Our training. Your future. AD24 training academy.

Upskill your technicians with IMI approved courses run by AD24 experts online, in your own facilities or at our dedicated Alexander Dennis training academy in Farnborough.

We can also provide training outside the UK wherever appropriate training facilities are available. Training covers systems used on Alexander Dennis buses and Plaxton coaches, Once trained, your technicians receive an IMI Certificate as part of their personal CPD, enabling you to be confident that you’re maintaining and repairing your own Alexander Dennis vehicles to the highest standards.

Technician training

Equip your technicians with the skills they need to service Alexander Dennis buses and Plaxton coaches to the highest standards. Courses available include ABS, brakes and pneumatics, basic electrical theory, doors, EBS, ELC, Euro 4/5/6 engines and aftertreatment, hybrid technology and zero-emission drive trains.

Apprenticeship training

Develop the skills of your apprentices and get them ready for work with the latest technologies, including hybrid, battery-electric and fuel-cell drive trains. Our apprentice training programmes, built on years of experience, are designed to be hands-on and include using digital multimeter to troubleshoot electrical systems. The duration and content of our programmes are flexible and can be tailored to your needs.

Flexible training solutions

At AD24, we know it can sometimes be challenging to release technicians for training. So our training programme is flexible and designed to fit in around your needs. We have a vast range of courses available that can be delivered either at our Farnborough training centre or on your own premises. If you have a training need that’s not covered by our courses, get in touch to see if we can create a bespoke course just for you.

Enviro Introduction - New Enviro Buses Euro 6

The Enviro Introduction course is ideal for technicians wishing to brush-up their skills on the latest technology and offers great value for money.

Technology in the industry is moving quickly and Technicians must adapt and be prepared to learn. The introduction courses are an excellent starting point.


ABS is an integral part of the braking system on your bus, improving safety, passenger comfort and allowing the driver more control in all conditions.

As a major safety feature, it is important to ensure the ABS system functions properly. Understanding the system and its components will allow your technicians to benefit from good maintenance procedures and help them to identify and rectify faults quickly and effectively.

Air Brake System and Foundation Brakes

With ever increasing capacities on our buses, an Enviro 400 double deck bus can carry over 100 people; it is not surprising we must take Brakes seriously.

We aim to highlight the need for good maintenance procedures on the braking system along with well trained and vigilant Technicians who can spot the early signs of trouble.

Apprentice Training

Over the last few years we have seen many students come through our training centre in Guildford, but one common theme seems to be their apprehension at using a multimeter or to get involved with even the simplest of electrical faults.

With this in mind, the Apprentice Course is designed to cover these aspects in detail and de-mystify the often alien world of electrical systems.

Basic Electrical Theory & Fault Finding Techniques

The Basic Electrical Theory course is not designed to replace specialist Electrical Engineers, but will allow good Technicians to develop their skills and allow them to undertake some basic fault finding steps, before calling for specialist help if required.

Doors: Ventura and Deans

Doors are one of the most heavily used components on a bus, but can easily be overlooked when undertaking routine or preventative maintenance. Properly adjusted doors will ensure trouble free and safe operation for many years.

Electronic Braking System and Electronic Leveling Control

EBS is an integral part of the braking system and works faster than conventional ABS systems, improving stopping distance and greater control in all conditions.

ELC allows finer control of the air suspension; load on the bus is monitored using pressure sensors. The information is relayed to the braking system to ensure maximum braking and stability is always maintained.

Enviro Introduction - Euro 4 & 5 Models

For those operators new to the Enviro range of buses, or for competent Technicians wishing to brush-up their skills on the Enviro introduction course offers great value for money.

Competent Technicians will find the information and hands on experience invaluable in helping to understand the systems involved. With the right Service Manuals, they should be able to resolve the majority of problems encountered.

Euro 4 and 5 - Engine and Aftertreatment

Modern engines use an array of electronic control systems to give outstanding power, improved fuel economy and reduced emissions.

Ensuring your buses continue to maintain their low emission standard is important to the environment, but equally important to the operator. Fines may be given for buses operating outside the legal emissions standards.

Euro 6 Engine and Aftertreatment

Euro 6 engines incorporate EGR and SCR technology and when combined with the exhaust aftertreatment system, ensures the engines meet the latest and most stringent emission levels yet.

Low emissions are important for the environment, but equally as important to the operator to make ensure the buses remain legal.

Hybrid – Level One Technician Course

Starting-up buses used to be accompanied by clouds of smoke, creating an unpleasant work environment and pollution in towns and cities. The latest emission standards have put a stop to this.

Hybrid buses use highly efficient Euro 5 & 6 engines, but the addition of the hybrid system reduces fuel consumption and emissions by more than thirty percent over a standard bus, making Hybrid buses a fantastic solution for towns & cities.

Hybrid Overview and High Voltage Awareness

It is important for all those who work on hybrid buses to know about the high voltage systems on board the bus.

The BAE HybriDrive system chosen by ADL is renowned for its safety, but everyone must know how to work safely on and around the bus. This course will do just that in an interesting and informative way.

Multiplex: Actia System

Multiplex Systems are widely used in the motor industry.

The Multiplex system is used to control a wide variety of chassis and body equipment and provides many safety features such as interlocks. Multiplex systems may at first seem quite complicated, but are much simpler than standard electrical systems and use less relays, fuses and other components making for a simpler system.

Multiplex & CAN - Continental System

Multiplex Systems are widely used in the motor industry. The technology allows us to program many functions and interlocks for safe and reliable operation of your buses.

Multiplex systems can seem quite complicated, but in fact they use less relays and fuses making for a simpler system.

Overseas Training

Overseas Training can be provided in most countries, subject to availability of suitable training facilities, including fully equipped classroom, workshop facilities and a bus available for training purposes. Alexander Dennis has a history of providing highly successful training for overseas operators including Hong Kong, Australia, New Zealand, Singapore, Germany, Canada, USA and Barcelona. Feedback from these customers rates our training as amongst the best they have received.
