CP42 Commercial Kitchen Gas Safety Certificate

What is a commercial kitchen CP42 Gas Safety Certificate?

This is the official term for a safety certificate that is issued annually by a registered Gas Safe engineer to cover all gas installation and appliances in your kitchen. These certificates specifically target commercial kitchen facilities. Typically these include:

• Restaurants & Cafes
• Take-away shops
• Catering businesses
• Staff canteens
• Food production centres

Do I need a CP42 Gas Safety Certificate?

Yes, if you have a commercial kitchen with gas appliances. You have legal duty to ensure sure that any gas equipment on your premises is checked and certified by a gas safe qualified engineer at least once every year. Your insurance cover will almost certainly depend on you having a current CP42 Gas Safety Certificate

If you lease your property, don’t assume this is the responsibility of the Landlord. Usually leases include clauses that pass responsibility for gas safety to the leaseholder.

Understanding Legionella Risk Assessments

A Legionella risk assessment is a critical process designed to identify and evaluate the risks associated with the presence of Legionella bacteria in water systems. Legionella is a type of bacteria that can cause Legionnaires’ disease, a severe form of pneumonia, and Pontiac fever, a flu-like illness. These bacteria thrive in warm water environments, particularly between 20°C and 45°C, which makes buildings with water systems, cooling towers, and plumbing networks vulnerable to outbreaks. As such, a Legionella risk assessment is essential for businesses, healthcare settings, and public buildings to ensure the safety of occupants and comply with legal health and safety standards.

What Is a Legionella Risk Assessment?

A Legionella risk assessment is a systematic evaluation of the water systems within a building or facility to identify any conditions that may encourage the growth and spread of Legionella bacteria. This process typically involves:

• Identifying water systems: Any water systems in the building, including cooling towers, hot and cold water systems, air conditioning units, and other water-related infrastructure, are assessed.
• Evaluating the risk factors: Factors that could promote Legionella growth, such as temperature, water stagnation, and organic material in the water, are identified.
• Control measures: Existing control measures, such as water treatment or regular cleaning routines, are reviewed to ensure they are sufficient to mitigate the risks.

The ultimate goal of the Legionella risk assessment is to implement preventive measures to ensure that the water systems are free from Legionella contamination and do not pose a risk to the health of individuals in the building.

Why Is a Legionella Risk Assessment Important?

Legionella bacteria can grow and multiply in water systems if the conditions are right. Inhalation of small droplets of water containing the bacteria can lead to Legionnaires’ disease, which is fatal in some cases. Individuals most at risk include the elderly, those with weakened immune systems, and people with chronic respiratory conditions. A Legionella risk assessment is vital because:

• Health and Safety Compliance: Under the Health and Safety at Work Act 1974 and the Control of Substances Hazardous to Health (COSHH) Regulations, building owners and employers are legally obligated to assess and control the risk of Legionella. See further information legislation at the HSE website.
• Public Safety: Outbreaks of Legionnaires’ disease can be devastating to the affected individuals and costly for organisations in terms of legal fees, fines, and reputational damage. Regular risk assessments help minimise these risks.
• Prevention of Outbreaks: A thorough Legionella risk assessment ensures that measures are in place to prevent the bacteria from thriving, significantly lowering the likelihood of an outbreak.

The Process of Conducting a Legionella Risk Assessment

The Legionella risk assessment process typically involves the following steps:

1. Surveying the Water Systems: An assessment starts with a detailed survey of the building’s water systems. This includes identifying all sources of water, such as hot and cold-water tanks, cooling towers, and fountains. The assessor examines the design and maintenance of these systems to understand the potential for Legionella growth.
2. Identifying Potential Hazards: Various factors can increase the likelihood of Legionella contamination. These include stagnant water, temperatures conducive to bacteria growth (between 20°C and 45°C), and the presence of biofilm or organic material that may nourish the bacteria.
3. Risk Evaluation: After identifying hazards, the risk is evaluated based on the likelihood of contamination occurring and the potential consequences of an outbreak. This involves considering factors such as water temperatures, system cleanliness, maintenance schedules, and the age and condition of the plumbing.
4. Control Measures and Recommendations: The Legionella risk assessment should outline control measures to reduce the risk of Legionella growth. These measures can include temperature control (ensuring hot water systems are maintained above 60°C), regular cleaning and descaling of water systems, and the installation of water treatment systems like biocides or UV sterilisation.
5. Documentation and Monitoring: The results of the Legionella risk assessment, along with recommendations for preventive measures, should be documented. Ongoing monitoring and regular updates to the risk assessment are necessary to ensure that the control measures are effective and the risk remains low.

Key Control Measures for Legionella Prevention

Several practical steps can be taken to control Legionella risks in water systems. Some of the key control measures include:

• Temperature Management: Maintain hot water systems at temperatures above 60°C and cold water systems below 20°C to limit the growth of Legionella.
• Water System Maintenance: Regular cleaning, flushing, and descaling of water systems can prevent the build-up of organic matter and biofilms that harbour bacteria.
• Regular Monitoring: Routine water testing for Legionella bacteria, as well as monitoring temperature and system performance, helps to ensure compliance with safety standards.
• Water Treatment Systems: The use of biocides or UV systems to kill or prevent bacterial growth can be an essential part of a comprehensive control strategy.

Legal Requirements for Legionella Risk Assessments

Under UK law, businesses and employers are required to comply with the Health and Safety Executive (HSE) guidelines for controlling Legionella risks. The “Approved Code of Practice L8” outlines the legal responsibilities of employers to carry out a Legionella risk assessment. Non-compliance with these regulations can result in heavy fines, legal consequences, and harm to individuals’ health.

Conclusion

Legionella risk assessments are a fundamental part of ensuring the safety and health of those using any building with water systems. By identifying potential risks and implementing effective control measures, organisations can prevent the growth and spread of Legionella bacteria, protecting both individuals and their legal obligations. Regular assessments and prompt action are essential to maintaining a safe environment and preventing outbreaks of Legionnaires’ disease.

What are the minimum building maintenance requirements to stay within the law?

Our clients often ask this question.

We think this largely stems from recent high profile cases where employees have been held personally libel for failings and have not been able to hide under a corporate umbrella.

Also, the small print in many insurance policies is getting more and more particular about some of these things. Looking on the web, there is no up to date summary of the building maintenance requirements, so I thought I would write one myself.

Based on our interpretation of the law, these are maintenance activities that are required to stay within the law.

Air Conditioning – EU F-gas Regulation No. 842/2006

You must have an air conditioning maintenance plan in place. Frequency depends on weight of refrigerant.

• every 12 months (for buildings over 3 kg refrigerant – usually shops with 1-15 air conditioning units)
• every 6 months (for buildings over 30kg refrigerant – usually larger buildings with more than 15-75 air conditioning units)
• every 3 months (for buildings over 300kg refrigerant – very large office buildings with more than 75 air conditioning units)

Gas Equipment – Gas Safety (Installation and Use) Regulations 1998

All commercial gas appliances most inspected and certified at least annually. You must hold a valid gas safety certificate issued by a GasSafe registered engineer. The regulation states that gas appliances must be maintained and serviced in line with the manufacturers recommendations. In many cases, particularly with larger equipment, this will be more frequently than annually.

Water/ Legionella – Health and Safety at Work Act 1974

Firstly, a valid Legionella Risk Assessment most be in place and these are valid for 2 years. Normally monthly testing of water temperatures would be required.

Emergency Lights – The Regulatory Reform (Fire Safety) Order 2005

System must undergo 3hr drain down of emergency light batteries on an annual basis after which a level of 1.0 lux, is required at floor level for defined escape routes. Monthly switch on tests are also recommended.

Fire Systems – The Regulatory Reform (Fire Safety) Order 2005

A Fire Risk Assessment must exist and be reviewed at regular intervals, we interpret this as annually. A ‘responsible person’ should be identified and suitably trained. All Automatic fire detection systems are required to be tested and  maintained (at least annually). Record keeping of service visits / inspections and weekly “Bell testing” should be kept.

Lifts – The Lifting operations & lifting equipment reg’s 1998 (LOLER) Regulation 9.

All lifts provided for use in work activities are thoroughly examined by a competent person at regular intervals. Typically lifts are maintained quarterly.

Lightning Conductors – Section 5 of Electricity at Work Act 1989

All lightning conductors and earth grounding installations should be visually inspected and tested at regularly fixed intervals, preferably not exceeding 12 months.The testing is carried out to BS 6651.

 

 

What is R22 Refrigerant and Why You Must Act Now

If your home, shop, or business still relies on an older air conditioning or refrigeration system, there’s a good chance it runs on R22 refrigerant. While once a standard refrigerant in the UK, R22 has since been banned due to its harmful effects on the environment. In this guide, we’ll explain what R22 is, why it’s no longer legal, and what your options are if your system still depends on it. Dept. Environment Sheet RAC 8

What Is R22 Refrigerant?

R22—formally known as HCFC-22 (hydrochlorofluorocarbon-22)—is a chemical refrigerant that was widely used in air conditioning and refrigeration systems installed before 2010. It was once praised for its efficiency and safety profile compared to older refrigerants like R12. R22 works by absorbing heat from one area and releasing it in another, making it ideal for keeping spaces cool and comfortable.

Why Was R22 Refrigerant Phased Out?

Despite its practical benefits, R22 has a serious downside: it damages the ozone layer. As an HCFC, R22 contains chlorine atoms which, when released into the atmosphere, break down ozone molecules. The ozone layer is vital for shielding the Earth from harmful ultraviolet (UV) radiation. Its depletion has led to increased health risks such as skin cancer and eye damage, as well as negative effects on wildlife and ecosystems.

The global environmental community responded with the Montreal Protocol, an international treaty designed to phase out substances that harm the ozone layer—including R22 refrigerant.

---

Key Dates in the R22 Phase-Out (UK & EU)

• 2010: The sale of new R22 equipment was banned in the UK and across the European Union. However, recycled R22 could still be used for servicing.

• 2015: The use of all R22 refrigerant, including reclaimed or recycled refrigerant, was completely outlawed in the UK. Systems using R22 could still operate, but could no longer be legally serviced if refrigerant was needed.

• 2020 and Beyond: The global phase-out continues, with stricter environmental legislation and increased pressure to replace outdated systems.

---

How Do I Know If My System Uses R22?

If your air conditioning or refrigeration system was installed before 2010, it’s likely to contain R22 refrigerant. You can usually confirm this by checking the manufacturer’s label or rating plate on the outdoor unit. It may list the refrigerant type as:

• R22

• HCFC-22

• Chlorodifluoromethane

Still unsure? A professional engineer can inspect your system and confirm the refrigerant type.

---

What Happens If I Keep Using an R22 System?

Although operating an existing R22 system is not illegal, continuing to do so carries several significant risks:

1. Unserviceable Equipment

If your system develops a leak or refrigerant-related fault, it cannot be legally repaired using R22. This could leave your cooling system inoperable, especially during peak usage periods.

2. High Operating Costs

Older systems are often far less energy-efficient than modern alternatives. This means higher electricity bills and a larger carbon footprint.

3. Spare Parts Are Becoming Obsolete

Finding replacement components for ageing systems is becoming increasingly difficult and expensive.

4. Insurance and Compliance Risks

Depending on your building’s use (especially in commercial or public settings), continuing to operate an outdated system could put you at odds with insurance or regulatory standards.

---

What Are My Options?

Now that R22 is no longer legally supported, you’ll need to consider one of the following options:

Option 1: Do Nothing

You could continue using your existing system until it fails. However, this approach carries a serious risk. Once it breaks down, repairs involving refrigerant are not legally permitted, potentially leaving you without cooling for days or even weeks.

Option 2: Retrofit Your System

In some cases, older systems can be adapted to work with a modern refrigerant. This involves flushing the system, changing the oil, and replacing certain components like the expansion valve or compressor.

Advantages:

• Cheaper than full replacement

• Quicker turnaround

Disadvantages:

• Not all systems are compatible

• Energy efficiency may not improve significantly

• Still based on outdated technology

Option 3: Replace the System

The most future-proof and environmentally responsible option is to replace your old system entirely with a new one designed for modern refrigerants like R410A or R32.

Advantages:

• Up to 50% more energy-efficient

• Quieter and more reliable

• Better temperature control

• Fully compliant with current regulations

• Lower environmental impact

Though the upfront cost can be higher, long-term savings on energy bills and reduced maintenance often make this the most cost-effective solution.

---

Financial Benefits of Upgrading

• Energy Efficiency: Modern systems use less electricity to achieve better performance, which can lead to significant savings over time.

• Tax Relief and Incentives: Certain commercial systems may qualify for capital allowances or government-backed energy efficiency schemes.

• Increased Property Value: Upgrading your HVAC system can enhance your property’s appeal and future-proof your investment.

---

Legal and Environmental Responsibilities

Continuing to operate an R22 system doesn’t just pose operational risks—it also raises environmental concerns. Businesses especially have a responsibility to ensure their buildings meet environmental compliance standards. Non-compliance can affect reputation, customer trust, and even result in penalties.

If your system leaks, not only can it no longer be serviced legally, but the leak itself may be in breach of environmental regulations due to the emission of harmful gases.

---

Why Upgrade Now?

Waiting until your R22 system fails will only increase costs, downtime, and inconvenience. Replacing your system proactively:

• Gives you time to explore options

• Allows for a smooth, planned transition

• Reduces the risk of emergency breakdowns

• Lets you take advantage of seasonal promotions or government incentives

Do I need a Commercial Gas Safety Certificate?

It is very simple, if you have a commercial property with gas appliances, it is a criminal offence not to have a valid annual Gas Safety Certificate. We issue these whenever we complete a gas boiler service, so this is the best way to get them.

How to Get a Gas Safety Certificate?

Contact us with a list of your gas fired boilers or heaters and we will provide a quote within 24hrs. You could have your gas safety certificate and boilers serviced within a few days. Phone numbers at the top of the page

What are the regulations?

About 30 people die every year in the UK through poorly installed or badly maintained gas appliances and flues resulting in deadly carbon monoxide poisoning. The Gas Safety (Installation and Use) Regulations 1998 impose duties on users of gas systems to ensure they are safe and suitable for use. Full detals can be found at the Government Gas Safety Regulations webpage.

These duties would include being responsible for the annual servicing and inspection of all in-service gas boilers, fires, heaters and any other type of gas burning equipment or appliance. Whether you are a tenant or a landlord, employers or self-employed, if you are responsible for gas appliances, this applies to you.

Your lease or a separate contractual agreement can help to set out practical arrangements for ensuring gas safety requirements are met. However, the ultimate legal responsibility remains with the occupier of the workplace concerned.

The owner, or other person in control of the building, may also have duties under the Health and Safety at Work Act 1974 – such as ensuring heating equipment in common parts is maintained safely. The lease or separate contractual agreement can be used to determine how these responsibilities are allocated.

Whatever the size of the appliance, type or location of the appliances and systems, it is mandatory to ensure that they are serviced at least annually, or as often in accordance with manufacturer’s specifications.

What if I don’t have a Gas Safety Certificate?

In our view, it is simply not worth the risks associated with not having a Gas Safety Certificate. It’s not just the penalty fines or loss of supply; it’s the risks to life of faulty equipment and potential imprisonment if you are responsible.
Severe penalties for non-compliance can be imposed and deaths could result in manslaughter charges for landlords and agents. Non compliance is a criminal offence and courts can impose unlimited fines and custodial sentences. This may also invalidate your property insurance and could subsequently lead to claims for civil damages – awards in these cases have proved to be very high indeed.

How Much Will A Gas Safety Certificate Cost?

This varies according to the number and type of gas appliances you have. The best and most cost effective time to get a gas certificate is part of your annual maintenance.

What Does A Gas Safety Certificate Involve?

Gas Safety Certificates can only be issued by GasSafe registered engineers. They will need to attend your premises and carry out a series of tests on each gas appliance, including a visual inspection, functionality, pressure and operation tests. Any appliance that uses an extraction system to remove combustion gases will also undergo inspection to assess the extraction method is suitability or not.  Appliances that are being tested will need to be isolated for a short period of time until certain tests are completed.

I have just installed a new gas appliance, do I need a certificate?

After a Gas Safe registered engineer has fitted or serviced your gas appliance, they will often leave you with a report which explains what checks they did. This report may be issued as a gas safety record, sometimes referred to as a gas safety certificate depending on the job you have asked them to do. It isn’t always a legal requirement for your engineer to give you this type of information, but many Gas Safe registered engineers will provide it or similar.

The gas safety information tells you that the gas appliance or gas fitting has been checked to see if it is working safely and meets the correct safety standards. This information may also tell you when you next need to service the appliance.

I am a landlord, what are my responsibilities?

If, under your lease, the landlord retains responsibility for gas appliances, a copy of the Gas Safety Certificate must be given to the tenant on entry and within 28 days of an annual check. A copy must also be retained by the landlord for 2 years.

By law, landlords must have all gas appliances serviced regularly, normally once a year by a Gas Safe registered engineer. The Gas Safe registered engineer will provide a Gas Safety record upon completion of the check.

If you use a managing agent make sure the contract makes it clear who is responsible for managing gas safety checks.

What information does the Gas Safety record contain?

As a minimum, the record of a gas safety check must contain:

• description and location of each appliance and/or flue checked
• name, registration number and signature of the engineer who carried out the check
• date on which the appliance and/or flue was checked
• the address of the property at which the appliance and/or flue is installed
• the name and address of the landlord (or his agent where appropriate)
• any defect identified and any action required or taken to fix it
• confirmation of the results of operational safety checks carried out on the
