In most cases you’ll only need a standard install meaning there’s no additional cost. In some cases you’ll require what we call a non-standard install (wild name we know). This could be for a few reasons, like your property is surrounded by trees or higher buildings (or you live in a burrow) meaning the aerial will need to be higher to get the best signal. We’ll only be able to identify if you need a non-standard during the installation process when our engineers are at the property. We try our best not to have to charge more, but in some cases this is out of our hands and an additional installation fee may be charged. Hope you understand.
