How LPAs are building effective BNG processes - and what's working

Biodiversity Net Gain (BNG) touches more parts of a Local Planning Authority (LPA) than most teams anticipated. Validation, case management, ecology, monitoring - each stage involves different officers, different judgements, and different timescales. Getting this right isn't about any single team working harder. It's about how the whole process connects.

At Verna, we speak with councils across England every day, and we're seeing clear patterns in how LPAs are approaching their BNG processes. In this article, we share some of the principles that effective LPAs are applying - and how Mycelia supports each one.

Catch problems early

The most effective BNG processes front-load rigour. When validation is thorough, fewer cases arrive at the ecologist's desk with missing information, and fewer determination clocks start ticking on applications that aren't ready.

Several councils have found that involving their ecologist at the validation step - not to review every application, but to flag cases where missing survey information would cause problems later - prevents the wrong cases from reaching determination unprepared. Others run regular ecology drop-in sessions for planners, giving case officers a route to resolve BNG questions without formal referrals.

Mycelia automates the technically complex parts of validation - tampering detection, national checklist compliance, and local list requirements - so validation officers can make confident decisions without needing specialist ecological knowledge. This means ecologists can spend their time on genuine ecological judgement, not checking whether a metric has been filled in correctly.

Uttlesford District Council's validation team now processes BNG checks within their standard five-day turnaround for minor developments, and ten days for majors, with no additional strain on their ecologist or case officers.

Keep ecology and planning aligned throughout

Through the life of an application, ecology and planning teams need to stay connected - on conditions, on Biodiversity Gain Plan requirements, and on whether what's being approved is ecologically credible.

The most common solution we see is simple: regular coordination between ecology and planning leads. One London Borough planning department established a weekly touchpoint after bringing their ecologist and validation lead into a shared session - a rhythm that keeps both teams aligned on outstanding cases and edge decisions.

Mycelia makes this coordination more productive by giving both teams a shared, up-to-date view of every BNG case and its status. Rather than chasing updates across emails and spreadsheets, teams walk into their coordination meetings with the same information in front of them - what's outstanding, what's been conditioned, and what needs reveiw by an ecologist.

Close the loop on monitoring

Monitoring is where most LPAs acknowledge they have the most ground to cover. The challenge isn't just tracking whether habitats are delivered over 30 years - it's knowing which developments have commenced and whether they're proceeding within the terms of their BNG consent.

Several LPAs now receive a monthly commencement report from Building Control, which they cross-reference against approved Biodiversity Gain Plans in Mycelia. Because Mycelia holds the full BNG record for each case - from the original metric through to the approved gain plan - this cross-referencing is straightforward rather than a manual trawl through separate systems. As the volume of cases and information held for monitoring starts to grow, this kind of joined-up working between development management and building control is becoming essential.

Building a process that holds together

Each of these principles - front-loading validation, keeping teams aligned, closing the monitoring loop - delivers value on its own. Together, they create a BNG process where decisions made at each stage carry through to the next.

Mycelia is the platform that makes this sustainable. It automates the checks that would otherwise consume specialist time, gives every team a shared view of BNG cases across the full planning process, and ensures that the data created at validation is still available and usable when monitoring begins years later. The result is a process that scales with caseload rather than depending on individual officers holding everything together.
