Data Sources
What powers Briefwise today
Briefwise combines source-backed data with research-based characteristics to help you compare areas more systematically.
At a glance
Simple version
- Price data and maps come from government-backed sources.
- Travel is based on average public transport times between areas.
- Neighbourhood character is currently research-based rather than fully source-fed.
1. Prices + map
Government-backed area and price data
Price levels, price histories, and London area shapes are based on official geography and housing datasets. These are the backbone for the map, charts, and budget filters.
2. Travel
Average journey times, not live routing
Travel constraints use average public transport times from academic research. They are based on area centroids, so they are best used for screening and comparison rather than exact door-to-door journey promises.
3. Area character
Research-based characteristics
Things like vibe, schools, community, buzz, calm, and local feel are currently built from structured research and synthesis. They are there to make the tool more useful, but they are still less robust than the core price and geography data.
4. Caveat
What to use this for
Briefwise is best used to build a smarter shortlist and understand trade-offs. It is not yet a live listings platform, route planner, or valuation tool.
- Use it to narrow the field quickly.
- Then do deeper research on the shortlist that remains.
