The City & Guilds 6189 Level 2 NVQ Diploma in Plumbing & Heating is the foundation qualification for the plumbing and heating trade in the UK and the core of the apprenticeship. It is not a single timed exam: learners sit on-screen e-volve multiple-choice knowledge tests for each unit, complete simulated practical assessments, and build a workplace NVQ portfolio that is internally assessed and externally verified. Knowledge content spans health and safety (HASAWA, COSHH, RIDDOR, work at height), environmental awareness and sustainability, communication, scientific principles (heat, pressure, materials), cold water systems and the Water Fittings Regulations, hot water systems including unvented (G3), central heating, above-ground drainage and sanitation, and rainwater systems. This free prep includes 100 research-based practice questions with explanations and an AI tutor, grounded in UK standards such as the Water Regulations, BS EN 806 and Building Regulations Parts G and H.

The pass mark is set per unit by City & Guilds and is typically in the region of 60-70% for the on-screen multiple-choice tests. Your training centre will confirm the exact mark for each unit, so balanced revision across every topic is essential.
What does the 6189 Level 2 cover?
It covers health and safety, environmental awareness and sustainability, communication, scientific principles (heat, pressure and materials), cold water systems and the Water Fittings Regulations, hot water systems including unvented (G3), central heating, above-ground drainage and sanitation, and rainwater systems.
