To use this site an individual must register on the site. All users will be required to give a unique username & password which will be needed to login to the search facility on this site. All registered users have access to their search history.


Enquirers will be able to enter all enquiries onto the system and an initial search will be made against the information held. This will be in the form of a ‘Zone of Interest’ based on geographic information. Each Member will be able to define their own ‘Zone of Interest’ for the search to be made against, which varies from 25 metres to 250 metres either side of their apparatus.

If the proposed works are outside the  'Zones of Interest' an automatic email response is sent to the enquirer advising them of this fact and there is also a results print screen facility.

If, however, the work is within a ‘Zone of Interest’ then further details of the work will be requested. The enquirer will be advised of the correct contact details and the additional information required. This will be dealt with directly by the Member concerned who will undertake the detailed search and will then be responsible for making the necessary responses to the enquirer.

Responses made to enquiries entered into Linesearch.org are only valid for 28 days from the date they were originally entered. If the works are not completed within that time frame an additional search will have to undertaken to confirm that there have been no changes made to the apparatus designations since the original search was undertaken.
