It is wonderful news that your son has found a job.
I have just checked with Dee, who works in our Lifestyles and Work team, and she said:
‘’Your son would be eligible to get funding to employ a Job coach to help him learn the tasks and to settle into his job This is called Access to work and is government funding .You can contact them on 0800 121 7479 .Most employers will welcome this additional help
Access to work can also fund transport if he needs that help ‘’
I really hope this helps.
