Works on the River Cam


All works in, on or near to the River are likely to need a consent from us.   


Please complete our online application form.  An initial non-refundable consideration fee of £300 is required (should we consent to the works the final consent fee will be reduced by this amount).

You may also need to obtain a permit from the Environment Agency - you can check this on their website.

As a guide here are key considerations:

  • What are the reasons for the works to be undertaken?

  • What form will the completed works take in satisfying these reasons?

  • What impact will the works have on other river users, both (a) during the works themselves, and (b) once the works are complete?

  • Will a navigation restriction be required during the works (this could include restriction of the navigation width, management of river traffic, communication to river users and consultation with those affected)?

  • Will the works present any safety risks to river users? (Safe ways of working should be in place, and can be demonstrated by the provision of method statements/risk assessments).

  • Are diving operations required as part of the works? (If so, have safety boats been considered? Does the towpath need closing? Will additional navigation restrictions be necessary?)


Our 2020/21 fees are:

  • Navigation obstruction ( e.g anything entering the River)- up to 14 days - £1500

    • Per additional week - £750

Complete our online application form.

If your works are likely to require the Middle River (the Backs) to be lowered / drained - here is our guidelines for this.
