Natural England class licences: which one applies

The ecologist class licence types that matter on a development site fall into two families: licences that let someone survey a protected species, and licences that let works go ahead once the species has been found. They are not interchangeable. A surveyor registered to torch and net a pond for great crested newts has no authority to destroy that pond, and a consultant holding a low impact licence for common bats cannot use it on a maternity roost.

Natural England issues both under the Conservation of Habitats and Species Regulations 2017 for European protected species, and under the Wildlife and Countryside Act 1981 or the Protection of Badgers Act 1992 for the species those statutes cover. Which instrument applies is the first question, because it sets the tests, the paperwork and the timing against planning permission.

Why survey work needs a licence at all

Regulation 43 of the 2017 Regulations makes it an offence to deliberately capture, injure or kill a European protected species, to deliberately disturb it in ways listed in the regulation, or to damage or destroy a breeding site or resting place. Disturbance is defined widely enough that ordinary survey methods fall inside it.

Entering a roost with a torch, handling a bat, trapping newts in a bottle trap, using an endoscope in a crevice, lifting refugia to find reptiles, or checking a dormouse nest tube all involve capture or disturbance. Without a licence, those acts are offences, whatever the purpose. The species protected under the Wildlife and Countryside Act 1981 work the same way for the activities that Act prohibits, which is why disturbing a Schedule 1 bird at the nest needs separate authority.

That is also why a Preliminary Ecological Appraisal can be done by any competent ecologist, while the species-specific survey it recommends usually cannot. The appraisal is observation from outside. The survey reaches inside.

What a class licence actually permits

A class licence is a standing licence issued by Natural England that named people may register under, rather than a one-off permission applied for site by site. The licence document sets out the species, the methods, the time of year, the number of animals and the circumstances. Everything outside those limits needs a bespoke licence.

The low impact route is the one most often misused. It exists so that a loft conversion affecting a handful of common pipistrelles does not need a full bespoke licence, and it stops at the point where a roost becomes important for the species. A maternity roost, a hibernation site or an annex species takes the work straight back to a bespoke application.

District level licensing for great crested newts changes the economics rather than the law. Where a scheme sits in a participating area, the developer pays into a strategic scheme and Natural England takes on the habitat delivery, which removes the pond-by-pond trapping programme from the critical path. It does not remove the need for an ecologist to establish what is there.

The registered consultant arrangement

Class licences work through registration. An ecologist applies to Natural England to be added as a registered person, evidences their experience and training, and then acts under the terms of the class licence rather than their own. Registration carries duties: annual returns, record keeping, and compliance reporting on each site.

Two consequences for anyone commissioning or reviewing work. First, the registration is personal, so a firm cannot hold it on behalf of staff. Second, registration can be suspended or withdrawn, which means a licence number quoted from a report written two years ago tells you nothing about today. We look at the wider version of this problem in supervision chains: graduate work signed by a chartered author.

Mitigation licences and the three derogation tests

A bespoke licence under regulation 55 is granted only where three tests are met, and the method statement has to address each one in terms.

1. The purpose falls within a permitted reason, in development cases normally imperative reasons of overriding public interest, including those of a social or economic nature.
2. There is no satisfactory alternative, which means alternative designs, layouts and timings have been considered and rejected on evidence.
3. The action will not be detrimental to the maintenance of the population of the species concerned at a favourable conservation status in its natural range.

Natural England will not normally grant a licence before planning permission is in place, because the public interest and alternatives tests depend on the consented scheme. That ordering catches developers who assume the licence can be run in parallel with determination. It cannot, and the gap between permission and licence is routinely measured in months, not weeks.

The second test is where applications fail. A reasoned statement that asserts no alternative exists, without showing what was tested, is the most common reason for a request for further information.

Recording the licence in the report

A Protected Species Survey report should state, for every piece of licensed work, the licence or registration number, the class licence it was carried out under, the named person who held it, the dates of the survey visits and the methods used against the relevant guidance. A licensed or competent professional is legally required for this work, and an AI-assisted draft is a starting point for that professional rather than a substitute for the survey.

Case officers and ecology consultees check that the methods in the report fall inside the licence conditions. A survey carried out in late September and presented as an emergence survey, or a bottle-trapping programme run outside the permitted window, will be queried whatever the conclusion says. Our note on why every planning report needs a named author and date applies with extra force here, because the licence attaches to the person.

Assistants, supervision and who may do what

Class licences allow accredited agents or assistants to work under the direct supervision of the registered person. Direct means on site and within sight, not available by telephone. The supervision ratio is set by the licence, and exceeding it is a breach even where the work was done competently.

This matters for cost and programme. A single registered ecologist supervising assistants can cover a large pond complex in one evening, which is why the ratio question belongs in the fee proposal rather than in a conversation on the night. Ask who will be on site, which of them is registered, and what the licence permits them to do.

Checking a licence before you appoint

Four checks take about ten minutes. Ask for the licence or registration number and the class licence reference. Ask for the expiry or review date. Ask which species and methods the registration covers, and compare that against the survey you are commissioning. Then ask for the date of the most recent return filed with Natural England.

If any answer is vague, the scope of your appointment is vague too. And if the proposed method sits at the edge of the licence, say so before the survey rather than after, because a survey that cannot lawfully be relied on has to be repeated in the next season. That single mistake has cost schemes an entire year. You can find reviewers who sign off ecological work through the professional directory.

This is general guidance, not legal advice. Check the position with Natural England or a suitably licensed ecologist before relying on it. PlanScope provides AI-assisted draft reports for planning applications. Reports should be reviewed before submission. We do not guarantee planning approval.
