An EICR is valid for up to 5 years so it is possible that a valid report will already be in place when the contract-holder moves in and may not expire before the contract-holder leaves.
Mae EICR yn ddilys am hyd at bum mlynedd ac, felly, mae'n bosibl y bydd adroddiad dilys eisoes ar gael pan fydd deiliad y contract yn symud i mewn ac na ddaw i ben cyn i ddeiliad y contract adael.
