Bat surveys in Cardiff
If your planning application in Cardiff changes a roof, a loft, an older building or a mature tree, Cardiff Council may ask for a bat survey before it decides. We can introduce you to one vetted, licensed bat ecologist who covers your site in Cardiff.
Beatrice Vasey is not a bat ecologist. We introduce you to one vetted, licensed ecologist and are paid a referral fee by that business.

Where bats feed and travel around Cardiff
Bats follow dark, sheltered routes such as rivers, canals, hedgerows and tree lines to feed and move between roosts. In Cardiff, the River Taff, the River Ely and Bute Park are the kind of places bats feed and travel through, so older buildings and mature trees nearby are more likely to need follow-up surveys after a preliminary roost assessment.
Survey types, seasons and costs
Most projects in Cardiff start with a preliminary roost assessment. On larger or greenfield sites, bats are usually covered first by a preliminary ecological appraisal, which checks for other protected species too. Emergence surveys only run from May to September, so book the assessment early in the year to keep any follow-up surveys inside one season.
| Survey | When it can be done | Typical cost |
|---|---|---|
| Preliminary roost assessment (PRA) | Any time of year | £400 to £600 |
| Emergence surveys | May to September | £800 to £1,000 per survey |
| Bat activity surveys | April to October | Quoted per site |
| Hibernation surveys | November to March | Quoted per site |
