Protected Species Survey
After bats and great crested newts, the species councils ask about most are reptiles, badgers and nesting birds, with otters, water voles and dormice on sites near rivers and woodland. A preliminary ecological appraisal will usually say which, if any, your site needs.
Each has its own season and method, and some need a licence before work can go ahead. Here is what each involves.
- Badger survey
- £350 to £900plus VAT, most months
- Reptile survey
- £2,000 to £4,000plus VAT, April to September
- Breeding birds
- £800 to £1,200plus VAT, March to August
1Reptiles
Slow worms, common lizards, grass snakes and adders are protected from being killed or injured under the Wildlife and Countryside Act 1981, and the rare sand lizard and smooth snake are fully protected. Natural England tells councils to ask for a survey where records or suitable habitat suggest reptiles may be present (gov.uk).
Rough grassland, scrub edges, railway banks, allotments and brownfield land with rubble are typical. The survey places sheets of roofing felt or tin across the site and checks under them about seven times between April and September, in warm but not hot weather.
If reptiles are found, the usual answer is to move them to a prepared area of the site or nearby before work starts, which adds time in the active season.
2Badgers
Badgers and their setts are protected under the Protection of Badgers Act 1992. Councils ask for a survey where badgers are known to be active or the site has suitable sett or feeding habitat, and Natural England notes that the absence of records does not mean there are no badgers (gov.uk).
A survey searches the site and its edges for setts, paths, latrines and digging, and judges whether any sett is in use. It can be done for most of the year, and is often easiest from late winter into spring before vegetation grows.
If a sett would be damaged or badgers disturbed, a licence from Natural England is needed. There is no fee, a licence is normally issued only after full planning permission, and setts are usually closed only between July and November (Planning Portal).

| Species | When a survey is likely | Season | Typical cost |
|---|---|---|---|
| Breeding birds | Hedges, scrub, trees or buildings to be cleared | March to August | £800 to £1,200 |
| Barn owls | Barn and agricultural building conversions | Any time for signs | Often part of a bat survey |
| Otters and water voles | Work beside rivers, streams and ditches | April to October | From about £900 |
| Dormice | Hedgerow or woodland removal in southern and central England | April to November | From about £2,000 |
Vegetation clearance during the bird nesting season is the most common issue on small sites. Where it cannot be avoided, an ecologist checks immediately before clearance and work stops around any active nest until the young have left.
Questions we get asked
Which species survey do I need?
The preliminary ecological appraisal will tell you. If the council has asked for a specific survey, choose that one on the form. If you are not sure, start with a PEA.
Can reptile surveys be done in winter?
No. Reptiles hibernate, so surveys run from April to September. In winter the ecologist can set out where the survey sheets will go and plan the timetable.
Do I need a licence to close a badger sett?
Yes, from Natural England, and normally only after full planning permission. Licences are free, and sett closure is usually limited to July to November.
Can I clear hedges in spring if I check for nests first?
Only with great care. All active wild bird nests are protected. Most ecologists advise clearing between September and February, and checking immediately before any clearance in the nesting season.

Three short steps: where the site is, what you are planning, and how to reach you. About two minutes. If the council named a survey in a letter or validation checklist, choose that one.
Thank you. We have your enquiry.
- We will email or phone, normally within one working day, with the name of an ecologist who covers your area and the surveys you need.
- If you are happy for them to have your details, we pass them on. If not, nothing is shared.
- The ecologist confirms the scope, the season and the fee in writing. We send no marketing.
