Inspection and Testing

Businesses are becoming more aware of the 'duty of care' they owe to employees and visitors to their sites. The financial implications of not protecting the Health and Safety of personnel cannot be ignored, neither can the possible delay and cost incurred by preventable breakdowns that could have been identified and rectified at an early stage.

Due to the importance of testing Gra-Bern ensure that all electricians are fully qualified and conversant with current BS7671: 2008 wiring regulations. All hold current City & Guilds qualifications, including C&G 2391.

All testing is carried out with fully calibrated and serviced test equipment, which undergoes regular in-house inspection to ensure on going accuracy. All testing is reported on computer generated test certificates and reports.
