Documents available when an application is made or work is done are used to determine compliance with building regulations. If you want to build a new building in the UK or change an older building, you need to make sure that all work complies with the latest version of the building rules. The first building codes were introduced in the mid-1960s with the aim of making construction work safe, affordable and environmentally friendly throughout Germany. Most of the detailed information on building codes is now available on www.planningportal.gov.uk/buildingregulations/, where the general public can access simplified building codes and professional users have a more organized version of what was on the old DCLG building codes website, including full versions of approved documents and related guidelines available on the DCLG website (now a component) of the website gov.uk). Some types of work require notification to the local authority for building supervision. In England, it is simply work in “zone 1” of a bathroom and new consumer units and complete new circuits. There is more `work to report` in Wales, including wiring in kitchens and gardens. Installers who are members of an approved system of competent persons can carry out such electrical work without having to submit many formal building permit applications, instead, notification is made through their professional organization. For each part, detailed specifications are available free of charge online (in the “approved documents” of the English and Welsh governments) outlining the aspects to be considered. Approved documents are not literally legally binding in terms of how the requirements must be met; rather, they represent the Secretary of State`s expectation of the appropriate minimum standards required to comply with building codes and the common methods and materials used to achieve them. The use of appropriate British and/or European standards is also accepted as a means of complying with the requirements of building regulations. New versions of building codes are generally not retroactive: they apply to any new alteration or alteration to a building (or part of a building), but do not require the renovation of existing elements. There are general requirements for any modification or improvement that the building must not be left less satisfactory in accordance with the work than before the work, and that the treated areas must not be left in a dangerous state in relation to the applicable standards.
The regulations may also, in some cases, stipulate that if sufficient work is being done in an area (e.g. partially new insulation), the rest of this area must be put at an appropriate level; However, the standard required for an existing building may be less stringent than that required for an entirely new building. Part R was introduced in 2016 and will enter into force in early 2017. It requires “network termination points” in buildings to provide high-speed internet access via fiber or copper. These regulations deviated from the usual form because the requirement of the regulations was stated and accompanied by a number of approved supporting documents. If the guidelines of the relevant approved document are followed, it would be proof that you have complied with the regulations. This is the form of building codes used today. The regulation was finally applied to central London from July 1987, completing the uniform nationwide implementation of the building control system. When drivers were asked why they weren`t driving electrically, a British study found that lack of infrastructure was a major concern. In the mid-1980s, the British government introduced the Building Act 1984, which, among other things, introduced a series of approved documents governing functional performance standards and licensing to private inspectors. Changes in the mid-1980s made Britain`s building regulatory system more efficient and accessible.
Documents approved for building regulations are conferred by the Building Act 1984. However, you do not have to adopt the solutions presented in the approved documents. There are indeed other ways to stay compliant. L1 approved documents are specific to apartments, and L2 refers to all buildings except apartments. From time to time, new requirements were introduced and amendments were made to the London Building Act, and a similar development of local laws increased throughout the UK. New interior walls and floors in residential buildings, apartments and living quarters, whether specifically constructed or by physical modification, should achieve a minimum efficiency of Rw 40 dB in laboratory testing. Test data must come from a UKAS accredited laboratory. Combustible materials in the exterior structure of the exterior of tall buildings must comply with building codes, but this guideline has sometimes been interpreted as applying only to insulation and not to siding.

There is concern that fire tests do not accurately reflect real life when a building, cladding and insulation are subject to wear and tear.  The DCLG has set up a weekly electronic newsletter for interested parties.
