The annual Club Hub Top 100 Awards recognise children's activity providers from across the UK. Entries are independently assessed against five key areas: the benefits of the activities offered, safeguarding, inclusivity, community impact and business achievements. The awards aim to help parents identify providers that demonstrate high standards and make a positive difference to children and their communities.

Charlie Tarrant, Owner & Director of CSS Activities said: "To be recognised as the UK's number one children's activity provider is an incredible honour.

"This award belongs to our whole team. Every instructor and leader brings energy, care and enthusiasm to camp each day and we're incredibly grateful to the families who trust us with their children during the school holidays.

"When we launched CSS Activities in 2021, our aim was simple: to create a safe and fun environment for children in the holidays, support working families and offer a high quality activity programme. To receive this recognition just a few years later means the world to us."

CSS Activities was established in 2021 following the Covid-19 lockdowns, with the aim of giving children opportunities to be active, learn new skills and reconnect with others. The business has since expanded from one site to holiday camps at Portsmouth High Prep & Pre-School GDST, Oakwood School in Chichester and Ardingly College near Haywards Heath, supporting thousands of local families with flexible childcare throughout the school holidays.

Beyond its holiday camps, CSS Activities works closely with its partner schools throughout the year by supporting school events, delivering assemblies and becoming part of each school community. The business also supports wider community initiatives, including Stonepillow's Big Sleep Out and its annual Community Christmas project, while recently helping deliver swimming and water safety education in Uganda.

CSS Activities Portsmouth summer holiday camps begin next week on Monday 13th July at Portsmouth High Prep & Pre-School GDST, welcoming children throughout the school holidays alongside camps in Chichester and Ardingly.
