Protect the Continued Use of BTU Measurements in the UK Heating Industry

BTU has been the standard reference across the heating industry for decades and remains widely understood by manufacturers, suppliers, installers, and consumers. A shift toward watt-only specifications risks confusion, costly retraining, and disruption to established practices and systems. Many existing installations and specifications rely on BTU, and removing it could create inefficiencies, errors, and unnecessary expense. Retaining both units supports consistency, and a smoother transition.
