Thank you for the opportunity to support your development ambitions.
Arbtech is widely acknowledged to be the leading ecological consultancy in the UK, specialising exclusively in arboriculture and ecology for planning and development sector clients.
Blowing our trumpet; we have been established since 2005 and since then we have been there, done that and got the t-shirts for just about any tree or protected species issue you could possibly face on a site of the proposed development.
To give you confidence in that statement, here are some metrics (as at Q4, 2022):
We now have over 60 team members, and all are directly employed consultants. Known internally as ‘Arbtechers’, they have done literally thousands of surveys over careers spanning in some cases decades, in both the public and private practice sectors. All are well versed in planning policy and wildlife law, as well as having developed good working relationships with the local authorities in their regions.
How do we leverage local relationships and yet offer fixed fees throughout the UK, Crown Dependencies and Ireland? We do this by having approximately half of our staff based at home in strategic locations. So, whether you’re in Sunderland or Southampton, we can cut costs and delays for you at a fixed, all-inclusive price.
If you would like to talk to someone about your development ambitions for your site, please do ask – it’s what we’re here for.
You have been asked to provide a report to your local authority to compliment your planning application because:
At this stage, I would like to save you time and money by recommending the minimum level of survey effort that is designed to satisfy your local planning authority’s ecologist.
As you can appreciate, most structures do not present high-quality habitat for bats, so only a small percentage of sites need anything other than a preliminary bat roost assessment (“PRA”). However, if you have requested a quote for a bat presence/absence survey, it is because your PRA (a physical inspection) has identified triggers for a further survey, such as bats, evidence of bat activity, eDNA evidence, or habitat value.
Therefore, we provide below a quotation for one of our Natural England licenced bat workers to visit you and undertake bat presence/absence surveys, compliant to the Bat Conservation Trust publication on survey standards and protocol ‘Bat Surveys – Good Practice Guidelines’. We have reviewed the available information about your site and are confident that this addresses your immediate needs.
Your bat presence/absence survey comprises several visits to your site between dusk and dawn, when bats are most active, for surveyors to use remote detection devices, which may include infra-red image capture and bat detection devices, and to physically observe any bats emerging from or re-entering features/apertures (there may be no emergences) that may be suitable for roosting.
Your local planning authority will expect us to be able to observe all elevations of your building simultaneously unless your PRA confirms that the roost is confined to one particular area. Consequently, several surveyors may need to be present on your site, with larger, more complex shaped buildings generally requiring a greater survey effort than e.g. a standard detached family home.
Finally, if you haven’t done so already (normally forms part of the preliminary roost assessment), our consultant will perform a desk study of local ecological receptors within 2km of your site (if any) and incorporate the results into your report.
There are then 2 possible outcomes, as follows:
|What we found at your site||What this means for you|
|You do not have bats being observed and|
recorded emerging from or re-entering your property.
|Your planning permission can be progressed without delay.|
|You have bats. Bats were observed and recorded emerging from or re-entering your property.||Your local authority may require you to submit a mitigation method statement as a condition of consent.|
You will also need a European protected species licence.
Yes. (If you haven’t already obtained it for your PRA).
Your local planning authority will expect to see biological records incorporated into the desk study element of your report. Without this valuable information, they will simply reject your report out of hand, because the methodology will not meet the minimum standard of survey defined by the Chartered Institute of Ecology and Environmental Management.
*Biological records are a data set that you or we must procure from your local provider; often your local authority themselves, or a wildlife trust.

Bat presence/absence surveys comprise multiple visits in the vast majority of cases, and it is worth noting that for scientific rigour these visits should be spaced at least 3 weeks apart (your local authority is unlikely to accept anything less). Finally, unless agreed otherwise, your report will normally follow within one week. Timescales for delivery of third party data or services may vary.
We need to access all the internal and external areas of your site, including any buildings, compounds and other structures, including loft spaces and any other voids. We will also need to make some ground-level assessments of any trees that may be impacted by your development proposals (if any).

All our costs are inclusive of our time, travelling expenses and your report.
It is worth bearing in mind that British bats hibernate throughout the winter months when the insects on which they predate are less prevalent. To reduce the risk of a type II error (false-negative survey result), your local planning authority will expect to see that your bat presence/absence survey has been conducted between May and September.
Depending on your location, the climate, type of survey, and the sensitivity of the suspected roost, there may be an opportunity to relax these seasonal restrictions slightly (or they may need to be tightened up). We will confirm this to you at the time of your instruction.
Bat presence/absence surveys comprise multiple visits in the vast majority of cases, and it is worth noting that for scientific rigour these visits should be spaced at least 3 weeks apart (your local authority will not accept any less).
Finally, surveys should be undertaken on nights were the minimum temperature is not less than 10°C; there is no heavy rain; and where wind speeds are not too high.
We are widely respected for our commitment to science, a strength that is leveraged to your benefit when your local authority’s planning officers assess our report. Therefore, at Arbtech, we work to the nationally accepted guidelines and standards by default.
However, we understand that there are many other pressures on any given project and therefore in some circumstances, it may be appropriate to discuss undertaking your survey in a more condensed timeframe than we have outlined above, assessed on a case-by-case basis by our Principal Ecologist and Bat Licence Lead – Natalie Evans.
In these instances, the client must accept that there is a risk that the survey could be regarded as sub-optimal by your local planning authority and/or the regulator, and that this may result in delays, refusal of consent, or their insistence upon a further survey effort in the following season.
At Artech, we firmly believe that guidelines are just exactly that: guidelines. We employ free-thinking scientists who are not slaves to these guidelines. Each situation is judged on the strength of its own merits and our consultants will attempt to help clients build a supporting case for sub-optimal surveys where there are other relevant factors that need to be considered.
As soon as we have your booking information, you will receive an automated booking confirmation e-mail, followed by direct contact from one of our friendly ‘Arbtechers’ same or next working day, to arrange a mutually agreeable site appointment. This person will be your Project Manager and will be your primary point of contact for the duration of our engagement.
We hope that our Fixed Fee is met with your approval and look forward to working with you very soon.
