Individual Property Resilience (IPR) helps property owners prepare for flooding by using tailored solutions to reduce damage and speed up recovery. It works by keeping water out and making buildings more resilient when floods do occur.

Why IPR Matters

The approach identifies measures that are bespoke to the property requirements in anticipation of flood events, enabling those at risk to speed up recovery and reoccupation post-event.

Property Flood Resilience (PFR) measures aim to reduce the amount of water entering buildings through resistance measures, limiting the damage caused by water through resilience and adaptation to properties. Measures include:
Barriers

Fitted to property openings such as doors & windows to seal from floodwater entry.

Automatic flood safety doors

These can be closed and locked in anticipation of flooding.

Non-return valves (NRVs)

Fitted to drains around the property to prevent floodwater or sewage back-up.

Airbricks/ Airbrick Covers / Pumps

Creating a seal against floodwater. Managing floodwater levels for properties at risk of groundwater flooding.

The Code of Practice

The Code of Practice sets out recognised standards for Property Flood Resilience (PFR), guiding the installation of protective measures for buildings at risk of flooding. It applies both to properties that have already experienced flood events and those seeking proactive resilience.

Aligned with CIRIA C790B and BS 851188 guidance, it ensures solutions are practical, cost‑effective, and compliant with regulatory expectations, helping owners and organisations strengthen long‑term flood protection. These measures include:
IPR
Hazard Assessment

Identifying flood hazards and quantifying potential impacts to understand the level of risk.

Property Survey

Detailed inspection of the building to assess vulnerabilities and resilience opportunities.

Options Development

Evaluating and selecting suitable PFR measures tailored to the property’s needs.

Construction

Implementing chosen resilience measures with quality assurance and compliance to standards.

Commissioning & Handover

Testing installed measures, ensuring functionality, and providing clear guidance to users.

Operation & Maintenance

Supporting long‑term resilience through ongoing upkeep, monitoring, and periodic reviews.

Our industries

Waterco Datrys

Industries we support

We deliver practical flood risk solutions backed by deep knowledge of the Code of Practice (CoP) for Property Flood Resilience (PFR).

We carry out full flood hazard assessments using advanced modelling tools like MIKE FLOOD, Flood Modeller Pro (formerly ISIS), TUFLOW, and HEC-RAS to quantify risk.

This data informs drainage strategies, detailed designs, and tailored PFR recommendations that meet regulatory standards and improve resilience. We support individuals across the industry who work to minimise the risk of flooding such as:
Property owners, occupiers and managers (residential and non-residential)
Manufacturers and suppliers of PFR measures
Construction contractors and installation companies
Sewerage companies

Lead Local Flood Authorities

Lead Local Flood Authorities (LLFAs) play a vital role in managing local flood risk, helping communities reduce vulnerability and recover more effectively after flood events.

We support LLFAs with specialist advice and technical services that strengthen resilience, improve planning, and enhance quality of life for those affected by flooding. Our expertise ensures strategies are practical, evidence‑based, and aligned with regulatory expectations with services including:

Frequently Asked Questions

A Flood Risk Assessment checks if a site is suitable for development by evaluating its risk of flooding. Requirements vary by region, but usually depend on the site’s location, size, and type of development. In England and Scotland, it’s called a Flood Risk Assessment; in Wales, it’s a Flood Consequence Assessment.

A Flood Risk Assessment is typically required when any of the following applies:

1. The site is over 1ha.

2. Can be classed as a major development.

3. Located in Flood Zone 2 or 3.

4. Drainage area is classed as critical.

A Drainage Strategy (SuDS report) is needed if your site is over 1ha, a major development (10+ units), in Flood Zone 2 or 3, in a critical drainage area, or if building a new structure.

Local planning authorities may request one to ensure your project complies with regulations and avoids future issues. Checking early helps prevent delays, and our team can guide you through the process.

In certain areas the LLFA, EA, SEPA or NRW may not hold sufficient information for your site to inform their decision on flood risk, flood sources and flood hazards. We can support your Flood Risk Assessment in-house with hydrology assessments and detailed hydraulic modelling.

Hydraulic modelling simulates how water behaves under changing conditions to assess flood risks. Using software such as MIKE FLOOD, Flood Modeller Pro, TUFLOW, and HEC-RAS, we predict flood depths, velocities, inundation rates, and hazard ratings. These insights inform UK flood maps and help clients develop effective flood management strategies.
