## What it means in practice

Read this alongside [NEC guidance on defining and managing defects](<https://www.neccontract.com/news/defining-and-managing-defects-in-ecc-and-liability-for-not-correcting-them>).

The defects or rectification period provides a contractual route for dealing with defects after completion. Its expiry does not necessarily end liability for defective work. Retention release may also depend on making good, certification and payment provisions rather than the passage of time alone.

Record the end date, reported defects and completion evidence. [Retention recovery](<https://www.quantsurv.com/retention/services/retention-recovery>) starts with the release conditions applicable to your subcontract.

## Worked example

### The facts

A joinery package has reached the end of an agreed rectification period, but a reported door defect remains open.

### What happens

1.  The subcontractor checks responsibility and records any agreed remedial work.
    
2.  It identifies the certificate or other event required for the remaining retention.
    

### What this shows

The date is one part of the release assessment; the contractual conditions and evidence still matter.
