4-day Electrical Foundation Course




4 days




The Builder Training Centre (The BTC) offers high quality structured Foundation Electrical Courses, which can be attended as a weekday course (usually Monday to Thursday) or, for those that have commitments during the week, a weekend course (2 consecutive weekends).

Our instructors are qualified, highly experienced, knowledgeable and enthusiastic Tradespersons, so students can take advantage of all the tips of the trade, personal experiences and advice they offer. Our short courses are intensive, but the atmosphere is relaxed and enjoyable which creates a good learning environment. If you have a particular project in mind, or some building plans you wish to gain advice on, our instructors will be more than happy to discuss these with you.

The 4 day Foundation Electrical course covers the theory and practical skills required to undertake most electrical installations within the domestic environment. It covers all the elements of the 2 day Foundation Electrical course and takes you to the next level with additional circuit installation and testing practice, including live testing and fault finding.

The Course covers practical skills from applying Ohms Law and calculating correct fuse ratings to installing and testing circuits.

This course combines the 2 day Introductory Electrical Course and 2 day Inspection and Testing Course, and can be booked as two separate courses, or combined as one. This course is an obvious choice for those wishing to progress onto our electrical qualification courses.

This course combines the 2-day Electrical Foundation Course and 2-day Inspection and Testing Foundation Course, and can be booked as two separate courses, or combined as one.

For people looking to gain a complete understanding of electrical principles or to progress onto the qualification courses, this is the obvious choice.

Steel toe-capped safety footwear is a health and safety requirement for all our courses. We stock steel-toe capped boots from size 3 to 13 (with some half sizes), which can be purchased on the first morning of your course for just £20.00. You should wear suitable comfortable clothing that you do not mind getting dirty.

We provide all relevant tools and materials that are required for the duration of your course.

Changing facilities for men and women are available on-site. For a £5.00 deposit you can get a padlock to a locker for any small valuables you may wish to bring along.

You are welcome to bring your own food to eat in our canteen. Alternatively, we sell a small selection of hot and cold drinks and snacks, or you could purchase food from one of the local supermarkets/shops/cafes/restaurants within just a few minutes’ walk.

Provided you are aged at least 18 years and deemed fit and healthy to complete physical work, this course is suitable for you. Whether your background is already in a trade or something completely different, these skills can be learnt and applied directly after the course.

Over the years, we have had students attend the course for many reasons, the most popular of which would be to expand their current professional services, start a whole new career or to just pick up a new skill for DIY. These are not just skills for one project, these are skills for life!

The 4-day Electrical Foundation course can be attended either over 4 consecutive weekdays (Monday-Thursday or Tuesday-Friday), or over two consecutive weekends (Saturday & Sunday).

The content of the course is the same and it will follow the same structure. However, please note that the weekend courses start at 8.30 am instead of 9 am to maintain consistency with our other weekend courses.

You will be awarded a Builder Training Centres Limited Certificate of Continuous Professional Development after full completion of the course. The Certificate will include your name, the dates you attended, and on the reverse we list all the areas you have covered throughout your course.

Course notes will be provided during your course. These will summarise most of the topics covered with some diagrams and pictures also included, however, you may choose to bring along a notepad and pen to take additional notes.

As we are located within Waddon Train Station Buildings, we do not have any parking on-site. That said, there are plenty of residential roads in the surrounding area that have free unrestricted parking, within just a few minutes’ walk. If attending on Sunday, you can park in the marked red boxes in Epsom Road where our Centre at Waddon Station is situated and in Stafford Road where our Electrical Centre is situated (a minute’s walk away) all day free of charge.

"Very insightful. I will come away with a much greater understanding of electrics. It will give me confidence to a) question tradesmen with future problems and b) allow me to think about retraining as an electrician. Speed of delivery and way it was taught was spot on."

"Excellent – I’ve been on other courses so you already know that I like the place! Richard was really patient and explained everthing very clearly. Initially it was location but now that I’ve done courses here I wouldn’t go anywhere else even if it was half the price. Can’t wait to do the Part P and 17th Edition."
