As has been said your easement will probably be a right of way only over land owned by others. Under section 62 of the law of property act 1925 when the land is conveyed all easements appertaining to it pass automatically. There is also an easement of necessity, which is usually where land would be useless without the easement for access, an easement can be for uses other than as a right of way such as use of a toilet or parking, you may be interested in Copeland v Greenhalf 1952, you may also wish to check if the easement is registered with the land registry.
