CUTTING EDGE CIVIL & ENVIRONMENTAL ENGINEERING
By continually monitoring new techniques and technologies, and staying fully conversant with current legislation, we provide cost-effective solutions while working closely with each client to find the most workable approach for their project.
We work with a wide range of clients, including self-builders, property developers, housebuilders, architects, planning consultants, local authorities, the Environment Agency and water authorities. We support projects across the commercial, residential, retail, leisure, educational and mixed-use sectors.
We cover all aspects of civil engineering design, nationwide, including:
- External Works Design
- Below Ground Drainage Design
- Sustainable Drainage Systems (SuDS) Design
- Flood Risk Assessment reports (FRAs)
- Flood Warning and Evacuation Plans (FWEPs)
- Surface water management schemes, including SuDS reports
We can also provide combined Flood Risk Assessment and SuDS reports, as well as combined Flood Risk Assessment and drainage strategy reports, giving you everything you need to support your planning application in a single, coordinated submission.
Our Core Values
At Nimbus Engineering, we are committed to delivering practical, innovative, and cost-effective solutions that support planning approvals and promote sustainable development. Our approach combines technical excellence, meticulous attention to detail, and a client-focused ethos to ensure every project progresses efficiently from conception to completion.
As over 90% of our commissions arise through word of mouth, integrity and the cultivation of long-standing client relationships are fundamental to our practice. We pride ourselves on providing clear, honest advice, and if we believe that a site is unlikely to achieve planning approval due to Flood Risk, SuDS, or Drainage Design Constraints, we will advise you accordingly before proceeding.

FLOOD RISK ASSESSMENT & SUDS REPORTS
We provide professional SuDS reports and Flood Risk Assessments (FRAs) designed to support planning applications and the discharge of planning conditions across the UK. Our services also include drainage strategy reports, detailed drainage design and SuDS design, all supported by the technical documentation needed to meet local authority standards.
Our reports can be delivered as standalone documents, or combined into a comprehensive Flood Risk Assessment and SuDS report (FRA and SuDS report), or a Flood Risk Assessment and drainage strategy report, depending on the requirements of the relevant Local Planning Authority (LPA) and Lead Local Flood Authority (LLFA).
Operating nationwide, we work closely with planning authorities throughout the UK and understand their often-varying SuDS and drainage requirements. We liaise directly with LPAs and LLFAs to ensure our reports not only achieve planning approval, but also provide practical, cost-effective drainage solutions that are fully suitable for construction.
We recognise that project budgets are increasingly constrained. That’s why we focus on delivering cost-effective SuDS reports without compromising on quality or compliance. Our team remains readily available throughout the process to provide expert advice and support, ensuring a smooth, efficient route to planning approval.

Customer Reviews
“I have really enjoyed working with Nimbus. Sadia is extremely knowledgeable and is always willing to go out to her way to help clients. The speed at which Nimbus produce their work is impressive and the prices are extremely competitive. Special mention to Ryan Herity after we worked closely together on a couple of schemes. Always happy to pick up the phone andanswer questions. He provided solutions that led to drainage officer approvals – you can’t ask any more than that!”

I would wholeheartedly recommend Nimbus for any and all SuDS advice. Nimbus shoot from the hip, and make my life easy, knowing if I have engaged them, I do not have to ever worry.”
