If we are to carry out your installation, we will ask for a pre-payment before the work starts; once the installation has been completed the balance of the installation invoice must be paid in full before leaving any marina or port. Any installation will be estimated and sent to you in writing, which you will need to approve before we start the work. If additional items are required during the installation, we will advise you in writing and require your agreement.
