Building Regulations latest changes...

The 2010 versions of Part L, F & J have now been published, along with the transitional provisions to be applied at their introduction on the 1^st October 2010.

Part F: Ventilation.

Part J: Combustion appliances and fuel storage systems.

Part L1A: Conservation of fuel and power New dwellings.

Part L1B: Conservation of fuel and power Existing dwellings.

Part L2A: Conservation of fuel and power New buildings other than dwellings.

Part L2B: Conservation of fuel and power Existing buildings other than dwellings.

As expected there are new requirements for:

• Testing of mechanical air flow rates in dwellings
• Commissioning of mechanical ventilation systems
• Information relating to mechanical ventilation systems to be supplied to the building owner
• TER / DER calculations and specifications to be submitted to the building control body before work starts on site
• Carbon monoxide alarms where combustion appliances are installed

A more detailed review of the main changes and implications for designers and builders will be published by NHBC shortly.

The 2010 amendments do not apply to:

• Sites where work has already started, prior to the 1^st October 2010, or
• Sites where an Initial Notice has been issued, prior to the 1^st October 2010, providing work starts on site before the 1^st October 2011.

The published transitional arrangements mean you will not need to obtain a Plans Certificate for a scheme prior to the 1^st October 2010, just ensure an Initial Notice is served.
