You can now order your PAT Tester Calibration online. Please complete the fields below. We will email you with an invoice as soon as the machine has been calibrated and you can pay by credit card or BACS.

Please note that if you live in the Islands or Highlands of the UK, you will need to send us the PAT Tester as it is not cost effective to use the Courier. The Royal Mail provide the best service unless you already have a courier that you use. You do not need to complete the form below if you are sending the machine to us.
