By trade
Planning leads in Hillingdon, trade by trade.
Hillingdon Council took 1,042 planning applications in the 12 months to 21 Oct 2026. 764 of them (73%) mean work for at least one trade; the rest are adverts, trees, conditions and paperwork, and they never reach a list.
Of the main building trades, Hillingdon's register favours windows & doors (603), roofing (567) and builders & bricklayers (466): one application usually means work for several trades, so these overlap.
The most active postcode districts are HA4 (106), UB3 (63) and UB10 (55).
About 136 trade-relevant applications a month over the last 5 full months, peaking in July 2026 with 181.
Applications that mean work, last 12 months
