Ecologist licences for protected species survey work

If your site has bats, great crested newts, dormice or badgers on it, the person surveying for them needs a licence from Natural England, and an ecologist licence for protected species survey work is not a general qualification. It is specific to the species, to the methods used and to the named person holding it. A survey carried out without the right licence is worth nothing to your planning application and may itself be an offence, so checking the licence before you appoint is five minutes that saves a season.

What a survey licence permits

Most protected species work would be unlawful without a licence. Handling a bat, entering a roost, disturbing a great crested newt, setting traps for reptiles or using an endoscope in a crevice are all activities the Wildlife and Countryside Act 1981 and the Conservation of Habitats and Species Regulations 2017 make offences unless authorised.

A survey licence authorises those activities for the purpose of finding out what is present. It does not authorise anything that harms the species or its habitat as part of your building works. That is a separate consent, and confusing the two is the single most expensive mistake on a small development.

Plenty of ecological work needs no licence at all. A walkover to assess habitat, a daytime inspection of a building from the outside, a preliminary roost assessment carried out without entering a roost, and bat activity surveys using detectors from the ground are all unlicensed activities. That is why an ecologist can usually get started quickly, then tell you that the next stage needs a licensed surveyor and a particular month of the year.

Class licences and registered consultants

Natural England runs two routes. An individual can hold a personal licence issued for named species and methods, or a consultant can register under a class licence, which is a standing authorisation covering defined activities that anyone registered may rely on.

Bats have a tiered class licence structure. A consultant registers at the level that matches the methods they use, with the higher levels covering more intrusive work such as handling, entering roosts and using endoscopes. A surveyor registered at the lowest level cannot lawfully do the work a higher level permits, which is the detail that gets overlooked when a firm sends a junior ecologist to a job.

Registration numbers are published, so you can ask for the registration reference and the level. Any consultant who is uncomfortable providing it is telling you something.

Licensing species by species

The licensing regime is not uniform, and neither are the seasons. The table below summarises the shape of it for the species most often encountered on small residential sites.

Reptiles are the useful exception. Common lizard, slow worm, grass snake and adder are protected from killing and injury but not from disturbance in the same way, so refugia surveys need no licence. That does not make them less important to your application.

Botanical and invertebrate work has its own rules, and a few rare species carry their own licensing. Ask rather than assume.

Checking a licence is current and covers the method

Four checks take a few minutes and remove almost all the risk.

1. Ask for the licence or registration number and the expiry date, and note that a registration lapses if it is not renewed.
2. Check the species listed on it against the species on your site.
3. Check the methods. A licence that covers observation from outside a building does not cover entering the roof void.
4. Check who is attending. Licences are personal, and accompanied assistants may only work under direct supervision of the licence holder, who has to be present.

Membership of a professional institute is a separate matter from licensing, and both matter. A chartered ecologist who is not licensed cannot lawfully handle a bat, and a licence holder with no professional membership is not bound by a code of conduct. The meaning of that distinction across planning legislation is set out in the note on what competent person means.

Survey validity is the other thing to establish at the outset. Ecological data ages, and councils commonly treat survey results as needing updating after a period that varies with the species and the site, a question covered in the guidance on checking whether a survey is still valid.

Mitigation licences are a separate consent

Where the survey finds a protected species that your works will affect, you need a mitigation licence before those works can lawfully proceed. For European protected species such as bats, great crested newts and dormice, Natural England can only grant one where three tests are met: the work is for a purpose of overriding public interest or for public health and safety, there is no satisfactory alternative, and the population will remain at favourable conservation status.

Timing matters more than people expect. Natural England will normally only issue a mitigation licence after planning permission has been granted, because the licence has to be tied to an approved scheme. So the sequence is survey, then application with a mitigation strategy, then permission, then licence, then works, and each step has its own lead time.

Two schemes shorten this. A low impact class licence covers small scale bat work where the impact is limited, and a registered consultant can use it without a bespoke application. District level licensing for great crested newts lets a developer pay into a strategic habitat scheme instead of carrying out site by site mitigation, which can remove a whole survey season from the programme. Ask whether either applies before you commission a full survey suite.

Badgers sit under their own legislation, with licences issued for interference with a sett and a closed season during which sett closure is not permitted.

What an unlicensed survey is worth

Nothing, for planning purposes, and potentially worse than nothing. A council validating an application with an ecology report will check who carried out the survey. A report describing a roof void inspection by someone with no bat licence tells the officer that an offence may have been committed, which puts the applicant in an awkward position and puts the report in the bin.

The evidential problem is just as real. Unlicensed survey work tends to use the wrong methods at the wrong time of year, and the conclusion that no bats are present carries no weight if the survey could not have detected them. You then pay twice and wait for the season to come round again.

Protected species surveys are one of the report types where a licensed professional is legally required. PlanScope can draft the supporting planning documents around the ecology work and structure the narrative, and the survey itself has to be carried out and signed by a licensed ecologist, who reviews the draft before it is submitted. The professional directory is the route to that review.

Questions to ask before you appoint

Ask what licences the surveyor holds and at what level, which species they cover, and who will actually attend the site. Ask what the survey window is for your species and what happens to the programme if you miss it. Ask whether a preliminary ecological appraisal comes first and what it will cost, because that appraisal usually determines whether you need anything further.

Then ask two questions people forget. What happens if the survey finds something, and what would the mitigation strategy look like. And who will be available to answer the council's ecologist during determination, because an application with an unresponsive consultant drifts.

Finally, ask for the cost of the whole sequence rather than the first stage. A preliminary appraisal is inexpensive. A summer of emergence surveys, a mitigation strategy and a licence application is a different order of commitment, and knowing that at the outset lets you plan the build around the ecology rather than the other way round.

Enter your postcode on PlanScope to see which reports a site with possible protected species is likely to need.

This is general guidance, not legal advice; check the position with your local planning authority or a qualified professional before relying on it. Protected species survey work is legally restricted to suitably licensed ecologists, and a PlanScope draft is a starting point for that professional rather than a substitute.
