Do you need a Bat Survey for a planning application in London in 2021?
Bat Survey London: London is densely populated and despite the pandemic of the last year or so, with the resulting increase in home working, there’s no signs of the growth of the capital slowing down in either economic prosperity, home and property values, and population.
For example, the population of London is only 12.5% of the UK as a whole, but the city generates almost a quarter of total GDP. Likewise, in 2020 the average price of a home in the capital rose above the £600,000 mark for the first time in history. Finally, the present population of greater London is over 9 million people. By 2050 that is predicted to grow by another 2 million.
What this means, is that what is already a hive of development activity is likely to get even busier. Pressure will mount on the 32 boroughs of London to consent to more and more development, and as high streets feel the double hammer of the lockdown and a mass move to online shopping, perhaps our town and city centres will become even more densely populated as large stores and offices that used to be able to command enormous rents slowly, one by one, get converted into dwellings for the extra 70,000 people annually that will come to call London their home.
Clearly, there is a trade off with biodiversity anytime outside spaces (natural habitats) and existing, imperfect structures (with architectural defects and features that provide for suitable bat roosting habitat) are sacrificed for re development. In short, all of this new construction, conversion and renovation activity risks a loss of bat roosting habitat on a wholesale scale.
However, with the Mayor of London committing heavily to e.g. tree planting, and improvements to green infrastructure and opens spaces, there will be yet more pressure to ensure that consented development activity (to say nothing of permitted development) is protective or even additive to local biodiversity.
This is compounded by the various borough’s commitments in their own biodiversity action plans. And, of course, these relatively local considerations are given teeth the forthcoming Environment Bill enshrining in law the mandatory biodiversity net gain of 10% across the board.
Then of course there are volunteer interest groups that have some influence over planning applications, and even policy. London Bat Group for example sells local biological records search data to consultants (like Arbtech) to integrate into London bat surveys and preliminary roost assessment reports, to inform decisions about proximate habitat use and quality using known sightings of various bat species and roosts as a proxy.
The more data these organisations collect over time, the better the resolution of the spread of bats and their roosts throughout London is. This of course means that with each passing year, bat surveys are more likely to lead to resistance to development and or licenced mitigation for habitat loss.
So, massive pressure to develop, convert and restore… coming up against massive pressure to avoid, mitigate and even enhance existing habitats. What’s the answer?
Bats and Planning Permission in London
Well, it certainly isn’t to ignore the issue. Bellway Homes was criminally prosecuted and fined £600k in January 2021 for the destruction of a bat roost on a site in Greenwich. And they already had a planning consent. If you’re not even at that stage yet, then the rest of this article contains vital information if you have been asked by your LPA to get a bat survey in London.
London’s #1 Bat Surveyors – Hundreds of reviews can’t be wrong!
Of course, all eight species of 17 that breed in the UK are legally protected, as are their roosts from disturbance and destruction (roost), harm and killing (animals). This doesn’t mean that bats can or should stop you from achieving your development ambitions; it just means that there’s a protocol to follow.
Here’s what that looks like.
Step one is to get a baseline report done. This takes the form of a preliminary roost assessment (often called a phase one or scoping bat survey). This is a physical survey and desk study exercise.
The desk study looks at the proximate landscape and habitat connectivity, as well as taking in data from DEFRA and Natural England, and London Bat Group.
The goal is to critically assess the impact on a potential roost’s destruction, in terms of how it would disperse local bat populations within the subject site to the wider setting, as well as historic (licenced) roost destructions that maybe in turn, dispersed their own bat population to within the subject site.
In truth, this rarely (but certainly not never) turns up surprise information that might significantly affect the sensitivity of what you’re planning to do.
The physical survey is very simple, too. There’s an assessment of three criteria that could trigger bat emergence surveys (often called ‘nocturnal’ or ‘dusk and dawn’ surveys) or allow your planning application to progress unhindered.
In the majority of cases, bat emergences surveys are not recommended. The physical element of your initial bat survey seeks to assess the following: bats; physical evidence of bat activity; and features on the exterior of the buildings that could be habitat, or very actually are habitat.

What a bat survey in London costs, and why choose Arbtech?
A PRA bat survey in London will cost you from £389+VAT. That’s a generalisation. We have done bat surveys on the houses of Parliament. Big building.
It was a lot more than four hundred pounds. Equally, sometimes we do multiple surveys for architects and planning agents in and around London – sometimes we can visit several properties in a day and that reduces the per unit cost significantly.
If you fill out the box at the top of this screen, we’ll get in touch same day and have a one-page fees sheet over to you. A signature is all we need (which you can scan or take a photo on your phone), and we’ll jump right on it. Rapid and hassle-free is our mantra here at Arbtech.
In terms of how we deliver our work, we’ve tried to build company that we’d actually like to do business with. Arbtech’s bat ecologists take complete ownership of your ecological site issues until they are resolved to the fullest standard. Our USPs are:
Speed: Instant quotes, rapid surveys, reports in days not weeks.
The Arbtech Guarantee: Follow our advice, and we guarantee that you get planning—or your money back.
It’s also a worth brief mention that the primary reason we can offer fixed, all-inclusive fees with no hidden extras (mileage, etc) whether you’re in Exeter or Edinburgh is because we have around 30 staff; a HQ in Chester where the administrative machine is, and then 20 or so consultants in strategic locations around the UK. Our team are not subcontractors.
They are all full-time, direct employees and have lived and worked local to you for their entire careers. This allows us to leverage the benefit of local knowledge of the various London boroughs and hoe they assess applications, as well as the fact our works and consultants are known quantities to the people who will be looking at your planning application.
