Protected species surveys
How much does a bat survey cost?
A preliminary roost assessment, the first survey most projects need, typically costs £250–£500 and can be done at any time of year. If it finds potential roost features, dusk emergence or dawn re-entry surveys follow at £350–£600 each, with one to three usually required, and those can only run in the May to September season, which is why timing so often drives project delays. All figures are typical 2026 quotes; tell us about your project and licensed ecologists covering your area will quote their exact fee.
Typical bat survey costs, 2026
Last updated
How much is a bat survey in the UK? The cost of a bat survey depends on which stage your project needs, and each stage is priced below. These are typical quote ranges observed across the market in 2026, not fixed fees; travel distance, building size and the number of surveyors required move quotes within and beyond these ranges.
Ranges reflect typical 2026 quotes for bat survey work on domestic and small development projects across the UK; fees vary by region, building complexity and the number of surveyors a visit needs. The combined figure is the sum of a PRA (£250–£500) and two emergence surveys (£350–£600 each). Mitigation licence costs are project-specific and quoted per job, so no reliable typical range is stated. Get exact quotes for your site via the form above.
| Survey stage | Typical cost (2026 quotes) | Notes |
|---|---|---|
| Preliminary roost assessment (PRA / scoping survey) | £250–£500 | Daytime inspection, any time of year; often the only survey needed |
| Dusk emergence or dawn re-entry survey | £350–£600 each | May to September only; 1–3 visits commonly required depending on roost suitability |
| PRA plus two emergence surveys (common house-project package) | £950–£1,700 | The arithmetic of the two rows above; larger buildings need more surveyors per visit |
| Bat mitigation licence support (if a roost is affected) | Quoted per project | Ecologist fees for licence application and method statement; Natural England, NRW or NatureScot also charge for some licences |
| European Protected Species licence application (where a roost is affected) | £1,000–£2,500 | Only where works will affect a roost; prepared by the ecologist and submitted to the licensing body |
- The typical preliminary roost assessment cost is £250–£500 in 2026 UK quotes, and the survey can be carried out at any time of year.
- Dusk emergence and dawn re-entry surveys typically cost £350–£600 each, with one to three visits commonly needed, and can only be done in roughly May to September.
- A common package for a house project, one PRA plus two emergence surveys, totals £950–£1,700 at typical 2026 quotes.

Questions, answered directly
How much does a bat survey cost?
Typical 2026 UK quotes: £250–£500 for a preliminary roost assessment, and £350–£600 per dusk emergence or dawn re-entry survey where those are needed, with one to three visits common. A typical house project needing a PRA and two emergence surveys totals £950–£1,700. Fees vary by region and building complexity.
Why are bat surveys required at all?
Because bats and their roosts are legally protected under the Conservation of Habitats and Species Regulations 2017 and the Wildlife and Countryside Act 1981, and councils must take that protection into account before granting permission for works that could affect them. The survey provides the evidence that lets a lawful decision be made.
What happens if bats are found?
Usually the project proceeds with conditions rather than stopping: works affecting a roost need a mitigation licence from Natural England (Natural Resources Wales in Wales, NatureScot in Scotland), typically with timing constraints and replacement roost provision designed by your ecologist. It adds cost and calendar time, which is another reason to survey early.
Can I skip the survey if I've never seen a bat?
Not safely. Roosts are protected even when bats are absent, damaging one can be an offence regardless of intent, and a council faced with a building that could plausibly hold roosts will require evidence either way. A preliminary roost assessment, typically £250–£500, is the inexpensive way to answer the question properly.
When can bat surveys be done?
Preliminary roost assessments run year-round. Emergence and re-entry surveys run roughly May to September, with May to August optimal, so a project that discovers the requirement in autumn typically waits until the next season. Timing, more than fee levels, is what bat surveys cost most projects.
Is this quote service really free?
Yes, free to you, with no obligation to accept any quote. We pass your details only to relevant licensed ecologists, who quote you directly; we may receive a fee from those providers, which is how the service is funded.

- Bat survey for planning permission: when it's required and what it costs
Councils must consider protected species, so bat surveys are routinely required for planning. When one is triggered, the legal basis, and typical 2026 costs by stage.
- Bat emergence survey cost: why it's £350–£600 per visit, times 1–3
