Stephen lost his battle with bowel cancer, in May, aged just 19.
His story inspired thousands – using his trademark thumbs-up – and raised an enormous £3.4 million for the Teenage Cancer Trust.
Stephen, from Burntwood, Staffordshire, accepted the honour before his death, after the Cabinet Office wrote to the teenager, asking if he would accept the honour.
His mum, Jane, has said she is “truly delighted and immensely proud” that Stephen’s efforts had been recognised, adding:
“Although Stephen continually told all of us that he didn't do his charity work for recognition, even he acknowledged that to be appointed an MBE was 'awesome’.”
Also recognised in today’s list are Martin Lewis – the money saving expert – and fashion designer, Zandra Rhodes. Both will be awarded OBE’s.
