How it works
How PropSage works
Authorised data, shown with its source. Analysis that explains itself. People accountable where decisions affect people.
From data to decision
Four steps between a source and your decision.
- 01
Authorised source
Licensed feeds and public datasets, through registered connectors. We do not scrape websites.
- 02
Sourced, dated value
Each value keeps its source, licence, retrieval date, coverage and confidence.
- 03
Explained analysis
Scores and calculations show their drivers, assumptions and anything they could not assess.
- 04
Your decision
You decide, with a regulated professional where you need one.
Principles
Six principles behind every screen
- 01Authorised data only.We use licensed feeds and public datasets such as HM Land Registry, the EPC Register, the Environment Agency, Ofsted and Police.uk. We do not scrape websites.
- 02Every value sourced and dated.Verified facts, estimates and AI assessments are labelled differently. If a source is withdrawn, the value is marked unavailable.
- 03Missing data is flagged, never scored as zero.When we cannot assess part of the Investment Score, we say so and re-weight the rest.
- 04AI that cites its sources.Our assistants answer from PropSage data and documents, cite what they relied on, and say when they do not know. You are always told when you are talking to AI.
- 05People stay accountable.Where a decision affects a person, such as choosing a tenant, a named person makes it, not the software.
- 06Decision support, not advice.PropSage provides information and software, not surveying, legal or financial advice. We introduce regulated professionals through disclosed partners.
Provenance
How values are labelled
Verified facts, estimates and AI assessments are labelled differently. If a source is withdrawn, the value is marked unavailable. When part of the Investment Score cannot be assessed, we say so and re-weight the rest.
Verified
From an authorised source such as HM Land Registry or the EPC Register, with the date we retrieved it.
Estimate
Calculated by a stated model or formula, shown as a range with its confidence.
AI-generated
Written by our assistant from sourced data, labelled as AI and linked to its citations.
Not assessed. What we cannot assess is shown as "not assessed" or "not available". It is never scored as zero.
Partner services
How partner introductions work
PropSage does not give financial, legal, surveying or valuation advice. When you need it, we introduce a professional who does.
- 1You askYou ask for a broker, surveyor, conveyancer or planner when you need one. Nothing is sent before you ask.
- 2We introduceThe partner is named before any details are shared, and you can decline with one tap.
- 3The partner advises youRegulated advice comes from the professional directly. Every introduction is recorded.
