Installation, cabling and lead times
- The installation fee includes cabling up to 30 metres. If your installation requires additional cabling, a site survey will be done, after which you will receive a quote from the applicable last-mile provider. Should you choose to proceed, you will be liable for any additional costs incurred. The additional cabling is directly payable to the applicable last-mile provider.
I can advise you to check coverage in your area and then contact applicable last mile provider (fibre provider) to find out how much they going to bill you for 1 metre there after you will be able to work out your calculations for additional cabling.
