Socialising with friends has always been important to my son too. Luckily we relocated to an area where the homeschool social scene is a pretty vibrant one, with something within a 15 min drive happening most days of the week. The awfulness of the local groups I investigated back in my old locale was a key reason why I never homeschooled while living there.
Before making your mind up about homeschool - do take a look at what exactly your local groups offer. Sadly some are just an extension of mother and baby groups for KS1 kids, but others hire tutors, act as exam centres and run really cool stuff for teens. It's such a massive variation and yet so, so important I think for a child who needs regular contact with peers in order to feel happy.
Look too at the variations of live online schools, correspondence courses, local tutors and colleges too. 14-16 year olds can do their core GCSE's of maths, & english at further education colleges now for free as the gubbermint wants everyone to have these under their belt - this could be a nice stepping stone to sixth form studies at the same institution if you are canny about it. (I don't know WHY further and higher education seem to have a better culture of individuality and SN's than schools do, but it's a phenomenon I've heard spoken about by friends so many times that I think there must be some truth in it. It was certainly my sibling's experience).
Education at home takes many, many forms - there's no way I could help my DS with his science the way his online school teacher is doing and he's only 9!
Knowing there's a group that run GCSE courses and act as an exam centre just a short drive from my new home was a factor in deciding to stick with home ed for DS instead of going to comp. In our case online school will stagger his GCSE courses over 2-3 years avoiding the big pile up at the end of year 11 that I think could trigger his anxieties and make him underperform. If he can do them 1, 2 or 3 at a time using winter and summer sittings at a friendly centre with invigilators he knows, hes far more likely to get that all important maths and english because he won't feel too overloaded iyswim.
Sorry if I've given you more questions to research than answer.
