The Code for Sustainable Homes was withdrawn and no other local technical standards or requirements are permitted. However, the new national technical standards are optional and should only be required through Local Plan policies if they address clearly evidenced need. Their impact on viability also needs to be considered. South and Vale Councils have an opportunity to take forward these standards into Local Plan policy. The new approach to technical standards was launched in March 2015 under the ‘housing standards review package’ and gives local authorities the option to set technical standards exceeding the minimum required by building regulations in respect of accessibility.
