Building Regulations Part L Changes

March 10, 2014 9:36 am

Part L of the Building Regulations (Conservation of Fuel and Power) is changing again for schemes in England, with effect from 6 April 2014.

Current schemes can still go ahead and be built to the current 2010 standards provided that the following transitional provisions are met:

  • An Initial Notice is submitted before 6 April 2014, and
  • Works on site commence before 6 April 2015

The implications for missing these deadlines (and building to the new standards) are:

  • Non-domestic new build – 9% more efficient than current
  • Domestic new build – 6% more efficient than current
  • Fabric Energy Efficiency Standards (FEES) are to be introduced, to ensure good levels of fabric insulation – a ‘fabric first’ approach

If you would like to talk to us about pre-registering your current schemes by submitting an Initial Notice and taking advantage of the transitional provision then please contact us on 01780 460464, or email
