Our inspection service was established in December 1965. Since then we have successfully completed thousands of inspection and debris-retrieval assignments. All work of this type is carried out by fully-experienced operators using a wide range of specialist equipment. Witnessing of inspections by a responsible representative of the client is encouraged. Wherever possible we insist that covers are fitted, in our presence, immediately following inspection. Details of any factors which may influence the security of the plant are recorded. An inspection report is submitted to the customer and two further copies are held by Jackson Electronics. These are stored in separate locations to protect against loss of information by fire. All records are retained for a period of ten years.

Video recordings can be provided on DVD/USB Flash drive plus a range of legacy media
