Know who lives at a postcode before you sign a lease.

Site selection decisions that used to require a market research agency can now be answered from a postcode. Zyfy returns deprivation decile, median property price, liveability score, rural/urban classification, and broadband coverage in a single call — the location intelligence a retail team needs to shortlist sites, brief store managers, or evaluate a franchise territory without a bespoke data project.

Relevant signals

These fields are returned on every response and are ready to wire into your application logic.

SignalRelevanceWhat it tells you
signals.deprivation.imdDecileCriticalIndex of Multiple Deprivation decile 1–10. 1 = most deprived. The single most predictive demographic signal at postcode level. Drives footfall expectations, price point assumptions, and product range decisions.
signals.property.averagePriceCriticalMedian residential sale price in the last 12 months from HMLR. Strong proxy for purchasing power when you do not have income data. Pairs with IMD to separate high-income low-deprivation areas from high-price low-turnover ones.
scores.liveabilityScoreHigh0–1 composite of air quality, crime, deprivation, green space proximity, and EPC efficiency. Summarises neighbourhood desirability in one number — useful for comparing shortlisted sites without reading five separate signals.
ruralUrbanClassificationHighFive-tier ONS classification from urban through rural hamlet. Affects footfall model, opening hours, product range, delivery logistics, and staff availability — not just a flag, a whole operating context.
signals.broadband.gigabitMediumGigabit broadband availability. Relevant for any site that will run cloud-dependent systems — increasingly a baseline requirement before lease commitment.
scores.affordabilityIndexMedium0–1 score where 1 = cheapest nationally. At 0.02, a central London postcode is telling you this is a premium location — frame your site economics accordingly.
signals.demographics.percNoCarVanMediumPercentage of households with no car or van from the census. Directly relevant to motor insurance penetration and fleet pricing — a low car-ownership area means fewer motorist customers and different risk profiles.
signals.housing.councilTaxBandMediumCouncil tax band estimate. lower/upper give the band range; source indicates data origin. source: "exact_nrs" for Scotland (authoritative NRS data); "derived_hmlr" for England and Wales (HMLR prices + ONS regional HPI deflation). Useful for home insurance premium banding and property value tier segmentation.

What you get

  • Replaces a morning of manual research per site — Pulling deprivation data from ONS, house prices from HMLR, and rural classification from another ONS file takes time. One API call returns all of it in a consistent format.
  • Consistent scoring across your shortlist — scores.liveabilityScore lets you rank fifty candidate sites on the same scale. No subjective weighting, no spreadsheet errors, no analyst time spent normalising sources.
  • Works at any scale — Screen a single prospect site in a tool, or batch-enrich a national property list via the bulk endpoint. Same data, same format, same endpoint.
  • Feeds existing location intelligence tools — Return structured JSON that maps cleanly into GIS platforms, BI dashboards, or property management systems. No transformation layer needed.
