Unda can save you time and money

Using Unda can help reduce time and costs because of our excellent relationship with both local planning authorities and the Environment Agency and similar bodies. However, for many of our clients it is the simple fact that a high quality FRA can make an enormous difference to the success or failure of their planning application that makes the service so popular.

Experience and Environmental Legislation

Unda’s team of flood risk consultants have gained experience across a range of developments, from single storey extensions to large multiple dwelling housing schemes and change of use of buildings from commercial to residential. Our reports are designed to answer the questions raised within current legislation (NPPF in England, PPS25 in Scotland and TAN15 in Wales). Our reports can cover pre-feasibility and initiation right through to planning consent and discharge of planning conditions relating to potential flooding issues.

Our consultants can provide invaluable advice and guidance on flood risk at every stage of the planning process and have developed an excellent working relationship with the statutory agencies (the Environment Agency, Natural Resources Wales and the Scottish Environmental Protection Agency).

We work across all scales of planning from a minor extension or change of use through to large scale and major residential, commercial and industrial developments. We also have considerable experience working with renewable energy schemes, particularly Solar Farms, Biogas / Anaerobic Digestion Plants and Wind Farms / Turbines.

Why do I need a Flood Risk Assessment for Planning? – NPPF, PPS25, TAN15?

   In England

Under the National Planning Policy Framework (NPPF), you need to complete a FRA if:

  • The development site falls within the Environment Agency (EA) Flood Zone 3 (High Risk) or Flood Zone 2 (Medium Risk) of areas at risk of flooding from rivers or the sea;
  • The site has been classified by the EA or Local Planning Authority (LPA) as having critical drainage problems, or being within a critical drainage area;
  • The site is over 1 hectare (10,000m2) in area.


   In Wales

Under TAN15 (Technical Advice Note 15) a FCA (Flood Consequence Assessment) is required if you are within Zone C1 or C2 or Zone B if flooding has been identified as a material consideration.

   In Scotland

Under the Scottish Planning Policy (SPP) a FRA will be required to development in the medium to high category of flood risk, or in the low to medium category where factors indicate heightened risk or where essential infrastructure and the most vulnerable uses are proposed.

A FRA is required to assess the risk of flooding at the present day and for the lifetime of the development (including an allowance for potential climate change). It must demonstrate that the development will not increase potential flood risk, and will manage any flood risk on site safely to ensure the safety of site users and occupants.

Our expertise in FRA’s for all planning legislation can help you to find a cost effective way to meet the flood risk planning requirements.

Code For Sustainable Homes, BRE Environmental Assessment Method and Ecohomes:

Environmental codes and assessments aim to protect the environment by ensuring development is sustainable. Development is encouraged in low flood risk areas, or measures are required to reduce the impact of flooding. Flood risk is a material consideration of sustainability and a FRA is required as part of BREEAM (BRE Environmental Assessment Method)Ecohomes or the Code for Sustainable Homes (CfSH).
A FRA can be required as a mandatory component or to achieve additional credits as part of BREEAM or the CfSH even where it is not required under the core planning legislation (NPPF, TAN15 or SPP).
