We help businesses keep kitchens safe and compliant. This short guide explains what a CP42 document covers and why it matters for commercial gas use. We write plainly — no jargon — so you can act with confidence.
The CP42 records checks on appliances, pipework, ventilation and extraction. It also covers gas interlock systems and emergency shut‑off valves. An engineer on the Gas Safe register must issue it and renew it every 12 months.
Restaurants, cafés, hotels and mobile catering need this paperwork to avoid fines, closure or voided insurance. Keeping the file current reduces risks from leaks, fire or carbon monoxide — and protects staff and guests.
We handle bookings, inspections and paperwork — so you get clear results and timely reminders. That way your business stays open and your team feels secure.

What the CP42 Gas Safety Inspection Covers in Commercial Kitchens
Our inspection walks through every gas appliance and system that keeps a commercial kitchen running smoothly. We focus on clear, practical checks so you can trust daily operation and stay compliant.
Gas appliances: condition, safe use and manufacturer parameters
We test each appliance against maker guidance. That includes settings, ignition and the flame picture. We note wear and overall condition.
Pipework and connections: integrity, leaks and corrosion checks
Pipework gets a tight visual and pressure check. We look for corrosion, loose fittings and any leak risk. Small faults are logged and explained on site.
Ventilation, extraction and interlock systems
Fans, hoods and ducting are measured for airflow. Extraction systems must clear fumes effectively. We also test interlock systems so gas only flows when ventilation works.

Emergency shut-off, boilers and cookers
We confirm emergency valves are accessible and operate correctly. Boiler checks cover flue sealing, CO readings and safe distances from open windows. Cookers and hobs are checked for ignition, leakage and reliable operation.
| Check | Purpose | Frequency | Who checks |
|---|---|---|---|
| Appliances | Safe use and condition | Annual | Gas Safe engineer |
| Pipework | Prevent leaks and corrosion | Annual | Gas Safe engineer |
| Ventilation & interlock | Ensure airflow before gas supply | Annual or after changes | Gas Safe engineer |
| Boiler & flue | CO safety and sealing | Annual | Gas Safe engineer |
After inspection, we record the condition of all systems and talk you through any findings. When everything meets the standard, the cp42 certificate is issued and should be kept on file for insurance and compliance.
Legal compliance, risks and insurance: staying safe and within the law
Keeping gas systems lawful and insured protects staff, customers and the future of your business. The Gas Safety (Installation and Use) Regulations 1998 require annual checks on commercial kitchens by a qualified, Gas Safe registered engineer. We help you meet those duties — clearly and reliably.
UK Gas Safety (Installation and Use) Regulations 1998 obligations
The law makes building owners and operators responsible for regular inspection, testing and safe installation. Annual checks must be logged and kept on file.
Consequences of non-compliance: fines, closure and criminal liability
Failing to follow regulations can lead to heavy fines, closure and prison in serious cases. Insurance claims may be denied if you lack a current gas safety certificate or safety certificate.
Minimising risks: leaks, fire, explosion and carbon monoxide exposure
Routine inspections spot leaks, faulty valves and blocked flues before they become dangerous. Early fixes reduce downtime and protect people on site.
Insurance validity: why a current CP42 gas safety certificate matters
Many insurers insist on a current cp42 certificate to keep cover valid. We schedule checks, use Gas Safe engineers and provide tidy paperwork — so your insurer, EHO and team can trust the record.
- Simple scheduling — we arrange visits at times that suit your service.
- Trusted engineers — commercial specialists who follow regulations and note issues clearly.
- Clear records — safety certificate kept where insurers and inspectors can find it fast.

FAQ
CP42 Certificate: What you need to know
The CP42 document records a safety inspection for commercial gas installations — commonly used in restaurants, cafés and other catering businesses. We check appliances, pipework, ventilation and safety devices, then issue the report to confirm condition and any actions needed. Keeping this up to date helps protect staff, customers and premises.
what is a cp42 certificate
The CP42 is a formal gas safety report for commercial kitchens. A Gas Safe registered engineer inspects catering equipment, extraction systems and related pipework. If everything meets safety standards, the engineer signs and issues the report — if not, they list defects and recommend repairs before safe use.
What the inspection covers — appliances and manufacturer parameters
We test gas cookers, hobs, fryers, boilers and other equipment for safe operation and compliance with manufacturer guidance. That includes checking ignition, flame stability and carbon monoxide risks so appliances perform safely during daily service.
What the inspection covers — pipework and connections
We examine supply pipework and fittings for leaks, corrosion and mechanical damage. Tightness testing and visual checks confirm integrity so gas cannot escape and create a hazard.
What the inspection covers — ventilation and extraction systems
Adequate ventilation and extraction are vital. We assess airflow, hoods, filters and ducting to ensure fume removal meets safety and hygiene standards and prevents build-up of combustion gases.
What the inspection covers — gas interlock systems
Where fitted, we test interlocks that stop gas flow unless ventilation is working. These systems protect staff by preventing fuel being supplied when extraction is off or malfunctioning.
What the inspection covers — emergency shut-off and safety devices
We confirm emergency valves, isolation points and safety cut-outs are in the right place and operate correctly. Clear labelling and easy access are part of the inspection.
What the inspection covers — boiler-specific checks
Boilers get flue condition checks, combustion analysis and distance assessments from openings and windows. We verify safe flue seals and efficient combustion to reduce carbon monoxide risk.
What the inspection covers — cookers and hobs
We test ignition systems, run leakage checks and assess operational safety under real conditions. Any faulty valves or controls are recorded and require attention before signing off.
Legal compliance, risks and insurance — obligations under UK law
The UK Gas Safety (Installation and Use) Regulations 1998 set duties for anyone responsible for commercial gas installations. Regular inspections by Gas Safe registered engineers keep you compliant and reduce legal exposure.
Legal compliance, risks and insurance — consequences of non-compliance
Failure to maintain gas safety can lead to enforcement notices, business closure, heavy fines and even criminal charges if negligence causes harm. Insurance may be void without proper documented inspections.
Legal compliance, risks and insurance — reducing risks
Routine inspections and timely repairs reduce the chance of leaks, fire, explosion and carbon monoxide exposure. Staff training and clear emergency procedures also minimise harm.
