You only need to pay an initial deposit of £35 per adult and £20 per child aged two to 14 unless booking within 70 days of the start, as that’s when you’ll need to pay in full. Butlin’s are happy for you to spread the cost throughout the year. If you booked online log into your Butlin's account to pay in installments or visit www.butlins.com/pay to pay towards your booking any time before final payment is due.
