The Henry Allen Trust

Supporting children, teens, young adults and their families battling childhood cancer.


The Henry Allen Trust is a registered charity based in Milton Keynes that supports children, teens, young adults and their families battling childhood cancer throughout the UK and has been operating since 2014.

The Henry Allen Trust was started in memory of Henry Allen who was two years old when he was diagnosed with Stage 4, MYCN Amplified High Risk, Neuroblastoma. Two years of painful treatments and surgeries couldn’t knock Henry down, his happiness and bravery throughout his journey inspired everyone around him.

Henry changed the lives of so many and, before he gained his wings so sadly in October 2013, he insisted his parents continue his wish helping other children.

This is how The Henry Allen Trust began, and this is why supporters of the trust are so dedicated today. Everyone involved within the Trust is still working to fulfil Henry’s wish - helping families who need to find smiles when they’re in pain. The Trust works tirelessly to ensure no family feels alone during their cancer journey.
