Celebrities across Britain are volunteering to help raise money for good causes by getting involved with The Great British Win challenge.

They are offering the chance to win once-in-a-lifetime experiences, with money going to Refuge, Meals for the NHS, Age UK and NHS Charities Together.

Some of the unique experiences on offer are: a five-star banquet dinner and night out with Made in Chelsea's Alex Mytton and his Chelsea friends; an A-list day out with fashion guru Susannah Constantine including lunch and a fashion makeover; VIP sporting experience with Love Island's Charlie Brake and afternoon tea at The Ivy with Arlene Phillips. Donations to enter start at £5. For all information, experiences available and to donate, go to www.greatbritishwin.co.uk.
