About our services

Annual calibration of your electrical testing equipment is widely regarded as the best method of continuously ensuring that your equipment is providing accurate results in accordance with its specifications. Calibration provides peace of mind for the user and it documents that the user has taken reasonable action to ensure the accuracy of their test equipment. As part of this NAPIT also promotes that its members ensures annual calibration of their test equipment and that equipment is calibrated in a controlled environment. 

We understand that aside from this, calibration is also a matter of solving an often logistical challenge to ensure minimum possible downtime and retaining clear communication throughout the process. Ensuring that the engineers handling your equipment are trained and skilled to do so is of equal importance.

The NAPIT Calibration service is designed to cover all of the above.


NAPIT Calibration endeavors to ensure that your test instruments are calibrated AND returned within 2-4 working days from receipt. This lead time does not include weekends and Bank Holidays. All items are collected and returned using DPD who offer maximum traceability and a 1 hour delivery time window for both the collection and delivery. Amending the delivery date, location or providing other delivery/collection instructions can easily be managed by you, the recipient.

The delivery and collection service is charged at £9.95+VAT on top of the calibration cost itself which you can find in the Price List section.

Please note: All delivery costs are for mainland UK only. For non-UK mainland, please call 0113 248 9966.
