About these figures

The figures describe decided applications for one to nine homes. They show what has happened in Waltham Forest over the period covered; they do not predict the outcome of an individual application, and no approval probability is offered for any site or scheme.

Sample sizes are shown with the findings. Where the available evidence is too thin for a result to carry meaning, it is withheld or marked accordingly.

Data sources & method

Applications. Sourced from the Greater London Authority (GLA) Planning Datahub and Waltham Forest Council’s online planning register. Covers full planning, householder, and minor residential applications of nine units or fewer decided in the window shown above.

Decisions and timing. Outcomes and determination times are taken from the council’s published decision notices.

Refusal reasons. Extracted from refused decision notices that were publicly available. Not every refusal has a readable notice, so totals count all refusals but the reason breakdown covers only those we could read.

Scheme classification. Site types (conversion, demolish & rebuild, extension, and so on) are coded from application descriptions and drawings. Areas are mapped from postcodes and ward names using the council’s own sub-area definitions.

Update frequency. Refreshed quarterly. Next refresh: October 2026.

Nothing here is planning advice. Outcomes are historical and do not predict individual cases. Approval rates vary with site specifics, policy context, and case officer. See our Terms of Use for full details on how this data is compiled and the limits of its use.
