Hi,
I don't think the time between doing A levels and going to uni is going to be a problem, plenty of mature students get accepted. People go to uni at all different ages and stages of their life. They take into account grades, experience, interests, career goals etc. I would recommend contacting the admissions team for the unis you are interested in and even seeing if you reach out the course leader and seeing what the recommend.
