How is the City & Guilds 6189 Level 2 qualification assessed?

It is assessed by on-screen e-volve multiple-choice knowledge tests for each knowledge unit, simulated practical assessments, and a workplace NVQ portfolio that is internally assessed and externally verified. It is not a single timed examination.

What pass mark do I need for the 6189 e-volve knowledge tests?

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.

Do I need a job to do the 6189 Level 2 NVQ?

Yes. As an NVQ it requires real workplace evidence, so you must be employed or on a work placement in plumbing and heating to build your portfolio. There are no formal academic entry requirements.

How is Level 2 different from the 6189 Level 3?

Level 2 builds core competence and underpinning knowledge across cold water, hot water, heating, drainage and rainwater systems. Level 3 goes further into advanced design, commissioning, fault diagnosis and complex systems to qualify you as a plumbing and heating engineer.

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.

1Which UK legislation places the primary general duty on employers to ensure, so far as is reasonably practicable, the health, safety and welfare of employees at work?

A.The Construction (Design and Management) Regulations 2015

B.The Health and Safety at Work etc. Act 1974

C.The Building Regulations 2010

D.The Water Supply (Water Fittings) Regulations 1999

Explanation: The Health and Safety at Work etc. Act 1974 (HASAWA) is the primary umbrella legislation, placing a general duty on employers under Section 2 to protect the health, safety and welfare of employees 'so far as is reasonably practicable'. CDM 2015 and the Building/Water Regulations are made under or sit alongside it but are not the primary general duty.

2Under the hierarchy of control, what should always be the FIRST option considered when managing a workplace hazard?

A.Provide personal protective equipment (PPE)

B.Eliminate the hazard

C.Introduce safe systems of work

D.Provide training and supervision

Explanation: The hierarchy of control requires you to try to eliminate the hazard completely before anything else. Only if elimination is not reasonably practicable do you move down through substitution, engineering controls, administrative controls and finally PPE, which is always the last resort.

3Which set of regulations specifically requires employers to assess and control the risks from hazardous substances such as flux, solvent cement and dust?

A.RIDDOR 2013

B.COSHH 2002

C.PUWER 1998

D.LOLER 1998

Explanation: The Control of Substances Hazardous to Health (COSHH) Regulations 2002 require employers to assess and control exposure to hazardous substances, including plumbing materials such as soldering flux, solvent (cold) cement and respirable dust. A COSHH assessment and safety data sheets guide safe use.

4A plumber is seriously injured on site and is unable to work for more than seven consecutive days. Under which regulations must this be reported?

A.COSHH 2002

B.RIDDOR 2013

C.Manual Handling Operations Regulations 1992

D.The Work at Height Regulations 2005

Explanation: The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR) 2013 require certain workplace injuries to be reported to the HSE. An 'over-seven-day' injury, where someone is incapacitated for more than seven consecutive days (not counting the day of the accident), is a reportable injury.

5What is the main purpose of a Permit to Work system on a building services site?

A.To record the cost of labour for invoicing

B.To formally control high-risk activities and ensure precautions are in place before work starts

C.To order materials from the merchant

D.To certify that an apprentice has passed their assessment

Explanation: A Permit to Work is a formal documented procedure used to control high-risk activities such as hot works, work in confined spaces or on live systems. It ensures hazards have been identified, precautions are in place and the right people authorise the work before it begins.

6When carrying out hot works such as soldering or using a blowtorch, what control is most important to reduce the risk of fire?

A.Wear a high-visibility vest

B.Keep a suitable fire extinguisher to hand and monitor the area after finishing

C.Open all windows in the building

D.Use a larger gas cylinder

Explanation: Hot works require a suitable fire extinguisher kept within reach, removal of combustible materials, use of a heat-resistant mat and a fire watch (monitoring the area for at least an hour after work finishes), as smouldering can ignite long after the flame is removed. Many sites require a hot-works permit.

7Which class of fire extinguisher, identified by a blue label in the UK, is suitable for fires involving electrical equipment AND most other fire types?

A.Water (red)

B.Foam (cream)

C.Dry powder (blue)

D.Wet chemical (yellow)

Explanation: Dry powder extinguishers carry a blue label and are multi-purpose, suitable for Class A, B and C fires and for electrical fires. They are versatile but create a residue, so CO2 (black) is often preferred for sensitive electrical equipment.

8Before working from a stepladder or access tower, which regulations primarily govern the precautions you must take?

A.The Work at Height Regulations 2005

B.COSHH 2002

C.RIDDOR 2013

D.The Gas Safety (Installation and Use) Regulations 1998

Explanation: The Work at Height Regulations 2005 require employers and workers to plan, supervise and carry out all work at height safely, including selecting suitable access equipment such as ladders, stepladders and towers, and ensuring it is inspected and used correctly.

9What does a safety data sheet (SDS) supplied with a plumbing product such as solvent cement primarily provide?

A.The retail price and stock code

B.Information on hazards, safe handling, storage, first aid and disposal

C.A guarantee of how long the product will last

D.The manufacturer's marketing brochure

Explanation: A safety data sheet provides standardised information on a substance's hazards, composition, safe handling and storage, first-aid measures, fire-fighting measures and disposal. It is a key input to a COSHH assessment so the substance can be used safely.

10When manually lifting a heavy radiator or boiler, which technique reduces the risk of musculoskeletal injury?

A.Keep the load away from your body and twist as you lift

B.Bend the back and keep the legs straight

C.Keep the back straight, bend the knees and hold the load close to your body

D.Lift quickly using a jerking movement

Explanation: Safe manual handling under the Manual Handling Operations Regulations 1992 requires keeping the back straight, bending at the knees and hips, and holding the load close to the body's centre of gravity. You should avoid twisting and, where possible, use mechanical aids or team lifting.
