Why we chose Remit? Automotive is the core for Remit..it’s also their ability to change. The automotive industry is changing massively and it’s changing quicker and quicker and Remit have that ability to change and it’s driven all the way through. We’ve worked with the Scottish arm of the business for some years now and we’ve found that relationship to be really productive so my thoughts would be that would spread across the business, and my thoughts would be correct.

Turning Point

“

We have had a steady stream of successful learners through a range of programmes at Level 2 to Level 5 with Remit. Some learners have required additional support, which Remit have gone above and beyond in supporting.  There are regular review meetings where we discuss how we work together to find the best route to success for our learners as we genuinely feel that apprenticeships give our staff an opportunity to grow, learn and develop new skills and ways of working that ultimately support the outcomes for people we support.
