What is a PDI Digital Property Pack?

A PDI Digital Property Pack is a single, reconciled JSON (and optional PDF) bundle for any UK address — identified by UPRN. It pulls together listings, ownership and tenure data, AVM valuation, EPC, council tax, flood risk, planning history, comparables and material information into one governed payload.

Packs are built on the same schema and lifecycle the UK conveyancing market is converging on: BASPI v5 for material information and PDTF v3.5.0 for the property data trust framework. As an OPDA member, PDI is committed to keeping packs interoperable with the wider standards stack.

Use them to compress the front of a deal: from instruction-to-instruction speed for agents, from instruction-to-completion speed for conveyancers, and decision-ready files for lenders and underwriters.

12 data domains — one pack, everything you need to qualify a UK address

Each domain is reconciled, source-attributed and version-stamped — so downstream consumers know exactly which dataset version they’re reading.

Address & UPRN

Canonical UK address, UPRN, USRN, postcode-derived geography.

Tenure & ownership

Freehold/leasehold, title number, ownership chain where public.

AVM valuation

PDI AVM + comparable-led range, confidence band, last-sold price.

EPC & energy

Current and potential rating, kWh/m², recommendations.

Council tax

Band, billing authority, annual charge.

Flood risk

EA flood-zone, surface-water, groundwater and historical incidents.

Planning

Applications within 1km, decisions, appeal status.

Comparables

Recent sold prices, asking-to-sold deltas, time-to-sell.

Demographics

Output Area indicators, tenure mix, household composition.

Connectivity

Broadband speeds, mobile coverage, transport links.

Schools & amenities

Catchment schools with Ofsted, GP surgeries, retail proximity.

Material info

BASPI v5 fields: parts A/B/C — ready for agent listings.

Open, trusted property data is the foundation for a faster, fairer UK property market — one where consumers, conveyancers and lenders all work from the same source of truth.

How to consume

Three ways to put PDI packs into your workflow

Pick the integration depth that fits — from a 1-line embed to full programmatic consumption.

1. REST API

JSON over HTTPS, OAuth2, paginated where relevant. Production-grade SLAs. Built for agents, lenders and PropTech platforms.

2. Embed widget

Drop a single <script> tag into your site or CRM. Branded, responsive, GDPR-safe. Great for agency websites.

3. White-labelled PDF

Branded PDF for buyer / vendor packs and lender files. Auto-generated, version-stamped, BASPI v5 aligned.

One pack, three audiences — three different wins

External recognition matters most when it translates into something tangible for the people who use PDI every day.

Estate agents & portals

Material information ready at instruction, listing-grade pack in seconds, fewer fall-throughs from misrepresented or missing data.

Conveyancers & LSSA firms

BASPI v5 + PDTF v3.5.0 input that drops straight into your case-management system — no re-keying, fewer enquiries, faster exchange.

Lenders & underwriters

Decision-ready, governed property file with full source attribution and version stamps — designed for risk and audit.

Built on standards you already trust

PDI packs are intentionally built on the standards your conveyancing, lending and registry partners are converging on — not a proprietary schema.
