Are you an electrician, associated trade professional, trainee or newcomer to the industry? Our maths for electricians is part of our bite-sized essentials range and is the perfect tool for the bag.

This bite-sized course is delivered online and can be completed using a PC, MAC, or tablet and is available anytime and anywhere.

Once the enrolment process has been completed, candidates will be emailed access to the online course material within 24 hours. 

Our Maths for Electricians course is designed to provide you with the necessary mathematical skills for practising as an electrician in a domestic, industrial or commercial setting. Whether you are a student interested in entering the trade or an experienced electrician seeking a refresher, this course caters to both groups.

Mathematics often carries a reputation for being difficult and complex. While some aspects of maths can indeed be challenging, the mathematical concepts we utilise as electricians are generally manageable. Moreover, mathematics is a fundamental part of our daily lives. It helps us calculate the value of a two-for-one offer and estimate the time it takes to travel from one place to another. In our Maths for Electricians course, we will employ similar mathematical principles, applying them specifically to our learning and work in the field of electrical work.

This course starts from the basics, making it accessible to everyone, regardless of whether you have a GCSE in maths. If you find the initial topics too easy for your level of understanding, feel free to skip them and proceed to more advanced lessons and topics within the course. Every lesson includes practice questions to reinforce your learning and allow you to apply what you have learned.
