Section 8 places a requirement on the owners of caravan sites (to whom Part 2 applies) to provide caravan owners with written statements covering the terms and conditions upon which their agreement is based within a specific time limit. Any express term of the agreement not given in writing will be unenforceable by the site owner. The intention is to provide site owners with an incentive to comply with the duty to provide a written statement and protect occupiers from the application of terms that have not been given in writing.
