Flexible Payment Options

Secure your place today by paying in full or spreading the cost with our simple interest-free monthly instalment plan.

If you choose the instalment plan, your monthly payments are automatically calculated based on how many months are left until the event — so the earlier you sign up, the lower your monthly payments will be. As time goes by and fewer months remain, the monthly amount increases to cover the full ticket cost over the remaining time.

For example, if you sign up with 5 months remaining, the Adult Entry Price of £75 would be split into 5 monthly payments of £15.

If you wait and there are only 2 months left, the same entry fee would be split into 2 monthly payments of £37.50

Simply complete the entry form and select the instalment plan at checkout — your personalised payment schedule will be created instantly.
