Planning in Waltham Forest
Checked October 2026. Planning policy changes, so we confirm the position for your address before you commit.
As a rule of thumb, houses can generally extend up to 3m at the rear, with anything deeper likely to be too overbearing for neighbours, and dormers above the ridge are not acceptable (Residential Extensions and Alterations SPD, 2010). The guidance is old, so how much weight it now carries should be checked case by case.
SourceA replacement Residential Alterations and Retrofit SPD went out to statutory consultation from 2 February to 16 March 2026 and has not yet been adopted.
SourceA borough-wide Article 4 direction means converting a house (C3) to a small HMO (C4) needs planning permission.
SourceThe borough has 15 conservation areas, and nine of them (including Walthamstow Village, Orford Road and Leytonstone) have Article 4 directions that remove some permitted development rights.
SourceA selective licensing scheme launched in May 2025 and runs until 30 April 2030 in every ward except Hatch Lane, Highams Park North and Endlebury, where homes let to three or more unrelated tenants need an HMO licence.
