Understanding Your Property Passport Completion Score — What It Measures and Why It Matters

What is the Completion Score?

The Completion Score is a percentage that indicates how complete and verified your property’s digital record is on Property Passport UK. It is calculated from two components:

1. **Automatically verified data** — information drawn directly from official sources (HM Land Registry, EPC Register, Ordnance Survey, Environment Agency). This data is verified by source, not by the owner.

2. **Owner-uploaded documents** — documents, certificates, and records uploaded by the property owner to the document vault. These add to the Completion Score when they cover categories that are currently missing.

What Contributes to the Score?

**Official data (auto-populated):**

• Land Registry title registered: confirms ownership
• EPC certificate present: energy efficiency rating verified
• UPRN confirmed: property is uniquely identified in official records
• Sold price history: transaction history from HMLR
• Flood risk assessment: Environment Agency classification

**Owner-uploaded documents:**

• Planning permissions for extensions or alterations
• Building regulations completion certificates
• FENSA/CERTASS glazing certificates
• Gas safety certificates and service history
• EICR (electrical installation condition report)
• Structural engineer’s reports or surveys
• Damp-proofing and timber treatment guarantees
• Leasehold documents (for flats and leasehold houses)

Each document category has a weight in the overall score. Categories that represent higher-risk or higher-value information carry more weight than minor items.

Why a Higher Score Matters

**For sellers:** A high Completion Score demonstrates that the property has been well-maintained and properly documented. Buyers and their solicitors can see at a glance that the key documents are in order, which reduces enquiries and speeds up conveyancing.

**For landlords:** Tenants are increasingly interested in the documented history of a property — particularly energy efficiency, boiler history, and electrical condition. A high Completion Score builds confidence.

**For buyers:** The Completion Score gives a quick indication of how much documentary evidence the seller has available. A low score does not mean the property has problems — it may simply mean the owner has not yet digitised their records.

**For conveyancers and agents:** Professionals can request secure access to the document vault, allowing them to review documents before instructing searches or drafting contracts.

Improving Your Score

1. **Check what is missing** — the Completion Score dashboard shows which categories are empty

2. **Locate existing documents** — many are in a paper file from when you bought or from works contractors

3. **Upload to the vault** — PDF scans or photographs are accepted for most document types

4. **Request official documents** — HM Land Registry official copies, EPC certificates, and UPRN lookups are all available online

Most properties can reach 70–80% completion within a few hours of document gathering.
