What Harrow's recent decisions show
Those 917 householder decisions include prior approvals. Of the householder applications that were not prior approvals, 95% were decided within eight weeks, so the large majority were settled inside the statutory period. Across every type of application the council made 1,362 decisions in the same four quarters.
The figures are our analysis of the government's planning application statistics, table PS2, released on 24 September 2026. They describe a period that has already ended. They do not promise a result for your scheme, and a well-drawn application is only one of the things a decision turns on.
When a refusal is appealed
Applicants who are refused can appeal to the Planning Inspectorate. Our analysis of its Casework Database finds 320 Harrow householder appeals decided between 2021 and 2026, and 43% of them were allowed. Read that as history: it shows appeals are a real option, not that yours would succeed.
Most owners would rather avoid the appeal. That is the argument for getting the existing survey and the proposed drawings right before anything is submitted.

Conservation areas and the council's own map
Our analysis of the Planning Data Platform counts 31 conservation-area entries on the national register for Harrow. The register is a guide to what exists rather than a boundary tool. Before you plan, check your street on Harrow Council's own conservation area map, and tell us if it falls inside one, since that can add requirements to the application.
The register's data comes from the government's planning data platform.
What goes into a Harrow application
A valid application needs plans drawn to an identified scale, with north shown. The location plan should typically be at 1:1250 or 1:2500. Beyond that, Harrow Council can ask for further information through its own local list, so the exact set can differ from a neighbouring borough's.
Our starting fee of £745 for householder planning drawings includes the design statement and the submission as well as the survey and the drawings. The council's application fee is paid on top, and you can see the rest of our prices on the pricing page. If you are weighing up the route first, how long planning permission takes in London sets out the timeline, and planning permission in Harrow shows the borough from the permission side.
Before you commission drawings
If the project is modest, such as a rear extension within permitted development, a lawful development certificate may be all you need; see lawful development certificate drawings. If the layout of the house has never been recorded, a measured floor plans survey for Harrow gives you the existing drawings.
