy registered members

Two-Way Deem to Satisfy between SSIP Registered Members.

Approval with a Registered Member can only be used to Deem to Satisfy with another Registered Member; it cannot be used to gain a Deem to Satisfy with a Certification Body Member.
