OFF-SITE housing manufacturers are set to trial a performance guarantee for prefabricated homes.
Developed by BRE Certification the Loss Prevention Standard for Innovative Dwellings 2020 will assess the performance and design of modern methods of construction including lightweight steel frame buildings and timber frame kits.
Currently manufacturers have to go through individual approval regimes with regulators and warranty providers, making comparisons between each application difficult for mortgage lenders and insurers.
The standard will provide a consistent method for assessing building systems that have not been extensively used in the UK.
It is due to be launched later this year and will help mortgage lenders assess a home's quality.
BRE Certification's Paul Sims said: 'Calibration trials can now begin.This stage will help us refine the standard.'
