Daytime Bat Surveys

EMEC Ecology undertakes bat surveys throughout England including all the counties in the East Midlands. Projects range from bat surveys of proposed barn conversions up to large scale development schemes. Recent projects requiring bat surveys have been undertaken within Nottinghamshire, Leicestershire, Derbyshire, Lincolnshire and Staffordshire.

EMEC Ecology carries out bat surveys as part of large public and private sector projects, or small residential development sites including re-roofing and home extension projects. Each bat survey will therefore be specific to a site and the costs will vary accordingly. EMEC Ecology will be happy to provide a quotation for a bat survey that will be both efficient and cost effective to the site specifics.

If you require a quotation for a bat survey please send an email to us at including any site plans that you have available (or details and photographs of the site if applicable) with details of the proposed development plans of the site, along with your name and contact details. Should you wish to contact us at the office please call 0115 964 4828.

Details are provided below on what a bat survey can involve. This information is also available as a Bat Survey - Information Sheet PDf document.

There are currently 18 resident species of bat in the UK. All bat species receive protection under UK and European legislation, including the Wildlife and Countryside Act 1981 (as amended), the Countryside and Rights of Way Act 2000 and the Conservation of Habitats and Species Regulations 2010 (as amended). Together, this legislation makes it illegal to; intentionally or deliberately take, kill or injure a bat; damage, destroy or obstruct access to bat roosts; deliberately disturb bats.

A bat roost is defined in the legislation as "any structure or place which a bat uses for shelter or protection". Roosts are protected whether or not bats are present at the time. If a development activity is likely to result in the disturbance or killing of a bat, damage to its habitat or any of the other activities listed above, then a licence will usually be required from Natural England.

Survey Methodology

Bat surveys begin with an initial site assessment, which involves a daytime bat survey of the building(s) / tree(s) to be affected. The bat survey involves looking for signs of bats such as droppings, feeding remains, scratch marks, urine stains, and actual sightings, as well as potential access points and roost sites such as holes, cracks and crevices.

Should evidence of bats be found or areas suited to roosting bats identified it may be necessary to complete further evening emergence and / or dawn swarming surveys. These bat activity surveys allow for identification of roost entrance / exit points, number of bats present and species of bat using a roost. See our Bat Activity Surveys page for more details.

Although the initial daytime assessment can be completed at any time of year, evening and dawn surveys are constrained by the main bat activity season which runs from May to September inclusive. During the winter months bat activity is reduced and during long periods of cold weather bats hibernate and so bat activity surveys at this time of year are ineffective. The best time to complete evening surveys is during the period May- late July / August whilst bats congregate in large maternity colonies.

Applying for an EPS Licence

When bat roosts are recorded, it is usually necessary to apply for a European Protected Species (EPS) licence for works to progress. Should an EPS licence be required, EMEC Ecology can apply for this on your behalf. The EPS licence application requires the production of a method statement, completion of an EPS application form and the completion of a reasoned statement in support of the application. The method statement will require site specific mitigation. For development sites where there are challenging situations, EMEC Ecology has experienced staff in finding the appropriate solutions.

EMEC Ecology is also able to undertake Natural England's Low Impact Bat Licence applications when applicable.
