Topic Overview
The City & Guilds Level 1 Award in Construction Skills provides an essential foundation for anyone considering a career in the construction industry. This qualification covers the basic principles of health and safety, tool and material identification, and fundamental construction techniques across multiple trades including bricklaying, carpentry, and painting and decorating. It is designed to give learners a broad understanding of the construction environment and the practical skills needed to progress to further study or an apprenticeship.
This award is particularly important because construction is a major sector of the UK economy, employing over 2 million people. By completing this qualification, students demonstrate their commitment to safety and their ability to work effectively in a team. The course also introduces key concepts such as interpreting basic drawings, measuring and marking out, and using hand tools correctly. These skills are transferable across many construction roles and form the building blocks for more advanced qualifications like the Level 2 Diploma in Construction.
The qualification is structured around practical assessments and a multiple-choice test covering health and safety. Students will spend time in a workshop environment, learning by doing under the supervision of experienced instructors. This hands-on approach ensures that learners not only understand theory but can apply it safely and accurately. Successful completion of this award can lead to progression onto a Level 2 Diploma or an apprenticeship in a specific trade.

Assessment Guidance
Guidance for achieving higher grades
- 💡Always establish a plumb line before hanging wallpaper to ensure vertical accuracy.
- 💡Use a sharp snap-off knife for clean cuts at corners and along skirting edges.
- 💡Check paste instructions for soaking time to avoid shrinkage after hanging.
- 💡Apply paint to skirting in long, even strokes, working from top to bottom.
- 💡Conduct a final quality check, touching up any minor flaws before declaring the task complete.
- 💡Practice cutting wallpaper accurately for angles.
- 💡Use a good quality brush for skirting painting.
- 💡Keep work area tidy to avoid accidents.
- 💡Practice cutting and hanging wallpaper on corners to build confidence.
- 💡Use a plumb line to ensure the first length is vertical.
- 💡Always clean brushes and rollers thoroughly after use.
- 💡Set up your work area methodically: lay dust sheets, organize tools, and check for hazards before starting any task.
- 💡When wallpapering external corners, wrap the paper around by at least 25mm and mark a plumb line on the adjacent wall to keep the next length vertical.
- 💡For crisp skirting edges, lightly score along the masking tape edge before removal to prevent peeling, and use a cutting-in brush for precision.
- 💡Demonstrate continuous adherence to health and safety, such as wearing goggles when sanding and safely disposing of sharp blades, as assessors note this throughout.
- 💡Measure and mark wallpaper carefully, allowing a little extra for trimming at angles for a precise fit.
- 💡Use a sharp snap-off knife and a straight edge to cut wallpaper cleanly, especially when dealing with external corners.
- 💡For painting skirting, apply paint in thin, even coats and use a mini roller for flat sections to avoid brush marks.
- 💡Keep the workspace tidy throughout: use dust sheets, vacuum sanding dust, and store tools safely to demonstrate good housekeeping.
- 💡Always read the assessment brief carefully to understand the specific requirements for substrate preparation and finish quality—marks are often lost by missing preparatory steps.
- 💡Take your time when measuring and cutting wallpaper for corners; it's better to cut slightly long and trim precisely than to have gaps. Use a sharp blade and straight edge.
- 💡When painting skirting, apply thin, even coats and check for runs before moving on. Mask the wall above if necessary to protect the wallpaper.
- 💡Document your safe working practices throughout the task, as this evidence can be crucial for achieving the health and safety criteria in your portfolio.
- 💡When hanging wallpaper around external angles, always allow a 25mm overlap to trim back for a perfect butt joint, ensuring the pattern aligns before cutting.
- 💡Use a sharp retractable knife and a straight edge to trim skirting paint lines cleanly, demonstrating precision to the assessor.
- 💡Plan your work sequence to avoid contamination—complete wallpapering before painting skirting to prevent paste or paper adhesive from spoiling the painted finish.
- 💡In the practical assessment, focus on accuracy and safety over speed. Examiners are looking for correct technique and attention to detail. Rushing leads to mistakes and can be dangerous.
- 💡For the multiple-choice test, read each question carefully and eliminate obviously wrong answers first. Many questions test your knowledge of key terms and definitions, so make sure you understand the meaning of words like 'hazard', 'risk', and 'COSHH'.
- 💡Keep your work area tidy throughout the practical assessment. A clean workspace shows that you are organised and safety-conscious, which examiners note positively.
Common Mistakes
Common errors to avoid in your coursework
- Skipping surface preparation, leading to poor adhesion and visible imperfections.
- Misaligning wallpaper pattern at internal corners, causing a mismatched appearance.
- Applying adhesive unevenly or using the wrong type, resulting in bubbles or peeling.
- Painting skirting without masking adjacent surfaces, causing accidental paint transfer.
- Failing to clean brushes and tools immediately after use, leading to damage and contamination.
- Poor pattern matching at angles.
- Leaving brush marks on skirting paint.
- Not protecting floors and furniture from paint spills.
- Failing to allow for pattern match when cutting wallpaper.
- Applying too much paste, causing wallpaper to stretch or tear.
- Painting skirting without proper preparation, leading to poor adhesion.
- Failing to account for pattern repeat when cutting wallpaper, resulting in mismatched patterns at internal angles.
- Overlapping wallpaper excessively at external angles, causing unsightly ridges, or cutting it too short, leading to peeling edges.
- Applying paint to skirting without adequate masking, causing splashes or overpainting onto walls and floors.
- Omitting essential preparation steps like sanding gloss skirting or knotting resinous timber, which leads to poor paint adhesion and bleeding.
- Not wiping off excess paste from the face of wallpaper or skirting, leaving shiny marks after drying.
- Not allowing filler to dry fully before sanding, leading to an uneven base for wallpaper and paint.
- Cutting wallpaper too short or failing to trim neatly into corners, leaving gaps or overlapping edges.
- Applying paint too thickly on skirting, causing drips and an orange-peel effect.
- Neglecting to cover floors and furniture, resulting in paint splashes and a messy work area.
- Skipping surface preparation such as sanding or priming, leading to poor paint adhesion and uneven wallpaper finish.
- Misjudging wallpaper cuts at corners, resulting in gaps, overlaps, or torn edges that compromise the professional appearance.
- Overloading the brush with paint when coating skirting, causing drips, sags, and an unprofessional streaky finish.
- Failing to protect floors and adjacent surfaces with dust sheets, leading to spillages and time-consuming clean-up.
- Using the off-cut from an internal angle to wrap around an external angle without checking for pattern alignment, leading to mismatched seams.
- Applying wallpaper paste too sparingly or unevenly, causing edges to lift at angles and corners.
- Painting skirting boards before adequately sanding and priming, resulting in poor adhesion and an uneven finish.
- Failing to cut in accurately along the skirting edge with the wall, leaving gaps or paint on the wall surface.
- Misconception: Health and safety rules are just red tape that slow down work. Correction: Health and safety procedures are designed to prevent accidents and save lives. Following them correctly actually improves efficiency by reducing downtime from injuries and ensuring work is done right first time.
- Misconception: You don't need to measure twice if you're experienced. Correction: Even experienced tradespeople measure twice to avoid costly mistakes. Accurate measurement is a fundamental skill that prevents waste and ensures materials fit properly.
- Misconception: All hammers are the same. Correction: Different hammers are designed for specific tasks. For example, a claw hammer is for driving and removing nails, while a club hammer is used with chisels for cutting bricks or concrete. Using the wrong tool can damage materials or cause injury.
