I know a college that combines the C&G 2661 and EASA Licence into one course; therefore at completion of the course you will be getting both qualifications. The only reason for this, is that with the C&G 2661 the college with received government funding, because the government doesn't issue funding for the EASA licence course.
A C&G 2661 will teach you the basic knowledge that you required for an A Licence, but in no way constitutes to an A Licence. A C&G 2661 by itself (without experience) may help you get a job in a smaller organisation, but will struggle with a bigger organisation. My opinion is that (according to you location) apply for the EASA A Licence + C&G 2661 course at Northbrook College at Shoreham Airport, you will be much better off.
