Many bonds overrun and therefore incur fees. This is for numerous reasons; there can be delays on both the side of the authority, e.g. in getting out to inspect remedial works, and on the side of the house builder, e.g. in returning to a site to complete repairs to enable adoption. Overall, the current system appears to offer poor protection for the consumer, with roads remaining unadopted for years, which can create problems when repairs are needed and it is not obvious who is responsible.
