Harrow planning for homeowners
Harrow Council decided 95% of its householder applications that were not prior approvals within 8 weeks in the four quarters to 2026 Q2, and granted 82% of all householder decisions. A planning application there is only half the job, as building regulations follow. Our drawings start at £745.

What the Harrow figures show
Harrow made 917 householder decisions in the four quarters to 2026 Q2, counting prior approvals (our analysis of MHCLG planning application statistics, table PS2).
82% of them were grants, and 95% of those that were not prior approvals were made within 8 weeks (our analysis of MHCLG planning application statistics, table PS2). The period is the statutory one for non-major development (DMPO 2015, article 34(2)(b)).
The Planning Inspectorate decided 320 householder appeals on Harrow decisions between 2021 and 2026, allowing 43% (our analysis of the Planning Inspectorate Casework Database, release 2609).
Planning first, building regulations second
Planning permission answers whether the scheme is acceptable. Building regulations answer whether it will be built safely and to standard. They are decided separately, with different drawings, and a scheme can need both. Our guide to planning drawings versus building regulations drawings explains the split.
If your project is in the roof, a rear dormer raises its own planning questions, and our dormer loft conversion drawings service covers the drawings for it.

Conservation areas in Harrow
Harrow has 31 live conservation-area entries on the national register (our analysis of the MHCLG Planning Data Platform conservation-area dataset, snapshot of 19 Oct 2026). Rights that let you build without an application are narrower there, so confirm your address against the national conservation-area dataset and Harrow Council's conservation area map before you plan an extension. Our conservation area glossary entry explains what the designation changes.
