Learning Objectives
What you need to know and understand
- Know how to carry out electrical repairs.Know how to carry out repairs to damaged or defected electrical components and appliances.Know how to carry out replacements to damaged or defected electrical components and appliances.Know the problems that can occur when carrying out electrical trade maintenance replacements
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating a systematic approach to fault finding, including visual inspection and use of appropriate test equipment.
- Evidence should show correct isolation and locking-off of electrical supplies before commencing any repair or replacement.
- Look for selection of replacement components that match original specifications in rating, type, and safety compliance (e.g., same fuse rating, IP rating).
- Assessor to expect post-repair testing and verification of functionality, including continuity and insulation resistance tests where applicable.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always reference the Electricity at Work Regulations and BS 7671 when describing safe isolation and repair procedures in written assessments.
- 💡In practical observations, narrate your actions clearly: state that you are isolating the circuit, verifying voltage absence, and using appropriate personal protective equipment.
- 💡When discussing replacement tasks, emphasise the importance of matching component specifications and maintaining the appliance's original safety features.
- 💡Prepare to explain common problems like intermittent faults, incorrect polarity, or damaged insulation, and how you would methodically identify and resolve them.
- 💡Always use correct technical terminology in your answers, such as 'damp-proof course', 'substrate', 'abrasive paper', etc. This shows the examiner you have the required knowledge.
- 💡For calculation questions, show all your working out, even if you make a mistake. You can gain method marks for correct steps even if the final answer is wrong.
- 💡When answering questions about repairs, always consider the cause of the problem, not just the symptom. For example, if plaster is damp, identify the source of moisture before re-plastering.
Common Mistakes
Common errors to avoid in your coursework
- Assuming a component is faulty without performing basic checks, such as verifying the integrity of the supply or the condition of protective devices.
- Replacing a component with an incorrect one, e.g., a switch that does not match the current rating or an appliance part that is not approved for the specific model.
- Forgetting to tighten terminal screws to the correct torque, leading to loose connections and potential overheating.
- Overlooking the need for functional testing after repair, resulting in undetected faults or unsafe conditions.
- Misconception: Plastering is just about applying plaster to a wall. Correction: It requires proper surface preparation, mixing ratios, and techniques like floating and troweling to achieve a smooth finish.
- Misconception: All damp problems can be solved by installing a damp-proof course. Correction: Damp can be caused by condensation or penetrating water, which require different solutions like ventilation or external repairs.
- Misconception: Health and safety is just common sense. Correction: It involves specific legal requirements, risk assessments, and control measures that must be followed to prevent accidents and comply with the law.
Revision Plan
How to revise this topic in 1–2 weeks
- 1Week 1: Focus on health and safety legislation and risk assessment. Create flashcards for key terms like COSHH, RIDDOR, and PUWER. Practice writing risk assessments for common maintenance tasks.
- 2Week 2: Study building construction and damp/timber defects. Use diagrams to label parts of a wall and understand damp-proof courses. Watch videos on identifying damp types.
- 3Week 3: Practice multi-trade repair techniques. If possible, get hands-on experience with plastering or tiling. Otherwise, watch tutorials and take notes on step-by-step processes.
- 4Week 4: Review past papers and practice calculation questions. Time yourself to improve speed. Focus on command words like 'state', 'explain', and 'calculate'.
- 5Week 5: Consolidate learning by teaching a friend or writing summaries. Take mock exams and identify weak areas for final revision.
Exam Question Types
How this topic typically appears in the exam
- 📋Multiple-choice questions: Test recall of facts, such as the correct PPE for a task or the definition of a term. Read each option carefully and eliminate obviously wrong answers.
- 📋Short-answer questions: Require a brief explanation, e.g., 'State two causes of condensation.' Be concise and use correct terminology.
- 📋Calculation questions: Involve area, volume, or cost. Show your working and include units in your final answer.
- 📋Scenario-based questions: Present a maintenance problem and ask for diagnosis and repair. Use a structured approach: identify the issue, explain the cause, and describe the repair method.
Command Word Expectations (GQA QUALIFICATIONS LIMITED)
What examiners look for when using specific command words in this specification
Provide a brief, factual answer without explanation. For example, 'State one type of damp.' Answer: 'Rising damp.'
Give a reason or cause. For example, 'Explain why condensation occurs.' Answer: 'Condensation occurs when warm, moist air meets a cold surface, causing water vapor to turn into liquid water.'
Perform a mathematical calculation and show your working. Include units in the final answer. For example, 'Calculate the area of a wall 3m by 2m.' Answer: 'Area = 3 × 2 = 6 m².'

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A wall measures 4.5 m in length and 2.4 m in height. It requires re-plastering. Calculate the area of the wall in square metres. If the plasterer charges £12 per square metre, what is the total cost?
- 1.Step 1: Identify the given dimensions: length = 4.5 m, height = 2.4 m.
- 2.Step 2: Calculate the area using the formula: Area = length × height = 4.5 × 2.4 = 10.8 m².
- 3.Step 3: Multiply the area by the cost per square metre: 10.8 × £12 = £129.60.
- 4.Step 4: State the final answer with units: The total cost is £129.60.
Question: A room has a floor area of 20 m² and a ceiling height of 2.5 m. Calculate the volume of the room in cubic metres. If the air change rate required is 3 air changes per hour, what is the required ventilation rate in m³/hour?
- 1.Step 1: Identify the given facts: floor area = 20 m², height = 2.5 m, air changes per hour = 3.
- 2.Step 2: Calculate the volume: Volume = area × height = 20 × 2.5 = 50 m³.
- 3.Step 3: Multiply the volume by the air change rate: 50 × 3 = 150 m³/hour.
- 4.Step 4: State the final answer: The required ventilation rate is 150 m³/hour.
