Core of Knowledge Training for Laser & IPL: The Complete UK Guide
If you work with lasers or IPL, you have probably heard the term Core of Knowledge training.
It is something that comes up regularly when setting up a new laser clinic, applying for a Special Treatment Licence, preparing for a council inspection or simply making sure your clinic has the correct training and safety documentation in place.
But what exactly is a Core of Knowledge course?
Who needs one?
Is Core of Knowledge the same as a laser qualification?
And if you have completed your Core of Knowledge training, do you still need a Laser Protection Adviser (LPA)?
These are all questions I get asked regularly, so I wanted to put together a straightforward guide explaining what Core of Knowledge training is, what it covers and how it fits into the wider laser safety requirements for clinics in the UK.
If you are specifically looking for an online Laser & IPL Core of Knowledge course, you can find details of my course here:

What is Core of Knowledge training?
Core of Knowledge training is essentially laser and optical radiation safety training.
The purpose is to make sure people working with laser and IPL equipment understand the potential hazards involved and the safety measures required to work with these systems safely.
The BMLA has a specific Core of Knowledge syllabus for staff working with lasers and other relevant light sources in medical, surgical, dental and aesthetic environments.
You can view the BMLA Core of Knowledge information here:
https://bmla.co.uk/core-of-knowledge-syllabus/
The MHRA also provides guidance on the safe use of lasers, intense light source systems and LEDs in medical, surgical, dental and aesthetic practices:
It is important to understand that Core of Knowledge training is primarily safety training.
It is not designed to teach you how to carry out a specific laser treatment or how to operate one particular manufacturer's machine.
That is where treatment-specific and manufacturer training come in.
Who needs Core of Knowledge training?
Core of Knowledge training can be relevant to anyone working with or around laser and IPL equipment, particularly those working with Class 3B and Class 4 laser systems.
This can include:
Aesthetic practitioners
Laser technicians
IPL practitioners
Laser and IPL operators
Nurses
Doctors
Dentists
Clinic owners
Clinic managers
Laser Protection Supervisors
Beauty professionals
Staff working with Class 3B and Class 4 lasers
The exact requirements can vary depending on the equipment being used, the role of the person using it, the local authority, licensing conditions, insurance requirements and the type of clinic.
This is why I would always recommend checking the requirements that apply to your particular clinic rather than assuming that one qualification or certificate covers everything.
Is Core of Knowledge the same as a laser qualification?
No, and this is something that is often misunderstood.
Core of Knowledge training is about laser safety and understanding the hazards associated with laser and IPL equipment.
A treatment qualification is different.
For example, if you purchase a diode laser for hair removal, the manufacturer may provide training on how to use that particular machine. This may cover treatment protocols, settings, contraindications, patient preparation and aftercare.
That training is important, but it does not necessarily provide the same level of laser safety knowledge as a dedicated Core of Knowledge course.
Equally, completing a Core of Knowledge course does not mean that you are automatically qualified or competent to carry out a particular treatment.
You need to think of these as separate parts of your overall training.
Core of Knowledge = laser and IPL safety
Treatment training = how to safely and competently perform the treatment
Manufacturer training = how to use your particular device
All three can be important depending on your role and the equipment you are using.
What does a Core of Knowledge course cover?
A good Core of Knowledge course should cover the fundamental safety principles behind lasers and IPL.
This includes understanding how laser and IPL systems work, what makes them potentially hazardous and how those hazards can be controlled.
Laser and IPL physics
You will generally cover topics such as:
Wavelength
Energy
Power
Fluence
Pulse duration
Repetition rate
Spot size
Laser generation
Monochromaticity
Coherence
Collimation
Beam characteristics
You do not need to be a physicist to understand these principles, but having a good understanding of them is important when it comes to understanding laser safety.
Laser classifications
Laser classification is another important part of Core of Knowledge training.
You should understand the different laser classifications and the potential hazards associated with them.
In aesthetic clinics, you will commonly come across Class 3B and Class 4 lasers, which require appropriate safety controls.
Understanding the classification of your equipment is important when considering things such as controlled areas, protective eyewear, signage and operating procedures.
Eye and skin hazards
Laser radiation can cause serious injury to the eyes and skin if appropriate controls are not in place.
The level of risk depends on factors such as the wavelength, power, exposure time and type of laser being used.
This is why laser safety should never be treated as simply putting on a pair of goggles and getting on with the treatment.
There needs to be a wider safety system around the equipment.
Laser tissue interaction
Core of Knowledge training also looks at what happens when light interacts with tissue.
This includes:
Absorption
Reflection
Transmission
Scattering
Chromophores
Thermal effects
Selective photothermolysis
Thermal relaxation time
Understanding these principles helps practitioners understand why different wavelengths and treatment parameters produce different effects within the skin.
Protective eyewear
Suitable laser safety eyewear is one of the most important pieces of PPE when working with lasers.
However, you cannot simply buy a pair of goggles because they say "laser safety" on them.
The eyewear needs to be appropriate for the equipment you are actually using.
This means considering the wavelength or wavelengths, optical density and the potential exposure.
If you are unsure what eyewear you require for your laser, this is something your LPA should be able to advise you on.
Controlled areas
Higher-risk laser systems require appropriate control of the treatment area.
This can include restricting access to the room, appropriate warning signs, controlling who is permitted to enter and making sure the correct procedures are followed while the laser is operating.
Your Local Rules should set out how this is managed within your particular clinic.
Risk assessments
Laser and IPL risk assessments are another important part of laser safety.
Your risk assessment should look at the actual equipment being used, the room where it is operated, who may be exposed and what control measures are required.
This is why I would always recommend having a site-specific assessment rather than relying on a generic laser risk assessment downloaded from the internet.
Every clinic is different and every laser installation is different.
Local Rules
Local Rules are an important part of your laser safety documentation.
They provide the framework for how the laser or IPL equipment should be operated safely within your clinic.
They can cover things such as:
Who is authorised to use the equipment
Controlled areas
Protective eyewear
Warning signs
Access arrangements
Safe operating procedures
Emergency procedures
Responsibilities of staff
Incident procedures
Equipment details
Your Local Rules should be relevant to your actual clinic and equipment.
This is one of the areas where Core of Knowledge training and the work of an LPA link together.
What does a Laser Protection Adviser actually do?
A Laser Protection Adviser, or LPA, provides specialist advice on laser safety.
If you are opening a new laser clinic or purchasing a laser or IPL machine, an LPA can help you make sure the equipment and treatment environment are set up appropriately.
Depending on your circumstances, this can include:
Laser and IPL risk assessments
Local Rules
Site audits
Controlled area advice
Laser safety eyewear advice
Warning signage
Equipment documentation
Laser safety procedures
Staff safety arrangements
Special Treatment Licence requirements
Preparation for council inspections
Ongoing laser safety advice
If you are looking for a Laser Protection Adviser in London, or an LPA elsewhere in the UK, you can find out more about my services here:
https://www.laserprotectionadvisers.co.uk/
Do I still need an LPA if I have completed Core of Knowledge?
Yes, completing a Core of Knowledge course does not make you a Laser Protection Adviser.
These are two different things.
Your Core of Knowledge training gives you the knowledge to understand the safety principles involved in working with lasers and IPL.
An LPA provides specialist advice on your particular equipment and premises.
For example, your LPA may assess your treatment room, complete your risk assessment, prepare your Local Rules, advise on eyewear and controlled areas and identify anything that needs to be addressed before your clinic starts operating.
Think of it as two separate parts of the same safety system.
Staff need appropriate training.
The clinic needs appropriate safety documentation and controls.
The equipment and premises need to be assessed appropriately.
What is the difference between an LPA and an LPS?
Another question I am often asked is the difference between a Laser Protection Adviser (LPA) and a Laser Protection Supervisor (LPS).
They are not the same role.
An LPA provides specialist laser safety advice to the clinic.
An LPS is usually someone within the clinic who has responsibility for helping to make sure the Local Rules and safety procedures are followed on a day-to-day basis.
The LPS may be responsible for things such as:
Making sure staff follow the Local Rules
Checking safety procedures are being followed
Raising safety concerns
Supporting authorised users
Maintaining relevant records
Liaising with the LPA
The LPS may therefore benefit from Core of Knowledge training, but completing a Core of Knowledge course does not automatically make someone an LPS either.
Does my laser clinic need Core of Knowledge training?
This is where things can become slightly confusing because there is not one single requirement that applies identically to every laser and IPL clinic in the UK.
Requirements can vary depending on:
Your local authority
The type of treatment you provide
The equipment you use
The classification of the laser
Your role
Licensing requirements
Insurance requirements
Employer requirements
Some councils specifically request evidence of laser safety training or Core of Knowledge training as part of their licensing or inspection requirements.
If you are setting up a clinic, I would always recommend checking with your local authority before assuming that your existing qualifications will be sufficient.
Core of Knowledge and Special Treatment Licences
If you are opening a laser or IPL clinic, you may also need to apply for a Special Treatment Licence.
This is particularly relevant in London, where each borough has its own licensing arrangements.
The exact requirements can therefore vary from one council to another.
Depending on the council and your circumstances, you may be asked for documentation relating to:
Staff qualifications
Laser safety training
Core of Knowledge
Laser risk assessments
Local Rules
LPA involvement
Laser safety eyewear
Treatment protocols
Equipment information
Safety procedures
This is one of the reasons I recommend getting your laser safety arrangements sorted before submitting your licence application rather than waiting for the council to ask for missing documents.
If you are looking for information about laser licensing in London, I have written a separate guide here:
I also have a guide specifically covering what London laser clinics should have in place before an inspection:
What should you look for when choosing a Core of Knowledge course?
There are now a number of laser safety and Core of Knowledge courses available, particularly online.
If you are looking for a Core of Knowledge course UK, I would recommend checking exactly what is included rather than simply choosing the cheapest course.
Things I would look at include:
Does it follow the appropriate Core of Knowledge syllabus?
Check what the course actually covers and whether it is based on the relevant syllabus.
Is it suitable for laser and IPL?
If you work with IPL as well as laser, make sure the course covers the relevant safety principles for both.
Is it UK focused?
If you are working in a UK clinic, UK guidance and UK licensing considerations are obviously important.
Is it LPA reviewed?
It is worth checking who has developed or reviewed the course content and what their qualifications and experience are.
Is it BMLA approved?
The BMLA maintains a list of approved Core of Knowledge courses:
https://bmla.co.uk/bmla-approved-courses/
If BMLA approval is important for your employer, insurer or local authority requirements, make sure you check the current BMLA list.
Do you receive a certificate?
You should receive evidence of completion that you can keep with your training records.

https://www.laserprotectionadvisers.co.uk/coreofknowledgecourse
Why is Core of Knowledge training important?
Lasers and IPL systems can be incredibly useful treatment devices, but they can also present serious hazards if they are not used correctly.
Having appropriate training means you understand why certain safety measures are required, rather than simply following a list of rules without understanding the reason behind them.
For example, understanding laser classifications helps you understand why a particular treatment room may need access controls.
Understanding wavelengths and optical density helps you understand why you need specific protective eyewear.
Understanding laser tissue interaction helps you understand how different wavelengths and treatment parameters can affect tissue.
And understanding risk assessment and Local Rules helps you understand how all of these things fit together within your clinic.
That is really what Core of Knowledge is about.
It gives you the knowledge behind the safety procedures.
What else does a new laser clinic need?
Completing your Core of Knowledge course is an important part of getting started, but it is not the only thing you need to consider.
If you are opening a new laser clinic, you should also look at:
Laser Protection Adviser
You may need an LPA to assess your equipment and premises and provide the relevant safety documentation.
Risk Assessment
You should have an appropriate risk assessment covering the equipment and environment in which it is being used.
Local Rules
Your Local Rules should be specific to your clinic and equipment.
Protective Eyewear
You need suitable eyewear for the actual wavelengths and risks associated with your equipment.
Warning Signs
Appropriate laser warning signage should be in place where required.
Equipment Documentation
Make sure you have the correct documentation for the exact device you are purchasing or using.
This is particularly important when purchasing machines from overseas suppliers or buying second-hand equipment.
Treatment Training
Staff need appropriate treatment-specific training for the procedures they are carrying out.
Manufacturer Training
You should also make sure the relevant staff receive appropriate training on the actual machine they will be operating.
Local Authority Licensing
Depending on where you are based, you may need a Special Treatment Licence or other local authority approval.
Ongoing Safety
Laser safety is not something you should only think about when opening your clinic.
Your safety documentation and procedures should be reviewed when you introduce new equipment, change treatment rooms, add new treatments or make other significant changes to the way your clinic operates.
Do I need an LPA when I buy a new laser?
I would always recommend speaking to your LPA before purchasing or installing a new laser where possible.
It is much easier to identify potential issues before you have spent thousands of pounds on a machine and installed it in a treatment room.
Things that may need to be considered include:
The laser classification
Wavelength
Treatment room
Controlled area
Protective eyewear
Warning signage
Local Rules
Risk assessment
Equipment documentation
Staff training
Servicing and maintenance
This is particularly important if you are purchasing an unbranded or overseas device.
Before buying a laser, make sure you have the correct documentation for the exact model you are purchasing.
Do not assume that a CE mark on its own means that everything is compliant.

Frequently Asked Questions
What is a Core of Knowledge course?
A Core of Knowledge course provides the fundamental safety knowledge required when working with lasers, IPL and other relevant optical radiation sources.
Who needs Core of Knowledge training?
It can be relevant to practitioners and staff working with Class 3B and Class 4 lasers and IPL systems in aesthetic, medical, dental and other clinical environments. The exact requirements depend on the equipment, role and local requirements.
Is Core of Knowledge the same as Level 4 laser training?
No. Core of Knowledge focuses on laser and IPL safety. Level 4 training may include treatment-specific and clinical content. They should not automatically be considered interchangeable.
Does IPL require Core of Knowledge training?
Core of Knowledge covers relevant laser and non-laser light sources, including IPL. Whether you specifically need the training will depend on your role, equipment and any requirements imposed by your local authority, employer or insurer.
Can Core of Knowledge training be completed online?
Yes. There are online Core of Knowledge courses available, including BMLA-approved courses.
Does Core of Knowledge training make me an LPA?
No. Completing Core of Knowledge training does not qualify you to act as a Laser Protection Adviser.
Do I still need an LPA if my staff have completed Core of Knowledge?
Potentially, yes. Staff training and professional laser safety advice are two different things. Your clinic may still require an LPA to assess your equipment and premises and provide specialist laser safety documentation.
Does my London clinic need an LPA?
Requirements vary between councils and depending on the equipment and treatments being provided. Your local authority may require LPA involvement or specific laser safety documentation as part of its licensing requirements.
Do I need Core of Knowledge for a laser licence?
This depends on your local authority and the requirements attached to your licence. Some councils request evidence of laser safety or Core of Knowledge training.
Does Core of Knowledge replace manufacturer training?
No. Core of Knowledge covers safety knowledge. Manufacturer training is generally focused on the operation of a particular device and its treatment protocols.
How long does a Core of Knowledge certificate last?
There is not one universal expiry period that applies to every course or every organisation. Employers, insurers and local authorities may have their own requirements regarding refresher training.
Final Thoughts
If you are working with laser or IPL equipment, Core of Knowledge training is an important part of understanding the safety principles behind the equipment you are using.
However, it is important to remember that a certificate on its own does not make a clinic compliant.
You need the right training, the right equipment, suitable protective eyewear, appropriate risk assessments, Local Rules and effective safety procedures.
And where required, you should have access to a suitably qualified Laser Protection Adviser who can assess your actual equipment and premises.
If you are opening a new laser clinic, applying for a Special Treatment Licence, preparing for a council inspection or purchasing a new laser or IPL machine, I would always recommend getting your laser safety requirements sorted as early as possible.
It can save a lot of time and avoid problems further down the line.
