We’re on the move so get ready to update your contact details for us.


On 18th June, we will relocate the Validair Diamond Scientific HQ from our current office in Darlington to Chester-le-Street, so get ready to update your contact address for us effective from 21st June.

During the move, we intend to remain fully contactable and maintain our usual high quality of service. Our IT system will be relocating on the 18th but we’re not expecting any significant outages, so we should still receive emails. In addition, we are implementing a new 0330 telephone number for everyone’s convenience, and that will become our preferred contact from 21st June. However, our existing phone number will not change and will still work. Feel free to use either number.

  • Tel. 0330 056 3887
  • Tel. 01325 481048

Here’s our new office address:

Validair Diamond Scientific
(A trading name of Validair (Euro) Limited)
