Survey finding
Full electrical rewire flagged in your survey
A rewire recommendation is a more specific and significant finding than a general electrical flag. This page explains what typically sits behind the recommendation, how to scope the work, and what to ask before exchange.

Finding
Full electrical rewire needed
What this usually means
A full rewire recommendation is a more specific finding than a general electrical concern. It typically means a surveyor or EICR has concluded that the wiring installation is near or beyond the end of its safe service life, for example rubber-insulated or lead-sheathed cables, aluminium wiring from the 1960s/70s, or an installation that would require so many C2 remedials that replacement is more practical than piecemeal repair.
Why it matters
A full rewire is one of the larger single items of work in a domestic property. It is disruptive (requiring access to walls and ceilings), carries safety implications, and is increasingly asked for by insurers on older properties. The cost scope is distinct from a consumer unit upgrade or partial remedial.
Ask your surveyor
- Check:What is the specific reason for recommending a full rewire rather than targeted remedials, and what type of wiring is present?
- Check:Is there a recent EICR, and if so what classification codes were issued?
Ask the seller
- Check:When was the property last rewired, and do you have any EICR certificates?
- Check:Has any electrical work (partial rewire, consumer unit replacement) been done by a registered electrician with a Part P certificate?
Next steps
- •Commission an EICR from an NICEIC or NAPIT registered electrician if one is not already available, so the scope and classification are clear.
- •Get at least two written quotes for a full rewire before factoring the cost into your offer thinking.
