By trade
Planning leads in Hertsmere, trade by trade.
Hertsmere Borough Council took 1,312 planning applications in the 12 months to 21 Oct 2026. 839 of them (64%) 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, Hertsmere's register favours windows & doors (598), roofing (517) and builders & bricklayers (481): one application usually means work for several trades, so these overlap.
The most active postcode districts are EN6 (244), WD6 (217) and WD7 (140).
About 90 trade-relevant applications a month over the last 5 full months, peaking in August 2026 with 96.
