Option Skills - BirminghamI’m not usually a person who will write feedback on Google, but I am someone who will give credit where credit is due.I found myself in a position where I had been made redundant, and id had a conversation with someone who’d decided to go on a gas course and do this through Option Skills. After speaking with the individual, I decided that id give this a go myself to give myself a trade.I can honestly say that it is better than anything that id ever expected. Iv always been someone who had worked in finance, so doing this was new to me and I was a bit apprehensive with how it would go.I have nothing but praise to the employees at Option Skills, and I feel that they are a credit to the company.Andrew, Leanne and Shaun have been the people taking the training sessions, and what incredible people they are.They are extremely knowledgeable and helpful in every way possible with an extra desire to wanting to see you achieve.I have done the course for 8 weeks, and the knowledge I have picked up already is immense.If you are someone looking to get into the gas trade, I would highly recommend Option Skills as you will not be disappointed.Carl Evans

Although this course is intense and you will find yourself picking up a lot of information in a short space of time, Options Skills are the best way to get into the trades if you are a fast learner and are willing to work hard. The trainers are excellent (John, Steve, Thomas) and they will help you wherever they can, however be prepared to put in the work yourself in the evenings and weekends to revise and pass exams. Josh and James from the recruitment team were a joy to work with, they work tirelessly to find us all placements to start working in the industry while you complete the portfolio part of the course. I just finished the Electrical 6 week course and the lads found me a job in Birmingham city centre. With a number of exams left to do and portfolio to complete after you finish the 6 weeks in-centre, you can expect the total time to reach being qualified to be around 1-2 years.

Great service from start to finish. Course is very well run & enjoyable. Prepares you for the world of electrics, with constant support from trainers Colin or John when needed. After the course is finished Josh and his team work around the clock to help you get a foot in the door at an electrical company. Constant support & updates, giving you confidence in what can be a hard process. Making it very smooth and simple
