Data

Where Senra Radar gets its data

Every source Radar aggregates, with the publisher, the refresh cadence on our side, and the inherent publishing lag on theirs. If a source is stale upstream, Radar cannot make it fresher: we say so here rather than hide it.

By Alfred Afriyie,5 min read(updated 19 April 2026)

Radar does not generate data. It aggregates eleven public data sources, clips them to the exact ward polygon using Office for National Statistics boundaries, and re-reads each source every six hours. The full source list is below, with the honest lag on each.

“Lag” below means the gap between an event happening in the real world and it appearing in the source data. Radar cannot close that gap — it is inherent to the publisher’s workflow. Where lag is long, we say so. Where a source is near real time, we say that too.

Planning applications

FieldDetail
PublisherEach council’s planning portal (typically IDOX, sometimes Objective, Northgate, or bespoke)
What we pullApplication reference, address, description, status, decision, key dates, applicant where public
Radar refreshEvery 6 hours
Upstream lagUsually less than 24 hours from validation to portal. Decisions take longer: committee cycles are fortnightly or monthly.
Known limitationsSome older applications have incomplete fields. Addresses are not always geocoded; where they are not, the application may fall outside our polygon-clip check and be excluded from ward view.

Street issue reports

FieldDetail
PublisherFixMyStreet, operated by mySociety
What we pullReport category, location, status, opened date, closed date where available
Radar refreshEvery 6 hours
Upstream lagNear real time on creation. Closure status depends on the council updating FixMyStreet, which varies from hours to never.
Known limitationsReports filed directly to the council (not via FixMyStreet) are not included. Categories differ slightly between councils.

Police-recorded crime

FieldDetail
Publisherdata.police.uk, Home Office
What we pullCrime category, approximate location (snapped to a street-level anchor), outcome, month
Radar refreshMonthly, when a new release drops (typically mid-month)
Upstream lag4 to 8 weeks. A crime in March appears in the April or May release. This is a real constraint and it is not something Radar can improve.
Known limitationsLocations are intentionally blurred to the nearest anchor point for privacy. Exact addresses are not in the public feed and Radar does not have them either.

Residential property sales

FieldDetail
PublisherHM Land Registry, Price Paid Data
What we pullAddress, sale price, sale date, property type, tenure (freehold or leasehold), new-build flag
Radar refreshMonthly
Upstream lagUsually 1 to 3 months from completion to publication. Slow conveyancers push this out further.
Known limitationsCommercial transactions and bulk purchases are excluded from Price Paid. Some addresses lack coordinates and are excluded.

Food hygiene ratings

FieldDetail
PublisherFood Standards Agency
What we pullBusiness name, address, rating (0 to 5), last inspection date, business type
Radar refreshWeekly
Upstream lagA new rating appears within a few weeks of inspection. Between inspections (which can be 6 to 24 months apart) the rating does not change.
Known limitationsHygiene rating reflects one visit: it is a snapshot, not a trend line.

Energy Performance Certificates (EPC)

FieldDetail
PublisherDepartment for Levelling Up (now MHCLG) EPC register
What we pullAddress, EPC band (A to G), energy efficiency score, certificate date, property type
Radar refreshMonthly
Upstream lagA new EPC appears within weeks of issue. Most EPCs are valid for 10 years, so the register skews old.
Known limitationsA certificate can be up to 10 years old and still show as “current.” Improvements made since the last EPC will not be reflected.

Stop and search

FieldDetail
Publisherdata.police.uk, Home Office
What we pullApproximate location, date, self-defined ethnicity, legislation used, outcome
Radar refreshMonthly, alongside crime data
Upstream lagSame as crime data: 4 to 8 weeks.
Known limitationsLocations are blurred the same way crime locations are. Not every force uploads stop and search data with the same completeness.

Road traffic accidents

FieldDetail
PublisherDepartment for Transport, STATS19
What we pullLocation, date, severity (slight, serious, fatal), vehicle and casualty counts, conditions
Radar refreshAnnual, when DfT publishes the STATS19 release
Upstream lagSignificant: the DfT release for year N typically lands the following summer. A crash in January 2026 will appear in mid-2027.
Known limitationsThis is the longest-lag source in Radar. It is useful for long-run pattern analysis, not for recent incidents. If you need recent accident data, contact your council’s road safety team directly.

Companies House registrations

FieldDetail
PublisherCompanies House (UK government)
What we pullCompany name, registered office address, status (active / dissolved), incorporation date, SIC industry code
Radar refreshEvery 6 hours
Upstream lagUsually less than 24 hours from filing to public register entry. Same-day on time-sensitive filings.
Known limitationsFree Companies House data covers the registry only. Detailed accounts and director histories sit behind the paid Companies House API and are not aggregated here.

Parliament petitions

FieldDetail
PublisherUK Parliament e-petitions service
What we pullOpen petitions with their signature counts broken down by parliamentary constituency, mapped to ward via constituency boundaries
Radar refreshEvery 6 hours
Upstream lagNear real time on signature counts; small delay on government-response and threshold events.
Known limitationsParliament publishes signature counts by constituency, not by ward. Ward-level numbers are inferred via constituency-to-ward mapping; expect minor distribution noise where wards span constituency boundaries.

Road works and street works

FieldDetail
PublisherDepartment for Transport Street Manager — mandatory submission system for utility companies and highway authorities
What we pullPermits + activities: location, start and end dates, traffic management type, highway authority, work category
Radar refreshReal time via SNS push notifications, with a six-hourly poll as a fallback
Upstream lagTypically less than 24 hours from utility scheduling to register publication. Varies by authority compliance.
Known limitationsEngland statutory road works only. Authorities that submit irregularly will show gaps; we surface what Street Manager publishes.

What Radar does not have

Equally important: a few things councillors ask about that Radar does not pull, and why.

  • Council meeting agendas and minutes. Modern.Gov already covers this well. See our Modern.Gov comparison.
  • MP voting records and Hansard. TheyWorkForYou is the right tool. Radar covers local, not national.
  • Parish council minutes. No consistent national publishing format exists.
  • Real-time police incident data (999 calls). Not publicly published by any force. What you see on Radar is police-recorded crime, which is a different, slower dataset.
  • Resident casework notes. Radar does not ingest anything that residents share with councillors privately. That stays with you.

Boundaries

Every record above is clipped to the ward polygon from the Office for National Statistics statistical boundaries, not a postcode approximation. When the LGBCE (Local Government Boundary Commission for England) redraws boundaries after a review, we update within one release cycle.

This matters because postcode sectors straddle wards. A FixMyStreet report filed from a postcode that sits in two wards will appear in Radar for the ward the actual point lies in, not both.
