Frequently asked questions about our SuDS Report service.​

  • Why invest in a SuDS report?
    Investing in a SuDS (Sustainable Drainage Systems) report is crucial for anyone planning a new development, extension or alteration to a property. The SuDS report assesses the site’s drainage characteristics and recommends sustainable drainage systems to manage surface water runoff. ​ Our expert analysis of drainage characteristics and recommendations for sustainable drainage systems ensure compliance, sustainability, and flood risk mitigation
  • Why do I need a SuDS report?
    The incorporation of Sustainable Drainage Systems (SuDS) is a requirement for all new developments, and the level of detail required in a SuDS report can vary depending on the application type and the Lead Local Flood Authority’s (LLFA) requirements. LLFAs are increasingly requesting SuDS reports for even the smallest of project due to the increasing risk of flooding and the effects of climate change. Major developments and those in critical drainage areas or high flood risk zones should flood risk assessments and surface water drainage strategies carried out prior to submission. The local planning authority and LLFA have the final say on whether a SuDS report is required, so it is best to speak to them before submitting a planning application. Sometimes, a more in-depth report, such as included detailed construction design, may be requested either at the planning application stage or to discharge a planning condition. SuDS Designs provide guidance throughout the planning process from start to construction, including assistance with determining flood zone locations and offering design to confirm feasibility and calculate the mitigation against pollution your project can offer.
  • How can SuDS help improve my relationship with the environment?
    A SuDS Report can improve your relationship with the environment by ensuring that surface water runoff from your development is managed in a sustainable and environmentally responsible manner. Traditional drainage systems can cause flooding, pollution, and erosion, which can harm the natural environment. SuDS seek to mimic natural drainage systems and use a range of techniques to reduce the impact of surface water runoff on the environment. By investing in a SuDS Report, you can show that you are committed to reducing your development’s impact on the environment, while providing cost effective solutions.
  • Who are the intended recipients of SuDS reports?
    Entities engaged in residential construction and development projects Specialists in real estate, such as architects, urban planners, and real estate agents Homeowners and personal property investors Corporate entities across different industries Insurance underwriters and financial lending institutions
  • Is a SuDs report adequate for meeting the requirements of the Local Planning Office or LLFA?
    SuDS reports aid with planning applications, either in the pre-planning stage or to meet specific conditions before planning consent. They initially examine infiltration SuDS, the preferred surface water management method. The feasibility of such techniques impacts the potential of other SuDS approaches. The level of detail varies as per the specific demands of your local council – we can help advise what you’ll need from the SuDS report to meet the requirements.
