Planning a renovation in the Thames Valley? Understanding the ecological calendar is the difference between a summer build and a twelve-month delay.
"The Planning Officer says they can't determine the application because of a potential bat roost." If you hear these words in October, your project is likely frozen until the following May.
Bats are a protected species. Under UK law, it is a criminal offence to disturb a roost, even unintentionally. If a Planning Officer identifies "reasonable likelihood" of bats—due to your home's age, proximity to woodland, or roof structure—they cannot legally grant permission without a survey.
Emergence surveys can only be carried out when bats are active: between May and September. If your application hits a snag in the autumn, you cannot "buy" your way out of it—you simply have to wait for the next season.
We treat ecology as a "Day One" constraint. We don't wait for the council to ask; we anticipate the requirement so the clock never stops.
We identify "high risk" rooflines during the first site visit, allowing us to book ecologists months in advance.
If a survey is flagged late, we negotiate a legal "Extension of Time" to keep your application live, avoiding a flat refusal.
