Contact Us

We have received a number of calls from people about nuisance calls related to the Green Deal. We are unaware who is making these calls, but don’t believe it is one of our authorised GD Participants. Please contact the Information Commissioners Office to report your concerns. Please also let us know details by emailing our helpdesk so we can keep a track of complaints.

We also recommend that you register with the Telephone Preference Service if you have not already done so. Although registering will not physically block marketing calls, it should reduce the overall number of these calls that you receive.
