Property flood resilience
In April 2017, CIWEM, ICE and RICS joined forces to call for a code of practice for the installation of property-level flood resilience measures to help householders and insurers avoid repeat flooding.
Currently, incomplete information about the type and quality of property flood resilience (PFR) increases the vulnerability of householders and insurers to flooding through poor quality PFR installations. Two building contractors alerted the Chartered Institution of Water and Environmental Management (CIWEM) to the existence of poor quality PRF installations. Simultaneous research by the Building Research Establishment (BRE) supported this view.
As a result, a coalition of leading civil engineers, water and environment management professionals and chartered surveyors are calling on the government to adopt a code of practice for the installation of PRF measures – or leave thousands of properties vulnerable to repeated flooding, wasting millions of pounds of taxpayers' and insurers' money.
Since the winter storms of 2015, when over 16,000 homes suffered flooding, properties flooded at that time have been able to apply for up to £5,000 of PFR funding. This comes from central government but is administered by local authorities. However, many PFR installations have been poor quality.
While DEFRA's Flood Resilience Action Plan (September 2016) calls for 'standards, training and skills', this newly-formed coalition want to go further. This week the coalition announced the creation of a steering group to oversee the Construction Industry Research and Information Association's (CIRIA) development of the PFR code of practice.
 Clear unambiguous installation instructions
A code of practice would have three core advantages. First, it would provide clear unambiguous descriptions about what to do when installing PFR at each property, for contractors, engineers and surveyors on the one hand, and householders on the other.
A PFR code of practice would enable all stages in PFR installation, from assessment of the most appropriate type of PFR at the start of the process, to the creation of an insurance certificate about the PFR installed in a property at the end, to be performed to suitably high standards.
The code of practice needs to be not just a general guide but a chapter by chapter description of what contractors, engineers and surveyors need to do and an easily-understood description of what members of the public need to look for in terms of training, skill and insurances from PFR installers. The guide will be available for free on the internet when finished.
 Effective coalition of leading built environment organisations
The second advantage of the proposed code of practice comes from the breadth and high standing of the built-environment coalition– CIWEM, ICE, and RICS – who collectively have the most direct responsibility for property flood protection.
By including civil engineering, water and environment managers and chartered surveyors in one group, the code of practice will have good standing in the built environment sector, can be rolled-out most effectively and include the unique needs of each professional group where appropriate.
 Reliable and detailed risk information for insurers
This will enable the insurance industry to assign market-based insurance costs to individual properties based on each property's flood risk and types of installed PRF, rather than being based on average estimations by flood-risk area. This will help align the incentives between property owners, contractors, engineers, surveyors, insurers and funders so that the most effective PFR measures are installed.
At present, it is impossible for insurers to estimate reasonable market costs for insuring each property. A code of practice and certification scheme would help develop market intelligence for the insurance industry, both for present needs and future needs after 2037, when the current insurance regime for at-risk properties (FloodRe) will end.
 The benefits of a new built environment collaboration
Awareness of this issue, the seriousness with which the coalition is responding, and the proposed way forward, are all a testament to the strong relationships between contractors, engineering and surveying professionals.
Cross-professional working alerted us to the existence of the issue and will help us solve it. Working collaboratively with built environment professionals throughout the whole process of PFR installation will enable the coalition to oversee the development of a code of practice to help professionals, householders and the insurance industry deal with flood risks most effectively.
