Part L Building Regulations

BS7593 underpins best practice in relation to heating and cooling systems and is being incorporated into Part L of the Building Regulations. The Building Regulations centre around the conservation of energy and now improving energy efficiency in not just new properties, but all homes. This changes BS7593 from being an advisory document to being regulation. This means that it isn’t a legal requirement but is a strong recommendation.
