Sustainable Drainage Systems (SuDS) are no longer optional — they're a planning requirement for many new developments across the UK. But the rules aren't always straightforward. Local authorities interpret guidance differently, and expectations can vary depending on site size, flood zone, and location. In this [...]

Flooding can happen suddenly and can cause significant damage to property, disrupt daily life, and pose serious safety risks. Having a household flood plan in place will help you and your family stay safe, minimise property damage, and recover quickly after a flood event. Hopefully [...]

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. But many applicants fall into the same traps, leading to unnecessary delays or even outright rejections from the planning [...]

Introduction One of the most common reasons for delays or rejections in planning applications is the failure to demonstrate adequate surface water management. A well-prepared SuDS (Sustainable Drainage Systems) report can be the difference between a swift approval and months of costly setbacks. At Nimbus [...]

This is a question we’re frequently asked by developers — so rather than explain it again and again, we’ve created this article to help clarify the importance of BRE365 percolation testing and how it relates to your SuDS (Sustainable Drainage Systems) report. Why Are SuDS Reports Required? A SuDS [...]

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. In some cases, you may also be asked to [...]

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 [...]

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, [...]

Introduction As experienced engineers, we understand the critical role that accurate survey information plays in the success of any drainage design project. Incomplete or incorrect data can lead to costly delays and complications, impacting both budgets and timelines. This understanding prompted us to begin conducting BRE365 [...]

SuDS Report: Why You Need One for Your Development Project One of the most common questions we receive is: "I’m replacing an existing building with a similar-sized one—why do I still need a SuDS report?" If you're applying for planning permission, you’ve likely encountered several required surveys [...]
