Future Homes Standard


It’s time to rethink HVAC specification. 


Before the end of 2021, industry will need to adapt HVAC strategies and building design in order to adhere to new compliance regulations. 

This is in the wake of the Government’s consultation to update Part L and Part F of the Building Regulations for new residential developments. 

The aim of this consultation was to begin aligning the built environment with the future direction of UK sustainability policy – changing compliance targets, planning requirements and, ultimately, the way we supply heat and clean air to new homes. 

With Part L and Part F 2020 becoming legally enforceable, do you have your new HVAC strategy ready?


When will I need to comply with these changes?
Government is expected to publish the final document containing new Part L and Part F Regulations mid-2020, including any consultation changes to their original proposal. This is then expected to become legally enforceable before the end of the year.
What are the proposed compliance metrics?
The consultation proposed four compliance metrics for new developments: primary energy, carbon emissions, affordability and minimum standards for building fabric and building services.
What’s the difference between Option 1 and Option 2?

Industry was given the chance to review how challenging they wanted the update to Part L to be, by stating whether they would prefer a 20% or 31% uplift in carbon emission targets compared to 2013 standards. This will not change the minimum standards for U-values.

The need for a new strategy

The Government’s proposed update to Part L and Part F is driven by four main goals, all of which affect HVAC specification and aid towards the achievement of future environmental targets: 

  • Align with future targets for new houses (a 75-80% carbon reduction target in 2025)
  • Simplify guidance to make the Building Regulations clearer to understand 
  • Reduce the performance gap of new dwellings 
  • Comply with the Energy Performance of Buildings Directive 

In order to do this, there are significant changes to the requirements for new dwellings; including the introduction of four compliance targets and a shift in the way ventilation systems are specified and designed.
