How long is a Part P Domestic Electrical Installation Certificate valid for?

A building regulation Part P certificate lasts for ever, whereas an Electrical Installation Certificate is normally valid for between 5 and 10 years. I think your referring to an EIC document as its dated, so you could assume its valid for up to 10 years from that point.

Hi The certificate you posses is for the works that have been carried out and identified on that certificate. In your case, a new consumer unit with bonding. This certificate is valid until the date shown near the bottom of the first page - Date of next recommended inspection. It does not cover any other part of your electrical distribution system. That being said, the contractor should have tested all of the existing circuits when a new consumer unit was fit and those results can be found on the last page of your certificate. If there were any significant anomalies whilst testing those circuits, he should have at least recorded them in the "comments on existing installation" , and in some cases rectified them. The term"satisfactory" in that section of the report is rather poor and a bit more detail should of been recorded. If you are going to have further work carried out soon, then any further testing at this point is not necessarily needed, as your future contractor can take on a full test if you so wish. If no further work is planned in the near future than the Electrical Safety Council recommends that an owner occupied domestic property is tested every 10 years. Hope this helps
