Can You Still Trade If Your Gas Interlock Has Failed?

Short answer? Usually, no.
If your gas interlock system has failed, most commercial kitchens are not legally permitted to continue trading until it’s repaired and fully operational.

Here’s what that means in practice and what to do next:

 

What Does a Gas Interlock Actually Do?

A gas interlock system is a safety device that prevents gas from flowing to cooking appliances unless the kitchen’s ventilation system is running correctly.

 

If the airflow drops, a sensor fault occurs, or the system fails:

• The gas valve closes
• Appliances won’t fire
• Your kitchen grinds to a halt

This isn’t a fault to “work around” it’s a legal safety requirement.

 

Can You Legally Keep Trading?

In most cases, no.

Environmental Health Officers (EHOs) expect:

• A working gas interlock system
• Linked to mechanical ventilation
• Tested and compliant

If your interlock has failed and you continue to trade:

• You risk immediate closure
• You may invalidate insurance
• You could face enforcement action

This applies across restaurants, takeaways, schools, care homes, and catering facilities throughout London, Kent, and Surrey.

 

Common Reasons Gas Interlocks Fail

We’re often called out for:

• Faulty airflow sensors
• Damaged or disconnected cabling
• Ventilation fans not proving airflow
• Incorrect original installation
• Systems bypassed during previous works

Sometimes the kitchen looks fine, but the interlock correctly detects a safety issue and shuts the gas off.

 

“Can We Bypass It Just for Today?”

This comes up a lot, especially during busy service.

The answer is no.
Bypassing or disabling a gas interlock:

• Is unsafe
• Is non-compliant
• Can lead to immediate closure if inspected

EHOs are particularly alert to this, and penalties can be severe.

What Should You Do If Your Gas Interlock Has Failed?

1. Stop using gas appliances
2. Do not attempt to override the system
3. Call a qualified commercial catering engineer
4. Get the fault diagnosed and repaired properly

In many cases, the issue can be resolved the same day, depending on access and parts.

Why PPM is a Must for London’s Commercial Kitchens

Operating in London’s fast-paced hospitality industry means even a minor equipment failure can disrupt your service flow and damage your reputation. Planned Preventative Maintenance (PPM) keeps kitchens running efficiently by identifying and fixing issues before they escalate, saving time, money, and stress.

 

1. Prevent Downtime to Protect Your Bottom Line

Emergency breakdowns aren’t just inconvenient, they’re costly. PPM enables regular inspections and servicing that catch wear and tear early, drastically reducing unexpected failures during peak hours.

 

2. Improve Energy Efficiency & Cut Operating Costs

Regular maintenance ensures appliances like gas ovens, combi steamers, and extraction systems are working at peak performance. A poorly calibrated oven or blocked ventilation system can lead to longer cook times and increased energy use. With PPM, airflow is optimised, burners operate efficiently, and equipment runs smoothly, reducing your energy bills and extending equipment life.

 

3. Extend Equipment Lifespan with Expert Care

PPM isn’t just maintenance, it’s investment protection. Regular lubrication, calibration, and cleaning ensure major appliances last longer, delaying costly replacements.

 

4. Stay Compliant & Enhance Workplace Safety

Health, safety, and fire safety regulations demand routine servicing of commercial kitchen equipment. With PPM, you get those all-important Gas Safety (CP42) and structural compliance checks to keep warranties valid and insurance valid.

 

5. Get Detailed Reports for Smarter Asset Management

Leading providers compile comprehensive condition reports after each visit. You receive a detailed asset list with ratings and recommendations, valuable for budgeting and long-term efficiency planning .

 

What’s Included in a Planned Preventative Maintenance (PPM) Contract?

 

• Initial Site Assessment – Engineers map out every appliance from ovens to refrigeration units.
• Tailored PPM Schedules – Depending on usage and equipment type, service frequency can range from 2–4 times per year.
• Hands-On Servicing During Visits:
  • Cooking & Gas: burners cleared, valves greased, pressure adjusted, gas tightness tested
  • Electrical Appliances: connections checked, safety and functionality tested
  • Ventilation/Hoods: cleaned to reduce grease fire risks, maintain airflow
  • Cleaning routines: filters, fryers, floors, all with detailed maintenance guidelines

 

Why London Kitchens Are the Perfect Fit for PPM

 

1. High Utilisation – Restaurants in London operate relentlessly. Scheduled PPM ensures continuous uptime and kitchen reliability.
2. Brand & Reputation Risk – Unexpected breakdowns lead to service delays and dissatisfied customers. PPM offers peace of mind.
3. Regulatory Pressure – With dense health and safety regulations, London kitchens must stay compliant. PPM keeps certification and standards up to date.

In the bustling culinary scene of London, where multi-chain restaurants strive to deliver consistent quality across multiple locations, the reliability of kitchen equipment is paramount. While addressing issues as they arise with ad-hoc repairs might seem cost-effective at first, this reactive approach can lead to unexpected downtime, mounting costs, and – perhaps most importantly – damage to your brand.

A commercial kitchen repair contract offers a proactive alternative, helping you stay ahead of faults, protect your reputation, and maintain smooth day-to-day operations across all your sites. 

 

1. Predictable Costs and Better Budgeting

Ad-hoc callouts often come with unexpected charges – especially during evenings, weekends or peak trading hours. A maintenance contract provides fixed costs, making it easier to plan and budget across your locations. Knowing exactly what you’ll be paying each month avoids nasty surprises and helps with long-term financial forecasting. 

 

2. Increased Equipment Lifespan

Just like a car, commercial kitchen equipment performs better and lasts longer when it’s regularly serviced. Preventative maintenance helps identify minor faults before they escalate into major breakdowns, reducing the need for costly replacements and extending the life of your ovens, refrigeration units, and other critical appliances. 

 

3. Reduced Downtime and Priority Response

Downtime in a commercial kitchen leads to delayed service, dissatisfied customers, and potential loss of revenue. With a service contract, you benefit from faster response times and scheduled maintenance visits – meaning less disruption and more reliability when it matters most. 

 

4. Compliance and Peace of Mind

Health & safety inspections can be stressful if your equipment hasn’t been checked in months. A regular maintenance plan ensures compliance with all relevant hygiene and safety regulations – giving you peace of mind that your kitchens are audit-ready at all times. 

 

5. Tailored Solutions for Your Business

Whether you’re operating one location or thirty, a repair contract can be designed around your specific setup. At RTC Technical Ltd, we build flexible agreements based on your kitchen layout, equipment usage, and trading patterns – so you get the cover that works for you. 

 

6. Centralised Reporting and Accountability

For larger groups, managing repairs across multiple sites can be a logistical headache. A service contract provides structured maintenance logs and central reporting, making it easy to track what’s been done, when, and where – ideal for group-wide compliance and performance reviews.

 

Work With RTC Technical Ltd 

At RTC Technical, we understand the unique pressures faced by hospitality businesses in London. That’s why we offer reliable, professional commercial kitchen repair contracts tailored to the needs of multi-site operators. Our qualified engineers work quickly, cleanly, and with minimal disruption – so your kitchens stay open and your customers stay happy.
