14 yr old boy looking for Friendships - Surrey or Online

Hi, my son is a very social 14 year old boy who is struggling, yet desperate, to make friends and expand his social circle.   Lately he's been seeing his siblings go out and speak regularly with friends and he's feeling very isolated and is trying to make friends in the Surrey (Guildford) area or online. The closest he's managed is an online friend in Ireland!  He enjoys going out to playgrounds and even takes the occasional football shot!  He loves computers and video animations, especially making his own YouTube videos!
