The Amendment Regulations amend the Building Regulations 2010. The Amendment Regulations introduce a new Part R in Schedule 1 to the Building Regulations (physical infrastructure for high-speed electronic communications networks).

New Part R (in-building physical infrastructure for high-speed electronic communications networks) in Schedule 1 to the Building Regulations 2010
Building control bodies will wish to note the following:
•Part R transposes the requirements of Directive 2014/61/EU into English law. The guiding principle of Directive 2014/61/EU is to contribute to a reduction of the future costs and obstacles to deploy superfast broadband. It should be noted that a standard copper telephone cable, when connected to a service provider’s fibre network, can currently deliver superfast broadband speeds of up to 70 Mbps.
•Part R requires that all new buildings are adequately equipped with the necessary infrastructure to support a connection to superfast broadband rather than provide the connection itself.
•The requirement only considers internal physical infrastructure required for the building, and not any infrastructure that may be placed within the site curtilage or boundary, as this is outside of the scope of the Directive. Any site-wide infrastructure that may be required should be installed by the developer in consultation with their preferred telecoms provider.
•Regarding major renovation works, Part R requirements only apply where the existing in-building physical infrastructure is being renovated, either wholly or across a significant part. The Part R requirement will therefore only apply to change of use projects and extensions where building work (i.e. work requiring a building regulations application) encompasses modifications to a significant part of the existing in-building physical infrastructure.
•We have provided for exemptions to the requirements, including an exemption for major renovation works if the cost of compliance with Requirement R1 would be disproportionate to the benefit gained. It is anticipated that there would be very few instances where this exemption would be acceptable. Building Control Bodies should make a case by case assessment as to whether costs in meeting the requirement are disproportionate to the benefits of enabling superfast access to broadband.
