Ecologist support this summer: unit prices without the legwork

If you’re advising clients on biodiversity net gain, you complete the DEFRA metric, establish how many BNG units the development needs, then figure out the cost of buying them off-site.

That last step is where most people get stuck - there’s a faster way through it.

If you're working on a project that needs BNG off-site, your client will want a cost number - and getting that number credibly, quickly, without spending hours on research, isn't always easy.

That’s where our BNG Price Calculator comes in.

Built on the latest market data from our nationwide network of 175+ suppliers, it gives you an immediate, credible price range for off-site BNG units — by habitat type and location. It’s free to use, takes seconds, and gives you something concrete to put in front of your client.

Try it at bngpricecalculator.com.

Want more than a number?

Sometimes you are on-site with little internet access, or a price range isn’t enough.

Our Ecologist Summer Support offer is there for exactly that.

Send us your DEFRA Metric and our Account Director Sam Allen will return in a few hours with a range of credible costs - and ready to answer any questions you have.

That means:

• You look commercially sharp in front of your client

• You have a real number to work with, not a guess

• You have a named contact at Biodiversity Units UK for any follow-up questions

• And we'll plant a tree for every opportunity you bring our way

Just contact sam@biodiversityunits.com

Why choose us?

BNG unit transactions are what we do - and the scale at which we operate means we have better sight of real market pricing than almost anyone else.

In 2025, BDU facilitated 11% of all BNG unit transactions in England. We account for 18% of allocations on the Natural England register, and we work with over 85% of BNG suppliers across the country.

We work with Ecologists all over the country to help them create BNG solutions for their clients. We have even built an Ecologists Directory to promote the sector. Indeed we've just updated it with 13 new companies, so developers and landowners can find the right expertise faster.

Our Quarterly BNG Pricing Report was the first report in the industry - back in 2024 - which gave transparency to the nationwide pricing of this emerging market.
