Day: 30 July 2025

  • Jack Murray
  • Detergents expert

For many businesses in the UK, the difference between commercial grade catering chemicals and detergents may not seem important.

However, in this guide we take a deep dive into the differences and why organisations should utilise professional chemicals for consistent performance, maximising hygiene, environmental considerations, reducing waste and convenience.

The importance of commercial chemicals and detergents

Commercial kitchens are significantly larger, busier and have more stringent hygiene and safety standards compared to a domestic kitchen. This means you should have chemicals that are capable of sufficiently cleaning a commercial kitchen whether it is rinse aid, potwasher, multi-surface cleaner or descaler.

Strength and concentration to ensure hygiene

Commercial kitchen chemicals and detergents are typically stronger and more concentrated to deal with the demands of a busy kitchen environment, such as larger volumes of washing and tougher grease deposits.

This is particularly critical in ensuring hygiene in commercial businesses like restaurants and the hospitality sector where domestic chemicals may be ineffective or require significantly higher volumes to achieve the same result.

More effective with larger warewashing equipment

Detergents work alongside your warewashing equipment to provide hygienic, clean and aesthetically pleasing results.

Commercial detergents are specialised for larger professional warewashing equipment, including dishwashers, potwashers, glasswashers and utensil washers, ensuring a more effective clean.

Household liquids and powders may simply be ineffective at cleaning tough and baked-on grease and grime along with the higher capacities associated with commercial warewashers.

Volumes, order quantities and logistics

Professional-grade detergents and chemicals are usually available in much larger quantities and volumes meaning they are more practical and less hassle for busy businesses.

JLA’s dishwasher liquids, for example, are available in 2x 5L bottles and 20L bottles with delivery to your site for reassurance. Domestic chemicals on the other hand are usually available in much smaller quantities causing unnecessary hassle.

Also, you can order at the most convenient time for you, with online purchasing via myJLA, available 24/7.

Advice and assistance

By purchasing from a supplier with experience working with businesses, like JLA, you can receive helpful advice, tips and assistance, which you cannot get from suppliers of household products.

Whether you are having issues with your detergents or are looking to improve cleaning processes, expert help from a supplier could help your business.

Reassurance and environmental standards

With businesses increasingly looking to become more sustainable, environmental accreditations and commitments are important to some businesses and their supply chains.

Both JLA and our chemical manufacturing partners are accredited to ISO 14001, providing our customers with the confidence that all raw materials and packaging are sourced sustainably, and that our products are designed to minimise environmental impact.

Auto-dosing systems

Automatic dispensers are available from suppliers for professional detergents, which are specifically designed to provide the optimum measure of detergent.

  • Reducing spills for health and safety and cost saving benefits.
  • Preventing overuse to save money and reduce excess suds in dishwashers and other warewashing equipment.
  • Strikes the balance between using insufficient volume resulting in poorly cleaned crockery, pots, and glasses yet avoiding over-use.
  • Predictable use so you can easily re-order chemicals.

If you require any assistance with your kitchen chemicals or detergents, then contact us today.

Is commercial fabric conditioner better than domestic?

  • 20th Jun 2025
Whether it’s hotels and spas needing soft towels, or care homes looking to improve their residents’ comfort, commercial fabric conditioner is a powerful tool in any commercial laundry setup. But what makes it work, and why is it a good idea to choose commercial-grade for your organisation? Here’s everything you need to know.
  • Giovanna Eaton
  • Compliance expert

Cleaning your commercial kitchen hoods and canopies is essential for safety, compliance and efficiency. But how often do they require cleaning, what are the regulations and what the tell-tale signs?

Tell-tale signs up a canopy requiring a clean

There are usually signs your canopy hood should be cleaned including the following.

Visible grease build-up
You shouldn’t ignore layers of grease on your cooker hood surfaces, filters, or ductwork. A heavy build-up won’t just reduce ventilation efficiency – it will increase the risk of fire and make your system non-compliant.

Lingering bad smells
Foul smells that hang around after service could mean grease and debris are trapped and decomposing in the system. At this point, only a professional clean will improve air quality.

Excessive smoke or poor airflow
If smoke isn’t clearing properly, or the kitchen feels too hot and humid, it’s likely that your hood airflow is being obstructed by grease-clogged ducts. A professional clean will restore the airflow to how it was before and ensure you remain compliant.

Noisy or weak fan performance
Unusual noises, weaker air suction, intermittent issues or a failure can stem from blades or ducts being clogged up with grease.

Increased pest activity
Rodents or insects will be attracted to grease deposits in ducting. Again, a fast response and deep cleaning will be needed to eliminate nesting sites and protect hygiene. Keeping your extractors clean can prevent this issue in the first place along with the headache and expense of a potential pest control issue.

What are the risks of not cleaning a cooker hood regularly?

Neglecting to clean your kitchen’s extractor system is likely to impact safety, compliance, and efficiency – not to mention your business’s reputation.

Increases the risk of fire
According to the National Fire Protection Association (NFPA), unclean extractor systems are the primary cause of restaurant fires, with even minor sparks igniting fires in grease.

Increases the risk of reputational damage, fines and closures
Non-compliance with TR19 and fire safety regulations can lead to fines or closures and will likely impact how your customers and staff view your business. You could even void your insurance coverage.

Increases the possibility of health issues
Poor air quality and bacterial build-up in an uncleaned ventilation system will quickly compromise air quality and could affect your staff’s health and wellbeing.

Increases your running costs
Blocked-up hoods will overwork your fans, reduce airflow and using more energy. In turn, you’ll spend more on bills, repairs and premature replacements.

Which regulations should I know about?

In the UK, kitchen extractor system cleaning is governed by both national regulations and specific industry guidelines.

Generally, though, your daily and weekly responsibilities should include cleaning filters and wiping clean filters and wipe surfaces to manage grease, and you should also arrange for certified technicians to assess your ductwork and fans quarterly or biannually.

Legally, you’re required to keep your kitchen safe and ventilated in line with the Health & Safety at Work Act 1974, as well as Workplace (Health, Safety and Welfare) Regulations 1992. Both ask you to maintain a safe environment, including mitigating fire risks from grease build-up, to protect your employees.

Fire Safety regulations also necessitate monthly to quarterly cleaning, depending on cooking methods and volume. Local councils may enforce their own rules, particularly if air quality issues or fire hazards are identified. And, of course, insurance providers often require proof of regular hood cleaning to validate your coverage.

Elsewhere, TR19 guidelines specify that kitchen extraction systems should undergo professional cleaning at least every six months, with more frequent cleaning for kitchens seeing heavy use.

What are the benefits of preventative maintenance for laundry equipment?

  • 20th Jun 2025
we explore the many benefits of preventative laundry equipment maintenance – and why it often pays off to hand over the work to a trusted commercial equipment specialist.
  • Andy Mills
  • HVAC expert

Whether it’s better heating performance or lower running costs, it always pays to look after your commercial boiler – even if you’ve only just had a new one installed.

In our latest guide, we look at ways you can extend the longevity and reliability of your system, covering everything from daily upkeep to preventative maintenance.

Back to basics: specification and installation

Before you can think about extending the lifespan of your commercial boiler, you’ll want the essentials in place. If you’re looking at a new boiler, this means sourcing a unit that’s suitable for your business, fully compliant, and ready for the future.

Choosing the right boiler is imperative for the longer-term health of your system. Go too small, and your boiler will struggle to produce the necessary heat and work too hard to last. Go too big, and you’re likely to waste energy and spend far more than you need to.

Installation is the other part of the puzzle. By law, all boilers must be installed and serviced by an experienced Gas Safe-accredited technician for your safety and peace of mind. So, make sure you choose an installation partner who can demonstrate this expertise – JLA has 450 in-house engineers with all the relevant qualifications.

Your commercial boiler should be installed in a well-ventilated, dry room so it can perform at its best. Your boiler engineer will make sure there’s sufficient clearance around it, and will also check that all pipework is well insulated for the winter months.

Regular monitoring and upkeep

Simple, regular maintenance shouldn’t feel like a chore, and is a great way to keep your commercial boiler operating reliably. Keeping an eye out for small issues as they emerge will also help you improve long-term performance, which should increase the boiler’s lifespan. Here are the main things to add to your rounds.

Flush the system
Over time, sludge and mineral deposits accumulate inside your boiler, causing corrosion. We recommend flushing the whole system to clear these deposits and help to improve overall efficiency.

Check the pressure
Boilers usually need to operate within a set pressure range (typically 1.0–1.5 bar). Too high or too low can stress the system and lead to disruptive downtime. If the system needs water adding to it, make sure to use the manufacturer’s instructions.

Bleed the radiators
By bleeding your radiators, you’ll remove trapped air from your system and make sure heated water fills the whole unit. In turn, you’ll reduce strain on the boiler, which means greater efficiency and safer operation.

Use your thermostats
Thermostats ensure you get the heating or hot water you need, when you need it – which is far better than constantly turning your boiler on and off again. This will minimise wear and tear, and save energy.

Run an idle boiler
During the warmer months, some organisations are much less likely to rely on their commercial boilers for heating. Prevent parts from seizing or gaskets from drying out by firing up the boiler on a semi-regular basis.

Short cycling
Turning a boiler on and off in short bursts can drastically accelerate wear on its critical components. Make sure you’re giving the system time to come online and warm up properly.

Professional servicing and maintenance

Prevention is always better than cure, which is why regular commercial boiler servicing and maintenance are vital for the long-term health of your boiler. For newer units, it might also be the only way to protect your guarantee.

A comprehensive service plan and audit will help you to spot and sort any problems while keeping you fully compliant with your legal obligations, such as your annual gas safety check and certification. Carried out by Gas Safe-registered engineers, JLA’s competitive maintenance plans include:

  • An annual service and gas safety check
  • Asset specific compliance certification (CP15)
  • Same/next day business hours response times
  • No call out charges
  • 24/7 helpline for faults or emergencies
  • A choice of 5 or 7 day a week contracts

Repairing faults or issues quickly

If your boiler develops a fault, such as unusual noises, a leak, or even differences in how it looks visually, you should contact an engineer for support as soon as possible.

Leaving it to chance is likely to affect the performance, reliability and lifespan of the system, and could even create a safety or compliance issue down the line.
