Fixed Wire Testing

Fixed Wire Testing

Mandatory requirement for all commercial premises


Fixed Wire Testing is a mandatory requirement for all commercial and industrial premises. All electrical installations suffer damage and deterioration throughout their operational life, which makes these tests essential in confirming the safe operation of the installation.

Often seen as a complex and expensive problem or “dark art” by managers and business owners, CES works to make this essential process straightforward and transparent for its customers and partners.

CES has a structured and unique approach to managing Fixed Wire Testing. Our aim is to proactively give the customer sufficient information to enable them to minimise disruption during testing and remedial maintenance.

Communication is the key to our success

Fixed Wire Testing

Our fully trained engineers carry out an inspection prior to commencing work, to ensure any critical operations are not unduly affected by the testing (comms rooms, etc.). Any critical issues are brought to our client’s attention immediately and a plan of remedial action is agreed.

Quality and accuracy of reports are critical to the electrical safety process. Our reports are thoroughly checked by a Qualifying Manager before being made available on-line.

Customers and partners have easy access to all certificate and documents online so they can be presented to an insurer or inspector on demand.

Ultimately it is the people that make the process work. All our engineers have City & Guilds 2360/2391 and IEE Wiring Regulations (18th Edition) qualifications and we undergo an NICEIC audit every year in order to validate that we have the skills, know-how and procedures to help keep your business safe and compliant.

CES are recognised experts in this type of Electrical Testing and can help you ensure that your organisation complies with all the relevant electrical regulations. To discover more about CES and our unique approach to Electrical Testing Services, please get in touch.
