Why “reasonable skill and care” matters in disputes
If you act for a client in a landscaping dispute, you will often see the same phrase repeated. The contractor must exercise “reasonable skill and care”. However, that wording can feel subjective unless it is tested properly. That is why an independent expert assessment is often pivotal. It converts opinion into evidence. It also helps the parties understand whether the issues arise from workmanship, design, materials, or maintenance.
What the court is usually trying to establish
In most cases, the court is not looking for perfection. Instead, it is assessing whether the works were completed to a reasonable professional standard. Therefore, the key question becomes simple. Would a competent contractor, acting with reasonable skill and care, have produced the same outcome? If not, the next question follows. What should have been done differently, and why?
How an expert assesses workmanship objectively
A competent assessment must be evidence-led. For example, I will review the contract documents, drawings, specifications, and photographs. I will then compare the installation against recognised best industry practice. Where relevant, I will also reference applicable British Standards and manufacturer guidance. As a result, the analysis becomes measurable and defensible. It moves away from personal preference and towards objective benchmarks.
Common indicators of a departure from reasonable standards
Landscaping failures are rarely random. Instead, they tend to fall into repeatable patterns. These include inadequate falls and poor water control, weak sub-base construction, poor edge restraint, and inconsistent levels. In addition, defects often arise at interfaces. Thresholds, DPC relationships, drainage transitions, and detailing around posts are common problem areas. Importantly, workmanship may look acceptable at first glance, yet still fail due to poor design or poor supervision.
The role of design and supervision in landscaping outcomes
Reasonable skill and care is not limited to laying slabs neatly. It also includes planning, sequencing, and competent supervision. For instance, correct levels must be set before construction begins. Likewise, drainage routes must be designed and formed to discharge water safely. If these fundamentals are missing, the finished garden may look complete, but still perform poorly. Therefore, a proper assessment must consider design intent and site management, not only the visible surface.
What lawyers need from an independent expert witness
Solicitors need clarity, structure, and reliability. They need an expert who understands duty to the court and provides a report that is compliant, balanced, and properly reasoned. In addition, they need conclusions that can withstand scrutiny. That includes clear causation, proportionate remedial recommendations, and where required, a sound basis for quantum.
When early instruction saves time and cost
In many disputes, early expert input reduces escalation. A pre-action technical report can narrow issues quickly. It can also support negotiation or ADR. However, where proceedings require it, a CPR Part 35 report provides the court with independent opinion evidence. Either way, the objective remains the same. Establish what happened, why it happened, and what is reasonable.
