“After an extensive design review, it became clear that achieving a 10% biodiversity gain onsite at our Harold’s Wood site near Romford wasn't feasible. We've therefore partnered with Nattergal to provide the necessary additional gains.

I’m delighted that we have been able to start our BNG delivery journey together with Nattergal. It’s been inspiring to see the diligence and integrity with which they approach their work.

In fact, our collaboration extends beyond BNG. They will also create a new habitat for a population of slow worms currently residing at Harold’s Wood, ensuring their safe relocation to facilitate development.”
