but ideally he would like a technical based job in computing but he doesn't have the experience.
Then he needs to get it.
I work in tech and occasionally hire entry-level positions (so normally 22/23, most of whom will also have an MSc on top of their 2:1s/1:1s).
There are SWATHES of highly-motivated, well-qualified youngsters coming through, so the competition is fierce.
There are plenty of free online courses and MOOCs in coding/development/IS/digital solutions/data science that he can be doing while he's not working (look at LinkedIn Learning, although you need to be a premium member to access some content), and a lot of charities are looking for people to help out with digital content management/social media/front-end development.
Can he build apps or dev sites which will help him to put together a portfolio of what he's capable of? Basically, given the amount of time lapsed between his degree and now, he's not going to walk into a tech role, mostly because of the speed at which the industry moves, so he will be expected to show how he has maintained and developed skills.
If he has a degree in a computing-type field, he's obviously not stupid, but to get to 26 and not even have found a first entry-level role is pretty bad, to be honest, and won't look great on a CV.
He's going to have to buck his ideas up pretty quickly (and I would respectfully suggest you might want to have a look at how you might be enabling him).
