The work
What Hertsmere's building applications are for, and where.
53% of Hertsmere's 481 building applications in the last 12 months were single-storey extension, then two-storey or first-floor extension (96).
The work clusters in EN6 (151), WD6 (128) and WD23 (85): those three postcode districts filed 76% of it.
Filings ran at about 50 a month over the last 5 full months, peaking in June 2026 with 56.
That is 37% of everything filed with Hertsmere Borough Council in the year (1,312 applications); the rest is other trades' work, adverts, trees and paperwork.

How quickly does Hertsmere Borough Council decide planning applications?
Hertsmere Borough Council decided 91.6% of its applications within the statutory time limit in 2025, and granted 93.9% of its "other" decisions, the government category that holds householder applications (505 of 538, MHCLG PS2 figures). The target for a householder application is eight weeks, so a letter sent the week it is filed lands well before the decision.
Can another builder in Hertsmere get the same list?
Not from us while you hold it. Exclusive cover is one firm per trade per patch, and we check your patch is free before you pay. The register itself is public, so anyone can read it: what you pay for is the reading, the matching, the deduplication and a list your printer can post the same day.
How do I get the addresses?
Subscribe to Demand Radar for £149 a month. Your first list arrives within 24 hours, then only new homes every month, as a CSV your printer or mailing house can run as it is. Addresses are for letters to "The Owner/Occupier" only: no names, no phone numbers.
