That ranks Hounslow 117 of 195 English councils with at least 20 appeals decided, counting from the most often overturned.

What this means if you are objecting

Roughly one appeal in three succeeds here, as across England. A refusal is not the end of the matter, so an objection grounded in the adopted local plan is worth more than one that is not, because the same policies are what an inspector would weigh.

Householder appeals

68 householder appeals were decided against Hounslow, with 68% allowed. These are extensions, loft conversions and the like, and they are decided under a faster procedure than a full planning appeal.

Against the rest of London

Across London, inspectors allowed 25% of planning appeals on average. Hounslow is a london borough.
