BEWARE ROGUE TRADERS
We have been made aware that people are trading with the Klober name
saying that they are Klober factory approved installers, this is incorrect
as we do not endorse any fitters. Should you come across one of these
rogue traders please obtain company name, vehicle registration number and
contact details. We will investigate all complaints.
When using traders within your home ensure that the contractors that you
use have a trading address and VAT number, if you have any concerns about
any traders contact your local Citizens Advice Bureau.
