Badger licensing and who applies for it

A badger sett cannot be interfered with for development without a licence from Natural England, and that licence is usually applied for after planning permission has been granted, not before. The Protection of Badgers Act 1992 protects the animal and the sett separately, so a scheme can be lawful in planning terms and still be a criminal offence to build. For a rural owner planning a barn conversion, an access track or a paddock development, the badger licence development sequence is the part of the programme most likely to cost a season.

What the legislation protects

The 1992 Act creates two groups of offences that matter on a development site.

The first group concerns the animal: killing, injuring or taking a badger, or attempting to do so, and cruel ill-treatment. The second concerns the sett: damaging or destroying it, obstructing access to it, causing a dog to enter it, and disturbing a badger while it is occupying a sett.

That second group catches far more development than people expect. Obstructing an entrance with spoil, running a tracked excavator within the zone of influence of a tunnel system, or storing materials over a disused entrance all fall within it. Disturbance does not require physical damage.

Badgers are protected under domestic law rather than as a European protected species, so the three derogation tests that govern bat and great crested newt licences do not apply here. The licensing judgement is different, and advice written for bats transfers badly.

Survey competence and timing

Badger surveys are not themselves licensable, which means anyone can walk a site and record field signs. That is precisely why the quality varies so much.

A competent badger survey identifies setts, classifies them by use, maps entrances and spoil heaps, records latrines, runs, snuffle holes, hair on fences and bedding, and sets out the likely territory. Classification is the skilled part: a main sett with breeding use is treated very differently from an outlying sett used occasionally. Getting that wrong turns a straightforward licence into a refused one.

Field signs are clearest between late autumn and early spring when vegetation has died back, which is also when a licence cannot be exercised. Survey in winter, apply in spring, work in summer is the rhythm that fits the law. Camera monitoring over several weeks is often needed to confirm whether an entrance is in current use.

Commission the work from an ecologist with badger experience who will put their name and a date on the report. A Protected Species Survey is one of the report types where a suitably licensed and experienced professional is legally required, under the Wildlife and Countryside Act 1981 and the habitats regulations for European species, and expected as a matter of competence for badgers. An AI-assisted draft gives that professional a structure to work within rather than replacing their field judgement.

Who applies for a licence and when

Natural England issues the licence. The application is normally made by or on behalf of the person responsible for the works, with the surveying ecologist named as the person who will carry out the sett closure and supervise the works.

Two preconditions shape the timing. Natural England expects the development to have planning permission before it will grant a development licence, because the licence authorises interference for a defined scheme. And it expects the mitigation to be designed, which on sites with a main sett means an artificial sett already built and in use.

That ordering is the trap. An applicant who treats the licence as a post-decision formality discovers that the artificial sett should have been constructed the previous summer. Our note on why every planning report needs a named author and date is relevant here, because Natural England will read the badger report as evidence and an undated anonymous survey carries little weight.

Closure seasons and their limits

Sett closure is normally licensed only outside the badger breeding season, which in practice means a working window running from 1 July to 30 November. Natural England does not usually authorise closure between 1 December and 30 June because of the risk of dependent cubs underground.

The window is five months, and it is shared with every other developer in the county. Ecologists with badger experience book up. If your permission issues in September and the closure needs a one-way gate period before exclusion is confirmed, the realistic start on site is the following July.

Artificial setts and monitoring

Where a main sett is to be lost, a replacement has to be provided and shown to be acceptable to the animals before the original is closed. Artificial setts are engineered structures with chambers, tunnels and bedding, built in a location with suitable soil, drainage, cover and access to foraging territory.

They take time to be adopted. The licence will set out a monitoring regime, usually camera-based, and closure of the original sett cannot proceed until the replacement shows use. Budget for monitoring across a full season rather than a few weeks.

Where only an outlying or subsidiary sett is affected, closure may be licensed without a replacement, which is why accurate classification at survey stage changes the cost of the scheme by an order of magnitude.

Where works must stop

Instruct the site team on three stopping rules before work starts.

1. If a previously unrecorded entrance is found, stop work in that area and call the ecologist. New setts appear between survey and construction, and the licence does not cover them.
2. If badger activity is recorded inside an area already excluded, stop and have the exclusion re-verified. Reopening happens.
3. If the licence conditions on timing, supervision or method cannot be met, stop rather than improvise. Working outside licence conditions removes the defence the licence provides.

Put those rules in the construction method statement so they bind the contractor, and brief the site manager in person. A toolbox talk is worth more than a paragraph nobody reads.

Evidence the authority expects

At application stage the local planning authority wants enough to be satisfied that the scheme is deliverable and lawful. That means a survey report with dates, methods and a sett plan, an impact assessment, an outline mitigation strategy and a clear statement of the licensing route.

The authority may condition a detailed badger mitigation strategy and the appointment of a named ecological clerk of works. It cannot grant the licence and should not condition something the licence will determine, so keep the planning submission focused on deliverability. Where a Preliminary Ecological Appraisal has flagged badger activity, follow it with the species survey rather than arguing the point at committee.

Reviewers with badger and licensing experience can be found through the professional directory if your drafting needs checking before submission. PlanScope provides AI-assisted draft reports for planning applications. Reports should be reviewed before submission. We do not guarantee planning approval. This is general guidance, not legal advice.
