Part L of the Building Regulations has been amended in 2013 and includes new versions of L1A, L2A, Domestic & Non-Domestic Building Services Compliance Guides and some changes to Approved Document L1B and L2B; these changes however, will come into effect starting with 6 April 2014.

For a complete list of changes, please see the official – free to download – documents on the Planning Portal.

The housing standards review of the Building Regulations – the note supporting the ministerial statement – can be accessed on the official Gov.uk website (PDF). You can also see the published policies from 14 March 2014.

The amened Building Regulations tackle the following:

  • Access (an optional level of accessibility will be introduced in Part M which will set out  criteria for age friendly, accessible and adaptable housing.)
  • Security (recognised value of a single minimum security standard for new homes, based on industry’s best practice)
  • Water [a new, tighter level of water efficiency into the Building Regulations, to be set at 110 litres/person/day (lpd)]
  • Energy [a “Building Regulations only” approach, with no optional additional local standards in excess of the provisions set out in Part L of the Regulations; strengthening of the energy performance requirements (incorporating carbon
    compliance, energy efficient fabric and services), and the delivery of allowable solutions]
  • Space ( a new national standard – not a Building Regulation – which will offer a consistent set of requirements with regard to the internal area of new homes).
