Our objectives are -

•  To provide information

We will endeavour to provide the latest information from all sources, regarding the progress of the construction work, and the timetable envisaged for future works. Following Royal Assent, HS2 agents may now enter private propety; this page outlines the position (as seen by HS2 Ltd) (More...)

•  To monitor the construction process

We will maintain a record of work currently in progress, and check that the works are carried out in accordance with the Code of Construction Practice, the Community Engagement Strategy, and with the Assurances given during the passage of the HS2 bill. (More...)

•  To monitor and assist with complaints.

We will maintain a list of contacts for HS2 Ltd and their contractors, so that complaints can be directed to the appropriate bodies. We will maintain a log of complaints made, and the outcomes. If the outcomes are unsatisfactory, or the nuisance is not abated, we will take up the case with higher levels of management.
Clearly HS2 Watch cannot monitor the entire HS2 project on their own. We ask anyone with information which may be of use to share it with us, via
