Quick Revision Summary (Key Takeaway)
The Lantra Awards Level 2 Diploma in Work-based Fencing – General Fencing (Non-strained Systems) covers the safe and competent installation of non-strained fencing systems, including post and rail, panel, and temporary fencing. It emphasises practical skills, risk assessment, and compliance with UK regulations, preparing learners for a career in agricultural, residential, or commercial fencing.
Topic Overview
General fencing (non-strained systems) is a fundamental skill in the land-based and construction sectors. This unit of the Lantra Awards Level 2 Diploma focuses on the installation of fencing that does not rely on tensioned wire, such as post and rail, panel, and temporary fencing. These systems are widely used for demarcating boundaries, securing livestock, and enhancing aesthetics in residential and rural settings. The qualification emphasises practical competence, from selecting materials to finishing techniques, ensuring you can work safely and efficiently on site.
Why does this matter? Non-strained fencing is often the first choice for many applications because it is simpler to install and maintain than strained systems. However, it still requires precision: correct post spacing, proper jointing, and attention to ground conditions are essential for durability. This unit also covers relevant health and safety legislation, environmental considerations, and customer communication, making you a well-rounded fencing operative. Mastery of these skills opens doors to roles in agricultural contracting, landscaping, and construction.
In the wider context of the diploma, this unit complements other areas like strained fencing and gate installation. It builds your understanding of site preparation, tool use, and quality standards, which are transferable across all fencing types. By the end, you should be able to plan a fencing project, estimate materials, and execute the installation to industry standards, ready for assessment in the workplace.
Key Concepts
Core ideas you must understand for this topic
- →Non-strained systems: fencing that uses rigid components (rails, panels, boards) fixed to posts without tensioning wires.
- →Post setting: correct depth (one-third of post length), use of gravel for drainage, and concrete mix ratios for stability.
- →Material selection: types of timber (e.g., treated softwood, hardwood), panel types (feather edge, closeboard), and fixings (galvanised nails, brackets).
- →Health and safety: risk assessments, PPE, safe use of tools, and working near public areas or services.
- →Quality checks: ensuring posts are plumb, rails are level, and fixings are secure to meet British Standards (e.g., BS 1722).

Assessment Guidance
Guidance for achieving higher grades
- 💡For assessment, always begin by clearly verbalising the pre-start checks: confirming underground services are clear, selecting the right tools and PPE, and inspecting the posts and driving equipment for defects.
- 💡Structure your practical demonstration by explaining the step-by-step sequence: measure and mark, position the post, drive part way, check plumb on two adjacent faces, adjust if needed, then drive to final depth while maintaining alignment.
- 💡Use consistent terminology and refer to the importance of achieving uniform post heights and spacing for a professional finish; mention that non-strained systems rely on each post’s individual stability.
- 💡Reference relevant health and safety regulations, such as the Provision and Use of Work Equipment Regulations (PUWER) for tool safety, and the Construction (Design and Management) Regulations for task planning.
- 💡Always cross-reference the job specification or drawing before starting to confirm post positions, spacing, and required depth.
- 💡Use a taut string line and check alignment frequently—after every few strikes—to catch and correct deviations early.
- 💡Select a post driver of appropriate weight; a heavier driver can reduce effort and improve accuracy in firm ground.
- 💡Practice consistent, controlled strikes centred on the post top to avoid glances that cause misalignment or damage.
- 💡In assessment, verbally explain your choice of tools and safety checks to demonstrate underpinning knowledge, even if not directly assessed.
- 💡Always quote specific measurements and ratios, such as post depth (one-third of length) or concrete mix (1:4). This shows precise knowledge.
- 💡In practical assessments, demonstrate a methodical approach: measure, mark, set out, then install. Examiners look for planning skills.
- 💡Link your answers to relevant standards like BS 1722 or the Health and Safety at Work Act to gain higher marks.
Common Mistakes
Common errors to avoid in your coursework
- Assuming a sledgehammer is suitable for all post sizes; larger or harder posts often require a post driver or rammer to avoid splitting and to drive effectively.
- Neglecting to check for underground utilities (gas, water, electric) before driving posts, which can lead to serious accidents and service disruptions.
- Failing to brace or support the post during initial driving, causing it to lean or twist, and then attempting to correct it when already deep, resulting in a loose fit.
- Misjudging the required driving depth, leading to unstable posts that may shift under load, or driving too deep and wasting material.
- Ignoring soil conditions, such as rocky or very soft ground, without adapting technique (e.g., using a pilot hole or different driving method), which can cause post damage or poor anchorage.
- Failing to check for underground services before driving posts, which can lead to service strikes and serious injury.
- Using incorrect striking technique or excessive force, causing post damage (e.g., splitting, mushrooming) or personal strain.
- Not maintaining consistent post depth, resulting in uneven fence height and weak structural points in the strained system.
- Allowing posts to drift out of line during driving, which will affect wire tension and overall fence straightness.
- Underestimating ground conditions and failing to adjust technique or equipment, leading to insecure posts that may lean or fail under strain.
- Misconception: Non-strained fencing doesn't need to be as strong as strained fencing. Correction: While it doesn't use tension, it still must withstand wind and impact; proper post depth and concrete are crucial.
- Misconception: You can use any type of timber for fencing. Correction: Timber must be pressure-treated or naturally durable (e.g., oak) to resist rot and insect attack, especially in ground contact.
- Misconception: Panels can be fixed directly to posts without brackets. Correction: Using appropriate brackets or nails at correct angles ensures a secure fit and prevents splitting.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A customer requires a 20-metre run of post and rail fencing with posts at 2-metre centres. Calculate the number of posts needed and the number of rails required if each rail is 3 metres long. Show your working.
- 1.Step 1: Identify the total length and post spacing: 20 metres total, 2 metres apart.
- 2.Step 2: Calculate number of posts: (20 / 2) + 1 = 11 posts (including end posts).
- 3.Step 3: Calculate number of rails per bay: each bay is 2 metres, but rails are 3 metres long, so one rail can cover one bay with overlap? Actually, for post and rail, rails are typically cut to fit between posts, so each bay needs one rail per level. If using 3-metre rails, you can cut them to 2 metres, but for calculation, assume one rail per bay per level. For a 3-rail fence, total rails = (number of bays) * 3 = 10 * 3 = 30 rails. But if rails are 3m long and you cut to 2m, you get 1 rail per bay per level. So 30 rails needed.
- 4.Step 4: State final answer: 11 posts and 30 rails (for a 3-rail fence).
Question: Describe the correct procedure for setting a timber post in concrete for a panel fence, including the mix ratio and curing time.
- 1.Step 1: Dig a hole to the required depth – typically one-third of the post length, plus 100mm for gravel drainage.
- 2.Step 2: Place 100mm of gravel at the bottom for drainage to prevent rot.
- 3.Step 3: Position the post in the hole, ensuring it is plumb using a spirit level, and brace it temporarily.
- 4.Step 4: Mix concrete using a ratio of 1 part cement to 4 parts ballast (or 1:2:4 cement:sand:aggregate) with water to a workable consistency.
- 5.Step 5: Pour the concrete around the post, tamping it down to remove air pockets, and slope the top away from the post to shed water.
- 6.Step 6: Allow the concrete to cure for at least 24-48 hours before attaching panels, and ideally 7 days for full strength.
