Future Homes Standard Consultation

Future Homes and Buildings Standard consultation

More than three years has now passed since the Part L 2021 consultation. The Government's decision to ban fossil fuel based energy is evidence that responding to this previous consultation was worth the amazing collective effort.

The government have now released the Future Homes and Buildings Standards: 2023 consultation covering Part L (conservation of fuel and power), Part F (ventilation) and Part O (overheating). In addition there are supporting consultations on the Home Energy Model: replacement for the Standard Assessment Procedure and Home Energy Model: Future Homes Standard assessment.


While we welcome an end to the use of fossil fuels, we believe these proposed changes do not go far enough.  We are shocked at the addition of a loop-hole that would enable local authorities to allow new buildings to opt-out of achieving minimum Part L performance requirements.  We are also disappointed by the continued use of carbon emission and primary energy metrics; avoidance of accounting for unregulated energy; and the use of a notional building methodology.

If the proposals are enacted in their current state, we will be creating a generation of inefficient buildings that are not creating the resilient, equitable country that we deserve.


LETI's response to the Future Homes Standard Consultation is ready!  Now, we need your help to make our voices heard and meet our climate commitments!
