About notbad

notbad is the public name of the London Good Areas mapping project. It is built for two practical tasks: shortlisting places in Greater London around your own requirements, and checking the surroundings of a home you have already found elsewhere.

What the project contributes

The map brings saved noise evidence, walking access and local records together in one browser-based tool. Explore keeps only places meeting every enabled condition. A separate postcode report shows all ten checks independently, with no combined property score. The methodology explains the sources, calculations and uncertainty.

The 33 area guides add reproducible examples from public reference positions. Their tables are generated from the same report engine as the map. Their images show the retained local basemap with an official borough outline and numbered examples. They are not photographs, site visits or surveys.

Project attribution and independence

Content and calculations are attributed to the notbad project. Individual creator details have not been supplied for this local edition. The project does not claim endorsement by Defra, TfL, Police.uk, ONS, DfE or Ofsted; those organisations publish the source material identified beside the evidence.

The site does not list properties or establish their price, condition, admissions eligibility, indoor noise or personal safety. It has no accounts, application backend or external analytics. The map and report run from packaged files in your browser. Source links open the original publishers' websites.

Report a problem with this local edition

Send the following details to the person who provided your local copy of notbad. A public contact address has not yet been configured, so this edition does not offer a working public submission form.

• The page URL and the date you noticed the issue.
• The borough guide and numbered example, or the criterion involved.
• What you expected and what the page actually showed.
• A source link or screenshot when it helps explain the discrepancy.
• Whether the issue concerns a source record, an estimated route, the explanation or the interface.

Do not include a private property address or postcode unless you deliberately choose to share it with that recipient. A public guide's example number is enough to identify its retained evidence. Problems in source records may also need to be reported to the original publisher; the sources and method page links to them.

How content is reviewed

Each guide records its own editorial review date. Source dates are listed separately, because a recently reviewed explanation can describe older mapping or activity. Area examples retain their source IDs, coordinates and calculation evidence in the development project so they can be regenerated when those inputs change.
