CP7 and CP47 Gas Safety Inspections UK

If you use gas equipment in your workplace, regular safety inspections aren’t just good practice, they’re often a legal requirement. CP7 and CP47 gas inspections help ensure your equipment is safe, compliant and operating correctly, protecting both your staff and your business.

What is a CP7 Gas Inspection?

A CP7 gas inspection is a formal safety inspection certificate for industrial and commercial gas equipment. It confirms that gas systems such as cylinders, regulators, hoses, flashback arrestors and associated equipment are safe to use and comply with UK regulations.

CP7 inspections are commonly required for workshops, fabrication facilities, factories and engineering environments where gas equipment is used regularly.

What is a CP47 Gas Inspection?

A CP47 gas inspection is specifically designed for mobile or portable gas equipment, most commonly used in environments such as:

• Construction sites
• Maintenance operations
• Facilities management
• Mobile welding or cutting setups

The CP47 certificate confirms that portable gas equipment is safe, correctly set up and compliant for use in the field.

What’s the Difference Between CP7 and CP47?

The main difference is the type of equipment and working environment being inspected.

• CP7 → Fixed or workshop-based gas equipment
• CP47 → Portable or site-based gas equipment

Both inspections assess safety, condition and compliance - they simply apply to different use cases.

Do I Need a CP7 or CP47 Gas Inspection?

If your business uses compressed gas equipment, regulators or oxy-fuel systems, it is a legal requirement to have an annual, documented inspection by a trained inspector.

Many companies require these certificates for:

• Insurance compliance
• Health and safety audits
• Site access permissions
• Contractor approval schemes
• Legal duty of care under UK safety regulations

Failure to provide these certificates could result in fire and explosion claims being denied, employers’ liability coverage being affected and invalidated policies in the event of an accident.

If you’re unsure which certificate you need, contact us and our inspector can advise based on your equipment and working environment.

How Often is a CP7 / CP47 Gas Inspection Required?

Most businesses arrange inspections annually (every 12 months).

However, inspections may be required more frequently depending on:

• Insurance requirements
• Site rules or contractor agreements
• Equipment usage levels
• Risk assessments

Annual inspections are considered best practice across the UK.

What Does a Gas Safety Check Involve in the UK?

A CP7 or CP47 inspection typically includes:

• Visual inspection of cylinders, regulators, hoses, and fittings
• Leak detection testing
• Condition and wear assessment
• Flashback arrestor testing
• Pressure and functionality checks
• Compliance with current UK safety standards
• Identification of any risks or non-conformities

Once complete, you’ll receive certification showing whether the equipment has passed.

What Can Fail a Gas Safety Check?

Equipment may fail if any safety concerns are identified, such as:

• Damaged or perished hoses
• Faulty regulators or gauges
• Gas leaks
• Missing or defective flashback arrestors
• Incorrect fittings or unsafe setup
• Equipment outside of service life
• General wear that creates a safety risk

Failing equipment does not necessarily mean it cannot be repaired.

What Happens if My Equipment Fails the Inspection or is Unsafe?

In most cases, any issues identified during the inspection can be resolved on the same visit, allowing the equipment to be retested and certified without delay. Our inspectors carry a comprehensive range of replacement parts and equipment, which helps avoid the need for a second appointment wherever possible.

If immediate repair isn’t possible, we’ll clearly explain what’s required to bring your equipment up to standard and help you arrange the necessary solution.

What Will the Inspector Need From Me?

Our inspector will simply require access to your gas equipment and a safe working environment to carry out the inspection. A risk assessment will be completed on arrival, but we do ask that you inform us in advance of any specific site safety requirements or procedures.

You (or a responsible representative) should also be available once the inspection is complete so we can review the results together and discuss any recommendations if needed.
