Education Booking Terms and Conditions Bookings available for UK and international schools, exclusively Mon-Fri during UK school term time only. If your class is visiting outside of UK term time you may be eligible to book with our groups discount. See our admissions page for more details. Bookings must be made in advance for classes to be eligible for the school rates. 50% payment for an education visit must be made at the point of booking and the remaining balance at least two weeks in advance of the visit and can be made by BACs. As a condition of the entry costs for school visits, Teachers and accompanying adults must supervise their groups at all times during their visit. We offer one free adult per six paying primary school students and one free adult per ten paying secondary students to ensure adequate supervision for school groups. For schools that don't meet the minimum number to qualify for these prices, please book via our groups page, where for groups of more than 12 can benefit from group rates of 10% off general entry. Adults leading school groups are expected to follow the supervision guidelines and behaviour expectations set out by the HCC. These guidelines can be found on our Education page. Any failure to follow these guidelines can result in a group being asked to leave the HCC and school management being contacted. If you amend your booking or cancel within two weeks of the scheduled date or no show on the day of your visit, the HCC reserves the right to charge an administration fee of £50. If payment is not received by the day of your visit, an invoice with a £50 administrative fee will be raised. This must be paid within one week of the invoice being raised, or will incur an extra £50 for each week not paid. A new week begins 7 days from the invoice date. As part of an education booking, you agree to complete our feedback form after your visit which shall be emailed to you. We require this to be completed within two weeks of your visit, or there will be a fee of £25. If for any reason a booked session (i.e home schooling) cannot take place, the HCC will offer a re-schedule date, convenient to all parties. Unfortunately refunds are not available unless the sessions are cancelled in their entirety by us and no alternative can be arranged. Education prices cannot be used in conjunction with any other offer, promotion, discounts or third party payment methods. Membership cards can be used but they will not count towards the free adult ratio for supervision purposes. For every class booked in to visit the Zoo, we allow one free pre-visit for one teacher. If your booking is for multiple classes, we allow up to two complimentary entries for a pre-visit.
