Introduction Sustainable Drainage Systems (SuDS) are a critical part of planning applications — especially for developments in flood-sensitive areas or where impermeable surfaces are being added.

Many applicants don’t realise that a SuDS report is a mandatory requirement for planning validation—until it’s too late. You’ve prepared your documents, you're ready to hit "submit", and then you’re told a Sustainable Drainage Systems (SuDS) report is still needed.

Imagine a sustainable, forward-thinking solution that reduces flooding while providing additional benefits. That’s precisely what the combination of green roofs and Sustainable Drainage Systems (SuDS) offers. The Urban Flooding Challenge Modern cities are filled with impermeable surfaces like roads, roofs, and pavements, preventing rainwater from naturally soaking into the ground.  The result? Excessive surface runoff and the overwhelming of existing drainage systems—especially during

This is a common question we receive from developers and clients when providing below-ground drainage designs. We understand—construction is expensive, and unexpected costs add up quickly. However, even if your local council has not imposed a planning condition for a Sustainable Drainage System (SuDS) report, it is still a requirement under building regulations and water
