Please note GDHV Contact Centre is now closed for the festive season. Normal opening hours will resume on Monday January 4th but for any urgent assistance on December 29th, 30th and 31st, lines will be open from 9am to 4pm.
Please listen carefully to the menu options to ensure your call is routed to the correct team and to avoid unnecessary hold times. During sudden changes in temperature, our phone lines become extremely busy and hold times may be longer. We encourage you to use our Online Form for less urgent queries.
In order to provide you with the best possible service, we ask that for all fault/product issues that you have the details of the product including model and serial number, date of purchase or installation and if required the proof of purchase. This ensures we can assist the first time you contact us.
