Periodic Inspection & Testing of your fixed electrical installations
NICEIC-certified fixed wire testing (Periodic Inspection & Testing) for commercial and industrial premises. Electrical Installation Condition Reports (EICR) issued.
About Our Fixed Wire Testing Service
Fixed wire testing — also known as Periodic Inspection & Testing or Electrical Installation Condition Report (EICR) — is the assessment of your building's permanent electrical wiring, consumer units, distribution boards, and fixed electrical systems. Unlike PAT testing which covers portable appliances, fixed wire testing examines the infrastructure that powers your entire premises.
MES PAT Testing Ltd provides NICEIC-certified fixed wire testing across Essex and the South East. Our qualified electricians conduct thorough inspections and testing of your fixed installations, issuing an EICR with a clear condition rating and any remedial recommendations required for compliance.

Frequently Asked Questions
Common questions about fixed wire testing
How often is fixed wire testing required?
Commercial premises typically require an EICR every 5 years. Rental properties require one every 5 years or at change of tenancy. High-risk environments may require more frequent inspections.
What is the difference between PAT testing and fixed wire testing?
PAT testing covers portable electrical appliances you can move and plug in. Fixed wire testing covers your building's permanent electrical installation — wiring, consumer units, sockets, and switches.
What do the EICR codes mean?
C1 (Danger present — immediate action required), C2 (Potentially dangerous — urgent action required), C3 (Improvement recommended), FI (Further investigation required). C1 and C2 results mean the installation is unsatisfactory.
Are you NICEIC approved?
Yes — MES PAT Testing Ltd is NICEIC approved and all fixed wire testing is conducted by qualified electricians. Our EICR certificates are legally recognised and accepted by insurance companies.
Is an EICR required by law?
For rental properties since 2020, yes — landlords must have an EICR every 5 years. For commercial premises, while not always explicitly required, it is best practice and often required by insurers.
